The spatial distribution of beaver (Castor canadensis) impoundments and effects on plant community structure in the lower Alsea drainage of the Oregon Coast Range

Creator:

Perkins, Thaïs Erbel

Abstract:

Stream systems in the Pacific Northwest have come to be understood in the absence of beaver (Castor canadensis). To understand the effect of beaver upon riparian plant communities, four basins in the lower Alsea drainage were examined to determine the effect of beaver and their impoundments on streamside herbaceous/shrub and...

Beaver (Castor canadensis) Impoundments and Effects on Plant Community Structure in the Lower Alsea
Effects of beaver on streams, streamside habitat, and coho salmon fry populations in two coastal Oregon streams

Creator:

Bruner, Karen L.

Abstract:

The effects of beaver (Castor canadensis) on stream morphology, riparian zones, and coho salmon (Oncorhynchus kisutch) fry in Cape and Cummins Creeks, Oregon, were examined using stream surveys, vegetation transects, and coho salmon fry counts in 1987. The basin around Cape Creek has been extensively logged since the late 1940's....
