Making Tracks—A Partnership Program That Works The "Making Tracks" partnership program was initiated in 1986 with the joint signing of a memorandum of understanding between the U.S. Forest Service (USFS) and the National Wild Turkey Federation (NWTF). In 1997 alone, through the challenge cost share program, 89 projects were funded for $746,000 in 26 states. The amount of NWTF money available for partnership projects is growing at 20% per year.

Shooting Sports Events: Introducing Youth to Recreational Shooting Participants of youth shooting sports events held at the Chaparral Wildlife Management Area in southern Texas reflected the racial makeup of the region including a high percentage of Hispanics in attendance. Thirteen percent of participants indicated that they had never fired a gun prior to attendance of these events. Of those who had shot in the past, 61% did not currently participate in shooting activities other than hunting while 70% indicated that they hunt. Donald C. Ruthven III, David R. Synatzske, William G. Sheguit, James R Gallagher

Communicating a Pro-hunting Message: Pitfalls to Avoid The key to communicating a pro-hunting message is knowing what not to say and what not to do. This paper outlines 12 of the most common mistakes made when trying to communicate a pro-hunting message in a debate with someone staunchly opposed to hunting or in an interview with a reporter. With practice, each pitfall is easily avoidable. The necessary first step to avoiding them, however, is to be aware of them.

Great challenges face wildlife and fish conservation in North America. Fundamental changes that are moving rapidly through our society are mirrored to a certain extent by a virtual epidemic of reorganizations within conservation agencies continentwide. These attempts appear too often as cosmetic alterations that do not deal with the fundamental problems, and despite our good intentions, we have not been able to reduce sufficiently the distance between challenge and response.

Wildlife Agencies Perspectives of Conservation Leadership The development of the conservation movement in the United States and particularly the role of the state fish and wildlife agencies is one of the greatest conservation statements in world history. During the 20th century, our leaders have shown great foresight and vision in stewarding our country's fish and wildlife resources. It would be easy to say we are solid, we have the track record to prove our mettle—to accept the "do nothing alternative"—the business-as-usual approach. It is, ironically, our stellar record that today may be our biggest liability.

Hunters' Perspectives about Conservation Leadership In this paper, I address 2 main questions. First, what do hunters expect in terms of conservation leadership? Second, to whom do hunters look for conservation leadership? Various hunters think about leadership in different ways. All hunters think of conservation leadership in terms of making sure they can continue to do whatever it is that they absolutely need to do to think of themselves as hunters—not to go hunting, but to be hunters.

Private Organization Perspectives about Conservation Leadership The National Wild Turkey Federation was founded 25 years ago and has now grown to 150,000 members. Our mission is to conserve the wild turkey and preserve the turkey hunting tradition. The NWTF leadership is comprised of chapter volunteers and technical committee representatives from each state wildlife agency working together and coordinated by NWTF staff. The NWTF has developed a close working relationship with government wildlife agencies thanks, in part, to our successful Super Fund program which raises money through our banquets and funnels these dollars to conservation projects.

Clearly there is a recognized need for leadership in conservation. One of the great challenges facing our professional agencies and conservation groups is to decide who comprises the constituency we seek to lead. In short, what is our constituency? In many jurisdictions only a fraction of the public is even aware that a specific state agency for wildlife conservation exists. Even a large majority of hunters, long recognized as perhaps the constituency, do not look to professional agencies for leadership . . . at least not with respect to issues dealing specifically with hunting.

Enforcement of Alcohol and Drug Laws on Natural Resource Users in Georgia Conservation rangers are increasingly coming into contact with violations involving alcohol and drugs. Arrests for hunting or operating a vessel while under the influence of alcohol and/or drugs have become priorities for enforcement efforts. Arrests are also being made for other alcohol and drug violations on Department-controlled properties such as parks, public fishing areas and wildlife management areas as well as other properties. Increased training to detect these activities has produced very good results.

