Book Home Range and Habitat Use by Roosevelt Elk in Olympic National Park Washington

Download or read book Home Range and Habitat Use by Roosevelt Elk in Olympic National Park Washington written by Kurt Jeffrey Jenkins and published by . This book was released on 1979 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research provides information on the distribution of an unexploited Roosevelt elk population in unaltered habitat in Olympic National Park. Radio-telemetry was used to document home range and habitat use by 11 adult cow elk in the Hoh Valley during March 1978, from 10 June-15 September 1978, and from 1 January-20 March 1979. That information provides a baseline for comparison with managed herds adjacent to the park and identification of long term changes in the distribution of elk in the Hoh Valley. Four groups of cow elk were identified in the study area. Cow groups were stable; elk within a group used a common home range and were highly associated. Home ranges of elk from adjacent groups overlapped but there was no permanent interchange of collared elk between groups during the period of study. There was no significant difference between mean summer and mean winter home range size; however, summer home range was larger than winter home range in five, of seven, comparisons. Average home range area of collared elk was 1034 ha during summer and 1003 ha during winter. Daily movement of elk was greater during summer than during winter; minimum daily movement distance averaged 843 m during summer and 676 m during winter. Movement of cow elk with newly born calves in June was considerably less than movement of elk without calves. The habitat use of radio-equipped elk was studied in relation to 13 habitat units on national park land and 11 units on non-park land. Collared elk were found primarily in habitat units on the valley floor during both seasons, although there was seasonal variation in the use of those units. Elk were least selective of habitat during winter, most selective during late winter and moderately selective during summer. Alder flats were selected by each collared elk during late winter and were identified as important elk habitat in the Hoh Valley because use of such areas was prevalent during a nutritionally important time of year for cow elk. Other patterns of habitat use were discussed in relation to thermal and nutritional characteristics of the watershed.

Book Seasonal Movements and Distribution of Migratory Roosevelt Elk in the Olympic Mountains Washington

Download or read book Seasonal Movements and Distribution of Migratory Roosevelt Elk in the Olympic Mountains Washington written by Gregory L. Schroer and published by . This book was released on 1986 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seasonal movements, home ranges, core areas and habitat use patterns of hunted, migratory Roosevelt elk (Cervus elaphus roosevelti) were investigated on the Olympic Peninsula, Washington. Radio telemetry was used to obtain more than 3,100 locations of 9 elk from May 1984 - March 1985, and November - December, 1985. Radio-collared elk were in 2 herds that migrated approximately 32 km, and 1500 m in elevation, between winter ranges at sea level to summer ranges at timberline. Migratory routes primarily were in riparian areas on narrow valley floors. Home ranges were largest during late autumn ([x-bar] = 43.1 square km) and smallest during summer ([x-bar] = 5.9 square km). Minimum daily movements of elk followed a similar seasonal pattern and were largest during late autumn ([x-bar] = 1119 m) and smallest during summer ([x-bar] = 602 m). Core areas in summer and rutting seasons occurred in subalpine parklands among precipitous, rocky ridges. Core areas during winter and calving seasons were primarily on the valley floors and lower portions of valley walls, areas that also have the greatest degree of human development. Elk used areas less than 300 m from residences and paved roads in winter core areas primarily at night. In addition, distances of elk from paved roads and residences were significantly greater during day-time hours, which was also the period with the greatest amount of motor vehicle traffic. In summer and rutting seasons, elk selected subalpine parkland habitats, and used coniferous forests in proportions less than expected on the basis of availability. In winter, deciduous and deciduous/coniferous forests were used in greater proportions than expected, whereas coniferous forests (

Book Biodiversity Conservation in Transboundary Protected Areas

Download or read book Biodiversity Conservation in Transboundary Protected Areas written by National Research Council and published by National Academies Press. This book was released on 1996-09-27 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recognizing the increasing rate of species loss on a global scale and that neither pollution nor ecosystems respects political boundaries, cooperation on many different levels is required to conserve biodiversity. This volume uses four protected areas that Poland shares with its neighbors as case studies to explore opportunities to integrate science and management in transboundary protected areas in Central Europe for the conservation of biodiversity. Specific topics include biodiversity conservation theories and strategies, problems of wildlife management, and impacts of tourism and recreational use on protected areas.

Book Roosevelt Elk Habitat Use in the Oregon Coast Range

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 Seasonal Movements and Habitat Use of Migratory Elk in Mount Rainier National Park

Download or read book Seasonal Movements and Habitat Use of Migratory Elk in Mount Rainier National Park written by Kevin Craig Cooper and published by . This book was released on 1987 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seasonal movements, habitat use, home range selection, and group interactions of Roosevelt elk (Cervus elaphus roosevelti) were studied in the upper White River watershed in west-central Washington. Over 2000 locations of 14 elk were recorded by radio-telemetry from April 1983 to December 1984. During winter, two herds used clearcut lands near the mouth of the West Fork of the White River (about 610m MSL). One herd migrated four km to a clearcut spring range at 1070m MSL, whereas the other remained on the winter range during spring. Both herds migrated 15 km up river corridors to subalpine parklands within Mount Rainier National Park where they remained from July to October. A third herd wintered in unmanaged old-growth forest within Mount Rainier National Park along bottomlands of the White River Valley (915m MSL). That herd then moved 5-10 km upriver toward summer range during June, and arrived on subalpine summer range the first week in July. All herds migrated back to winter ranges via river corridors following heavy snowfall on November 15, 1983 and October 15, 1984. Winter ranges of elk in both the managed and unmanaged segments of the study area were oriented along the valley floodplain. Consequently, ranges of elk in the managed forest contained greater proportions of old-clearcuts (12-30 years) and alder habitats (which occurred primarily on the floodplains) than existed in the valley. Preferred old-clearcut habitats contained a mosaic of dense, regenerating douglas-fir interspersed with open-canopied foraging areas. Old-growth and young clearcuts, which were located primarily on upland sites, were underrepresented in elk home ranges compared to their availability in the valley. Elk were generally unselective of habitats within the home range. On the spring range of one herd, mid-age clearcuts (4-12 years) and young clearcuts (0-4 years) occurred in a greater proportions than in the valley. Preferred habitats contained many mesic seeps and draws. Spring range in the unmanaged forests consisted of old-growth valley bottom habitats. Habitat preferences of elk varied between two summer ranges within Mount Rainier National Park. In general, elk preferred open subalpine forests, Abies lasiocarpa/Valeriana sitchensis habitat, and alder slide habitats. Additionally, Dry Grass, and Lush-low Herbaceous habitats tended to be used in proportions greater than availability.
