We conducted an operational scale trial of the herbicides Sonar® (fluridone) and Rodeo® (glyphosate) to evaluate control of giant cutgrass (Zizaniopsis miliaceae) and effects on waterfowl food plants in moist-soil managed impoundments of the Altamaha Waterfowl Management Area, Darien, Georgia. Sonar and Rodeo reduced giant cutgrass frequencies both post-treatment years, although greater reduction occurred in the Rodeo-treated impoundment. Panic grass (Panicum spp.) frequency within the Rodeo- treated impoundment decreased the first year post-treatment. Donald E. Wood, K. V. Miller, D. L. Forster

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

Wood Duck Nest Cavities in Bald Cypress-Tupelo Gum Stands We studied availability of natural cavities for wood ducks (Aix sponsa) on 5 areas in 3 southeastern states in 1988-1990 because of U.S. Fish and Wildlife Service (USFWS) guidelines that called for the reduction of nest boxes on National Wildlife Refuges. Selected forested wetlands dominated by bald cypress (Taxodium distichum) or tupelo gum {Nyssa aquatica) were randomly sampled using 0.5-ha plots to estimate the density of cavities suitable for wood duck nesting.

White-tailed Deer Damage to Cotton in Alabama White-tailed deer (Odocoileus virginianus) damage to cotton (Gossypium hirsutum) was evaluated during 2 growing seasons in east-central Alabama. Deer began browsing cotton as soon as cotyledons emerged, and all plant parts were browsed during the growing season. Browsing of cotton cotyledons may kill plants and will reduce yields if it is extensive. However, browsing on cotyledons was rare in this study. Most feeding was done on cotton leaves, and occurred too late to reduce yields. Michael J. Gaylor, M. K. Causey

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.

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.

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

The Effects of Wildfires on Alligator Nests on Rockefeller Refuge Environmental factors such as flooding, drought, and predation can adversely affect alligator nesting success. No prior studies have documented the effects of wildfires on alligator nesting ecology. In July 1995, wildfires burned over 1,300 ha of alligator nesting habitat on Rockefeller Refuge in southern Louisiana. Although most alligator eggs from nests in the burned area had previously been removed by staff biologists, the burned area was searched to evaluate fire damage to remaining nests and eggs.

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

Stress Survival Tactics is a program developed as part of an officer survival in-service program for Texas Game Wardens. This paper presents a training technique that works well when dealing with the emotion-laden issue of survival stress or critical incident stress. Hormones released in a survival situation have a tremendous effect on emotions, sensory perceptions, psychomotor skills, and on one's ability to process information. Stress Survival Tactics mentally, psychologically, and physically prepares officers to train for a survival situation such as a use-of-force situation.

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 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 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 vegetation and soil study was conducted on upland disposal sites of a 4,425- ha management area in Mississippi. This area comprised disposal sites managed for northern bobwhites (Colinus virginianus). The soil and subsoil materials of these disposal areas originated from vertical cuts of geological strata up to 54 m and contained acidic overburden. Soil samples were collected at 0- to 10-cm and >10- to 20-cm depths on 35 disposal areas. Soil pH values in 0- to 10-cm depths were not related to depths to overburden. Jeanne C. Jones, D. H.

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.

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.

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

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

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).

Reproductive Characteristics of Female White-tailed Deer in Missouri We measured reproductive parameters of 2,833 female white-tailed deer (Odocoileus virginianus) collected from 1978 to 1986 and 1989 to 1993 in 3 geographical regions of Missouri. Fawn pregnancy and fetal rates were lower (P < 0.001) than those of yearling and older does. Ozark region fawns had lower fetal rates than fawns from the Glaciated Plains region; no other regional differences were found. Fetal sex ratios approached 1:1 and were not influenced by year of collection, litter size, region, or age of doe. Lonnie P. Hansen, J. Beringer, J. H. Schulz

Private Property Rights Versus the Rights of Public Domain This research project examines traditions and cultures in Florida supporting the rights of private property ownership and the harvest of game or fish, whose ownership is common to all. The conflicts which arise from these deeply held values will be identified and discussed. This study presents the results of a questionnaire administered to wildlife law enforcement officers and interviews conducted with property owners and wildlife resource users throughout the State of Florida.