Illegal Turkey Hunting in Mississippi Wild turkey (Meleagris gallopavo) hunting has gained popularity as turkey populations have risen. Consequently, there is a greater chance that illegal turkey hunting will impact turkey populations. Our objectives were to determine the extent of illegal turkey hunting in Mississippi and identify potential violators. We conducted a mail survey of turkey hunters (N = 4,026) who hunted in Mississippi during the 1994 spring gobbler-only season. A response rate of 55% was obtained. Logistic regression analysis was used to predict the probability of a hunter violating a regulation. John T. Forbes, R. Gregory Dunaway, George A. Hurst, Bruce D. Leopold

Patrol Rifle Application and Training for Wildlife Enforcement Officers Wildlife enforcement trainers must be constantly on the lookout for better equipment for enforcement personnel and more effective methods of training individuals in the use of that equipment. For the past 15 years, the Law Enforcement Division of the Texas Parks and Wildlife Department has issued to its officers the patrol rifle, a piece of equipment which has only recently received serious national consideration as a viable alternative to more traditional weapons in the law enforcement defense arsenal.

An Assessment of Game Warden Personnel Needs in Texas The goal of this study was to assess the law enforcement needs of the Texas Parks and Wildlife Department. Data were obtained from several state agencies and a mail-out survey to Texas game wardens. Game wardens (N = 397) and their captains (N = 33) returned 685 of 690 mailed questionnaires (99% response rate). All 254 counties were represented. A regression model explained 78% of the total variation in the distribution of game wardens and estimated a statewide excess of 16 game wardens. In contrast, the game wardens indicated that 160 more game wardens were needed. Clark E. Adams, John K. Thomas, Jim Robertson

Electrofishing Catch of Largemouth Bass: Spatiotemporal Variation and Relation to Angler Catch I examined spring and fall electrofishing catch rates of largemouth bass (Micropterus salmoides) in 12 Texas reservoirs from 1986 to 1992 to assess the relative importance of spatial and temporal variation and to evaluate the relation between electrofishing catch rates and future angler catch. East Texas reservoirs were characterized by relatively greater temporal (i.e., annual) variation in electrofishing catch rates, whereas west Texas reservoirs tended to exhibit greater spatial variation. Reservoirs in east Texas shared a common temporal pattern in electrofishing catch rates.

Habitat use and movements associated with changes in dissolved oxygen (DO) levels and hydrology for 20 radio-tagged largemouth bass {Micropterus salmoides) were studied in the Kissimmee River, Florida, in 1992 and 1993. River channel littoral vegetation, smartweed (Polygonum hydropiperoides) and spatterdock {Nuphar luteum), were habitat types bass most commonly used. Bass maintained home areas in remnant channels and the C-38 canal that had DO >2 ppm throughout the year. J. Beacham Furse, L. J. Davis, L. A. Bull

Index of Biotic Integrity Applied to a Flow-regulated River System We developed a modified index of biotic integrity (IBI) for the Tallapoosa River system based on small-bodied fishes. The modified IBI comprised 9 metrics in 4 categories: (1) species richness and composition, (2) indicator species, (3) trophic function, and (4) abundance. We used distribution records and collection data from 1990-1995 to derive expected values for metrics. The IBI was most sensitive to changes in percentage of insectivorous cyprinids, percentage of intolerant species, fish abundance, and number of darter species, and least sensitive to total species richness.

Using an Index of Biotic Integrity to Assess Gold Mine Impacts on Streams A fish community index of biotic integrity (IBI) was used to compare 6 streams with minor anthropogenic impacts to 3 streams receiving source and non-point source effluents from gold mine operations in the Piedmont of South Carolina. IBI ratings for streams receiving gold mine effluent ranged from very poor to marginally fair, whereas those for the remaining 6 streams ranged from fair to good. The stream selected as a “candidate” reference stream rated consistently good, establishing a potential baseline for attainable conditions for the ecoregion.

