Available in PDF, EPUB and Kindle. Book excerpt: Black-tailed deer (Odocoileus hemionus columbianus) and other forest herbivores depend on abundant and nutritious understory vegetation found in open-canopy and young, early-seral forests. Forage management activities such as logging, thinning and using silvicultural herbicides have the potential to alter the quality and quantity of forage available to herbivores. Therefore, I compared nutrient intake and estimated nutritional carrying capacity of black-tailed deer between stands that received herbicide treatments paired with those that did not in Douglas-fir/western hemlock forests of western Washington, and investigated how these responses change as forests age from early seral stages to canopy closure (2 -- 20 years post-harvest). I measured understory vegetation biomass, plant species nutritional quality, and overstory characteristics of each forest stand. Additionally, I measured diet composition, diet quality and nutrient intake of tractable black-tailed deer within each paired stand. I found that herbicide use decreased the amount of understory biomass useable for foraging deer and decreased their daily digestible energy intake, especially in the first 3 years of stand establishment. Even so, early seral habitat, regardless of herbicide use, provided more forage and higher daily energy intake for deer than closed canopy stands (14 yrs +) or mid-seral stands. Using data from these experiments, I also investigated how the resolution of data collection (e.g., plants vs. plant parts) influences estimates of plant selection and nutritional carrying capacity, and how well measures of forage abundance and quality predict nutrient intake of black-tailed deer. I found that treating plant parts (i.e., stems and leaves) as separate food items did not influence how plant species were categorized as selected, neutral or avoided, but increased estimates of nutritional carrying capacity. In addition, measures of forage resources that included both biomass and quality or selection status by deer better predicted daily digestible energy intake of tractable black-tailed deer.

This book was released on 1993 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spruce budworm defoliation, clearcutting for salvage, and prescribed burning of clearcut areas on deep and shallow soils influenced deer and moose foraging in eastern Maine spruce-fir forests from 1980 to 1984. Plant standing crop biomass, seasonal plant selection by tractable moose and white-tailed deer, and digestible energy for deer and moose were determined for each treatment. Early successional plant species were most abundant on burned areas, and were common on clearcut areas. Increase in biomass after defoliation was substantial. Deer and moose ate many of the same plant species, but in different proportions. Deer found more desirable foods on deep than on shallow soils and were more selective of plant parts than moose. Deer digested their diets slightly better than moose from late spring through fall. Deer obtained more digestible energy than moose during fall and early winter on all treatments. Moose obtained more digestible energy than deer during spring and summer on burned areas where forage was abundant. Available energy by treatment was significantly different for moose year round and for deer during spring and fall: clearcut and burn clearcut >defoliated >undefoliated (control).

Download or read book Biology and Management of White-tailed Deer written by David G. Hewitt and published by CRC Press. This book was released on 2011-06-24 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the Wildlife Society Outstanding Edited Book Award for 2013! Winner of the Texas Chapter of The Wildlife Society Outstanding Book Award for 2011! Winner of a CHOICE Outstanding Academic Title Award for 2011! Biology and Management of White-tailed Deer organizes and presents information on the most studied large mammal species in the world. The book covers the evolutionary history of the species, its anatomy, physiology, and nutrition, population dynamics, and ecology across its vast range (from central Canada through northern South America). The book then discusses the history of management of white-tailed deer, beginning with early Native Americans and progressing through management by Europeans and examining population lows in the early 1900s, restocking efforts through the mid 1900s, and recent, overabundant populations that are becoming difficult to manage in many areas. Features: Co-published with the Quality Deer Management Association Compiles valuable information for white-tailed deer enthusiasts, managers, and biologists Written by an authoritative author team from diverse backgrounds Integrates white-tailed deer biology and management into a single volume Provides a thorough treatment of white-tailed deer antler biology Includes downloadable resources with color images The backbone of many state wildlife management agencies' policies and a featured hunting species through much of their range, white-tailed deer are an important species ecologically, socially, and scientifically in most areas of North America. Highly adaptable and now living in close proximity to humans in many areas, white-tailed deer are both the face of nature and the source of conflict with motorists, home-owners, and agricultural producers. Capturing the diverse aspects of white-tailed deer research, Biology and Management of White-tailed Deer is a reflection of the resources invested in the study of the species’ effects on ecosystems, predator-prey dynamics, population regulation, foraging behavior, and browser physiology.