Concern has arisen about effects of predation on wild turkey (Meleagris gallopavo) populations because of increases in predator abundance. We examined differences in canid (Canis spp.) and bobcat (Felis rufus) predation of adult wild turkey hens between a hardwood bottomland forest and a mixed forest in Mississippi. Daily mortality rate from canids and bobcats was higher on the hardwood bottomland forest (0.002) than on the mixed forest (0.0006), but overall daily survival rates were similar. Michael J.

Pre-incubation Habitat Use by Wild Turkey Hens in Central Mississippi Habitat use of forested landscapes by wild turkey hens (Meleagris gallopavo) during pre-incubation is poorly documented. Information is needed on how vegetative conditions resulting from forest management influence hen movements, habitat use, and reproductive success. We studied habitat relations of wild turkey hens (TV = 111) during pre-incubation in central Mississippi, 1985-1989. Groundstory composition and structure were different (P < 0.05) between areas used and not used by hens. William E. Palmer, G. A. Hurst, B. D. Leopold

Post-capture Survival of Wild Turkeys: Effects of Age, Sex and Environment Effects of capture on study animals requires thorough examination. We investigated effects of age, sex, and environmental conditions on probability of eastern wild turkey (Meleagris gallopavo silvestris) post-capture survival in central Mississippi during winter and summer capture periods, 1984-1995. Females were more likely to die from capture-induced stress than males during winter capture; adult hens were more likely to die than subadult hens during summer. Survival rates of hens captured versus those not captured in a given period were similar. Darren A. Miller, B. D. Leopold, G. A. Hurst

Population Ecology of Deer on Chickamauga Battlefield Park, Georgia Our objectives were to determine population and ecological characteristics for an unmanaged white-tailed deer (Odocoileus virginianus) herd on Chickamauga Battlefield National Military Park, Georgia, and to predict the potential for overpopulation in this herd in the future. We radio-collared 67 deer on the park over 4 years (1991-1994). An additional 295 deer were killed by vehicles on the park's roads, and 36 were collected for herd health analysis in August of each year (8-10 deer per year). The range of estimates for population density was 10-41 deer/km2. Christopher L. Tucker, R. J. Warren, K. A. K. Stromayer, C. L. Rogers

Population Characteristics and Female Denning of Black Bears in a Managed South Carolina Forest We captured 54 black bears (Ursus americanus) 91 times and equipped adult females with radio-transmitters in a managed forest in the mountains of South Carolina during the summers of 1991-1993 to determine population dynamics and female denning ecology. Ages of captured bears ranged from 1 to 10 years, averaging 3.3 + 0.3 (± 1 SE) for males and 3.7 ± 0.3 years for females. Litter size (N = 7, ˉx = 2.3), lactation rate (42.3 %), suspecting mean age at primiparity (4 years), and interbirth interval (2.2 years) were representative of a productive population and good-quality habitat.

Plant Species Composition Following Chemical and Mechanical Site Preparation We examined plant species richness and species overlap among 3 site preparation treatments (roll-chop and burn, imazapyr and burn, and imazapyr only) and a mature pine-hardwood forest during 2 years following site preparation in east-central Mississippi. Treatments were applied beginning June 1990. Inventory of plant species in 2 to 5 1.6-ha plots/treatment was completed in spring 1991 and 1992. Species richness did not differ among treatments or between treatments and pine-hardwood forest (P = 0.31). Similarity indices showed no apparent grouping among treatments. Mike Weinstein, M.

Operation Dalmatian—Covert Investigation of Dog Deer Hunting Since the 1987 closure of Texas' Type II Public Hunting Lands to the hunting of deer with dogs and a subsequent statewide prohibition of the method in 1990, the Texas Parks and Wildlife Department has received numerous complaints about small bands of East Texas hunters who continue to use the method in open defiance of the prohibition. These complaints further allege that outlaw dog deer hunters have virtually taken over public hunting lands, intimidating lawful users and ignoring the rights of adjoining private landowners.

