Abstract:: In western Oregon, hardwood trees occupy 20% of the timberland but account for less than 1% of the timber harvest. Information about how to manage them effectively is limited. The objective of this study was to examine: 1) effect of thinning on tree growth, plant moisture stress, and crown cover...

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...

Creator:: Carlton, Gary C.
Abstract:: Red alder (Alnus rubra Bong.) is a fast-growing pioneer species that colonizes disturbed forest sites west of the Cascade Mountains in the Pacific Northwest. Streambottoms, toe slopes, and mass movement of surface soils have historically provided the scarification and soil moisture necessary for successful regeneration of red alder. During the...

Creator:: Hart, Stephanie K.
Abstract:: Riparian zone vegetation can influence terrestrial and aquatic food webs through variations in the amounts, timing, and nutritional content of leaf and other litter inputs. Differences in vegetation composition and density, as well as riparian topography, may modulate the strength and quality of these inputs. Changes in inputs to small...

Creator:: Giordano, Peter A.
Abstract:: The amount and quality of competition among individuals in developing plant communities is an important factor determining community structure, composition and development. In perennial plant communities, this competition is reflected by shifts in carbon allocation among plant parts and can result in long-term structural differences between neighboring individuals. This study...

Creator:: Matkins, Joselin
Abstract:: I examined factors regulating decomposition rates of red alder (Alnus rubra)) and Douglas-fir (Pseudotsuga menziesii) leaf litter in Coast Range riparian areas in western Oregon. Overall, this study was designed to examine the influence that leaf litter quality characteristics and decomposition site treatment have on decomposition rates, to provide a...
