EXTRA MARKET VALUES FOR NON-CONSUMPTIVE USES OF FOUR GREAT LAKES REGION WILDLIFE SPECIES By Cathleen Heidi Grether A THESIS Submitted to Michigan State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Department of Resource Development 1984 ABSTRACT EXTRA MARKET VALUES FOR NON-CONSUMPTIVE USES OF FOUR GREAT LAKES REGION WILDLIFE SPECIES By CATHLEEN HEIDI GRETHER Extra market values for non-consumptive uses of fish and wildlife resources are important elements in resource allocation decisions. Presently, there are no estimates for these types of values for Great Lakes region species. This study explores Ingham and Bay county respondents' use, option price and existence values for four species associated with the Great Lakes. The contingent valuation method was used to elicit respondents' values; and two types of interviews were used: telephone and personal interviews. Telephone interviews were conducted in Bay and Ingham coun- ties, whereas personal interviews were conducted only in Ingham county. Major finding of this study include that: individuals do hold extra market values for fish and wildlife resources; these values are, on average, positive; existence values are of the some order of magni- tude as use values; and generally, bald eagles are valued the highest while the value of gulls is relatively low. ACKNOWLEDGEMENTS I would like to thank the members of my graduate committee for their guidance during this study: Drs. Daniel R. Talhelm, Milton H. Steinmueller and Lawrence Libby. In addition, I would like to express my gratitude to my fellow graduate students in Resource DevelOpment. Many provided frequent assistance through discussions of the merits of this study and the uses of their libraries. I would like to thank the Great Lakes Fishery Commision for providing financial support, and the MSU Fisheries and Wildlife Department, Jane Thompson in particular, for typing the questionnaire and this paper. Lastly, I am thankful for the support of my husband, Stan Koster and our families. Without them, achievement of this goal would have been impossible. ii CHAPTER I: CHAPTER 11: CHAPTER III: CHAPTER IV: CHAPTER V: Appendix A1: Appendix A2: Appendix A3: Appendix Bl: Appendix 82: Appendix C1: Appendix CZ: Appendix D: TABLE OF CONTENTS Introduction . . . . . . .......... . .

The value of consumptive use of the resource is the value associated with the physical consumption of it; examples include the value of a timber stand for pulp wood and the price per pound of Atlantic salmon. The non-consumptive use value of the resource is value attributed to the uses of resource that do not physi- cally affect the resource; examples include the value of saving an endangered species from extinction or the value of preserving wilderness areas (Randall 1981). Economic values most often associated with the use of natural resources have been consumptive use values. The value of the consump- tive use of the resource is the price the buyer or user is willing to pay for it in a market. This value, as with all values, depends upon the total supply and demand of the resource. Many pe0ple value non-consumptive uses of natural resources. These values are somewhat intangible because they are difficult to define or identify and they are not transacted in a market. Therefore, they have been termed extra market values. Historically, policy analysts have sometimes employed benefit-cost studies to determine the most economically efficient allocations of natural resources. Monetary values used in these analyses have gen- erally been tangible values derived from some observable market interac- tion. The consideration of only market established use values omitted many other social values. Increased awareness of this deficiency has led to efforts to include intangible social values as part of benefit- cost analysis. It is especially important that the extra market values for non- consumptive uses of wildlife be examined, as wildlife resources can be utilized in many ways in addition to consumption. If individuals hold these kinds of values, the values need to be identified and included in benefit-cost evaluations. Estimating these non-consumptive use values can provide policy makers with a more complete set of tools for resource allocation decisions. It is also important to point out that non-consumptive values of wildlife may be based on a broad range of experiences, interests and feelings. The total value for a given item or experience may be separated into three mutually exclusive components (Talhelm 1983, Ran- dall and Stoll 1983, Talhelm and Johnson 1984). Specifically, total value is comprised of use value, option value and existence value, where: use value is the value an individual places on his/her present and future use of the resource; option value is the value an individual places on the guarantee itself of the future availability of the resource for his/her possible use or enjoyment, in addition to his/her present and future use value; and existence value is the value an indi- vidual places on knowing the resource will exist now and in the future even though he/she may never enjoy the resource directly. Option price is equal to the option value plus the expected consumer surplus of the future use of the resource. This typology of values can be applied to many categories of natural resources, including wildlife. The method of obtaining these values, however, depends on the situation or resource being investi- gated. Freeman (1979) cites two approaches to determining individuals' values for environmental quality improvements which can be applied to other natural resource valuation situations. They are: 1) ask indivi- duals for their values; and 2) derive values from related market tran- sactions. The literature is replete with studies that try to assess extra market values for natural resources. (See Brookshire and Crocker, 1981 for a summary.) In the area of wildlife resources, however, economic research has been limited primarily to values associated with consump- tive (hunted) species (Bishop and Heberlein 1979, Brookshire et al. 1982). In the Great Lakes region no research on the extra market values for non-consumptive uses of wildlife has been undertaken. This study will address the issue of non-consumptive use values for specified Great Lakes wildlife species. Scope of This Study There were several major goals of this study. First, determine if individuals are able to-conceptually divide their total value for a specified wildlife species into itsl component values and assess each component separately. Second, determine the magnitudes of the com- ponents as an approximation of their relative importance. Third, deter- mine the approximate value of each species and use this as an indicator of individuals' preferences between species. Fourth, examine the possi- bility that the relative magnitudes of the values for species may be related to other factors, including geographical location. Fifth, evaluate whether respondents were able to understand the concepts presented, and if they felt their responses accurately reflected their values. Finally, offer recommendations for further research into the problem of assessing extra market values for non-consumptive uses of wildlife. It is important to recognize that the scope of this study imposes limitations on the practical use and application of the findings. Due to the scarcity of previous studies on the value of non-consumptive uses of wildlife, and time and monetary constraints, this study was not able to unequivocally provide answers to many of the questions raised. It does however, indicate ranges and magnitudes of values, and directions for further research in the area of extra market values for non- consumptive uses of wildlife. Several questions were identified for examination at the onset of this study. These questions, in hypothesis form, are: 1. People hold option prices and existence values for fish and wildlife resources, and these valuations differ from species to species. 2. Option prices for each species differ from existence values for each species. 3. Total use values will be higher for common species (species with low utilization costs) and will be lower for uncommon species (species with high utilization costs). Two research tools were employed in this study, telephone inter- views and personal interviews. Questionnaires were developed for each interview type. In both, the components of total value were explained to each respondent. He/she was asked about the relative importance of each component, and then asked to assign a dollar value to each com- ponent. A Four wildlife species associated with the Great Lakes were chosen for the study: bald eagle (Haliaeetus leucocephalus), Great Lakes sea gull (Larus 322,), lake trout (Salvelinus namaycush), and lake sturgeon (Acipenser fulvescens). For each of the two animal classes represented (birds and fish), one common and one uncommon species was chosen so the relative total values of each species in the same class could be com- pared to each other. Personal interview respondents were asked about all four species, but, due to interview-time considerations, telephone interviewees were only asked about one species. Organization of the Paper The remainder of this paper is divided into four chapters. Chapter II provides the theoretical basis for the project by reviewing the tax- onomy of values used. Chapter 111 contains an explanation of the research methods employed and special methodology concerns specific to extra market valuations. The findings are discussed in Chapter IV, including a description of the general results, comparisons of results between survey types and examination of the results vis-a-vis the hypotheses. Chapter V presents a summary of the key findings, conclusions based on these findings and recommendations for further study and research. CHAPTER II THEORETICAL FOUNDATION The difficulty in determining extra market values for non- consumptive uses of wildlife species is a recognized problem. Due to the system of rights enjoyed in the United States, all citizens are joint owners, through the government, of many of the country's natural resources. Traditionally, many natural resources are also considered public goods. Public goods have been defined as goods that are non- rival and non-excludable (Boadway 1979), meaning that the good can be jointly used or enjoyed by more than one individual at a time, and that individuals cannot be excluded from this use or enjoyment. Allocation of public goods through market mechanisms is inefficient or impossible because of their nature. Some public goods may also be common property resourced when suffi- cient demand for use of the resource exists. Common property resources are resources in which open access and the right of capture are allowed. These characteristics provide the foundation for resource use problems. First, open access to the resource can lead to congestion arising from its' use. This is because each individual has the right of access to the resource whenever he/she desires. Second, the resource may become depleted because of the right of capture. Consequently, overexploita- tion of the resource may result with common property resources. The very nature of some natural resources, therefore, makes it inapprOpriate to use traditional market transactions to determine the resources' values to society. In these