Selection of Thermal Refuges by Striped Bass in a Gulf of Mexico Coastal River We located 22 potential striped bass (Morone saxatilis) thermal refuges created by groundwater inflows along the Flint River in southwestern Georgia. Line transect counts made by SCUBA divers June-October 1990 were used to develop striped bass abundance indices for 8 of the springs. Abundance differed among springs and was positively correlated with potassium concentration and distance upriver and negatively correlated with pH and dissolved oxygen concentration. Groundwater feeding the springs flows through conduits created by the dissolution of underlying limestone. Gary N. Weeks, Michael J. Van Den Avyle

Inter-river Migration of Striped Bass in Western Kentucky Fifteen radio-tagged striped bass (Morone saxatilis) were tracked to determine seasonal, inter-river distribution patterns, and habitat use in the vicinity of the Ohio, Tennessee, Cumberland, and Mississippi rivers from November 1992 to November 1993. All 4 river systems were used by study fish during 1 or more seasons. Two fish inhabited only 1 river during the entire survey, while 13 fish used up to 3 river systems. Inter-river movement occurred primarily during November-December (36%) and April-May (58%), which coincided with highest movement periods.

Distribution and Population Attributes of Gulf Sturgeon in the Lower Pearl River System, Louisiana Seven reaches of the lower Pearl River system were sampled with bottom set gill nets from 1992 through 1995. One hundred fifty-eight Gulf sturgeon (Acipenser oxyrinchus desotoi) were captured in 3 reaches. Mean fork length (FL) was 734 mm, and weight (W, g) to length (FL, mm) relation was: W = 1.786 x lO^CFL)3204. Mean weight loss during summer was 1.9 g/day. Ninety-two percent of Gulf sturgeon were captured in the West Middle River reach which is comprised of deep holes and little current. James V. Morrow, Jr., K. J. Killgore, J. P. Kirk, H. E. Rogillio

Summer Habitat Selection of Striped Bass in Lake Norman Lake Norman is a 13,516-ha reservoir frequently devoid in late summer of the cool, well-oxygenated water preferred by mature striped bass {Morone saxatilis). Large summer striped bass kills, however, are rare. The objective of this study was to determine the summer temperature and dissolved oxygen (DO) levels in habitat used by striped bass in Lake Norman. We tagged 48 striped bass (2.2-7.8 kg) with temperaturesensing radio tags (40-50 MHz) during spring 1992 and 1993. Tag frequency, tag temperature, location, and a water column temperature/DO profile were recorded for each tag encounter. Scott L. Van Horn, J. R. Finke, D. Degan

A 3-year study was initiated in 1992 to characterize the St. Johns River freshwater commercial striped mullet (Mugil cephalus) gill net fishery and estimate bycatch. Each year in fresh water, an estimated 137 fishers using 84 boats fished 1,554 days and harvested 233,109 kg of striped mullet. Approximately 86% of the fishers used the strike technique exclusively, while 14% used both strike and set-net techniques. Striped mullet comprised 99% of the total catch by number. The average annual freshwater game fish bycatch ranged from 86 to 274 fish (< 1 % by number). Marty M. Hale, R. J. Schluler, Jr., J. E. Crumpton

Field Trials to Determine the Efficacy of Human Chorionic Gonadotropin for Spawning Walleye Human chorionic gonadotropin (HCG) is often used to induce spawning of fish. However, the U.S. Food and Drug Administration (FDA) has not approved HCG for use in fish because they claim additional efficacy data are required. Efficacy of HCG for spawning walleye (Stizostedion vitreum), was evaluated at 3 hatcheries for 3 years. During the 1993-1995 spawning seasons, 17.5% (54 of 308) of female walleyes spawned after a single injection of HCG. Of 253 females receiving a second injection, 92.1 % spawned for an overall spawning success of 93.2%.

Shortnose Sturgeon Stocking Success in the Savannah River During 1984-1992, adult shortnose sturgeon (Acipenser brevirostrum) from the Savannah River were spawned and their offspring reared to various sizes prior to release in this river as part of a stock enhancement program. A total of 79,270 untagged and 18,213 tagged fish were released at various sites from river kilometer (rkm) 54 to 273. Mid and upriver stocking areas appeared to provide higher survival than downriver areas and stocking during November and December appeared more beneficial than during other months. Theodore I. J.

