Thinning of young Douglas-fir forests has the potential to enhance structural diversity and improve habitat for wildlife. I examined the effects of thinning and thinning intensity on abundance and demographic characteristics of forest-floor small mammals in the Coast Range of Oregon 5 and 6 years after thinning had occurred. Thinning...
Habitat use and reproductive success by Merriam's wild turkey
(Meleagris gallopavo merriami) were studied in Wasco County, Oregon,
during 1981-82. This low density turkey population selectively used
forested cover types characterized by a variety of structural
features, species, and age classes. They avoided monotypic forested
cover types, used non-forested cover...
Thinning has the potential to increase structural diversity of managed forests for wildlife. During 1994-1996, I conducted experimental and observational studies using pitfall trapping to assess short-term and potential long-term effects of thinning on abundance and reproduction of forest-floor vertebrates in Douglas-fir (Pseudotsuga menzeisii) forests of the Oregon Coast Range....
The effects of beaver (Castor canadensis) on stream morphology, riparian zones, and coho salmon (Oncorhynchus kisutch) fry in Cape and Cummins Creeks, Oregon, were examined using stream surveys, vegetation transects, and coho salmon fry counts in 1987. The basin around Cape Creek has been extensively logged since the late 1940's....
Pygmy rabbits (Brachylagus idahoensis) in Oregon and Washington are a sagebrush (Artemisia tridentata spp.) obligate species of concern because of declining populations and extirpation from much of their range. Efforts are underway to establish a captive bred population of the Columbia Basin pygmy rabbit in Washington state for reintroduction into...
I evaluated the use of various wetlands by wintering ducks in
the Tulare Lake Basin (TLB), California, during October 1982 - April
1983 and September 1983 - March 1984. Aerial waterfowl counts of the
TLB were used to document spacial use patterns by ducks. Ground
surveys on evaporation ponds in...
The effects of disking, food plantings, and wheat plantings on a population of California quail (Lophortyx californicus) were studied from fall 1976 to spring 1978 on the E.E. Wilson Wildlife Area, Oregon. Twelve 16.2-ha study sites were established: 3 study sites for each treatment and 3 control sites. Disked areas,...
Despite the belief that fuels management, a form of prescribed fire that reduces accumulated fuels in commercially thinned forests, is necessary to restore forest 'health' in the Pacific Northwest, its effects on wildlife has received little attention in the scientific literature. Because fuels management is supported, funded, and implemented nationwide...
This study explores the lived experiences of first-year, rural, Oregon students in their initial entry to college. Through qualitative research involving one-on-one interviews with 10 participants, the author examines the transition of rural students into higher education, common experiences of rural students in their first term of college, and perceived...
Isolates of Trichoderma spp. collected from snap bean foliage were tested for inhibition of grey mold of snap beans caused by Botrytis cinerea. In a detached blossom-pod assay an isolate of Trichoderma hamatum reduced pod rot by 94% compared to the nontreated check. Control was comparable to that obtained with...