cases, other methods of resource valuation must be used. In this study, it was helpful to establish an artificial typology to aid in the examination of extra market values for non-consumptive uses of wildlife, and consumptive and non-consumptive uses of fish. This typology was based on economic theory and certain observed economic exchanges. Three mutually exclusive classes of values were established: (1) the value associated with the consumptive and non-consumptive use of the species or “use“ value, (2) the value associated with the guarantee of the future availability of the species or "option" value and (3) the value associated with the pure existence of the species or "existence" value. Use Value It is well known that individuals are willing to pay for wildlife related experiences. These wildlife experiences can be consumptive or non-consumptive in nature. Common user fees associated with consumptive uses of wildlife include hunting and fishing license fees. User fees associated with non-consumptive uses of wildlife include state and federal park permits. There may be many reasons why an individual is willing to pay a user fee, such as a park permit. Consider the example of Pt. Pelee National Park in southern Ontario, Canada. The park is heavily used by vacationers and birdwatchers. Each vehicle entering the park is 'required to purchase a $2.00 daily or $10.00 annual entry permit. The entry fee paid by vacationers may be attributed to the ability to enjoy the many miles of beaches and trails in the park, while the fee paid by birdwatchers would be attributed to the value of the non-consumptive uses of birds during migration. Additionally, some individuals may visit Pt. Pelee (and consequently pay the entry fee) for multiple rea- sons, many of which may have little or nothing to do with wildlife related experiences. In these cases, such observable "market" interactions may give insight into individuals' willingness to pay for their present and future wildlife related experiences. This insight, however, is limited because user fees are artificially low and do not include a significant component of wildlife value. In reality, individuals may be willing to pay more than the required user fees. Therefore, the user fee system does not accurately reflect individuals' consumptive or non-consumptive use value, and measurement must be obtained using a consumer surplus approach. The specific concern here is to assess the value of individuals' present and future uses for the four wildlife species under considera- tion by estimating the maximum amount they would be willing to pay for their present and future resource use. In essence then, this value is the expected consumer surplus from present and future uses of the species. Use value is defined as the amount an individual is willing to pay for his/her present and future use or enjoyment of a specified species. 10 Option Price and Option Value The notion of option value has been discussed in economic litera- ture for 20 years, originating with Weisbrod's 1964 article on Option value. Weisbrod posed the idea that people would be willing to pay for the option to retain a right or commodity presently available for use at a future time. He further stated that "option value" should be included in any economic based decision to alter or eliminate that right or com- modity (Weisbrod 1964). Through the years, much debate ensued over the nature of option value and its place in economic theory. For example, Long (1967) con- tended option value was merely a rediscovery of consumer surplus. Lindsay (1969) pointed out the element of uncertainty in option value and reinforced Weisbrod's insurance policy analogy. Byerlee (1971) attempted an empirical analysis of the option value-consumer surplus debate proposed by Long. The existence of option value was further shown by Cicchetti and Freeman (1971). Additional empirical work was done by Schmalensee (1972) and Bohm (1975). The most comprehensive review of relevant option value literature to date has been done by Bishop (1982). His work provided a clearer definition of option value and Option price. Bishop pointed out that option price is the maximum amount an individual would be willing to pay to maintain the option of using or enjoying the good (or experience) in the future. Option value, then, equals the option price minus the expected consumer surplus from future use of the good. Option value is in addition to his/her use value and is similar to the value of insurance. This is the amount an individual is willing to pay to decrease the risk that the resource will be unavailable in the future 11 should he/she decide to use it. (See Talhelm and Johnson 1984 for further explanation.) In this study, the intent was to ask respondents their option price, but given the wording and interpretation Of the questions, it is felt that a hybrid of option value and option price is asked. The option value is not calculated because the expected consumer surplus Of the Option could not be subtracted from the Option price, as it was not clearly estimated. Existence Value The idea that many individuals desire to preserve certain things for future generations is not new. It is evidenced by the paSsing on Of family heirlooms and other items Of sentimental or economic value. Similarly, some individuals may feel it is important tO preserve certain natural sites or resources for future generations to enjoy (Krutilla 1967). This desire to preserve wildlife for the future is well recognized by many of the wildlife advocacy organizations. Often, the appeal for donations is on behalf of preserving an endangered species, which most people would never have the Opportunity to see in its' natural habitat. The request is frequently along the lines of, "Help us save the white rhino from extinction - so your children can enjoy its' majestic beauty.“ This can be an effective tool for soliciting support because individuals can be motivated by the desire for their children and future generations to have the same Opportunities that are now available. For some, these appeals may imply future use value and option value as well as existence value, but to others the appeals may imply purely existence value. 12 In an effort to quantify this desire, a working definition Of existenée value was formed. The definition Of existence value used here is the maximum amount an individual would be willing to pay to ensure the existence Of a specified species without regard to his/her own future use or enjoyment. The goal in using this typology and making the transition from theory to practice, is to estimate individuals' specific use values for the four wildlife species examined. It is hoped that these approxima- tions could be used as benchmark values for researchers and policy mak- ers in the future. CHAPTER III METHODS Chapter III reviews the methods used to conduct this research pro- ject. First, the contingent valuation (CV) method is defined and the problems associated with it are discussed. Second, application Of CV in this study is addressed as are the efforts made tO minimize bias. Third, the organization and purpose of the questionnaire are reviewed, including the differences between the telephone and personal interview forms. Fourth, the survey sample selection processes are explained for both interview types. Fifth, the administration of the questionnaires is explained. Last, the data analyses procedures are summarized. Contingent Valuation In addition to the problems associated with determining extra- market values for non-consumptive uses of wildlife, there are also methodological difficulties. Individuals' values were partitioned into mutually exclusive categories to provide a framework consistent with economic theory. The problem then became, whether individuals' values could be accurately elicited. Many studies have used contingent valuation surveys for determining monetary values associated with extra-market goods. Brookshire and 13 14 Crocker (1981) provide a concise summary Of the diverse studies under- taken. Studies using CV for examining wildlife values have been lim- ited primarily to economic values associated with hunting (Bishop and Heberlein 1979, Brookshire et al. 1982). Brookshire and Crocker (1981) point out that the key to CV is the establishment Of a hypothetical market for the good or goods being exam- ined. They go on to outline a three step procedure: (a) (C) The non-market commodity is described in quantity, qual- ity, location, and time dimensions. Various types of supplementary information including maps and photographs are introduced when appropriate. The rules of operation of the hypothetical market are established. Then a representation of the available quantity Of the environmental good is perturbed and the respondent is asked to state willingness-to-pay or required compensation, or the activity substitutions and expenditure adjustments he would make. Both a status quo quantity of the good and price are explicitly stated by the interviewer prior to any respondent statements. The first is a direct approach, while the second pro- vides information for using the indirect techniques com- monly employed with data on actual Observed behavior. The market rules of operation, bidding vehicles, and status quo prices and quantities may differ across respondents. Each respondent is presented a status quo price and/or quantity Of the non-marketed good: the price and/or quantity Of the good is then altered by the interviewer until a combination is reached to which the respondent is indifferent. Similarly, Randall et al. (1983) emphasize the structured, well-defined situation posed to respondents in CV surveys. 15 Despite the wide use of CV for valuing natural resources, doubts about the accuracy have been voiced, as well as concerns about biases encountered. Maler (1974) questioned the use Of bids as a way to deter- mine the amount individuals would be willing to pay for environmental services. More recently, Bishop et al. (1983) found by comparing vari- ous value methods that CV mechanisms may distort individuals' true wil- lingness to pay and that willingness to pay may underestimate value, while willingness to accept payment may overestimate value. Further, concerns about potential biases have also been examined. Several types of bias have been mentioned, primarily, strategic bias, hypothetical bias, instrument bias and information bias. Strategic bias can be defined as the error caused by the respondent not revealing his/her true preferences, thereby influencing the valua- tion results. This failure to reveal his/her true preferences may be based on the respondents' assumption that it is in his/her best interest not to be truthful. An example Of strategic bias would be where an individual underestimates his/her value for the good in question when payment of that value is implied or requested. Several researchers have examined strategic bias (Bohm 1972, Brookshire et al. 1976, and Rowe et al. 1980). Their results indicate that strategic bias can be countered by the design of the questionnaire. Hypothetical bias can be defined as error caused by presenting the respondent with a hypothetical situation and asking him/her to place a value on the goods in question, knowing payment will not be required. The problem of hypothetical bias has been considered by several researchers (Brookshire et al. 1976, Rowe et al. 