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.

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

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

Effects of Early Weaning on Survival and Growth of Captive White-tailed Deer Thirty-seven white-tailed deer fawns (Odocoileus virginianus) born during summer and autumn 1993 were used to study effects of early weaning on survival and growth. Fawns at birth (date recorded) were weighed (kg), measured (cm), and tagged for identification. Fawns were randomly assigned to early weaned (treatment) or control groups at 60 days of age. Treatment animals were separated from their dams at this time, and control animals remained with their dams until 6 months of age. Both groups were fed a pelleted ration containing a medium protein level (11.6%). David F. Carroll, M. K. Causey

Effects of Early-Weaning on Captive White-tailed Deer Fawns The welfare of white-tailed deer (Odocoileus virginianus) fawns orphaned during an early doe harvest is of management interest when the hunting and fawning seasons are temporally close. A 2-year study on early-weaned, captive white-tailed deer fawns was conducted to evaluate potential effects of early orphaning on growth and survival. Comparisons were made between survival of 60-day-old weaned fawns (TV = 28), 90-day-old weaned fawns (N = 21), and control fawns left with their does (N = 21). Jacob L. Bowman, H. A. Jacobson

Deer Harvest Characteristics During Compound and Traditional Archery Hunts Resource managers require accurate estimates of hunter success rates with various weapon types to predict annual harvests and design management strategies. We obtained harvest data for white-tailed deer (Odocoileus virginianus) on the McAlester Army Ammunition Plant in southeastern Oklahoma during periods of compound (1983— 1988) and traditional archery (1989-1995) hunting to compare hunter success rates and the sex and ages of deer harvested. Hunter success was greater (P = 0.001) with compound (¯x = 17.8%; SE = 1.3) than traditional archery equipment (¯x = 10.7%; SE = 0.9). Stephen S. Ditchkoff, E. R. Welch,Jr., R. L. Lochmiller, R. E.

Effects of Raccoon Hunting on White-tailed Deer Movement and Harvest Potential The impact of raccoon (Procyon lotor) hunting with trained hounds on movement, daily use area, and harvest potential of white-tailed deer (Odocoileus virginianus) was studied on Westvaco Corporation's North Whitener Tract in Jasper County, South Carolina, in winter 1993-94 and 1994-95. Two groups (treatment and control) of radioinstrumented deer were selected from a larger group of radio-collared deer. James D. Westerhold, T. T. Fendley, O. E. Baker, III

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

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

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.

Evaluation of Wild Turkey Trapping Techniques in West Virginia We studied efficiency of the rocket, rocket box, and cannon-net trapping techniques and the effects of the techniques on the physical condition of eastern wild turkeys (Meleagris gallopavo silvestris). We trapped 1,168 wild turkeys during a 5-year period (1989-1994). There were no differences in trapping efficiency (P > 0.05) among techniques. Fall (Sep-Oct) and winter (Jan-Apr) trapping efficiencies were not different (P > 0.05). Trappers with ≥1 year of experience had higher trapping efficiency (P < 0.0002) than trappers with no prior experience. James C. Pack, C. I. Taylor, D. A. Swanson, S. A. Warner

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

Effects of Winter Capture on Wild Turkey Hen Movement in Mississippi Analyses of movement patterns of free-ranging animals derived via radiotelemetry assumes that capture has no effect on the parameters of interest. To mitigate against potential biases, many researchers will censor locational data for an arbitrary post-capture duration (e.g., 2 weeks). To investigate validity of this assumption, we compared home range size, average inter-location distance, dispersion, and total distance moved between hens captured in a given interval to those captured in previous intervals. Data were from winter-captured hens in Kemper County, Mississippi, 1986-1992. Mike Weinstein, G. A. Hurst, B. D. Leopold

Attitudes of Wild Turkey Hunters Toward Potential Regulation Changes in Mississippi Numbers of wild turkeys (Meleagris gallopavo) and turkey hunters have increased greatly in the Southeast during the last 3 decades, and administrators and managers should be aware of hunter attitudes toward potential hunting regulation changes. Our objective was to determine attitudes of turkey hunters regarding regulations on use of hunter orange, baiting, and a fall either-sex harvest. We conducted a mail survey of turkey hunters (N = 4,026) who hunted turkeys in Mississippi during the 1994 spring gobblers-only season. John T. Forbes, K. D. Godwin, G. A. Hurst

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.

