This report presents information concerning the water and related land resources of the Powder Drainage Basin. Its purpose is (1) to provide information on the past and present uses of water and related land resources; (2) to supply the production data from the use of these resources; (3) to assess...
Fintrol-5 was experimentally tested in six isolated gold dredge ponds in Sumpter Valley. The tests revealed all coarse fish in treated ponds were killed in a period varying between 7 hours and 144 hours; toxic water subbing from treated ponds would kill fish in downstream ponds if water table dillution...
Many resource management controversies indicate
disagreement about the possible intended and unintended effects
of management actions on ecosystems. Researchers have
documented a variety of negative effects on specific ecosystems, e.
g. the degradation of salmonid habitat due to mass wasting
(Hagans et al. 1986). While the effects of some management...
A stand level model, PREscription generator under Multiple Objectives (PREMO) was built to generate prescriptions that address multiple objectives for management of the forests of the Applegate River Watershed. PREMO is a part of the landscape model of the Applegate River Watershed Forest Simulation Project and generates prescription choices for...
Two research questions are posed: (1) How have ecosystem conditions changed through time in southwestern Oregon? (2) How have culture-driven and climate-driven processes contributed to ecosystem change in southwestern Oregon? A brief introduction to the Little River study area is followed by a cultural and ecological history of the watershed....
Growing emphasis on ecosystem and landscape-level forest management across North America has spurred an examination of alternative management strategies which focus on emulating dynamic natural disturbance processes, particularly those associated with forest fire regimes. This topic is the cornerstone of research in the Blue River Landscape Study (BRLS) taking place...
This report presents information concerning the water and related land resources of the Middle Willamette River Basin and is the result of a cooperative study by the U. S. Department of Agriculture and the State Water Resources Board of Oregon.
The State Water Resources Board of Oregon is making a...
Watershed management is widely recognized as an important component of healthy ecosystems and its success depends on cultivating the good will, stewardship values, and participation of citizens. Because much of the streamside land in Oregon is in private ownership activities on public lands will not be enough to protect salmon...