1980, Thayer 1981, and Schulze et al. 1981). Their work indicates that this form Of bias may 16 be countered by validation Of the results. In addition, the work by BishOp et al. (1983) suggest that the differences between individuals' willingness to pay and willingness to sell may be due to the problem of hypothetical bias. Instrument bias can be defined as error caused by the structure of the survey instrument itself. Two primary types of instrument bias may be encountered, starting point bias and payment bias. Other biases caused by the structure of the instrument may exist as well. It has been suggested that the starting point of the bidding pro- cess may influence the respondent's valuations, Rowe et al. (1980) and Schulze et al. (1981) state that there are primarily two types Of start- ing point bias. First, the starting point itself may imply value or the lack of value to the respondent and may therefore influence his/her valuations. Second, depending upon the value increments chosen for the bidding game, the respondent may tire of the repetitive questioning and may give a value just to stop the process. In another study by Brookshire et al. (1977), however, the results indicate that no statist- ically significant starting point bias existed in their study. Another type of instrument bias is payment bias. The respondent's perceived acceptability Of the method of payment may effect his/her valuations. Brookshire et al. (1980) rejected the hypotheses that valuations were affected by the method of payment. They did, however, find that respondents were more likely to refuse to bid when one of the two payment forms specified was used. In addition, they received nega- tive feedback about that payment form. The results of another study by Brookshire et al. (1977) were somewhat inconclusive on the issue of pay- ment bias due to the small sample size of many of the cases tested. 17 Information bias can be defined as the potential influence of the information the interviewer gives the respondent which may affect his/her valuations. Rowe et al. (1980) suggest that information bias may have a significant influence on bids depending upon the measure of consumer surplus being examined. Additionally, the respondent's answer will be biased if he/she does not fully understand what is being asked. Application of Contingent Valuation In trying to determine extra-market values for non-consumptive uses of wildlife, a somewhat modified version of Brookshire and Crocker's contingent valuation method, as outlined earlier, was used. First, with regard to (a) (on page 14), the non-market commodity was given (either one or all four species considered, depending upon the survey type) as well as time dimensions (present and future). In general terms, the quantity was specified to the personal interview respondents by inform- ing them that two of the species were common in Michigan and two were uncommon. Telephone respondents were not told anything about the rela- tive abundance of the species they were asked about. The quantity and location were not specified because the respondents' values for the species at that point in time were the desired valuations. The purpose. of the questionnaire process was not to educate or increase the respon- dents awareness either before Or during the administration of the ques- tionnaire. In addition, visual aids were used during the personal interviews to explain the value measures. Second, with regard to (b) (on page 14), the iterative bidding technique was explained to respondents as were the potential forms of payment. The status quo quantity was implied to each respondent as the (amount currently available for his/her enjoyment. Although a numerical 18 amount was not explicitly specified the respondent had the choice of zero levels of the resource or the amount currently available. Each respondent was randomly assigned a status quo price (bid starting point) prior to the administration Of the questionnaire. Finally, with regard to (c) (on page 14), each respondent was given the quantity (implied) and a price. Through iterative bidding he/she was asked for the highest amount he/she would be willing to pay for various situations related to the value measures specified. Efforts were made through the design Of the study to minimize the biases that have concerned other researchers. Careful attention was given to the design and wording of the questionnaires to reduce the affects Of bias associated with the instrument itself and the adminis- _ tration of the instrument. Strategic bias. The questionnaires were designed so that there was little or no incentive for the respondents not to reveal their true valuations. Respondents were not told that they would be asked to pay the average bid of all respondents, as this could provide incentive to underestimate bids. Respondents also knew that attempts would not be made to collect the bid amount. Therefore, overestimation was possible, but there would be no advantage in doing so. Hypothetical bias. Time constraints prevented using an elaborate “realistic" hypothetical situation for the respondents to react to. Consequently, when feasible, respondents' real life experiences were relied on. First, respondents were asked about past experiences with the species to stimulate recall about the interactions they have had. These past experiences were then used to classify respondents into "users“ and "nonusers" Of the species, thereby providing a reference 19 point for the valuations. In situations where the respondent had no past experiences with the species, his/her knowledge about the species was used as a reference point. Instrument bias. Both types of instrument bias were considered in the study design. In the original design, each respondent would be ran- domly assigned a bid starting point ranging from $50.00 to $300.00, at $50.00 increments. Preliminary analysis Of median values indicated that the starting points were too high (Table 1). As a result, the bid starting point of $50.00 was used for the personal interviews. In addition, some telephone interview respondents showed Obvious irritation with the high bid starting points. Therefore, efforts were made to find the respondents' acceptable bid range quickly by using non-uniform intervals. (Example: If a $300.00 starting point was unac- ceptable to a respondent then $100.00 was tried, then perhaps $50.00) It was considered more important to find the respondents' acceptable range quickly than it was to use uniform bidding intervals in an effort ' to minimize time on the phone and the possibility of the respondent giv- ing the answer to "get on with it". In an effort to counter payment bias the form of payment was pur-- posely made unclear. Examples of ways the respondents currently pay for things was presented, including voluntary contributions, increased taxes paid to the state, and user fees. It was expected that by giving respondents a list of possible payment forms that they would find at least one Of them acceptable and therefore, would not let the form Of payment influence their valuations. 20 Table 1.

Respondents were not told about the species appearance, distribution or life history. It was felt that this type of information could create bias that would not exist in the general popu- lation unless everyone had the opportunity to receive the same informa- tion. Personal interview respondents were told that two common and two uncommon species were considered, and this may have influenced bids for the uncommon species, especially the lake sturgeon. Questionnaire Design The study design for this project involved two types of interviews: telephone and personal. It was intended that the same basic information would be collected by both interviews. One notable exception was that the personal interview questionnaire asked respondents' values for all four species, while the telephone interviews questionnaire asked values for only one species (randomly selected from the four species con- sidered). Therefore, a modified version of the personal interview ques- tionnaire was used for the telephone interview. The result was one per- sonal interview questionnaire (See Appendix A1) and two telephone ques- tionnaires - one for birds and one for fish (See Appendix 81 and B2). A (These two telephone questionnaires will, however, be referred to as "the" telephone interview questionnaires.) This was done to aid the telephone interviewers in asking the appropriate questions for each species. Both the personal and telephone questionnaires contained the same major sections. They were: A - Recreation Participation, B - Past Experiences, C - Value Measures, and D - Demographic Information. Sec- tions A and D were exactly the same in both questionnaires. In the 22 telephone interview questionnaires, sections B and C contained questions about only birds or fish. The goal in developing the questionnaires was to make it as easy as possible for the respondents to answer the questions posed. The ques- tionnaires began with questions that required the least amount of thought (Section A), worked toward questions that required the most thought (Sections B and C), and ended with easier questions (Section D). A broad-to-narrow questioning strategy was employed in Sections A through C. Broad natural resource questions were asked in Section A, while specific species value questions were asked in Section c. This was done so each section would build on the next and to help get the respondents in the frame of mind to answer the value questions. The most personal and perhaps the most Objectionable questions were asked last. This was done in an effort to minimize respondents' termi- nation Of the interview as they had already invested time in answering the earlier questions. The purpose of Section A - Recreation Participation - was to get a general idea Of respondents interest and participation in natural resource related activities. Kellert (1979) has shown that individuals' perceptions about and feelings toward wildlife are affected by their knowledge of the species and their interest in outdoor activities. The intent of Section B - Past Experiences - was to determine the extent of interaction the respondent had with the species in question. The purpose of this was two-fold; first, to get the respondent thinking about the species and second, to determine if he/she was a user or non- user of the species. The questions he/she was asked in Section C depended on his/her response from Section B. 23 The first part of Section C - Value Measures - was used to learn the importance to the respondents of having the species available under the condition outlined. Personal interview respondents were given a card explaining three types of values - use value, option price and existence value. The three values were explained verbally to the tele- phone interview respondents, then they were asked if they understood the concepts. This was the first time during the interview that respondents were asked to think about their values for the species. It is important to note that most respondents had never thought about the value of non- consumptive uses of wildlife. This section was not critical to the analysis, but was a tool to help the respondent organize his/her think- ing prior to the value measures. In the second part of Section C, the iterative bidding technique was used to determine the respondents' values on each measure. This was done to make the respondent think about each monetary possibility and judge whether or not he/she would be willing to pay that price. After the respondent's maximum bid point was reached, he/she was asked, "Is ____the most you would be willing to pay..?", to verify the respondent's previous valuation in an attempt to ensure that they were satisfied with their response. The last question in Section C asked respondents to assess the accuracy of their responses to the value questions. This was included to determine the respondent's feelings about their values in hopes of providing an indication of the accuracy (via respondent self evaluation) of the responses. 