Use of a Nursery Pond to Establish Smallmouth Bass in Beaver Reservoir, Arkansas Production of smallmouth bass (Micropterus dolomieu) in 11 -ha Beaver Nursery Pond was estimated from 1990 to 1994 to determine numbers of fish stocked in Beaver Reservoir. In 1990, 2 rapid population sampling methods, seining a known area and SCUBA transects, were tested against a Petersen mark-and-recapture estimate. Both sampling methods provided population estimates that did not differ significantly from mark-and-recapture values, but both generated greater confidence intervals. James E. Johnson, M. G. Pardew, D. W. Bowman

Contribution of Largemouth Bass Reared in Nursery Ponds to Year Classes in Two Texas Reservoirs Genetically-marked Florida largemouth bass (Micropterus salmoides floridanus) fingerlings with rare or unique genotypes were stocked into nursery ponds at Lake Conroe (8,484 ha) and Lake Gladewater (323 ha). Following grow-out, advancedsize individuals were stocked into respective reservoirs. We measured the contribution of stocked individuals to corresponding year classes in receiving reservoirs. Largemouth bass survival in nursery ponds at the end of the grow-out period was 15.6% at Lake Conroe and 20.9% at Lake Gladewater. Michael J. Ryan, M. A. Webb, L. T.. Fries

Compensation as Mitigation for Fish and Wildlife Benefits: The Pigeon River Fund Example Poor water quality upstream of the Carolina Power and Light Company (CP&L) Walters Hydroelectric Project (WHP) resulted in establishment of a mitigation fund in lieu of immediate water releases as a condition of a new Federal Energy Regulatory Commission (FERC) license. The negotiated agreement between state management agencies and CP&L includes provisions for future instream flow releases, but until that time, CP&L will make annual payments to the Pigeon River Fund (PRF).

Characteristics of Respondents and Nonrespondents to Mail and Telephone Angler Surveys We conducted a screener telephone survey of 5,209 anglers in Mississippi to recruit participants for a statewide, 5-year, longitudinal angler survey that will administer a total of 10 surveys (waves), 2 per year. Of these 5,209 anglers, 4,393 agreed to participate in future surveys. Of these 4,393 anglers, 52% responded to a mail survey and 76% participated in a telephone survey. Twenty-four demographic and fishing preference variables were selected from the initial screener survey to compare data from respondents and nonrespondents. Gregory S. Bray, J. T. Forbes, H. L.

Anglers who fished Lake Fork Reservoir June 1994-May 1995 were intercepted during creel surveys conducted by the Texas Parks and Wildlife Department (TPWD) and asked to participate in a follow-up, self-administered mail survey. Anglers were asked questions about their fishing activity at Lake Fork, and their motivations, satisfaction, and expenditures on the trip they were intercepted. Lake Fork anglers could be characterized as high specialization anglers, indicating they had been fishing in fresh water for an average of 28 years, and fishing an average of 62 days in the previous year.

Factors Determining Quality of Oxytetracycline Marks in Fingerling Walleye Otoliths This study examined factors which can affect the quality of fluorescent oxytetracycline (OTC) marks on walleye (Stizostedion vitreum) otoliths. A 1 -time exposure to a strong ultraviolet (UV) light source, such as is done when viewing under a UV microscope, significantly decreased mean OTC mark qualities from an initial value of 2.8 (3.0 is maximum and 0.0 is no mark) to <1.0 3 months following the initial examination. Mark intensity continued to decrease over time (<0.5 after 6 months, 0.3 after 12 months). Donald R. Harrison, r. C. Heidinger

Diets and Factors Affecting Feeding Success of Age-0 Gizzard Shad Diets, food selection, and factors affecting feeding success of small (5-9 mm total length, TL), medium (10-19 mm TL), and large (20-29 mm TL) larval and early juvenile gizzard shad (Dorosoma cepedianum) were examined in 2 large Missouri reservoirs. Diets and food selection shifted from mainly copepod nauplii and cyclopoids to rotifers and phytoplankton as fish grew. Mean length of ingested zooplankton rose slightly as gizzard shad grew from the small to medium length groups and then decreased for the large length group.

