Ecology of woody riparian vegetation in tributaries of the Upper Grande Ronde River basin, Oregon

Creator:: Lytjen, Danna J.
Abstract:: Two studies on Catherine Creek and Meadow Creek of the Upper Grande Ronde River basin, quantified several physical and biotic influences on woody riparian community composition and structure. The Catherine Creek study examined the association of woody riparian species with elevational and geomorphic gradients. The Meadow Creek study examined the...

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...

Interactions of cattle and chinook salmon

Creator:: Ballard, Teena M.
Abstract:: Spring chinook salmon spawning occurs in late summer when it is common for cattle to be present in pastures that have streams where fish spawning occurs. This two-year study addressed three main objectives relative to behavioral interactions between cattle and spring chinook salmon during the spawning life history stage. These...

Investigations of soil morphology, hydrology, reduction-oxidation potentials, and stratigraphy on a selected hillslope in western Oregon

Creator:: Verble, Kathy K.
Abstract:: Hydric soils are defined through the hydric soil definition, and a means to identify hydric soils has been established through hydric soil criteria and Field Indicators of Hydric Soils in the U.S. However, the field indicators are a recent development that requires more research and testing to increase our knowledge...

Correlation between structural heterogeneity and arthropod biodiversity : implications for management of Pacific Northwest forests

Creator:: Madson, Stephanie Lee
Abstract:: The "old-growth controversy" in the Pacific Northwest recognized thinning as the primary silvicultural practice for land managers to produce wildlife habitat while continuing to produce timber. For the foreseeable future, forest stands will be harvested to produce forest gaps and a patchwork of trees of different ages. In order to...
