Patterns of hillslope and channel recovery following disturbances in steep, forested basins

Creator:: Madej, Mary Ann
Abstract:: Geomorphic response to watershed disturbances commonly results in alterations of landforms. Subsequent geomorphic recovery is dependent on the ability of flows to entrain, transport, and organize inorganic and organic material on hillslopes and in channels. This research analyzed changes in sediment production, channel structure, and channel organization following disturbances in...

Biophysical spectral regionalization of the Pacific Northwest using Advanced Very High Resolution Radiometer Imagery

Creator:: Greninger, Jon F.
Abstract:: Satellite imagery has become an efficient and time effective tool that may aid in the development of regional terrestrial and aquatic resource management schemes. A methodology utilizing National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) imagery, 1.1 kilometer spatial resolution at nadir, was developed for delineating...

Spatial changes in alpine treeline vegetation patterns along hiking trails in Glacier National Park, Montana

Creator:: Klasner, Frederick L.
Abstract:: Sequential aerial photography was used to identify effects of hiking trails on the spatial distribution of subalpine fir (Abies lasiocarpa) habitat at alpine treeline. Vegetation change over a 46 year period was compared along trails relative to areas without trails, at five study sites in the McDonald Creek drainage of...

Storm-induced mass wasting in forested areas: conditions and characteristics for three Western Oregon study sites

Creator:: Robben, Joshua L.
Abstract:: Much of the rich forestlands of Oregon are subject to frequent mass wasting events, resulting in severe environmental and economic damages. Extensive research has shown that this landslide hazard is often exacerbated by many management activities. Following a severe storm event which triggered thousands of landslides, the Oregon Department of...

Large woody debris and geomorphic influences on stream morphology within the transitional climatic zone of the northern Oregon Cascades

Creator:: Brunfelt, Michael Richard
Abstract:: Loss of anadromous and resident fish habitat has become an increasing concern in the Columbia River Basin. Forest management practices play a role in the health of headwater stream habitat. The effects of instream large woody debris is known to effect stream morphology and fish habitat. This paper considers effects...

Spatial and temporal patterns of fire in the forests of the central Oregon Coast Range

Creator:: Impara, Peter C.
Abstract:: Fire history and fire regime were interpreted from tree ring analysis of 4320 stumps at 178 sites in a 25 by 55 km area in the central Oregon Coast Range. A total of 27 fire episodes were identified in a 516 year period, with sizes estimated at 18 to 544...

River restoration: active vs. passive restoration efforts, Alder Creek example

Creator:: Keating, Stephen
Abstract:: The practice of river and stream restoration has increased with heightened environmental concerns and awareness. Many of these projects use structural modifications in an attempt to mimic natural landscapes. These structural modifications represent an active approach to river and stream restoration. Active restoration projects are well funded and extensively constructed....

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...

Geographic Information System model rating old-growth stand significance on the Olympic National Forest

Creator:: Wettengel, William M.
Abstract:: With increased attention being focused on the remaining old-growth forest resource in the Pacific Northwest a way to ecologically rate forest stands is needed to assist the U.S. Forest Service in its management decisions. A Geographic Information System (GIS) model was developed to rate old-growth stands in a 49,500 acre...

Forestry herbicide use on private forest lands in Lincoln and Benton County Oregon, 1991-1994

Creator:: Godino, John Alessandro
Abstract:: The use of phenoxy herbicides is an established practice in industrial forestry, particularly in the Pacific Northwest. Forestry herbicide use in this region has often been controversial. To better understand the spatial patterns of herbicide use and the potential for human health and environmental impacts, a landscape level perspective is...