Diet and Movement of Largemouth Bass and Butterfly Peacocks in La Plata Reservoir, Puerto Rico Diet and telemetry studies were conducted in La Plata Reservoir, Puerto Rico, to investigate potential interactions between largemouth bass (Micropterus salmoides) and butterfly peacocks {Cichla ocellaris). Partitioning of food resources between the 2 species was evident and consistent over several size classes. Interspecific differences were observed in home range size, diel movement, and habitat preference during telemetry studies conducted on adults for up to 250 days. Maximum activity for both species corresponded with periods of elevated food consumption. Craig G. Lilyestrom, T. N. Churchill

Stomachs of 5,818 largemouth bass (Micropterus salmoides) were examined from 10 north-central Florida lakes to determine differences in food habits of largemouth bass in lakes with abundant aquatic macrophytes (vegetated) and lakes nearly devoid of aquatic macrophytes (unvegetated). We found significant differences (P < 0.05) between stomach contents of 6 length groups of largemouth bass (range: 60-640 mm TL) from vegetated and unvegetated lakes. The 152- to 254-mm length group exhibited the greatest number of diet differences. Richard L. Cailteux, W. F. Porak, S. Crawford, L. L. Connor

Age and Growth of Trophy Largemouth Bass in Florida Otoliths from 822 trophy (>4.5 kg) largemouth bass (Micropterus salmoides) caught by anglers in Florida were obtained from taxidermists during 1987-1993. The fish were harvested from 211 different water bodies. Longevity and mean growth exceeded those reported previously in Florida. Mean age of trophy largemouth bass statewide was 9.7 years and ranged from 4.0 to 16.5 years. Mean growth averaged 0.54 kg/year with a range of 0.28-1.27 kg/year. Growth rate of trophy largemouth bass increased from north to south Florida. Steve Crawford, W. F. Porak, D. J. Renfro, R. L. Cailteux

Shorebird Migration at a Mississippi River Wastewater Treatment Plant Surveys of shorebirds from a 13-year period were compiled from the T. E. Maxson wastewater treatment plant in Memphis, Tennessee, a site bordering the Mississippi River. The data represent one of the few long-term shorebird surveys from the Mississippi River valley. Data were used to produce a migrational chronology for species both in spring and fall based on mean abundance. Least sandpipers (Calidris minutilla), pectoral sandpipers (C. melanotos), killdeer (Charadrius vociferus), and lesser yellowlegs (Tringaflavipes) were the most abundant migratory species recorded.

Response of Breeding Bird Communities to Restoration of Hardwood Bottomlands Much of the original hardwood bottomland in the Mississippi Alluvial Valley is converted to crop lands. Land management agencies began restoring hardwood bottomland because of its importance to wildlife. To provide an initial evaluation of progress toward restoration, we used point counts to compare bird communities among plantations of 0 to 4, 7 to 15, and 21 to 27 years in age with natural sawtimber stands (>50 years in age) in the southern Delta region of Mississippi in 1994 and 1995. Mean number of species per point (species richness) increased with stand age (P < 0.05).

Influence of Clearcut Age on Avian Species Composition, Abundance, and Reproductive Success Clearcutting has been reduced in frequency in national forests of Arkansas. This will affect populations of birds that require early successional forest habitat. I studied avian distribution, abundance, and reproductive success in young (i.e., 7 to 10 years post-harvest) and old (i.e., 17 to 19 years post-harvest) forest clearcuts from 1993 to 1995.

Status and Management of Endangered Bats in Arkansas Three taxa of cave bats in Arkansas are listed as endangered: the gray bat {Myotis grisescens), the Indiana bat (M. sodalis) and the Ozark big-eared bat (Corynorhinus townsendii ingens). All occur primarily in the Ozark Plateau region of the northwestern and northcentral portion of the state. Population monitoring and ecological studies of endangered bats inhabiting important hibernation, summer, and transient caves were conducted annually since 1978.

