Entrainment, transport, and deposition of large woody debris in streams : results from a series of flume experiments

Creator:: Braudrick, Christian A.
Abstract:: Although there has been extensive research on the geomorphic and ecologic role of large woody debris (LWD) in streams, the dynamics of LWD in streams are poorly known due to various measurement difficulties during floods. In this thesis I present the results of two flume experiments on the dynamics of...

A new index for describing the structural complexity of forests

Creator:: Zenner, Eric K.
Abstract:: Despite the critical ecological roles of structural features in forests, ecologically relevant quantitative measures of structure that allow comparisons among forest stands are still limited. A new index, the structural complexity index (SCI), was developed to characterize and compare the structural complexity of different forests. Point patterns of stem-mapped trees...

Interspecific carbon transfer in ectomycorrhizal tree species mixtures

Creator:: Simard, S. (Suzanne)
Abstract:: The overall goal of this study was to investigate influences of ectomycorrhizae (EM) and interspecific carbon transfer on seedling performance in species mixtures. The objectives were to: (I) determine the potential for EM to link paper birch and Douglas-fir, (ii) quantify gross and net interspecific carbon transfer, and (iii) evaluate...

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...

Tree seedling establishment on heterogenous microsites in Douglas-fir forest canopy gaps

Creator:: Gray, Andrew N.
Abstract:: Tree seedling establishment and growth were studied in experimental canopy gaps to determine the effect of structural and environmental heterogeneity on species dynamics within mature and old-growth Douglas-fir forests in the Cascades of central Oregon and southern Washington. Factors examined included forest age, gap size, within-gap position. substrate, year of...

Estimating large woody debris recruitment from adjacent riparian areas

Creator:: Minor, Kathleen P.
Abstract:: Large woody debris recruitment to streams from adjacent riparian forests influences stream channel morphology, sediment routing, and fish habitat. A mathematical model was developed to 1) determine whether the trees in a stand adjacent to a stream, upon falling, would provide large woody debris of a specified size to the...

Ecology of forest floor bryophytes in Pseudotsuga menziesii-Tsuga heterophylla stands of western Oregon : implications for forest management

Creator:: Rambo, Thomas Roy
Abstract:: Species richness and abundance of forest floor bryophytes, including epiphytes from incorporated litterfall, were assessed at two sites in western Oregon. Bryophyte diversity, abundance, and community composition were compared between sites, and between young forest stands ([approximately] 55 yrs.) and old-growth stands (400+ yrs.) within each site. Relationships of stand...

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...