Activity Patterns of Dabbling Ducks Wintering in Coastal South Carolina Nearctic dabbling ducks (Anatini) use varied wintering habitats. Spatial and structural variability among these may translate into differing capabilities of habitats to meet behavioral and physiological requirements of ducks. Our study was conducted on the Santee River Delta (SRD) in South Carolina, an important wintering area for dabbling ducks in the Atlantic Flyway. Brian T. Gray, D. H. Gordon, R. M. Kaminski

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

We used mark-resight methods to estimate sighting proportions of American alligators (Alligator mississippiensis) during night-light and aerial helicopter surveys. Alligators ≥122 cm were captured during 5- to 12-day periods on Orange Lake and Lake Woodruff National Wildlife Refuge, Florida, and marked with paint on the dorsal neck area. Replicate helicopter surveys were subsequently flown on each area to record marked and unmarked individuals. Population estimates were calculated and compared with night-light and aerial counts of alligators ≥122 cm. Allan R. Woodward, K. G. Rice, S. B. Linda

Alligator Nest Temperatures and Hatchling Sex Ratios in Coastal South Carolina The relation between natural nest temperatures and hatchling sex ratios of American alligator (Alligator mississippiensis) has not been determined adequately. The few studies to date have been limited by study design, low sample size, and inadequate equipment. We investigated this relationship in 20 nests in impoundment habitat in South Carolina during 1995. Actual sex ratios were highly correlated (r = 0.971, P < 0.001) with sex ratios predicted from laboratory results, on the basis of mean nest temperatures between days 30-45 of incubation (temperature-sensitive period (TSP)).

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.

Deer Use of Riparian Zones and Adjacent Pine Plantations in Texas We monitored white-tailed deer (Odocoileus virginianus) use of riparian zones (RZs) and adjacent pine plantations of 3 age classes (young, 1 -3 years old; intermediate, 5-7 years old; and older, 9-13 years old) using radio telemetry for 2 years on a 1,300- ha study area near Alto, Texas. Riparian zones comprised 22.0% of the area; young, intermediate, and older pine plantations comprised 19.1%, 45.7%, and 13.2%, respectively. Micah L. Poteet, R. E. Thill, R. M. Whiting, Jr., R. L.

Effects of Planting Date and Nitrogen Fertilization Rate on Selected White-tailed Deer Forages We studied the effects of 3 planting dates (Sep, Oct, Nov) and 2 fertilization rates (the recommended nitrogen [N], phosphorus [P], and potassium [K] based on soil testing and twice the recommended N, with P and K) on rye (Secale cereale), oats (Avena sativa), and wheat (Triticum aestivum) planted for white-tailed deer {Odocoileus virginianus) from 1991 to 1993. Forage plantings established early (September) in the cool season produced the most forage during the season and maximized production during hunting season. John W. Bowers, N. A. Waer, H. L.

Deer Forage in Hardwood Stands following Thinning and Fertilization We conducted a 10-year study in oak-hickory stands in the Arkansas Ozarks to investigate the effects of intermediate thinning and nitrogen (N) fertilization on the annual production of understory vegetation. A total of 101 experimental plots was thinned to residual overstory densities of 40%, 60%, 80%, or 100% of full stocking. Nitrogen fertilizer (336 kg N/ha) was applied to a subset of plots in each thinning treatment. Understory species composition and biomass were estimated 1, 2, 3, 5, and 10 years after treatment.

Annual Cycles of Growth and Use of Chinese Privet by White-tailed Deer in Northwestern Georgia Chinese privet (Ligustrum sinense) is a common shrub in the southeastern United States, but no studies have examined white-tailed deer (Odocoileus virginianus) use of privet. We investigated the seasonality of deer use of privet browse and the effect of deer browsing on privet twig growth. We tagged and repeatedly measured about 200 privet twig clusters in forest and field-edge habitats at Chickamauga Battlefield Park (CBP) in northwestern Georgia during 2 consecutive years. Karl A. K.

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.

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

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.

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.

Expansion of the black bear (Ursus americanus) population outside White River National Wildlife Refuge, Arkansas, has caused local citizens to request reduction of the population. An estimate of black bear population size is necessary before any management recommendations can be made. We used 2 census methods to estimate population size. Hunter surveys of bear sightings during the 2-day firearm deer hunt were used in 1994 to estimate population size with a Petersen-Lincoln estimator. The survey yielded a population estimate of 213 bears (95% CI = 129-297). Jacob L. Bowman, M. J. Chanberlain, B. D. Leopold, H. A. Jacobson

Bobcat Habitat Use at Multiple Spatial Scales Habitat use occurs at several spatial scales; however, bobcat (Felis rufus) habitat use has not been investigated at multiple scales. Additionally, sex-specific differences in bobcat habitat use have been hypothesized but not tested. Therefore, we investigated habitat use of 30 bobcats (9 males, 21 females) from 1 January 1989 to 31 December 1993 on 2 study areas in east-central Mississippi. We investigated bobcat habitat use at 2 spatial scales: habitat use within the home range and habitat composition of the home range relative to habitat composition of the study area.

