Historical changes in anadromous fish habitat in the Upper Grande Ronde River, Oregon, 1941-1990

Creator:: McIntosh, Bruce A.
Abstract:: The U.S. Bureau of Fisheries (now National Marine Fisheries Service) conducted stream habitat surveys in the Upper Grande Ronde River Basin in 1941. This survey was part of an extensive inventory of stream habitat conditions for anadromous salmonids (Oncorhynchus spp.) throughout the Columbia River Basin. The survey systematically inventoried 158...

The ecology of Devil's club (Oplopanax horridum (J.E. Smith) Miq.) in western Oregon

Creator:: Roorbach, Ashley H.
Abstract:: Devil's club (Oplopanax horridum (J. E. Smith) Miq.) is an indigenous shrub of the Pacific Northwest, often found in the Tsuga heterophylla (western hemlock)/Devil' s club association in western Oregon. In the same family as ginseng, Devil's club is gaining attention for its medicinal properties. While traditional uses of Devil's...

Limits on aboveground net primary production, leaf area, and biomass in vegetational zones of the Pacific Northwest

Creator:: Gholz, Henry L.
Abstract:: Samples of mature vegetation from 8 of 12 major vegetational zones in Oregon and Washington, representing about 80% of the area of the two states, were studied along a latitudinal transect from the Pacific Coast to the east slopes of the Cascade Mountains. Six stands were in forest zones, one...

Early survival and growth response of five species of Pinus to plant competition and aspect in southwest Oregon and northeast Mexico

Creator:: Capo-Arteaga, Miguel A.
Abstract:: The effect of forest shrub vegetation on soil moisture, temperatures evaporation potentials and the survivals growth and bud activity of five species of Pinus was studied on planting sites placed on opposite exposures on two locations in southwest Oregon and northeast Mexico. Treatments applied were: Manual slashing; Manual slashing plus...

Fire history, fire regimes, and development of forest structure in the central western Oregon Cascades

Creator:: Weisberg, Peter J.
Abstract:: Fire history and fire regimes were reconstructed for a 450 km² area in the central western Oregon Cascades, using tree-ring analysis of fire scars and tree origin years at 137 sampled clearcuts. I described temporal patterns of fire frequency, severity, and size, and interpreted topographic influences on fire frequency and...

A characterization of unmanaged riparian overstories in the central Oregon Coast Range

Creator:: Nierenberg, Tara R.
Abstract:: Riparian areas that can be used as reference sites on which to base goals of vegetation restoration have not been documented in the Oregon Coast Range. I examined the composition and distribution of unmanaged riparian overstories in the central Oregon Coast Range along nine streams which have experienced minimal disturbance...

Structure and development of old-growth Douglas-fir in central western Oregon

Creator:: Poage, Nathan Jeremy
Abstract:: The tree species and size structure of 9l old-growth forests dominated by Douglas-fir in central western Oregon was characterized using complete inventories of all trees larger than 20cm dbh over a mean area of 17.1ha at each site. Douglas-fir accounted for over 75% of the total average basal area (39.1...

Comparison of stand development of a deciduous-dominated riparian forest and a coniferous-dominated riparian forest in the Oregon Coast Range

Creator:: Poage, Nathan Jeremy
Abstract:: Riparian forests in the central Oregon Coast Range vary along a coniferous-deciduous compositional continuum. Variations in structure and composition affect water quality, fish and wildlife, biodiversity, timber, and aesthetics. A retrospective approach was taken in this study in order to understand and compare the structure, pattern, and history of an...

Effects of vegetation and disturbance on fungal communities in the western Cascades of Oregon

Creator:: Kageyama, Stacie Ann, 1967-
Abstract:: The use of high throughput molecular methods that allow for the study of bacterial communities in environmental samples is commonplace in microbial ecology. Until recently, fungal community ecology has focused on isolation, collection of sporocarps, or collection of ectomycorrhizal roots. The techniques used to extract and amplify DNA from environmental...

Ecology of Craterellus tubaeformis in western Oregon

Creator:: Trappe, Matthew James
Abstract:: Craterellus tubaeformis is a small to medium-sized forest mushroom that is fairly common in the Douglas-fir/western hemlock forests of the Pacific Northwestern United States and is most often associated with decayed coarse woody debris. In this study, the mycorrhizae of Craterellus tubaeformis in western Oregon is identified by DNA analysis...