Missouri's 1994 Conservation Monitor: Taking the Public's Pulse The Conservation Monitor was a telephone survey of 854 Missourians first conducted in 1994 by the Gallup Organization for the Missouri Department of Conservation (MDC). Objectives were to assess Missourians' opinions on the state's environment, MDC's performance, and conservation issues. Results revealed high satisfaction among Missourians with the care given their state's fish, forests, and wildlife, and more generally with the care given Missouri's natural environment.

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

Litter Size and Age of First Breeding of Florida Black Bears We estimated litter size and age of first reproduction of female black bears in Florida from the examination of 139 female reproductive tracts. Corpora lutea occurred in 81 of the tracts. The number of corpora lutea per tract, a close approximation of litter size, averaged 2.6 (range: 1-4). Most (75%) female bears bred initially when 2.5 years old, and the remainder at 3.5 years. Litter sizes and age of first breeding of female black bears in Florida are comparable to those found in other productive areas of eastern North America.

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.

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.

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.

Harvest and Hunter Activity During Florida's Special September Duck Season We estimated total harvest, hunter participation, hunter success, and age-sex composition of the wood duck (Aix sponsa) harvest during Florida's special September duck seasons, 1989-1995. We sent mail questionnaires to a sample of Florida's duck hunters to estimate harvest and hunter participation, and collected wings to estimate age-sex composition of the wood duck harvest. An average of 3,555 (SE =178) hunters participated annually, and hunter-days averaged 8,082 (SE = 473). During years when teal (Anas discors,A. Diane R. Eggeman, D. H. Brakhage

Effect of Predator Control on Reproductive Success and Hen Survival of Attwater's Prairie-chicken From 1980-1981, we tested the hypothesis that removal of potential nest predators would increase the reproductive success of the endangered Attwater's prairie-chicken (Tympanuchus cupido attwateri). Striped skunks (Mephitis mephitis, N = 74), opossums (Didelphis virginiana, N = 83), and raccoons (Procyon lotor, N = 9) were removed from a 522-ha predator removal area (PR) during February- June 1980 and 1981. Predator indices were lower (P < 0.002) and prairie-chicken nest success was higher (82% vs. 33%, P < 0.019) in the PR than a 620-ha control area (CO). Jeffrey S. Lawrence, N. J. Silvy

Effects of Hydrology on Black Bass Reproductive Success in Four Southeastern Reservoirs We surveyed the extent and availability of fisheries data from major (>200 ha) impoundments in 2 southeastern U. S. drainage basins, the Apalachicola- Chattahoochee-Flint and Alabama-Coosa-Tallapoosa, both located primarily in the states of Georgia and Alabama. Data were used to generate regression models relating fish reproductive success to hydrologic variables. Results were used to define relationships between reservoir operations and abundance of young fishes. Thomas R. Reinert, G. R.Ploskey, M. J. Van Den Avyle

Efficacy of Human Chorionic Gonadotropin for Spawning Striped Bass and White Bass Human chorionic gonadotropin (HCG) is often used to induce spawning offish. However, the U.S. Food and Drug Administration has not approved HCG for use in fish because they claim additional efficacy data are required. Efficacy of HCG for spawning striped bass (Morone saxatilis) and white bass (M. chrysops) was evaluated at 15 hatcheries in 10 states. For strip spawning of females, a single dose of HCG was effective for 90.2% of striped bass (N = 428) and 89.4% of white bass (N = 660). After strip spawning, hatching rates were 39.5% for striped bass and 26.1% for white bass. John M. Grizzle, D. Xu, W. A. Rogers

Efficiency of Archery Hunting for White-tailed Deer on Medway Plantation We conducted this study to determine efficiency of archery equipment in conjunction with tracking dogs for harvesting white-tailed deer (Odocoileus virginianus) on Medway Plantation in the Coastal Plain of South Carolina. Twentytwo experienced archers hunting from elevated stands over corn feeders shot 61 deer. A tracking dog was used whenever deer did not fall within sight of the hunter (41 of the 61 deer shot). Immediately following each hunt, the hunter completed a questionnaire to determine equipment used, shot conditions, and deer reaction. Richard T. Morton, D. C. Guynn, Jr., R. H. Hortman, J. G.

