Storm runoff characteristics of various plant communities within the Oregon Range Validation Area

Creator:: Gaither, Ronald E.
Abstract:: A sediment production and infiltration study was conducted within the Oregon Range Validation Project Work Area in east-central Oregon during the summers of 1977 and 1978. High intensity rainfall was simulated by using a Rocky Mountain Infiltrometer. This sprinkler-type infiltrometer closely approximates conditions associated with natural rainfall. The basic ecological...

Use of range sites by pronghorns in south central Oregon

Creator:: Herrig, Daniel M.
Abstract:: Relative use by pronghorns (Antilocapra americana) of 16 range sites was studied during summer and fall of 1971 and 1972 on Hart Mountain National Antelope Refuge, an area of high desert rangeland in south central Oregon. A Relative Use Index was developed based upon 1533 observations of pronghorns located on...

Diet selection by conditioned and unconditioned goats in the sagebrush steppe of Eastern Oregon

Creator:: Richman, Lesley M.
Abstract:: This research examined the diets of angora goats on a sagebrush bunchgrass rangeland. Research objectives were to 1) determine the effects of a positive conditioning method on both mature and immature angora goats; and 2) to quantify plant selection and provide preliminary information as to the potential for using goats...

Soil engineering properties and vegetative characteristics for headwall slope stability analysis in the Oregon coast range

Creator:: Bransom, Mark
Abstract:: Six headwalls in the central Oregon coast range were selected for study of soil engineering properties and vegetativecharacteristics important for analysis of slope stability. The headwalls were considered representative of those which would be candidates for timber leave areas due to geomorphic and topographic features, including steepness of slope and...

The economics of western juniper management on ranches located in the John Day Ecological Province of north-central Oregon

Creator:: Aldrich, Gwendolyn A.
Abstract:: Western juniper (Juniperus occidentalis Hook) is a species of juniper native to arid regions of the Pacific Northwest. The western juniper tree has a number of competitive strategies that, in conjunction with an almost complete removal of fire from the ecosystem, have resulted in a significant expansion of its population...

Twenty-five years of grazing research at Meadow Creek in the Starkey Experimental Forest and Range

Creator:: Walburger, Kenric
Abstract:: Three studies were conducted to evaluate different grazing systems on mixed conifer rangelands in eastern Oregon, and photo points and aerial photography was used to determine effects of 25 years of cattle grazing on stream channel changes and vegetation responses. The first study was designed to determine if grazing treatment...

An opportunity cost approach to land preservation in the Oregon Coast Range

Creator:: Aliski, Leon David
Abstract:: This study estimates a range of opportunity costs associated with three land management alternatives for a site in the Oregon Coast Range. A 35,000 acre site was selected which includes a mix of federal and private land ownership and provides significant biological resources. The first alternative examines a plan for...

Establishment and growth of natural and planted conifers ten years after overstory thinning and vegetation control in 50-year-old Douglas-fir stands

Creator:: Nabel, Mark R.
Abstract:: Forest managers of public lands in western Oregon and Washington have become increasingly interested in creating additional conifer cohorts in young, even-aged, second-growth Douglas-fir stands. The purpose of our research was to assess the establishment, survival, and growth of naturally-regenerated and underplanted conifers 10-13 years after overstory thinning and understory...

Disturbance and landscape history as a reference for evaluating forest management effects at a regional scale : examples from the Coast Range of Oregon, USA

Creator:: Nonaka, Etsuko
Abstract:: History is an invaluable source of information to understand and evaluate management influences on contemporary ecosystems and landscapes. The first two chapters (Chapters 2 and 3) explored the concept of historical range of variability (HRV) in landscape structure and stand structure using a stochastic fire simulation model to simulate presettlement...
