Book excerpt: "A study to evaluate white-tailed deer winter range use in relation to forest stand and weather conditions was conducted during three winters from 1983-1986. Data were collected from 16.1 km (10 mi.) of ground transects and 20 radio-collared deer located on winter range in the study area. One hundred thirty seven telemetry locations were evaluated with a GEOSCAN cartographic program. The program scanned 40 ha (100 ac.) around each location to generate a frequency distribution of cover types from a digitized vegetation map. A winter severity index was used to classify transect and telemetry observations of deer use into mild, moderate and severe winter condition categories. Under mild winter conditions, white-tailed deer used 13 cover types in proportion to their availability on the winter range. Observed proportion of cover type use by deer under moderate and severe winter conditions differed from that expected. Deer utilized openings, lightly stocked plantations, and riparian pole-sized timber significantly less than availability and preferred upland pole and riparian sawtimber-sized stands. Multiple regression analysis of snow depth, percent canopy closure and aspect vs. deer use was significant, especially when snow depth exceeded 40 cm (13 in.). Discriminant function analysis was not particularly effective in identifying habitat variables to predict deer occurrence under mild and moderate conditions. The discriminating variables for severe winter conditions were one tree basal area variable, one diversity related variable, one aspect variable, and one stand type variable. Reductions in deer use one year following timber harvest ranged from 52-85% and were related to reductions in canopy closure. Overall rankings of cover type use derived from transects did not differ significantly from rankings obtained by telemetry. However, large differences in individual cover type rankings between techniques were observed in conifer plantations and upland sawtimber cover types. Rankings of cover type use derived from both techniques were correlated. The relationship between forest structural components on winter ranges and the silvicultura1 practices which affect them is discussed. Guidelines for winter range si1vicultcra1 treatments are proposed. Management implications of the guidelines are discussed. The distribution of winter range structural types in the study area was within recommended guidelines"--Leaf ii.

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.

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.

This book was released on 1996 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The white-tailed deer is one of the most studied animals in North America, yet much of the available information has been derived in ecosystems different from the Black Hills. The Black Hills are unique in that the dominant species, ponderosa pine, has excellent regenerative abilities. This attribute, combined with timber management practices and fire suppression efforts in the last century, has allowed pine to expand at the expense of other plant communities. A critical first step in maintaining viable white-tailed deer populations in the Black Hills is identifying key winter ranges. Given that protein and energy are limiting in winter forages in this region, the emphasis of management on these ranges should be to enhance forage quality and quantity. Prescribed burning and timber harvest can be used to enhance the forage base. Grazing systems designed to remove livestock from these key winter ranges before late summer will provide a greater portion of the woody plants for deer use. Research needs focus on understanding how changes in Black Hills community patterns have influenced deer foraging strategies and habitat use, and on the need for ecologically based techniques to maintain consistent forage quality. Addressing these needs in an ecosystem framework will result in habitat for not only deer, but also for a multitude of other animal and plant species.