Status and Management of the Red-cockaded Woodpecker on Goethe State Forest, Florida A survey of red-cockaded woodpeckers (Picoides borealis) was conducted on Goethe State Forest, Levy County, Florida, in 1994 and 1995. Four hundred fifty-one living cavity trees, active and inactive, were located. The majority of living cavity trees (97%) were longleaf pines (Pinus palustris). Mean age of cavity trees was 123.6 years (N = 108). One hundred ninety-seven living cavity trees occurred in 26 clusters, and 25 of these clusters were active in 1995. Nestling production was confirmed in 73% and 65% of the active clusters monitored in 1994 and 1995, respectively.

Status and Distribution of Alligator Snapping Turtles in Arkansas The alligator snapping turtle (Macroclemys temminckii) occurs throughout most of the southeastern United States, but concern exists regarding possible decline in populations throughout the range of the species. Little is known about the alligator snapping turtle in Arkansas. The species was previously documented from only 20 counties in the state. We sampled 1,905 net nights with baited hoop nets and captured 445 alligator snapping turtles in 56 counties. Captures in 41 counties were new records. Brian K. Wagner, D. Urbston, D. Leek

A Comparison of Snap Traps for Evaluating Small Mammal Populations We compared rat, mouse, and museum special snap traps to determine if differences existed in capture efficiency of small mammals and whether type of trap affected indices of richness, evenness, and diversity. Small mammals were trapped in 57 streamside study areas in 1990 to 1995 in the Ouachita Mountains, Arkansas. Efficiency of mouse traps was equal to or greater than that of museum special traps in capturing all small mammal species. Roger W. Perry, P. A. Tappe, D. G. Peitz, R. E. Thill, M. A. Melchoirs, T.

Migratory Bird Depredation Permits Issued to Southeast Aquaculture Facilities This paper summarizes the issuance of federal depredation permits to commercial aquaculture facilities in the Southeast Region by the U.S. Fish and Wildlife Service from 1989 to 1996. Data were evaluated from 1,103 depredation permits issued to individual aquaculture facilities allowing lethal take of fish-eating birds. The take of 21 species of birds comprised of waders, fliers, and swimmers was permitted. In the 9 states where permits were authorized, the number of facilities receiving permits increased from 54 in 1989 to 228 in 1996. Richard A. Coon, C. Simonton, E. F. Bowers, J. L. Trapp

Ecology of Flatwoods Salamander Larvae in Breeding Ponds in Apalachicola National Forest Management of the flatwoods salamander (Ambystoma cingulatum), a species in decline throughout its range, is hindered by a lack of information on the habitat requirements of the species. Because Ambystomatids are generally philopatric, preservation of quality natal habitat is important for long-term population health and stability. Conservation of breeding sites in managed landscapes is impeded by insufficient knowledge of the habitat components required for successful larval development. Carolyn M. Sekerak, G. W. Tanner, J. G.

Characteristics and Use of Cavity Trees and Snags in Hardwood Stands A 3-year study was conducted to evaluate the availability and use of cavity trees and snags in hardwood stands regenerated using the group selection method. A survey of cavity trees and snags was completed before and after group selection harvest in 16 2.9-ha plots in the Ozark National Forest, Arkansas. Cavity trees and snags were identified to species, and the height, dbh, state of decay, and number of visible cavities recorded. We marked and measured 66 cavity trees and 126 snags with cavities, and observed the use of these cavities by wildlife. Thomas A. Nelson, M. L. Lambert

Rodent Damage to Direct Seeded Willow Oak in Louisiana Direct-seeding is no longer commonly used for reforesting bottomland hardwood habitat because of low seedling survival due in part to predation of seeds by animals. We investigated the impact of seed predation by rodents on direct seeded willow oak (Quercus phellos). Acorns of willow oak were planted at a rate of 5,982 seeds/ha on low-lying farmland in the Ouachita Wildlife Management Area, Louisiana. Larry Savage, J. Anthony, R. Buchholz
