Forest structure and regeneration in the Tsuga heterophylla - Abies amabilis transition zone, central Western Cascades, Oregon

Creator:: Stewart, Glenn H.
Abstract:: The dynamics of stands in the mid-elevation old-growth Douglas-fir (Pseudotsuga menziesii) forests of the central western Oregon Cascade Range were investigated using stand structure analysis. Trees with different growth rates were commonly present in the same stand, which resulted often in a weak correlation between tree diameter and age. Thus,...

The source area for coarse woody debris in small streams in western Oregon and Washington

Creator:: McDade, Mary Helen
Abstract:: Large organic debris has important biological and physical roles within the stream ecosystem. In order to determine the source area of large organic debris in streams, thirty-nine streams in the Cascade and Coast Ranges of Oregon and Washington were sampled. The distance from point-of-origin to channel was measured for thirty...

Responses of forest understory plants to burial by volcanic tephra from Mount St. Helens, Washington

Creator:: Antos, Joseph A.
Abstract:: The effects of burial by tephra (volcanic aerial ejecta) on forest understory plants were examined northeast of Mount St. Helens, Washington, in the area where the 18 May 1980 eruption deposited tephra but did not destroy canopy trees. At six sites along a tephra depth gradient from 2-15 cm, understory...

A fistful of Astragalus : phenotypic and genotypic basis of the most taxon rich species in the North American flora

Creator:: Knaus, Brian J.
Abstract:: The study of the infra-specific ranks (i.e., subspecies and variety) can be considered the study of the process of speciation. Astragalus lentiginosus Douglas ex Hooker (Fabaceae) is the most taxon rich species in the U.S. flora currently including 40 taxonomic varieties. These varieties were described using traditional taxonomic methods primarily...
