This book was released on 1986 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted using radio telemetry to evaluate distribution, movements, activity, and habitat use by white-tailed deer (Odocoileus virginianus) on two areas along the lower Yellowstone River in eastern Montana during summer 1982 and 1983 and winter 1984. Deer distribution centered on river bottomlands, though some deer made daily or seasonal movements to adjacent uplands on the Intake area. Deer movements were short and restricted to riparian cover during the day, but increased and extended to agricultural fields up to 2.5 km from cover at night. Movement to and use of fields increased through summer and from summer to winter and appeared greater on the Intake than Elk Island study area. Well defined peaks in deer activity and movement occurred at sunrise and sunset; lesser peaks occurred near midnight and noon. Peak use of agricultural fields occurred from 1-2 hours after sunset until midnight. Seasonal minimum convex polygon home range sizes for individual deer varied from 0.29 km^2 to 10.0 km^2. Adult females had the smallest home ranges, averaging 0.87 km^2 in summer and 1.8 km^2 in winter. Total (24-hour) home range size varied by sex and age of the deer, season, and study area. Home ranges based only on daytime relocations averaged half as large as total home ranges in summer and 28% of the total in winter and did not differ between seasons and study areas. Among riparian cover types, deer selected for mid-to-late seral communities (mature cottonwood, shrub, green ash, and mature willow) with tall dense cover; grasslands were avoided. Among croplands, deer preferred alfalfa in summer and ungrazed alfalfa, sugar beets, and winter wheat in winter. Differences in selection and use of crops between study areas and seasons were related to availability influenced by cropping, harvest, and post-harvest grazing and field treatment practices. Overall, natural riparian cover and agricultural croplands were the two major components of deer habitat. These combined with topography and physiography of the river valley, and other land use and operational practices to influence deer distribution movements and home range size, activity, and use of specific cover types. --Abstract.

This book was released on 2012 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite decades of widespread interest and extensive research, many questions remain about white-tailed deer (Odocoileus virginianus) seasonal movements and habitat use in the southeastern United States. Certain seasons, like parturition and breeding, have been studied in detail; however, there is a general lack of specific, year-round information on herd dynamics. The availability of GPS-based telemetry has made studies of year-round movements feasible, and there has been a recent increase in data of this type. During 2009-2011, I assessed deer habitat use and movement dynamics in Northwest Louisiana. Barksdale Air Force base consists of 8,900 ha of bottomland hardwood and upland managed pine stands in Bossier Parish, LA. I placed GPS radiocollars on 15 adult male and 15 adult female white-tailed deer and obtained 1 fix per hour for approximately one year. I quantified annual and monthly home range sizes and habitat composition, and seasonal movement parameters for adult white-tailed deer. Adult home range and core area sizes were larger during the winter months than the summer months for both genders. Male monthly home ranges varied from 97 to 380 ha and were larger than female home ranges (44-181 ha; P 0.0001) in all months. Habitats were utilized similarly by males and females. Shrub habitats and hardwood bottoms were utilized more than expected throughout the year while thinned and wet hardwood bottoms and scrub habitats showed little utilization. Openings such as fields, food plots, and developed areas were preferred when present as patches in primarily forested areas but were avoided when found as large uninterrupted tracts of land. All other habitat types were similar in preference (P 0.05) and showed little variation among months. Overall, males moved more than females for daily movement rate and extreme daily distance. Movement peaked for both genders in the winter season around breeding. I found that movement rates and patterns differed greatly between years, perhaps more than variation among seasons. Ten out of 14 female deer made breeding season excursions outside of normal movements, presumably to seek additional mating opportunities. Although movements declined around the predicted date of parturition, I did not find that movements in the weeks surrounding known parturition dates differed from pre- or post-parturition based on vaginal implant transmitter expulsion dates (P > 0.0664). I also quantified fawn survival, home range size, and habitat composition up to three months of age. Overall fawn mortality was 50%, which is generally consistent with other studies in the southeast. I observed differences in fawn mortality between different habitats on base, with 5 of 6 fawns predated before 30 days on the hardwood-dominated western half and 1 of 6 fawns dying (from apparent internal trauma and subsequent starvation) before 30 days on the pine-dominated eastern half. Fawns in the hardwood ecotype had larger home ranges (P = 0.0011) and core areas (P = 0.0018) than the pine ecotype but doe home ranges and core areas did not differ by ecotype (P > 0.2578). Known parturition sites were closer to habitat edges (P = 0.0242) and developed areas (P = 0.0476) than random sites within doe home ranges, suggesting does were seeking areas of their home range with more cover at parturition. The majority of fawns utilized habitats differently than their dams, with fawns being located more often in developed areas and mixed stands and does being located more often in mature pine stands and shrub habitats. Movement and home range data suggest white-tailed deer at Barksdale are finding adequate year-round resources to meet their needs. Fawn survival appeared to vary considerably depending on habitat at the base, and the provision of additional fawning cover in the form of small openings or timber harvests in areas of mature forest may aid in survival. Female movement data and summer habitat use data raise the possibility that deer density is below target density for harvest management at the site. An accurate estimate of density should be obtained and it may be advisable to consider changes to harvest regulations to increase herd density.