24 Standard demographic questions were asked of all respondents. Visual aids were used in the personal interviews for age, educational level and income level. Section D was included to understand the nature of the sample populations and to determine what relationships exist between demographic variables and certain questionnaire responses. Sample Selection Telephone Interviews Two locations were chosen for telephone surveys, Ingham county and Bay county. Ingham County was chosen because of the lower cost associ- ated with Obtaining telephone interviews. Telephone survey interviews were conducted from October 1982 through March 1983. Most of the calls made were toll calls. Bay county was chosen as a comparison area for the results of the Ingham county interviews. The population charac- teristics of Bay county are similar to those of Ingham county which allowed the effect on values of proximity to a Great Lake to be exam- ined. A total of at least 120 usable telephone interviews were needed from Ingham county and 30 from Bay county for sufficient comparisons to be made. The population distributions for Ingham and Bay counties were obtained from 1980 Census data. Proportional random sampling was used in both counties (See Appendices C1 and CZ). Phone numbers were taken from 1982 telephone directories for each area. The actual selection of residential telephone numbers was a multi- step process. First, the number of phone numbers per page was estimated by randomly selecting a few pages, counting the phone numbers per page and averaging them. Second, the number of business phone numbers per page was estimated by randomly selecting a few pages, counting the 25 number of business phone numbers and averaging them. Third, the average number of business numbers per page was subtracted from the average number of phone numbers per page, giving the average number of residen- tial phone numbers per page. Fourth, the total number of pages for any one location were counted and multiplied by the average number of residential phone numbers per page, giving the total number of residen- tial phone numbers for that location. Fifth, the total number of residential phone numbers per location was divided by the estimated number needed (as determined from the census data) to get evenly spaced selections. Sixth, a ruler was used to measure the distance between selections. Last, if the selection fell on a business number, the number was not used and the first residential phone number below it was selected. Measurement then continued from that point. It was estimated that 60 telephone numbers for Bay county and 240 telephone numbers for Ingham county would be needed for the pool of potential telephone respondents. Prior to the completion of the tele- phone interview phase all the numbers selected for Ingham county were used. A second round of phone numbers were chosen half way between the phone numbers chosen in the first round (they had been marked in the . phone book). Three attempts were made to contact potential respondents at each phone number. Both the day and the time of day were varied to allow for irregular work hours and other activities. It was soon discovered, how- ever, that week nights between 6:30 p.m. and 9:00 p.m. were the most successful. Some calls were made on Saturday afternoons, but these were usually successful only when the weather was poor. 26 When a potential respondent was reached, he/she was read a prepared text explaining the purpose of the call. He/she was then asked a series of questions to determine his/her interest in participating and suita- bility as a respondent. If the respondent was interested, and lived in Ingham or Bay county, and was at least 18 years of age, the interview commenced. Personal Interviews Personal interviews were conducted in Ingham county only. This location was the most practical for the researcher and minimized the time and travel required for each interview. Personal survey interviews were conducted from June through August 1983. Approximately 30 usable personal interviews were needed, which would result in a comparable sam- ple size per species to the Ingham telephone interview. Potential personal interview respondents were selected from a ran- domly generated list of Ingham county drivers license holders purchased from the Michigan Secretary of State. Using 1982 telephone directories, each name on the list was checked and matched with a phone number when possible. In cases where phones were not listed in the name provided, addresses were used to match phone numbers. The names on the list, for which phone numbers could be found, were then numbered. Possible respondents were selected using a random numbers table. Personal interviews were conducted in "waves." Fifteen potential respondents were selected at a time and letters explaining the project were sent to them (See Appendix A3). Follow-up phone calls were made a few days after the letters were sent. Again, three attempts were made to contact the individuals, as with the telephone interviews. Again, evenings were the most successful time to call. 27 When potential respondents were reached they were given the same information. First, the caller identified herself and reminded them that a letter briefly explaining the project had been sent. Second, the potential respondent was asked if they recalled receiving the letter and if they would like more information. (Almost all wanted to know more). Next, more detail about the project was provided, including (1) that their participation would entail a personal interview, (2) that the interview would take approximately 30 to 45 minutes, and (3) that the interview would be arranged at their convenience. Last, individuals were asked if they would be willing to participate. For those who were willing, an appointment for the interview was made and the respondent's address was verified. Administration of the Questionnaire Telephone Interviews The species and bid starting point were selected prior to the administration of each telephone interview. The species selection pro- cess was as follows. The name of each species was written on two separate small cards. The eight cards were placed in a plastic bag and one species card was drawn at random. The selected card was then replaced before the next selection (random sampling with replacement). The bid starting point selection process was the same as the species except there were six possible bid starting points. On average, the telephone interviews went quickly, taking less than 10 minutes each. TO minimize time on the phone and reduce the respon- dents' potential irritation with the process, the background information given to the personal interview respondents was omitted. In addition, 28 some questionnaire instructions were reduced somewhat for the telephone interviews, while others were expanded to compensate for the lack of visual aids provided during the personal interviews. Any questions regarding background information on the species or the purpose of the project were answered after the completion of the interview. ‘ Personal Interviews Each personal interview respondent was given the same introductory information immediately prior to the interview. First, he/she was given background about the project, including the funding source and what broad problems were being examined. Second, he/she was told about the survey, and the questionnaire and its design. Third, he/she was told that the interview would take between 30 and 45 minutes and that he/she must answer the questions alone. Lastly, the respondent was asked if he/she had any questions before the interview began. It was generally found that respondents were able to grasp the value measure and the bidding technique quickly. Therefore, during the course of the interview some of the instructions for repetitive ques- tions were abbreviated. The extent to which this occurred depended upon the interviewer's perceptions of the respondent's understanding. It was felt that abbreviating the instructions would not bias the respondent's valuations as much as their impatience with listening to redundant instructions would. 29 Data Analyses Survey data were analyzed using the Statistical Package for the Social Sciences (SPSS). Specific analyses included: frequency distribu- tions for all questions by survey type, comparisons of median and mean values for use, Option and existence questions by survey type and com- parisons between various mean values using t-tests. In addition, obser- vations and comments made during the interviews are also discussed. CHAPTER IV DATA ANALYSES The questionnaire data were analyzed at two levels. First, the frequency distribution for each section of each survey was analyzed. This included computation of the mean and standard deviation for the value questions. Second, the means of various sets of value questions were compared using standard t-tests. Comparisons included the mean values of: Bay and Ingham surveys, Ingham telephone and Personal sur- veys, and Nonusers and Users. Demographic Characteristics Each respondent was asked eight background questions to obtain a demographic profile in each of the three surveys (Table 2). Questions included: sex, age, marital status, education, employment status, occu- pation, residency and income. (See Appendix D for 1980 Census data for Bay and Ingham counties.) Bay Survey SEX. Nearly 52% of the Bay respondents were female and 48.3% were male. This is almost the same percentage of adult females and males found in the 1980 Census for Bay county. AGE. Twenty-four percent of the respondents were from 20-29 years of age.

EMPLOYMENT STATUS. Over 48% of the respondents were employed full-time, and 29.2% were not employed and not looking for full-time work. OCCUPATION. Eighteen percent of the respondents classified themselves as professional or technical, with 17% indicating they were sales, cler- ical or Office workers. Over 16% were students (See Appendix E). RESIDENCY. Approximately 73% of the respondents said they were urban residents and 27% were rural residents. INCOME. Nearly 24% of the respondent earned less than $10,000 annually. The second largest income groups, with 16.4% each, were $10,000 to 35 $19,999 and $20,000 to $29,999. Ingham county telephone respondents' income levels generally followed the income levels for the population of the county as defined by the 1980 Census. Personal Survey SEX. Over 53% of the personal interview respondents were female while 47% were male. This closely follows the percentages of adult females and males found in the 1980 Census for Ingham county. AGE. The two highest age groups, with 26.7% each, were 30-39 years and 50-59 years. Second, with 23.3% was 40-49 years.