This book was released on 2023-04-27 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Black-tailed and mule deer represent one of the largest distributions of mammals in North America and are symbols of the wide-open American West. Each chapter in this book was authored by the world’s leading experts on that topic. Both editors, James R. Heffelfinger and Paul R. Krausman, are widely published in the popular and scientific press and recipients of the O. C. Wallmo Award, given every two years to a leading black-tailed and mule deer expert who has made significant contributions to the conservation of this species. In addition, Heffelfinger has chaired the Mule Deer Working Group sponsored by the Western Association of Fish and Wildlife Agencies for more than 15 years. This working group consists of the leading black-tailed and mule deer experts from each of 24 states, provinces, and territories in western North America, putting them at the forefront of all conservation and much of the research on this species. The book represents all current knowledge available on these deer, including how changing conditions such as fires, habitat alteration and loss, disease, climate change, socio-economic forces, energy development, and other aspects are influencing their distribution and abundance now and into the future. It takes a completely fresh look at all chapter topics. The revisions of distribution, taxonomy, evolution, behavior, and new and exciting work being done in deer nutrition, migration and movements, diseases, predation, and human dimensions are all assembled in this volume. This book will instantly become the foundation for the latest information and management strategies to be implemented on the ground by practitioners and to inform the public. Although this book is about deer, the topics discussed influence most terrestrial wildlife worldwide, and the basic concepts in many of the chapters are applicable to other species.

This book was released on 2014 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Variations in nutritional quality of natural forages for black-tailed deer (Odocoileus hemionus) was studied in the summer and winter in southeast Alaska. Freeze-dried samples of 17 summer forages collected in early July and 10 winter forages collected in February from three replicate sites each of shady forest understory and open, sunny habitat were analyzed and compared for their concentrations of digestible protein, digestible dry matter, and digestible energy. Data from each forage, ranging from forb and shrub leaves to woody twigs, were analyzed separately in a single-factor analysis of variance experimental design. Only five to seven of the summer forages different significantly (P
Book Synopsis Influences of Fuel Reduction Treatments on the Nutritional Ecology of Deer in Northeastern Washington by : Iver Thorin Hull

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, low-elevation dry forests in the inland northwest were structured to support light fuel loads and frequent low-severity fires. More recently, fire suppression has shifted the structure of these forests to have thick, continuous overstories with densely-stocked trees, and heavy fuel loads that can lead to high-severity, stand replacing wildfires that may threaten human safety and further alter natural forest communities. In addition, closed canopy, densely-stocked forests reduce light penetration to the forest floor, which can limit production of herbaceous and woody understory vegetation that can serve as forage for native herbivores. To restore historic conditions, promote healthy forests, and reduce wildfire risk, forest managers have implemented fuels reduction treatments. To determine whether these treatments improve the quality and quantity of forage resources for deer, we measured biomass, plant species composition, and nutritional quality of understory vegetation in treated and untreated forest stands that ranged from 2 – 20 years since treatment and 2 – 100% canopy cover in the Colville National Forest of northeastern Washington. We also measured diet quality and composition, nutrient intake, and foraging mechanics of mule deer (Odocoileus hemionus) and white-tailed deer (Odocoileus virginianus) using bite-count methods with tractable, hand-raised deer. In addition, we tested the ability of LiDAR-derived metrics of understory vegetation density to determine understory vegetation biomass remotely. Our results showed that understory vegetation biomass roughly doubles with a 50% reduction of canopy cover from fuels reduction treatments, and that the biomass of plants that are most important to deer increases with time since treatment, but begins declining approximately 14 years post-treatment. Increases in understory vegetation biomass, in turn, allowed deer to harvest food faster and increase their daily intake of digestible energy, which allowed them to meet maintenance requirements of dietary digestible energy and protein in our sample sites. Our LiDAR-based estimates of understory biomass correlated to field sampling when the amount of time between sampling methods was constrained to 3 years and canopy cover was

Book Synopsis Composition of Diets Selected by Sitka Black-tailed Deer on Channel Island, Central Southeast Alaska by : Thomas A. Hanley
Download or read book Composition of Diets Selected by Sitka Black-tailed Deer on Channel Island, Central Southeast Alaska written by Thomas A. Hanley and published by . This book was released on 2014 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Composition of diets selected by tame but free-ranging deer in a natural forest environment was studied throughout a 24-month period and summarized by mean monthly percentage composition on the basis of dry-matter intake. A modification of the standard bite-count method of diet determination was used. All forages were identified by species and plant part (leaf, twig). Major forages comprising the diet were identified seasonally and considered in relation to their role in the nutritional ecology of the deer. Overall, a simple but consistent pattern was evident in the data. When green, leafy forages (herbs and shrub leaves) were available, they were consistently targeted by the foraging deer, but as they became less available in winter, and especially with their burial by snow, diet composition shifted to less digestible woody forages (shrub twigs and conifer foliage) supplemented with highly digestible arboreal lichens. Although a wide array of potential forages are available during the growing season, dietary options shrink to a narrow range of important evergreen forbs, a few ferns, shrub twigs, and lichens in winter.