This book was released on 1974 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the life history, population dynamics, and ecological relationships of the Columbian white-tailed deer (Odocoileus virginiarius leucurus) was conducted on the Washington mainland, Columbian White-tailed Deer National Wildlife Refuge during 1972-1973 to provide information for management of this endangered subspecies. A total of 18,077 observations of deer recorded during 213 morning and evening periods along two observation routes provided information concerning use of plant communities, activity, group composition, and sex and age structure. Detailed behavior observations were recorded during 25 morning and evening periods. Vegetation on the study area was categorized into five major community groupings of rush, thistle, grass, horsetail, and forest Deer were observed most often in those communities that provided both cover and forage. Communities providing forage without cover were most used where cover was adjacent. The population on the study area during the winter was estimated between 200 and 230 deer or one, deer per 3.4-3.9 hectares (one deer per 8.5-9.8 acres). A buck:doe:fawn ratio of 34:100:35 was calculated for November. Average group size of deer while grazing was 2.2 animals The major classification of group size throughout, the year was of single deer. Numbers of individuals within groups were highest during winter. Overt aggression between individuals was observed infrequently. Frequency of aggressive behavior was greatest during cold weather. Bucks were always dominant over does and fawns, and does were always dominant over fawns. Grazing was numerically the major activity observed. Deer grazed more and rested less in summer than during winter. Copulations may occur primarily at night. Home ranges of bucks were 1arger than those of does, and home ranges of yearlings were larger than those of adults. Average home range size of the Columbian white-tailed deer was smaller than that reported for other subspecies. Deer avoided close association with cattle and used those areas where cattle densities were lowest or where cattle were not present. Deer showed preference for improved pasture prior to introduction of cattle for seasonal grazing.

Book excerpt: Columbian white-tailed deer (Odocoileus virginianus leucurus, CWTD) are a geographically isolated and federally endangered sub-species for which there is a paucity of recent ecological information. I described and examined sources of variation in spatial use patterns (i.e. home range, areas of concentrated use, and movements), habitat associations, and survival for adult and fawn CWTD in Douglas County, Oregon. I radio-collared and monitored 64 adult CWTD and 36 newborn fawn CWTD from ca. December 1995 - September 1998. Locations for adults were obtained from September 1996 - December 1998. Locations for fawns were obtained from June - September, 1997 - 1998. Spatial use estimates for adults tended to be variable among deer. Mean 95% fixed kernel home range size was 74.5 ha (CV = 83%), while areas of concentrated use averaged 8.5 ha (CV = 93%). The sexes appeared to be partitioning space because males had larger home ranges, areas of concentrated use (which are analogous to core areas), and movements than females. Deer inhabiting human-influenced areas (suburban deer) consistently exhibited smaller movements and used less space than those away from human influence (wild deer). Mean home range size, area of concentrated use size, and distance between successive locations was generally greatest in fall and lowest in winter. Site fidelity to seasonal home ranges and areas of concentrated use was lowest between fall-winter and summer-fall. Unexpectedly, size of home ranges and areas of concentrated use were positively correlated with cover type heterogeneity. Annual adult survival rates averaged 0.73. Neither annual survival rates nor functions differed by sex or type. Survival over the entire 3 year study was low (0.39). Most deer died in winter from a combination of emaciation and disease and generally were in poor body condition. Oak-hardwood woodland, riparian, and oak-hardwood savanna shrub were the most frequently used cover types. On an annual basis, the majority of deer (31%) selected riparian areas. The frequency of selection of all non-riparian cover types was

Available in PDF, EPUB and Kindle. Book excerpt: The original, 2006 edition of Timothy Edward Fulbright and J. Alfonso Ortega-S.’s White-Tailed Deer Habitat: Ecology and Management on Rangelands was hailed as “a splendid reference for the classroom and those who make their living from wildlife and the land” and as “filling a niche that is not currently approached in the literature.” In this second, full-color edition, revised and expanded to include the entire western United States and northern Mexico, Fulbright and Ortega-S. provide a carefully reasoned synthesis of ecological and range management principles that incorporates rangeland vegetation management and the impact of crops, livestock, predation, and population density within the context of the arid and semiarid habitats of this broad region. As landowners look to hunting as a source of income and to the other benefits of managing for wildlife, the clear presentation of the up-to-date research gathered in this book will aid their efforts. Essential points covered in this new edition include: White-tailed deer habitat requirements Nutritional needs of White-tailed deer Carrying capacity Habitat management Hunting Focused across political borders and written with an understanding of environments where periodic drought punctuates long-term weather patterns, this revised and expanded edition of White-Tailed Deer Habitat: Ecology and Management on Rangelands will aid landowners, researchers, and naturalists in their efforts to integrate land management and use with sound ecological practices.

Available in PDF, EPUB and Kindle. Book excerpt: For most of the last century, range management meant managing land for livestock. How well a landowner grew the grass that cattle ate was the best measure of success. In this century, landowners look to hunting and wildlife viewing for income; rangeland is now also wildlife habitat, and they are managing their land not just for cattle but also for wildlife, most notably deer and quail. Unlike other books on white-tailed deer in places where rainfall is relatively high and the environment stable, this book takes an ecological approach to deer management in the semiarid lands of Oklahoma, Texas, and northern Mexico. These are the least productive of white-tail habitats, where periodic drought punctuates long-term weather patterns. The book's focus on this landscape across political borders is one of its original and lasting contributions. Another is its contention that good management is based on ecological principles that guide the manager's thinking about: Habitat Requirements of White-Tailed Deer White-Tailed Deer Nutrition Carrying Capacity Habitat Manipulation Predators Hunting Timothy Edward Fulbright is a Regents Professor and the Meadows Professor in Semiarid Land Ecology at the Caesar Kleberg Wildlife Research Institute, Texas A&M University-Kingsville.
