Watershed-scale vegetation patterns in a late-successional forest landscape in the Oregon Coast Range

Creator:: Wimberly, Michael C.
Abstract:: Knowledge about vegetation patterns and ecological processes in unmanaged, late-successional watersheds is needed to provide a foundation for forest management strategies aimed at conserving native biodiversity. I examined influences of environmental variability and disturbance history on forest structure and composition in the Cummins Creek Wilderness, located on the central Oregon...

A plant association classification for McDonald-Dunn Forest

Creator:: Hubbard, Connie J.
Abstract:: The purpose of this study was to develop a plant association classification for the mature coniferous forests of the McDonald and Paul M. Dunn Research Forests. A secondary objective was to quantify diversity within the plant associations. This Forest is approximately 11,000 acres and is located 6 miles to the...

The effect of riparian buffer strips on salmonberry (Rubus spectabilis) community structure in alder stands of the Oregon Coast Range

Creator:: Froyd, Cynthia A.
Abstract:: Salmonberry community structure was examined in alder-dominated riparian buffer strips in the Oregon Coast Range. Salmonberry growing on slopes was found to respond differently, to both characteristics of the buffer strips and to environmental factors, than salmonberry growing on terraces. Salmonberry, as measured by total height, number of ramets or...

A sustainable resource development plan framework for the Neskonlith Indian Band, British Columbia

Creator:: Mackasey, J. Patrick
Abstract:: A sustainable resource development plan framework was prepared for the Neskonlith Indian Band, who are located in the interior of British Columbia, Canada. The framework intends to address issues involving; integrated resource management, traditional native land management, ecosystem management, and community-based resource management. A soft systems (Wilson & Morren, 1990)...

Competitive interactions between Douglas-fir or ponderosa pine and whiteleaf manzanita

Creator:: White, Diane E.
Abstract:: Juvenile Douglas-fir, ponderosa pine, and whiteleaf manzanita growth in southwest Oregon varied with density of co-developing manzanita and presence of herbaceous cover. Plant xylem pressure potential and stomatal conductance of each species was responsive to competition-induced depletion of soil water. Rates varied among species. The best correlations with growth usually...

Influence of light on the growth of advance regeneration in the understory of Douglas-fir dominated forests in western Oregon

Creator:: Deisenhofer, Florian
Abstract:: The growth potential of Douglas-fir, grand fir and western hemlock advance regeneration in the forest understory of Douglas-fir-dominated forests was investigated to detennine the feasibility of selection cutting systems in northwest Oregon. This study compared the growth of Douglas-fir, grand fir and western hemlock advance regeneration along a light gradient...

Songbird communities in burned and logged stands with variable tree retention in the Canadian Rocky Mountains

Creator:: Stuart-Smith, A. Kari
Abstract:: By emulating natural disturbances such as wildfire, managers hope to maintain biodiversity in managed forests. Leaving residual (live) trees in harvested areas is key to this strategy. However, the effectiveness of this approach is unknown. I surveyed songbirds in 176 stands in the Rocky Mountains of southeastern British Columbia, Canada,...

Growth growing-stock relationships in young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Sales Luis, Jaime Fernando
Abstract:: In the thinning theory, the hypothesis that the stand growth is unaffected by the density over a broad range of densities is generally accepted today. In this study three different measures of stand density were used in basal area growth and volume growth multiple regressions in even-aged managed stands, searching...

Stand level silvicultural optimization utilizing a late-seral index constraint

Creator:: Semeliss, Wade Alan
Abstract:: A dynamic programming algorithm (MS PATH) was used to develop a stand level optimization model, FPS Optimizer. The model incorporates a late-seral constraint on the profit maximizing objective function utilizing a four-descriptor structural index as a proxy. This index, the 'Old-Growth Index', rates the late-seral structural quality of a given...

Structural development of late successional forests in the central Oregon Coast Range : abundance, dispersal, and growth of western hemlock (Tsuga heterophylla) regeneration

Creator:: Schrader, Barbara A.
Abstract:: Patterns of western hemlock regeneration were studied in relation to forest structural development and environment in the Oregon Coast Range. Density of western hemlock seedlings was examined across the climatic gradient from cool, moist coastal areas to the seasonally hot and dry Willamette Valley Margin. Seedling densities were most strongly...
