Use of a rainfall-runoff model for simulating effects of forest management on streamflow in the east fork Lobster Creek Basin, Oregon

Creator:: Nakama, Lenore Y., Risley, John C., and United States. Bureau of Land Management, Geological Survey
Abstract:: The report describes the results of model calibration and validation, and evaluates the extent to which runoff response to timber harvesting and increased road densities in East Fork Lobster Creek Basin can be simulated, using Precipitation-Runoff Modeling System (PRMS), a deterministic, destributed-parameter-modeling system.

A preliminary investigation of the spotted owl in Oregon

Creator:: Forsman, Eric D.
Abstract:: Between 1970 and 1974, data were collected on the distribution and biology of the spotted owl (Strix occidentalis) in Oregon. One-hundred and sixteen pairs and seven single birds were located. Spotted owls occurred throughout the mountains of western Oregon and on the east slope of the Cascade Range at least...

Mountain pine beetle infestation potential for the Plains Ranger District, Lolo National Forest

Creator:: Gibson, Kenneth E., United States. Forest Service. Northern Region. Forest Insect and Disease Management, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: This report contains an overview of the present mountain pine beetle infestation in lodgepole pine stands on Federal, State, and private lands on the Plains Ranger District. Particular emphasis is placed on the potential for beetle mortality in the Thompson River drainage where recent ground surveys show more than 21...

Natural mortality in a Douglas-fir tussock moth infestation in Idaho, 1974

Creator:: Tunnock, Scott, McGregor, Mark D., Lood, Rudolph C., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mortality from various causes was recorded in a Douglas-fir tussock moth, Orgyia pseudotsugata McD., outbreak southeast of Coeur d'Alene, Idaho, in 1974. Observations began June 27 when about 50 percent of the larvae were second instars and continued until pupation. Within a 35-day period, there was a 93 percent average...

Geographic variation in central Oregon ponderosa pine (Pinus ponderosa Laws.) : seed germination; seed, wing, and cone morphology; seed color

Creator:: Weber, John C., 1948-
Abstract:: Geographic variation was investigated among 225 locations from five geographically disjunct regions in central Oregon. Characters included: germination speed and uniformity in two test environments differing in stratification period and incubation temperature; weight, three dimensions and three 'angles' of seeds; weight and three dimensions of wings; cone length and scale...
