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...

Patterns of chronic wind mortality in a small, old-growth Pseudotsuga menziesii forest in the western Cascades, Oregon

Creator:: Littlefield, Sam, 1980-
Abstract:: Windthrow has been studied extensively as a cause of mortality and as a landscape disturbance agent in temperate forests throughout the United States. The effects of windthrow mortality on stand species composition and structure, forest regeneration and seral development have been well described at the site (e.g. single gap) and...

Social, Ecological, and Economic Outcomes Associated with Stewardship Forestry in the Siuslaw Watershed

Creator:: Colón–Almodóvar, Yamilette M.
Abstract:: In 1994, with the approval of the Northwest Forest Plan, the livelihood of individuals in the surrounding communities of the Siuslaw National Forest and Siuslaw Watershed were further impacted by already diminished traditional timber practices. In 2003, the United States Forest Service developed an innovative program, stewardship contracting, aimed at...

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...

A per-segment approach to improving aspen mapping from remote sensing imagery and its implications at different scales

Creator:: Heyman, Ofer
Abstract:: A per-segment classification system was developed to map aspen (Populus tremuloides) stands on Winter Ridge in central Oregon from remote sensing imagery. A 1-meter color infrared (CIR) image was segmented based on its hue and saturation values to generate aspen "candidates", which were then classified to show aspen coverage according...

The effects of land use changes on forest fires in major islands of Indonesia

Creator:: Lumban-Tobing, Pago L.
Abstract:: The study examines the effect of forest clearance on fire occurrences in major islands of Indonesia, namely: Borneo, Sumatra, Sulawesi and Irian Jaya. The working hypothesis of the study is that forest clearing is a necessary predecessor for extensive fires to occur. The study is designed to test the idea...

Structural and functional comparison of human-impacted and natural forest landscapes in the western Cascades of Oregon

Creator:: Pennington, Deana D.
Abstract:: This study compared effects of human and natural wildfire disturbance on age class distribution and associated ecosystem properties of forests in a 15,670 km2 area of the western Cascades of Oregon. The study site is characterized by three forest use types: low elevation, intensively harvested private industrial lands; mid elevation...

Oregon man-forest relationships and the 1971 Forest Practices Act

Creator:: Sullivan, Michael J.
Abstract:: Since the inception of white settlement, Oregon man-forest relationships have progressively matured. The 1971 Forest Practices Act is the culmination to date of increasing societal concern for the protection of the forest environment and the conservation of its resources. The Act has resulted in an increased employment of forest practices...

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...

Biomass and community structure of sporocarps formed by hypogeous ectomycorrhizal fungi within selected forest habitats of the H. J. Andrews Experimental Forest, Oregon

Creator:: Luoma, Daniel L.
Abstract:: This study characterizes the production of hypogeous sporocarps (broadly referred to as truffles) by ectomycorrhizal fungi within Douglas-fir dominated forests that are considered typical of those found on the west slopes of the central Cascade mountains in Oregon. Three aspects of sporocarp production are addressed: 1) the distribution of total...