Environmental Partnerships in Habitat Conservation—Project EAGLE In spring 1994 the Florida Game and Fresh Water Fish Commission, the state agency charged with the conservation of Florida's freshwater fish and wildlife resources, recognized the need to better involve the community with solutions to current environmental problems: more specifically, community involvement in resolving with littering problems on public lands and waters. Toward that end, the Division of Law Enforcement developed Project EAGLE (Enhancing a Great Living Environment), a half-day voluntary cleanup of some of Florida's most sensitive public lands and waterways.

Evaluating Fish Habitat in a South Carolina Watershed Using GIS Fish habitat of the Edisto River Basin in South Carolina was evaluated using a geographic information system (GIS). A committee of fisheries biologists was formed to evaluate fish habitat within the Basin, and the GIS was used to compile and analyze data and generate maps to represent quality of fish habitat. United States Geological Survey (USGS) 1:24,000-scale digital line graph (DLG) hydrography data were assigned values for data on species composition, predesignated protected areas, riparian habitat, dams and impoundments, ditches and channelization, and water quality.

Evaluation of 3 Small-scale, Put-and-take Rainbow Trout Fisheries in Tennessee Percent return, survival, and harvest rates of stocked rainbow trout (Oncorhynchus mykiss) were evaluated in 3 Tennessee streams from 1991 through 1994. Harvestable-size trout were stocked 2-4 times during spring at densities of 29-188/km. Subharvestable (fingerling) trout were stocked only during fall at densities of 69-286/km. Mean annual returns ranged from 13% to 29% over the 4 years of the study and averaged 23% for all 3 streams. Returns for fall-stocked trout were negligible. Survival of spring-stocked (March-May) trout was low, ranging from 2% to 7% by July of each year. Christopher J. O'Bara, M. A. Eggleton

Evaluation of Wild Turkey Population Estimation Methods To determine effects of land use and management practices on wild turkey {Meleagris gallapovo) populations, managers need reliable, low-cost methods to estimate absolute and relative densities. Therefore, we evaluated estimation ability of 4 models using wild turkey capture data from 1986-1993 and summer bait site observations from 1990-1993 in Kemper County, Mississippi. Capture-markrecapture models performed worse (i.e., higher coefficients of variance) than capture-mark-resight models. Mike Weinstein, B. D. Leopold, G. A. Hurst

Heterogeneity in Observability of White-tailed Deer on Remington Farms Population estimates of white-tailed deer (Odocoileus virginianus) based on marking individuals and resighting them at later times require assumptions about observability that are rarely verified. Yet the accuracy of estimates depends on meeting the assumptions. At Remington Farms on the eastern shore of Maryland, we tested accuracy of mark-resight population estimates from the heterogeneity model (Mh) of the CAPTURE program against a known abundance of a marked subpopulation of the herd. We also tested the assumption of heterogeneous capture probabilities. Richard A. Lancia, M. C. Conner, B. D. Wallingford

Habitat Selection by Florida Grasshopper Sparrows in Response to Fire Minimum population estimates of Florida grasshopper sparrows (Ammodramus savannarum floridanus) made using listening stations systematically located throughout a 2,374-ha portion of the Three Lakes Wildlife Management Area (WMA) in central Florida ranged from 219-234 individuals over a 3-year period. The study area was divided into 3 units and 1 was burned each year. Grasshopper sparrow population density was related to the 3 burn regimes: <1 year post-burn, 1-2 years post-burn, and >2 years post-burn. Patrick B. Walsh, D. A. Darrow, J. G. Dyess
