From the forest to the sea : a story of fallen trees

Creator:: Maser, Chris, Tarrant, Robert F., Trappe, James M., and Franklin, Jerry F.
Abstract:: Large fallen trees in various stages of decay contribute much-needed diversity of ecological processes to terrestrial, aquatic, estuarine, coastal beach, and open ocean habitats in the Pacific Northwest. Intensive utilization and management can deprive these habitats of large fallen trees. The publication presents sound information for managers making resource management...

Habitat relationships of small terrestrial vertebrates and invertebrates in managed forests in the southern Oregon Cascades

Creator:: McDade, Kirsten Ayn
Abstract:: Silviculture systems that involve commercial thinning may provide higher quality wildlife habitat than traditional clearcut systems, yet such systems have not been vigorously tested. This prospective study examined forest floor animal abundance and habitat relationships under three different silviculture conditions: clearcuts, commercial thins, and uncuts. Eighteen stands, six per treatment,...

Daily activity patterns, survival, and movements of red tree voles (Arborimus longicaudus) in western Oregon

Creator:: Swingle, James Kerr
Abstract:: We radiocollared a sample of 61 red tree voles in Douglas County, Oregon and monitored their movements to determine daily, seasonal, and sexual differences in behavior and home range attributes. We also collected information on nest attributes, survival, and dispersal of the radiocollared voles. Individual voles were monitored for periods...

A preliminary investigation of the spotted owl in Oregon

Creator:: Forsman, Eric D.
Abstract:: Between 1970 and 1974, data were collected on the distribution and biology of the spotted owl (Strix occidentalis) in Oregon. One-hundred and sixteen pairs and seven single birds were located. Spotted owls occurred throughout the mountains of western Oregon and on the east slope of the Cascade Range at least...

Taxonomy and reproduction of Microtus canicaudus

Creator:: Tyser, Robin W.
Abstract:: The taxonomic status of Microtus canicaudus was compared with that of a morphologically similar vole, Microtus montanus. Four means of comparison were utilized: hybridization experiments, comparative karyology, growth distinctions (total length and body weight), and qualitative behavioral observations. The hybridization experiments indicated that, while the incidence of pregnancy of M....

Soil fungal hyphal dynamics and seasonal hypogeous sporocarp production in western Oregon Douglas-fir forests

Creator:: Hunt, Gary, 1945-
Abstract:: Total length and biomass of fungal mycelium in the soil of a young Douglas-fir stand in the central Oregon Coast Range were estimated over 27 months with the agar-film technique. In a second study, phenology and taxonomy of hypogeous (belowground) sporocarps were studied over 32 months in a nearby, young...

Rare, endangered, and recently extirpated mammals in Oregon

Creator:: Olterman, James Howard
Abstract:: This paper lists, and gives individual accounts of, those Oregon mammals that at some time have been referred to as being of a status other than common. Although rare and endangered wildlife species were listed on a national level in the United States, the large areas of land included in...

Habitat utilization by spotted owls in the West-Central Cascades of Oregon

Creator:: Forsman, Eric D.
Abstract:: Eight adult spotted owls (Strix occidentalis) on the west slope of the Cascade Range in Oregon were fitted with radio transmitters and observed for periods ranging from 271 to 383 days. Mean home range size for the owls was 1,177 ha (range = 920-1,376 ha). There was no significant difference...

The influence of behavior and water requirements on the distribution and habitat selection of the gray-tailed vole (Microtus canicaudus) with notes on Microtus townsendii

Creator:: Pearson, John Philip
Abstract:: Microtus canicaudus Miller, the gray-tailed vole, was studied in the field and laboratory in order to clarify aspects of the relationship of this species to its habitat. All trapping and sampling was done on permanent pasture land in the William L. Finley National Wildlife Refuge 12 miles south of Corvallis,...
