Book Synopsis Roosevelt Elk Habitat Use in the Oregon Coast Range by : Gary William Witmer
Download or read book Roosevelt Elk Habitat Use in the Oregon Coast Range written by Gary William Witmer and published by . This book was released on 1981 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Daily and seasonal habitat use by Roosevelt elk was investigated in the Oregon Coast Range on managed, public forestland. Over 3,700 locations of 6 radio-collared cow elk were recorded during 12 consecutive months. Two elk formed part of a north band and 4 elk were part of a south band. Home ranges for elk bands were mutually exclusive and enclosed areas of 400 ha or less each season. Heavily used central cores of activity comprised a small portion of the total home range. Seasonal home ranges of a given band overlapped substantially and were largest in calving and summer seasons. Cow elk of a given band were most often associated with one another during spring, rut and winter seasons and were otherwise more dispersed. Elk exhibited preferences for old-growth forest and hardwood stands over mixed forest and dense, young conifer stands. Brushy clearcuts were utilized more than new clearcuts for foraging. Use of new clearcuts increased in winter. Elk preferred southerly aspects throughout the year, avoided roads (especially paved roads), and did not venture far from forest/clearcut edges. During calving season, cow elk spent more time in cover and utilized areas that were characteristically of lower elevation, gentler slope, greater seclusion and were closer to water than the rest of the year. Elk appeared unaffected by weather during the mild winter of the study and sought out cover during warmer periods of the day during all seasons. A consistent daily pattern of habitat use was for elk to forage on brushy clearcuts during early and late daylight hours and to retreat to an old-growth stand to bed and/or loaf through the midday period The pattern of several hours of activity followed by several of inactivity appeared to extend through the night, although elk were less active at night. Cover use, especially of dense, young, second-growth stands, increased and movement decreased during the hunting season. Despite variability in seasonal and individual elk habitat use, discriminant analyses suggested that cover types, adjacent cover types and aspects were the most promising of the parameters measured for the prediction of habitat use patterns of Roosevelt elk. Recommendations are proposed for the effective integration of management for elk and other forest resources.
Book Synopsis The Effects of Forage Improvement Practices on Roosevelt Elk in the Oregon Coast Range by : Rosemary J. Stussy
Download or read book The Effects of Forage Improvement Practices on Roosevelt Elk in the Oregon Coast Range written by Rosemary J. Stussy and published by . This book was released on 1993 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forage availability, diets, distribution, and productivity were compared for Roosevelt elk, Cervus elaphus roosevelti, using improved (i.e. seeded, fertilized, and grazed) and untreated areas of the Oregon Coast Range. Seasonal forage availability was substantially different on 1-year-old improved and untreated clearcuts, but the differences diminished by clearcut age 4 and essentially disappeared by clearcut age 7. Elk diets, as evaluated by fecal analysis, were similar in plant species composition and DAPA concentrations on both areas. There was no significant difference in estimated calf birth weights or survival, or in pregnancy and lactation rates, kidney and metatarsal marrow fat concentrations, or breeding dates of adult cows using improved and untreated areas. Summer and winter calf ratios were similar in 7 of 8 seasons sampled. There was no significant difference in home range or core area size, and distances traveled were similar on both areas in all seasons except winter. Elk exposed to summer sheep grazing were displaced an average of 1211 m (SD = 28 m) for an average of 14 weeks (SD = 5 weeks). Elk using improved areas stayed closer to forage areas in spring, but otherwise there was no significant difference in proximity to forage. Elk from both areas demonstrated preferential use of meadows, and used other forage areas in proportion to their availability. The combined results indicated that the forage improvement practices were ineffective in producing any measurable benefits for elk.
Book Synopsis Population Ecology of Roosevelt Elk by : Butch Weckerly
Download or read book Population Ecology of Roosevelt Elk written by Butch Weckerly and published by University of Nevada Press. This book was released on 2017-09-27 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Roosevelt elk populate the parks along California’s north coast and comprise the largest land mammals in the parks, some weighing up to 1,200 pounds. They are a stable terrestrial land mammal population, a fixture in the parks, but still require ongoing stewardship and management. In a study spanning more than twenty years, Weckerly made key observations and conducted various investigations under a multitude of ecological conditions. Few authors have dedicated this much time and effort into a single research area. It is a testament to perseverance that his groundbreaking study of the Roosevelt elk was so successful. He was able to document the independent dynamics of several herds of female elk, experience the extinction of one of their subpopulations, and record scientific conclusions in the context of resiliency and redundancy of the elk population. This book will be of considerable interest to those who investigate the ecology of big game animals, including naturalists, hunters, and individuals with particular interest in Redwood State and National Parks. It is an important book that contributes substantially to the persistence and viability of Roosevelt elk in the parks and the surrounding area.

Book Synopsis Influence of Limited Access Roads on Roosevelt Elk in the Oregon Coast Range by : Eric K. Cole
Download or read book Influence of Limited Access Roads on Roosevelt Elk in the Oregon Coast Range written by Eric K. Cole and published by . This book was released on 1996 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: No studies have evaluated the effects of limited vehicle access on movements, survival and habitat use of Roosevelt elk (Cervus elaphus roosevelti) . We installed twenty gates, restricting motorized vehicle access by the public in seven discrete Road Management Areas (RMAs), comprising 35% of the study area. We radio-tracked 31 cow elk for 13 months in a 38,000 ha area of the Oregon Coast Range. Prior to the installation of the gates, 20 of these elk had been tracked for 14 months, allowing a paired comparison of elk movements and habitat use before and during the limited access period. The percentage of elk home ranges or core areas within the RMAs did not differ between periods, but there was a clear decrease in daily movement of elk during the limited access period. Survival rates increased during the limited access period and declined after the removal of the gates. During the limited access period, there was a significant increase in the use of open, foraging habitats and areas 150 m from roads. We conducted habitat selection analysis on vegetative cover types, distance from roads and distance from water. In general elk use of vegetative cover types was not significantly different from availability (p0.05). Elk avoided areas

Available in PDF, EPUB and Kindle. Book excerpt: Few studies have evaluated non-migratory Roosevelt elk (Cervus elaphus roosevelti) interactions and habitat use on lands undergoing extensive timber removal. We captured and radio-tracked for 14 months representatives from 29 different bands of elk across a 37,000 ha area of Oregon's Coast Range. We identified 6 habitat variables within individual elk home ranges and across the study area. In general, elk use of these habitats within individual home ranges was not significantly (
Book Synopsis The Elk of North America by : Olaus J. Murie
Download or read book The Elk of North America written by Olaus J. Murie and published by Stackpole Books. This book was released on 2017-09-15 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an outstanding treatise on one of America’s most widely hunted and most important big-game animals. Although thousands of sportsmen take to the field each year in quest of trophies, the perpetuation of elk hunting in America depends entirely upon proper management of the herds. Whether management succeeds or fails in future years will depend upon how well the public understands the problems of the game administrators and of the animals themselves. Everything the sportsman or naturalist would wish to know about the elk in included in this new volume. Habits, food preferences, seasonal movements, anatomy, antler development, and management problems are interestingly and thoroughly discussed. Written by one of America’s greatest field naturalists, this new book has behind it a lifetime spent in intimate study of the subject. Dr. Murie is recognized as the world’s foremost authority on the American elk and his comprehensive research on elk in the Jackson Hole National Monument forms the basis for this book. Everyone interested in America’s wildlife will want this volume in his library. The book is copiously illustrated with half-tone and original line drawings by the author.