Nearly 27% earned $10,000 to $19,000 annually. Personal inter- view respondents' income levels tended to be higher than those for the population of Ingham county as defined by the 1980 Census. Recreation Characteristics Respondents were asked a series of questions about their recreation activities during the 12 months prior to their survey participation. These questions were asked to get a general idea of their interest and participation in natural resource related activities. Recreation ques- tions included: various outdoor activities, membership in environmental organizations, donations of money to environmental organizations and frequency of watching wildlife related programs on television. Results of this section for each survey are found in Table 3. Bay Survey OUTDOOR ACTIVITIES. Of the 9 activities listed, nearly 83% of the respondents drove for pleasure. Next, with 72.4% was hiking, backpack- ing or walking for pleasure. Between 52% and 58% of the respondents fished, camped or went boating in the previous 12 months. ENVIRONMENTAL ORGANIZATION MEMBER. Nearly 14% of the respondents belonged to organizations whose main purpose was learning about and enjoying natural resources. Only 30% belonged to hunting or fishing organizations (See Appendix F1). 37 No.ON Nm.- Nm.o~ wmzoz ameum Housmacouw>am A.uuo ..eum .CHGH: emmzmz H.0mz .ufinaauwouu H.omzv onezm No.0m Nw.oc N©.n~ chfixfin .wawfixwv wonuo No.05 Nm.~n Nm.wq wafizoumacufin wo :oaun>uomno OMHHvaz No.04 Nm.mm Nm.ee Anaauwoooea uooeuso N~.om N~.om Nm.~m ouaaaafla no“ w=3>wun Nm.mw N~.an Nq.mn owsmmoaa pom mcfixama no wcfixmmxomn .wafixfi: Nm.om Na.mq N~.Hn wafiqsao N~.eo Nm.oo No.mn wanuoaao no manuaom No.oH Nm.o~ No.am menace: mmHaH>Heo< No.os No.om N~.Hm mafiamflm mooaeao Asmuzv Acmnnzv Aamuzv magm A<20mmmm ScmozH w¢m onHu=m an oam>og coaumouoom .muaouaoamom .m OHAMH 38 Nc.om Nn.oe Nm.m No.o Nm.eq Nq.mm Nm.- Nq.m Na.mm Nm.¢m NN.- Nm.o~ A.n%\mnoa no ofiv amnmo A.n>\m on mV adamaonmmooo A.nm\oo«3u no mocov >Honmm . no>oz mz8 mmHAQAHS IUH<3 39 DONATED MONEY TO ENVIRONMENTAL ORGANIZATIONS. Slightly more than 10% of the respondents had donated money to environmental organizations (See Appendix F2). WATCH WILDLIFE PROGRAMS. .Nearly 38% of the respondents indicated they often watched wildlife related programs on television, while 34% said they watched them occasionally. Ingham Survey OUTDOOR ACTIVITIES. 0f the 9 activities listed 86% of the participants said they drove for pleasure within the previous 12 months. Second highest was hiking, backpacking or walking for pleasure, with 79.2%. Three other activities were participated in by 50% or more of the respondents: boating or canoeing; wildlife Observation or birdwatching; and fishing. ENVIRONMENTAL ORGANIZATION MEMBER. Ten percent of the respondentS' belonged to organizations whose main purpose was learning about and enjoying natural resources (See Appendix F1). DONATED MONEY TO ENVIRONMENTAL ORGANIZATIONS. Over 12% of the respon- dents donated money to environmental organizations (See Appendix F2). WATCH WILDLIFE PROGRAMS. Nearly 47% of the respondents often watched wildlife related programs on television, while 35% said they watched them occasionally. 40 Personal Survey OUTDOOR ACTIVITIES. 0f the 9 activities listed 87% of the respondents indicated they drove for pleasure within the previous 12 months. Over 83% hiked, backpacked or walked for pleasure. Two other activities were participated in by over half the respondents: wildlife observation or birdwatching (70.0%); and boating or canoeing (66.7%). ENVIRONMENTAL ORGANIZATION MEMBER. Six percent of the respondents belonged to organizations whose main purpose was learning about and enjoying natural resources, while 3.0% belong to hunting or fishing organizations (See Appendix F1). DONATED MONEY TO ENVIRONMENTAL ORGANIZATIONS. Twenty percent of the respondents donated money to environmental organizations (See Appendix F2). WATCH WILDLIFE PROGRAMS. Fifty percent of the respondents often watched wildlife related programs on television, while nearly 47% watched them occasionally. Comparisons with Hunters and Anglers State-wide According to the 1980 Survey of Hunting and Fishing for Michigan, state-wide 14.5% of the population hunts and 25.6% of the population fishes. Both Bay county and Ingham county telephone surveys included more hunters than the state average, while the Personal survey included less. All three surveys (Bay, Ingham and Personal) included more anglers than the state average. 41 Past Experiences With Species Respondents were asked a series of questions about their past experiences with the species being considered. The purpose of these- questions was to learn the extent of interaction the respondent had with the species; thereby determining if he/she was a user or nonuser; and to get the respondent to think about the species. Past experience questions for the bird species included: has he/she seen species, number of times seen, seen species in past 12 months, did he/she make a special effort to see species, number of trips in past 12 months to see species, cost of species trips, extra time taken for species trips, enhancement of trip to see species and has he/she a desire to see species in his/her lifetime. The results of the past experiences with bald eagles for each survey are found in Table 4. The results for the past experiences with gulls for each survey are found in Table 5. Past experience questions for the fish species included: has he/she fished for the species, if so how many times in the past 12 months and the average cost of each trip; has he/she gone with anyone who was fishing for the species, if so the number and cost of each trip; has he/she eaten the species; or seen it in hatcheries, aquariums or in the wild; what special efforts to see the species were made; and how much did the special trips cost. The results of the past experiences with lake trout for each survey are found in Table 6.

Accuracy of Responses to Value Questions Bay Survey» All the participants in the Bay survey felt their responses to the value questions were fairly accurate (Table 12). Ingham Survey Most of the Ingham survey participants felt their responses to the value questions were fairly accurate. In total, over 91% indicated their answers were fairly accurate (Table 12). Personal Survey All of the participants in the Personal survey felt their responses to the value questions were fairly accurate (Table 12). Species Total Value The average total value for each species was obtained by adding the average use, Option and existence bids for that species (Table 13). Results show that the Bay survey total values were consistently lower 75 than either the Ingham survey or the Personal survey. The total values for the common species, gulls and lake sturgeon, differed by $.70 and $1.30, respectively. Total values for the uncommon species varied more widely. Comparisons of Median and Mean Bids Measures of central tendency are Often used to give insight into the typicalness of a population distribution. Various measures can be used to describe what is typical including, mean, median and mode. In this research, there was the problem of eliciting extreme dollar amounts during the iterative bidding process. In an effort to compen- sate for the effects of extreme values, the median and mean bids for the value measures were compared. The median value is less influenced by extreme values than is the mean value. Therefore, the median value is the preferred measure of central tendency when extreme values exist. Bay’Survey Comparisons between the median and mean bids for the Bay survey indicate that extreme values were given for all the gull values and the; lake trout and lake sturgeon use and option values (Table 14). This concurs with the frequency data for the Bay survey found in Tables 8-11. 76 mm.How oh.¢wm oa.~ow no.non Hmcomnom on.nno oo.oon oe.new m¢.w¢~w amswaH WDA<> A¢ Aw.mam on.anm mo.¢~w o~.o~w “mm :oownaum oxmu ozone 03mg madam moawmm mMHUmmm .mmzk >o>nsm kn monowam nomm mo unam> Hones mmmno>< .mA manna Table 14.

In some cases, this is due to extreme values alone, while in other cases the influence of extreme values is increased by the overall frequency dis- tribution of the bids (Tables 8-11). Personal Survey Comparison between the median and mean bids for the Personal survey again indicate a difference between most of the values (Table 16). Again, this is due in part to extreme values alone and the compounding factor of the frequency distribution of the bids (Tables 8-11). Table 15.

Standard two tailed t tests were used to test if there were statistically significant differ- ences between these means. All calculated t values were compared to t- table values at a = .05 levels. In cases where there were no table values listed, the values were extrapolated. Telephone Survey The average bids for all value measures for the telephone surveys (Bay and Ingham) were compared (Tables 17 and 18). For all the bird species value measures, there were no statistically significant differ- ences between the mean bids. For the fish species value measures, all but one showed no statistically significant difference between the mean bids. A statistically significant difference existed between the lake sturgeon existence bids for the Bay and Ingham surveys. 82 Table 17.

