Elevation, thermal environment, and stream temperatures on headwater streams in northeastern Oregon

Creator:: Meays, Cynthia L.
Abstract:: A case study examining the relationship between stream temperatures and the thermal environment through which streams flow was conducted on the headwaters of 4 tributaries of the Burnt River (Barney, Elk, Greenhorn, and Stevens Creeks) in northeastern Oregon during July through August 1998 and 1999. Barney Creek and Stevens Creek...

Characteristics of forests at spotted owl nest sites in the Pacific Northwest

Creator:: Hershey, Kit
Abstract:: This study describes the composition and structure of forests within the immediate vicinity of Northern spotted owl (Strix occidentalis caurina) nest sites in the Klamath, Coast, and Cascade provinces of western Oregon and the Olympic province, Washington. I compared forest stand data collected at 105 nest sites with data from...

Similarities in understory vegetation composition between unthinned, thinned and old-growth Douglas fir stands in western Oregon

Creator:: Mayrsohn, Cheryl
Abstract:: Forest stands were studied to determine if old-growth forest structure could be mimicked in younger stands via overstory manipulation. Cover and species composition of understory plants were systematically sampled in sixteen thinned second-growth stands and sixteen adjacent unthinned second-growth Douglas fir (Pseudotsuga menziesii (Mirabel) Franco.) stands. The stands were thinned...

Autecological studies of two annual herbs, Senecio sylvaticus and Epilobium paniculatum : effects of biotic and abiotic factors

Creator:: Geyer, Melora Arnason
Abstract:: I used greenhouse and field studies to investigate how intraspecific and interspecific competition, soil disturbance, and fertilization affect the biomass and reproductive output of Senecio sylvaticus and Epilobium paniculatum, common winter annuals which invade and dominate western Cascades forests during the first two seasons after clearcutting and slashburning. Field work...

Influence of light on the growth of advance regeneration in the understory of Douglas-fir dominated forests in western Oregon

Creator:: Deisenhofer, Florian
Abstract:: The growth potential of Douglas-fir, grand fir and western hemlock advance regeneration in the forest understory of Douglas-fir-dominated forests was investigated to detennine the feasibility of selection cutting systems in northwest Oregon. This study compared the growth of Douglas-fir, grand fir and western hemlock advance regeneration along a light gradient...

Stocking and growth of noble fir in the Cascade Mountains of Oregon and Washington

Creator:: Thomas, Theodore Bruce
Abstract:: Stocking levels and height growth rates of noble fir and associated species were measured on 51 clearcut study areas within the Pacific silver fir zone of the Oregon and Washington Cascades. Clearcut study areas were approximately 20 years old and had either planted noble fir or natural regeneration of noble...

Habitat selection by American martens (Martes americana) in coastal northwestern California

Creator:: Slauson, Keith M.
Abstract:: The Humboldt marten, Martes americana humboldtensis, has undergone a dramatic decline throughout its historical distribution in coastal Northwestern California. There is currently only one known population occupying an area occurring in <5% of the historical distribution of the subspecies. Conservation and management efforts to benefit this population are hampered by...

Generation of an animation interface for ORGANON

Creator:: Hanus, Mark L.
Abstract:: The focusing of public attention on the practices of forest managers has resulted in the need for new tools to help explain the results of these practices. The traditional tools of tables and graphs of numerical values require a significant investment in learning the forestry profession. Once the investment is...

Distribution and growth of advance Douglas-fir regeneration in commercially thinned stands in the Oregon Coast Range

Creator:: Beer, Louis W.
Abstract:: This study examined the abundance, size, growth, and age of advance regeneration Douglas-fir, beneath an eighty year-old overstory at a single site on plots subjected to different overstory thinning treatments. Treatments consisted of keeping overstory basal area within upper and lower limits for periods of 12-17 years which, depending upon...

Habitat relationships of birds and young-growth Douglas-fir in northwestern California

Creator:: Marcot, Bruce G.
Abstract:: Ninety-one species of birds were surveyed in grass/forb, early and late shrub/sapling, pole, and medium sawtimber stages of young-growth Douglas-fir in northwestern California; patterns of bird distribution and abundance were related to habitat conditions and even-age silvicultural treatments. Seven species (band-tailed pigeon, western wood pewee, dusky flycatcher, western bluebird, fox...
