Snowbrush, Ceanothus velutinus Dougl., its ecology and role in forest regeneration in the Oregon Cascades

Creator:: Zavitkovski, J.
Abstract:: The ecological and silvicultural importance of snowbrush, Ceanothus velutinus, in the areas west of the summit of the Oregon Cascades was studied. Particular attention has been given its nitrogen- fixing ability under both field and greenhouse conditions. On west slopes of the Oregon Cascades snowbrush occurs above 2, 500 feet...

Symbiotic nitrogen fixation by Ceanothus species

Creator:: Wollum, Arthur George
Abstract:: The primary intent of this study was to clarify the role of the endophyte in the Ceanothus symbiosis. A technique utilizing a 20 percent solution of H₂O₂ was developed which allowed the isolation of a Streptomyces sp. from the root nodules of some Ceanothus species. Further characterization suggested that the...

A simulation model of wood dynamics in Pacific Northwest streams

Creator:: Meleason, Mark Alan
Abstract:: Conceptually, the dynamics of wood in streams can be viewed in terms of input and in-channel processes. Input processes are associated with both the riparian (tree fall, bank cutting, windthrow) and upslope forests (mass failures). In-channel processes include log breakage, movement, and decomposition. A mechanistic view of these processes is...

Spatial and temporal patterns of windthrow in the Bull Run Watershed, Oregon

Creator:: Sinton, Diana Stuart
Abstract:: Throughout the 20th century, windthrow has affected forests in the Bull Run watershed, a 26,500 ha basin that is the principal water source for the city of Portland, Oregon. Windthrow from storms in 1973 and 1983 was mapped into a geographic information system (GIS) and compared to a 1931 windthrow...

Response of avian communities to herbicide-induced vegetation changes, western Oregon

Creator:: Morrison, Michael L.
Abstract:: The relationships between avian community structure and herbicide modification of vegetation were analyzed on early-growth clearcuts in western Oregon that had received phenoxy herbicide treatment 1 or 4 years previously. Only minor effects of herbicide treatment were evident 1-year after spraying, except for red adler (Alnus rubra), which still exhibited...