To achieve this, the mean bids for the two survey types would need to show no statistically significant difference between the two sets of means. Therefore, the average bids for all value measures for the two surveys conducted in Ingham county were compared (Tables 19 and 20). For all the bird species value measures, there were no statisti- cally significant differences between the mean bids. For the fish species, all but one showed no statistically significant difference between the mean bids. A statistically significant differences was found between the lake sturgeon use bids for the Ingham and Personal surveys. This difference may be more a result of the small sample of Ingham county sturgeon users (N=2) surveyed, rather than true mean popu- lation differences. 85 Table 19.

Talhelm (personal communication) has estimated this sport fishing value to be $40 to $45 per day, in 1983 dollars. This value can be compared with an estimated per day use value obtained from survey respondent lake trout anglers. For the purpose of this comparison, the use values for respondents who had fished for lake trout in the previous year were summed and divided by the anglers' total number of lake trout angling days in the previous year. The resulting value was a rough estimate of the value of lake trout fishing per day to 91 respondents. It is important to note that this value may be somewhat inflated because the anglers' use value may have included value for uses other than fishing, such as eating. The estimated lake trout sport fishing value per day, for each sur- vey was: Bay - $37.50, Ingham - $6.21 and Personal - $23.50. Comparing these values with $40 - 45/day, CV appears to have underestimated wil- lingness to pay. This underestimation is consistent with the results of a similar comparison of travel cost and CV methods by Bishop and Heberlein (1979). Observations of and Commentsgby Respondents Respondents' actions and comments during the interview process add insight into their reactions and responses to various questions. There- fore, observations of and comments by the respondents are briefly dis- cussed. Telephone Interview Respondents Most of the telephone interview respondents were relatively patient with the interviewer while the questions were being asked. This was probably because the respondents were told that the interview would take 10 to 15 minutes and all were completed in less than 10 minutes. This overestimate of the time the questionnaire would take may have reduced the likelihood that the respOndent would answer inaccurately to hurry the interview along. Many of the telephone respondents were noticeably irritated with high bid starting points. Frequently the respondent would laugh or ask the interviewer if she was serious. For this reason the interviewers 92 tried to find the respondent's acceptable bid range quickly, so as not to irritate them further. Some of the respondents bid zero on the value questions. A few offered explanation including: the Michigan DNR should be taking care of this anyway; the money should come from license fees only; the money should come from trout fishermen and businesses that profit from lake trout rather than the general public; and there should be enough money in the DNR already - don't give DNR money to other programs. few respondents refused to bid at all. Reasons given included: the questions were not applicable for a single species; sea gulls were not a worthy cause and he/she didn't like the questions. he/she didn't have adequate time to think abut the money questions; and the money questions were irrelevant and he/she didn't care to respond. Personal Interview Respondents The personal interview respondents were generally friendly to and patient with the interviewer, during the interview. The respondents were told the interview would take about 45 minutes, and most were com- pleted in 30 minutes. There was little indication that the respondents tried to hurry the process along, thereby jeopardizing the accuracy of 93 their reSponses. Two notable exceptions to this were when one respon- dent had unexpected company and the other was watching a TV game show while trying to respond to the questions. The $50.00 starting point appeared to pose no problem for most of the personal interview respondents. There were, however, indications that $50.00 was still perceived as too high by a few. Some of the respondents bid zero on the value questions. Most who did so indicated that they did not value a Specific aspect of the species, such as the use of lake trout. Others felt there were enough of the species already (gulls and trout) and they didn't need to be financially supported. One respondent bid zero on all value measures for all species stating that preserving any specific species was a waste of money. After the personal interview was formally completed, respondents were asked an additional question informally. They were asked if they bid on each species separately or if their bids were influenced by their previous species bids. All personal interview respondents said they bid on each species separately and did not allow their previous bids to 1 influence their subsequent bids. CHAPTER V SUMMARY, CONCLUSIONS AND RECOMMENDATIONS Chapter V includes a summary of the key findings of this study, conclusions based on these findings and recommendations for further study and research. M Bay Survey The typical Bay telephone respondent was, 20-29 years old, married, with a high school education and a household income of $30,000 to $39,999 annually. The sample of Bay county respondents was similar to the general population of the county with a regard to their age and sex. Respondents did have somewhat higher levels of education and income than the general population. Most Bay county respondents were classified as nonusers of bald eagles and lake sturgeon, and as users of gulls and lake trout. The average option and existence bids were higher for bald eagles than for gulls, and higher for lake trout than for lake sturgeon. The average total bids for each species ranged from $17.87 for lake sturgeon to $71.16 for lake trout. All Bay respondents felt their answers to the money questions were fairly accurate. 94 95 Ingham Survey The typical Ingham telephone respondent was male or female, 20-29 years old, married, with some college education and an annual household income of less than $10,000. The sample of Ingham county telephone respondents was similar to the general adult pOpulation of the county with regard to sex, age and income levels. Respondents did have some- what higher levels of education than the general population. Most Ingham respondents were classified as nonusers of bald eagles and lake sturgeon, and as users of gulls and lake trout. The average use and Option bid was higher for lake trout than for lake sturgeon, while the average existence bid was higher for lake sturgeon than for lake trout. The average total bids for each species ranged from $41.46 for gulls to $148.43 for bald eagles. Most Ingham respondents felt their answers to the money questions were fairly accurate. Personal Survey The typical Personal interview respondent was male or female, 40-49 years Old, married, with some college education and an annual household income of $20,000 - $29,999. The sample of Personal interview respon- , dents from Ingham county was similar to the general population of the county with regard to sex. Respondents tended to be slightly older than the general population, and had higher levels of education and income. Most Personal interview respondents were classified as nonusers of bald eagles and lake sturgeon, and as users of gulls and lake trout. ~ The average use, Option and existence bids were higher for bald eagles than for gulls, and higher for lake trout than for lake sturgeon. The average total bids for each species ranged from $41.95 for sturgeon to 96 $95.67 for bald eagles. All Personal interview respondents felt their answers to the money questions were fairly accurate. Comparison of Mean Bids Three sets of mean bids were compared to test for statistical differences between means. They were comparisons between: Bay and Ing- ham surveys, Ingham and Personal surveys, and Nonusers and Users. A statistically significant difference was found (at a = .05) in only two of the 38 comparisons made: the lake sturgeon existence bids for Bay and Ingham surveys, and the lake sturgeon use bids for Ingham and Personal surveys. Differences between the mean bids in both cases can probably be attributed to the small sample sizes used for comparisons rather than true population differences. Review of Goals and Hypotheses At the onset of the research several goals were identified and hypotheses were formed. 94412. The first goal was to determine if individuals are able to concep- tually divide their total value for a specified wildlife species into “ its' component values and assess each component separately. Respondents were able to conceptually divide their total value for a species into component values and assess each component separately. There is some question, however, if they perceived each component as was intended. The use value was intended to measure the value of the respondents' present ggdufgtgge use of the species. The option price question was intended to measure Option value - the value respondents' placed on the guarantee of the future option of use, not the value of future use 97 itself. In reviewing the value measure questions it was felt that the difference between the use value and option price was not clearly made. It appears that the use value question may have elicited present use values only and that future use values were included in the option price question. Therefore, the option price values may not accurately measure the amount respondents are willing to pay for the 923129 alone of future use of the species. The second goal was to determine the magnitudes of the components as an approximation of their relative importance. It was felt that some consistent order of values, based on the mean bids for each value, might be found. If so, this could provide insight into the importance of the various components of total value to individuals. In comparing the mean bids for each value by species and survey type, no consistent order of values appeared. It is, however, important to point out that the magni- tudes Of the mean bids for the values were generally similar. This finding is especially relevant to the magnitude of existence values com- pared with that of use value. Conclusions regarding the relationship between the magnitudes of use and existence value to option price value are unclear because of the uncertainty about the reliability of the Option price bids, as discussed in the preceding paragraph. Speculativ- ley, the magnitude of Option price may be a small percentage of the mag- nitudes of the other two values. Goal three was to determine the approximate total value of each species and use this as an indicator of individuals' preferences between species. The approximate value for each species was identified as the average total value of the species, computed by adding the average use, Option and existence bids (See Table 13). Comparing the average total 98 values for each species by survey type shows no clear pattern of prefer- ence between species. Bald eagles were the most highly valued species by both Ingham and Personal survey respondents, while lake trout were the most highly valued species by Bay survey respondents. The responses from Bay county participants may be different than those of Ingham county participants because of the smaller sample size, or because there are more lake trout anglers near the Great Lakes. Gulls ranked last with Ingham respondents while lake sturgeon ranked last with Personal respondents (gulls were ranked a close third to sturgeon, however). The fourth goal was to examine the possibility that the relative magnitudes of the values may be related to other factors including geo- graphical location. Comparisons between Bay and Ingham.telephone survey