In this paper the extent of the steep slope brush conversion problem will be estimated. Potential solutions and development should be commensurable with the extent of the problem. The state-of-the-art of steep slope site preparation and conversion will
be described. Feasible alternatives to these limited options will be developed.
Recently, the big sagebrush taxa has been split into subspecies
and forms. Four habitat types related to subspecies of big sagebrush
were studied in Eastern Oregon. Response of understory vegetation was
measured following three range improvement techniques implemented on
the four habitat types for several ages of treatment. Crown cover,...
Much forest land in Western Oregon has been lost to production due to brush competition. As the demand for forest products increases,
more attention should be paid to the reclamation of these unproductive lands.
Chemical herbicides have been proven an efficient tool for brush control from the physiological viewpoint. This...
Aerial application of fosamine ammonium or glyphosate at moderate rates was not adequate for controlling understory brush before final harvesting of mature Douglas-fir (Pseudotsuga menziesii) stands or for reducing vigor of post-harvest sprouting. Symptoms of herbicide injury were those associated with low application rates, suggesting that the canopy intercepted too...
Arctostanhylos viscida is a broad-leaved, evergreen, sclerophylbus shrub which grows in northern California and the Siskiyou
Mountain region of southwest Oregon. After site disturbance, A. viscida competes with conifer regeneration, and may dominate a site for ninety years. This study examined the rate at which full site occupancy occurs in...