Habitat Preferences of Relocated and Resident Northern Bobwhite in Eastern Texas During 1990-1992, 291 northern bobwhite (Colinus virginianus) were captured, radio-tagged, and relocated from southern and eastern Texas to an intensively managed 563-ha eastern Texas study area; 139 resident birds were also captured, radiotagged, and released at the point of capture. We examined macro- and micro-habitat selection by relocated and resident birds. Xiangwen Liu, R. M. Whiting, Jr., D. S. Parsons, D. R. Dietz

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.

Aviation Uses in Wildlife Agencies and How to Get Started Over the past decade, Florida has undergone rapid suburbanization of its borderline wilderness areas. New airspace restrictions and low-level flight restriction over what are now populated areas have increasingly impeded aerial wildlife research and law enforcement patrol with fixed-winged aircraft. During the same decade, domestic marijuana cultivation in Florida's wilderness areas, especially Commission-maintained wildlife management areas, has increased dramatically.

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.

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.

Assessment of Conservation Agent Safety Training in Missouri As a result of an increasing frequency of assaults on conservation agents performing their duties, administrators of the Protection Division of the Missouri Department of Conservation requested Conservation Agent Training Academy staff look at the current status of officer safety training offered to agents. The division also decided to complete an extensive assessment of all training provided for conservation agents. To satisfy immediate needs and prepare a way to meet long-term needs, a Safety Needs Assessment was completed.

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.

Small watershed impoundments provide the principal recreational fishing opportunities within national forests in Mississippi. Relative abundance and stock structure of bluegiii (Lepomis macrochirus) and largemouth bass (Micropterus salmoides) were assessed by electrofishing 18 national forest impoundments during spring 1990, autumn 1990, and spring 1991. There were no significant yearto- year or seasonal differences in catch per unit effort (CPUE) or proportional stock density (PSD) for either species. Donald C. Jackson, N. J. Brown-Peterson

Changes in Shad and Largemouth Bass Dynamics and Sport Fishery Following a Disease-caused Fish Kill During spring and summer 1986, a massive disease-caused fish kill occurred on Lake Walter F. George, Georgia, which resulted in significant and longlasting changes in the fish populations of this reservoir. Prior to the fish kill, populations of both threadfin (Dowsoma petenense) and gizzard shad (D. cepedianum) were dominated by intermediate- and harvestable-size fish. Anglers reported largemouth bass (Micropterus salmoides) fishing was poor, and age analysis indicated poor recruitment for several years.

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

Development of a Trophy Largemouth Bass Fishery in Louisiana The management objective at Caney Creek Reservoir, a Louisiana lake impounded in 1986, was to produce trophy-size largemouth bass (Micropterus salmoides). Management actions included introduction of Florida bass (M s. floridanus), supplemental forage stocking, and initiation of length limit regulations. Prior to impoundment, the reservoir basin contained northern largemouth bass (M. s. salmoides) and intergrades between the northern and Florida subspecies.

Standardization of Missouri Angler Surveys One component in evaluating the need for or the result of a fishing regulation is an angler survey. In recent years, efforts have advanced the way an individual survey is designed, conducted, and analyzed. However, managing approximately 30-40 on-site angler surveys each year led Missouri to develop and implement stringent data processing guidelines. John S. Stanovick, P. Haverland

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

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

Hatchery Performance and Reuse of Domesticated White Bass Broodstock White bass (Morone chrysops) were reared to maturity and spawned in 2 consecutive years to evaluate their hatchery performance and potential for reuse. Egg production and hatching could not be statistically compared between 2- and 3-year-old fish due to estimation of size data and pooling of hatch data in 1994. Three-year-old virgin females had a mean production of 81,413 larvae/kg body weight and an egg hatching level of 62.9%. No statistical differences (P ≤ 0.05) in latency, egg and fry production, or hatching were detected between 3-year-old virgin and previously strip-spawned fish. Theodore I. J. Smith, W. E.