means bids Showed no statistically significant difference between mean values. We can not conclusively accept the hypothesis that geographical location influenced respondents' average bids. Goal five was to evaluate whether respondents were able to under- stand the concepts presented, and if they felt their responses accu- rately reflected their values. For the most part, respondents were able to understand the concepts as they were presented. Some respondents, I however, did require additional clarification of the values. As men- tioned in the discussion of the first goal the concepts respondents were presented with and understood were perhaps not exactly the concepts intended to be presented. Almost all respondents indicated that they ' felt their bid responses did, in fact, accurately reflect their values. The last goal was to Offer recommendations for further research into the problem of assessing extra market values for non-consumptive 99 uses of wildlife. Recommendations are addressed in the last section of this chapter. Hypotheses The first hypothesis was that people do hold option prices and existence values for fish and wildlife resources, and these valuations differ from species to species. Respondents do hold existence values for fish and wildlife resources, and most probably have Option prices for them as well. The problem encountered in evaluating the option price bids was the uncertainty regarding what the bids elicited meas- ured. It is felt that the option price bids may have included the value of future use of the species, in addition to the amount the individual would be willing to pay to maintain the 925129 of future use. There- fore, there is not a good sense of respondents' option price or their ability to conceptualize it. Further, given the uncertainty about what was actually measured, it is difficult to assess if option prices differ significantly from species to species. The existence value component of total value does differ somewhat from species to species. The order of magnitude of the existence value bids are similar, however, for bald eagles, lake trout and lake stur- _ geon. Gull existence value bids are approximately one-half the magni- tude of the existence value bids for the other species. This is perhaps a reflection of both the abundance of gulls, as well as respondents per- ceived inability to use gulls consumptively in the future. This ability to consume the fish species may have played an important role in the formulation of respondents' existence values. The second hypothesis was that option prices for each species differ from existence values for each species. This hypothesis could 100 not be adequately examined because of the probable inaccuracy of the Option price results due to the wording of the option question in the questionnaire. The hypothesis my be testable if the Option price ques- tion could be worded clearly and time for complete explanation provided. The last hypothesis was that total use values will be higher for common species (species with low utilization costs) and will be lower for uncommon species (species with high utilization costs). For the bird species, the total value for bald eagles (uncommon species) was higher than for gulls (common species) for each survey. This indicates that this hypothesis did not hold true for the bird species. The results for the fish species are somewhat inconclusive. The total value of lake sturgeon (uncommon species) was higher than the total value of lake trout (common species) for Ingham survey respondents only. Bay and Personal survey respondents, however, valued lake trout over lake stur- geon. Conclusions There were advantages to both the telephone and personal interview survey methods. The telephone interviews allowed more information to be gathered in a short amount of time. Telephone respondents were, how- ever, less likely to ask for clarification of questions and concepts. Therefore, the data collected using the telephone interview method may be less precise than that collected by the personal interview method due to the possible increased opportunity for misunderstanding. The personal interviews were much more time intensive than the telephone interviews with regard to the amount of information gathered. This extra time taken with respondents proved to be advantageous because they appeared to ask for explanation of unclear points more readily. 101 The precision of the personal interview data may therefore be higher than that of the telephone interview data. The bid starting point did not influence the respondents' bids for the survey done in Ingham county. The static $50.00 bid for the Per- sonal survey resulted in mean bids statistically equal to the bids received from the Ingham telephone survey with the randomly selected bid starting point ranging from $50.00 to $300.00. It is, possible that $50.00 may have been considered a high bid by respondents. They may have perceived a starting point of $50.00 and $300.00 as equally unac- ceptable and therefore, their bids did not reflect any differences. A lower range of bid starting points may have had a different effect on the mean bids. Generally, there existed no statistically significant difference between mean bids by survey location for the telephone surveys. There was also, generally, no statistically significant difference between mean bids by survey type for Ingham county. In addition, there was no statistically significant difference between the mean bids of species users and nonusers. Therefore, there appears to be a high degree of reliability with the data collected. The specific values elicited through the surveys were not neces- sarily the values intended to be examined. The use values obtained probably measured respondents' annual present use values of the species. It is unlikely that respondents' annual future use values were included in this use value measurement, as was intended. This was due to the unclear wording of the use value questions. The Option price values obtained may have been a hybrid of option values and option price, as defined by Bishop (1982). These values most 102 probably represent respondents' annual future use value of the species, plus the maximum amount they would be willing to pay to maintain the Option of enjoying the species in the future or the option price. The existence values represent the maximum amount respondents would be willing to pay annually to ensure the existence of the Species without regard to their own future use or enjoyment, as they were more clearly defined than the use or option price values. Despite questions about what the values elicited actually measured, important conclusions about these types of values can be made. It has been known that the values of consumptive or non-consumptive uses of fish and wildlife resources are greater than $0. This study has shown that the values of future use and the option of future use, as well as the existence of species was found to be in the same order of magnitude as the species use value. 1 In conclusion, survey resgbndents were able to affix monetary values to non-consumptive uses of bald eagles and gulls, and to consump- tive and non-consumptive uses of lake trout and lake sturgeon. By assigning values to wildlife species respondents indicated that they would be willing to pay some amount for the use and preservation of these resources, even if they did know of the species previously. This willingness to pay for wildlife resources supports the idea that wildlife are important to most individuals in society. 103 Recommendations Resource Management Decisions As pointed out in the introduction of this paper, there are limita- tions on the practical use and application of the findings. These limi- tations, however, do not diminish the significance of the results to Great Lakes resource managment decisions. It is Shown that the average use, Option price and existence values for the four species are posi- tive, and that existence value is of similar magnitude to use value. These magnitudes of values, then can be used in resource management decisions. They especially need to be included in benefit cost ana- lyses, as this study has shown that individuals do hold extra market values for fish and wildlife resources. It is also important to note how the information gathered in this study should not be used. The monetary values should not be taken as exact, but rather as “ballpark" values. Also, the average total values calculated for each species are not additive. Each respondent was asked to consider the value for one species at a time, with all other elements of consideration being held constant. Adding the average total values therefore, would result in a gross overestimation of resource value. Lastly, the values Obtained are estimates of the average value of all individuals of the species for each adult in Ingham or Bay county. The values are not the value of each individual animal to society. For these values to be genuinely useful to Great Lakes management, it is necessary to recognize the need for institutional legitimacy of extra market values and for further research. To ensure that this information is included in resource allocation decisions, researchers need more formal interaction with the decision making process. This 104 could be achieved through legislative mandate or agency policy. In addition, further research is necessary to substantiate and expand the findings of this study, so as to provide policy makers with more clear and valid estimates of extra market values of Great Lakes fish and wildlife resources. These estimates could play a key role in future resource allocation decisions. Furthermore, studies on extra market values for consumptive and non-consumptive uses of resources for other species not related to the Great Lakes or for other regions of the country might be a considera- tion. This information could lead to a more complete understanding of the array of resource values that exist for other parts of the county, as well as for the nation. These values could then be included formally in federal resource allocation policies. Further Research The need for further research is evident if extra market values are to be consistently included in resource allocation decisions. General recommendations for further research include: - complete replication of this study to verify the mean bids and if they were truly statistically the same; - broadening the sampling areas to include other areas within the Great Lakes region; - using larger sample sizes for increased reliability of data; - insuring more equal sample sizes between sample populations if comparisons are to be made; 105 carefully choosing the survey instrument to be used based on the needs and constraints of the study. Telephone interviews allow more information to be gathered in a Shorter amount of time, while personal interviews allow for more interaction between the interviewer and the respondent; limiting telephone interviews to the valuation of one species, limiting personal interviews to the valuation of no more than four species; and explicity framing the value questions so that there is more cer- tainty of the values being measured. This is especially critical to the use and Option price values. Specific recommendations for variations on this study could include: using species other than the ones considered in this study. using more similar species, such as all birds, to see if individuals are able to differentiate between them, and then, using groups of species, such as endangered birds or small mammals to see if individuals value species of similar cir- cumstance and morphology similarly; a more complete exploration of the effects of respondents' past experiences and interests in wildlife to help determine possible predictors of individuals' resource values; 106 - a more complete exploration Of the effects of geographic location on respondents' bids, and - asking individuals' total value for a species first and then asking them to partition the total value into use, option price and existence values.

