One of the goals of ecosystem management is to integrate management of many species and processes across a range of temporal and spatial scales. I investigated the relationship between small mammals and amphibians at 3 spatial scales. My objective
was to identify, habitat associations of forest floor vertebrates at the...
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...
Human-induced fragmentation of forests is increasing, yet the consequences of these landscape changes to vertebrate communities are poorly understood. Despite progress in our understanding of how bird communities
respond to forest fragmentation caused by agricultural or urban development, we have little understanding of these dynamics in landscapes undergoing intensive forest...
To quantify the distribution and abundance of the riparian-associated vertebrate community, I surveyed streams in four basins in the Oregon Coast Range, 1992-1994. I observed mostly birds with fewer observations of mammals. Belted Kingfishers (Ceryle alcyon), American Dippers (Cinclus mexicanus), Great Blue Herons (Ardea herodias), and Mallards (Anus plalyrhynchos) comprised...
Tracer-derived estimates of hydraulic resistance and transient hydraulic
storage were related to measures of pool volume and channel morphometric
variability in small streams of the Oregon coast, U.S.A. Fourteen
100 m study reaches in 3 streams were selected to compare channel
and hydraulic characteristics in streams representing a time series...
This study is part of the effort to quantify sediment budgets and understand the geomorphic evolution of steep mountains where debris flows are the dominant agent of upland erosion. Observations indicate that headwater basins in the Oregon Coast Range (OCR) can store a large amount of sediment, mostly from debris...

The Early Oligocene Oregon Coast Range Intrusions (OCRI) consist of gabbroic rocks and lesser alkalic intrusive bodies that were emplaced in marine sedimentary units and volcanic sequences within a Tertiary Cascadia forearc basin. The alkalic intrusions include nepheline syenite, camptonite, and alkaline basalt. The gabbros occur as dikes and differentiated...
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...
