Small-mammal herpetofauna abundance in riparian and upslope areas of five forest conditions

Creator:: Gomez, Douglas M.
Abstract:: I compared species composition and relative abundance of'small mammals and herpetofauna between riparian and upslope habitats among 5 forest types. Riparian- and upslope- associated species were identified based on capture frequency. Small mammal species richness was similar between stream and upslope habitats and among the 5 forest types. There were...

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...

Spatial pattern and dynamics of hardwood patches in the Coast Range of Oregon, 1939-1993

Creator:: Hess, Rebecca Susan
Abstract:: Analysis of the long-term spatial pattern and dynamics of hardwood patches in the Coast Range of Oregon provides numerous ecological insights. Natural and anthropogenic disturbances have contributed to the development of a patchy mosaic of vegetation types in the area. Some hardwood patches in the Coast Range may be the...

Similarities in understory vegetation composition between unthinned, thinned and old-growth Douglas fir stands in western Oregon

Creator:: Mayrsohn, Cheryl
Abstract:: Forest stands were studied to determine if old-growth forest structure could be mimicked in younger stands via overstory manipulation. Cover and species composition of understory plants were systematically sampled in sixteen thinned second-growth stands and sixteen adjacent unthinned second-growth Douglas fir (Pseudotsuga menziesii (Mirabel) Franco.) stands. The stands were thinned...

The clonal development of vine maple during Douglas-fir stand development in the Coast Range of Oregon

Creator:: O'Dea, Mary E.
Abstract:: Natural Douglas-fir stand development is the result of many types of disturbance, both natural and management induced. The magnitude and timing of these disturbances have profound effects on the structure and composition of both the overstory and understory plant communities. Vine maple responds to disturbance by basal sprouting, layering, producing...

Habitat classification and characteristics of small mammal and amphibian communities in beaver-pond habitats of the Oregon Coast Range

Creator:: Suzuki, Nobuya
Abstract:: During 1988-1989, stream habitat variables were compared between beaver-dam sites and unoccupied-stream sites to identify variables that may have been important for beaver (Castor canadensis) in selecting dam sites in the streams of the Drift Creek basin, Lincoln County, Oregon. Increasing valley floor width and grass/sedge cover and decreasing stream...

Preliminary reconstruction and analysis of change in forest stand age classes of the Oregon Coast Range from 1850 to 1940

Creator:: Teensma, Peter Dominic Adrian, 1956-, Rienstra, John T., and Yeiter, Mark A.
Abstract:: Fire and other catastrophic disturbance events in the Douglas-fir forests of the Oregon Coast Range have been significant in determining the distribution of stand age classes and, hence, habitat. Except for the past half century, knowledge of fire in the region has largely been local and anecdotal. The Douglas-fir forests...

Activity of bats in thinned, unthinned, and old-growth forests in the Oregon Coast Range

Creator:: Humes, Marcia Lynn
Abstract:: Ten species of bats occur in the Oregon Coast Range and are hypothesized to be associated with late-successional forests. The development of characteristics of late-successional forests in young forest stands can be accelerated through silvicultural practices such as thinning I examined the effects of thinning on the use of forests...

Spatial and temporal patterns of fire in the forests of the central Oregon Coast Range

Creator:: Impara, Peter C.
Abstract:: Fire history and fire regime were interpreted from tree ring analysis of 4320 stumps at 178 sites in a 25 by 55 km area in the central Oregon Coast Range. A total of 27 fire episodes were identified in a 516 year period, with sizes estimated at 18 to 544...

Terrestrial amphibian abundance and species richness in headwater riparian buffer strips, Oregon Coast Range

Creator:: Vesely, David G. (David Gordon), 1954-
Abstract:: I examined the abundance and habitat associations of terrestrial amphibian species and the species richness of terrestrial amphibian communities in riparian buffer strips, clearcuts, and unmanaged riparian forests. The study was conducted in the western hemlock (Tsuga heteropliylla) vegetation zone of the northern and central Oregon Coast Range. Data were...