The form of payment would be either 1) voluntary contribu- tions, 2) increased taxes paid to the state, or 3) user fees, such as licenses or entry permits. In each case, the money would go directly to projects supporting each species only; not to any other kinds of projects or other species. This would be the same as thinking in terms of a voluntary organization set up just for this purpose, since we know exactly what the money would be used for. Remember, though, if people aren't willing to adequately support a program, it won't be done. {Continue on if answered yes to B3.

VALUE MEASURES: USERS (FISH) There are three (3) ways I would like you to think about your values related to lake trout/lake sturgeon. {Cl. Explanation} The first way is concerned with your present and future use of lake trout/lake sturgeon. I'd like you to think about how important enjoying lake trout/lake sturgeon is to you. C1. How important is it to you to be able to fish for and/or eat lake trout/ lake sturgeon? 1. very important 2. moderately important 3. not important at all {C2. Explanation} The second way of thinking about your-value of lake trout/lake sturgeon is like an insurance policy: guaranteeing you that lake trout/lake sturgeon will be availabe in the future. In addition to how'important enjoying lake trout/lake sturgeon is to you, ' I'd like you to consider how important a guarantee of future enjoyment of th- is worth to you. C2. In addition to the value you just gave me, how important is it to you that your future enjoyment of lake trout/lake sturgeon will be guaranteed? In other words, how important is the guarantee, by itself? 1. very important 2. moderately important 3. not important at all {C3. Explanation} Lastly, you may value lake trout/lake sturgeon by just knowing they exist, even though you may never see or enjoy them yourself. You may also gain satisfaction from knowing others may enjoy lake trout/lake sturgeon, or you may value them so they can be preserved for future generations. C3. In addition to your other values, how important is it to you just to know that lake trout/lake sturgeon will exist in the future, even though you may never enjoy them directly? 1. very important 2. moderately important 3. not important at all 145 As you probably know, we all pay for government sponsored programs and facilities through taxes and/or user fees. And, obviously, we pay for private programs and services through prices, memberships and donations. ' Now, I'd like you to think about what amount of money you.would be willing to pay each year, to ensure that the types of situations I just asked about would exist. The form of payment would be either 1) voluntary contributions, 2) increased taxes paid to the state, or 3) user fees, such as licenses or entry permits. In each case, the money would go directly to projects supporting each species only; not to any other kinds of projects or other species. This would be the same as thinking in terms of a voluntary organization set up just for this purpose, since we know exactly what the money would be used for. Remember, though, if peOple aren't willing to adequately support a program, it won't be done. {C4. Explanation} First, I'd like you to think about what your enjoyment (or fishing and eating) of lake trout/lake sturgeon is worth to you. I'm going to use a bidding process to find out what your maximum willingness to pay is. C4. would you be willing to contribute $ extra each year in voluntary contributions, higher taxes or user fees, to be able to eat and/or fish for lake trout/lake sturgeon whenever you wanted to? yes {continue bidding up by amount until get negative response} no {bid downward by amount until get positive response} 3 _______ {final amount} CS. Is $ {final amount} the most you would be willing to pay, to continue to enjoy lake trout/lake sturgeon, under present conditions? yes {move on to C6. explanation} no {repeat bidding process C4. and C5.) {66. Explanation} Now, I'd like you to think about what guaranteed future enjoyment of lake trout/ lake sturgeon is worth to you, in addition to the value you just gave me. Remember, this is like an insurance policy or a guarantee. C6. C7. 146 In addition to the amount you gave me before, would you be willing to contribute 8 extra each year in voluntary contributions, higher taxes or user fees, to ensure the gggranteed future availability of lake trout/lake sturgeon for your enjoyment? yes {continue bidding upward by amount until get negative response} no {bid downward by amount until get positive response} 3 _______{final amount} Is $ {final amount} the most you would be willing to pay, to guaran- tee the future availability of lake trout/lake sturgeon for your enjoyment? yes {move on to C8. explanation} no {repeat bidding process C6. and C7.} {C8. Explanation} Lastly, I'd like you to think about what lake trout/lake sturgeon are worth to you even though you may never enjoy them in the future, or what they are worth to you to preserve for others or future generations to enjoy. C8. C9. C10. In addition to the amount you gave me before, would you be willing to contribute 3 extra each year in voluntary contributions, higher taxes or user fees, to know that lake trout/lake sturgeon will exist in the future even if you were never to enjoy them directly? yes {continue bidding up by amount until get negative response} no {continue downward by amount until get positive response} $________{final amount} Is 3 {final amount} the most you.would be willing to pay to assure their existence under present conditions? yes no {repeat bidding process C8. and C9.} How accurate do you feel your responses were to the money questions? 1. fairly accurate 2. wild guesses 147 C. VALUE MEASURES: NON-USERS (FISH) There are two (2) ways I would like you to think about your values related to lake trout/lake sturgeon. {Cl. Explanation} One way of valuing lake trout/lake sturgeon is similar to an insurance policy: assuring you that they will be available in the future. You are not presently fishing for or eating lake trout/lake sturgeon, but you may want to do so in the future. Now, I'd like you to think about how important it is to you to know lake trout/ lake sturgeon will be ggeranteed to exist for your possible use and enjoyment in the future. Cl. How important is it to you that lake trout/lake sturgeon will be guaranteed available in the future for you to possibly fish for or for eating? 1. very important 2. moderately important 3. not important at all {62. Explanation} Another way you may value lake trout/lake sturgeon by just knowing they exist, even though you may never see or enjoy them yourself. You may also gain satisfaction from knowing others may enjoy lake trout/lake sturgeon, or you may value then so they can be preserved for future generations. C2. In addition to the value you just gave me, how important isit to you just to know that lake trout/lake sturgeon-will exist in the future, even though you may never enjoy them directly? 1. very important 2. moderately important 3. not important at all As you probably know, we all pay for government sponsored programs and facilities through taxes and/or user fees. And, obviously, we pay for private programs and services through prices, memberships and donations. Now, I'd like you to think about what amount of money you would be willing to pay each year, to ensure that the types of situations I just asked about would exist. The form of payment would be either 1) voluntary contributions, 2) increased ' 148 taxes paid to the state, or 3) user fees, such as license or entry permits. In each case, the money would go directly to projects supporting each species only; not to any other kinds of proejcts or other species. This would be the same as thinking in terms of a voluntary organization set up just for this purpose, since we know exactly what the money would be used for. Remember, though, if people aren’t willing to adequately support a program, it won't be done. {C3. Explanation} I'd like you to think about what your guaranteed future enjoyment of lake trout/lake sturgeon is worth to you. Remember, this is similar to an insurance policy. I'm going to use a bidding process to find out what your maximum willingness to pay is. C3. Would you be willing to contribute $ extra each year in voluntary cotributions, higher taxes or user fees, to ensure the guaranteed future availability of lake trout/lake sturgeon for your enjoyment? yes {continue bidding up by amount until get negative response} ' no {bid downward by amount until get positive response} $_______ {final amount} C4. Is 8 {final amount} the most you.would be willing to pay to guarantee the future availability of lake trout/lake sturgeon for your future enjoyment? yes {move on to C5. explanation} no {repeat bidding process C3. and C4.} {CS . Explanation} Lastly, I'd like you to think about what lake trout/lake sturgeon are worth to you even though you may never enjoy them in the future, or what they are worth to you to preserve for others or future generations to enjoy. C5. In addition to the amounts you gave me before, would you be willing to contribute 5 extra each year in voluntary contributions, higher taxes or user fees, to know that lake trout/lake sturgeon will exist in the future even if you were never to enjoy them directly? yes {continue bidding up by amount until get negative response} no {continue downward by amount until get postive response} 3 ______.{final amount} 149 - 10 - C6. Is $ {final amount} the most you would be willing to pay to assure their existence under present conditions? yes no {repeat bidding process C5. and 66.} C7. How accurate do you feel your responses were to the money questions? 1. fairly accurate 2. wild guesses 150 - 11 - D.
