Habitat use and densities of cavity-nesting birds in the Oregon Coast Range

Creator:

Nelson, S. Kim

Abstract:

I studied abundance patterns and habitat use of eight cavitynesting bird species in the Coast Ranges of Western Oregon during the spring and summer of 1985 and 1986. Three age classes of unmanaged Douglas-fir (Pseudotsuga menziesii) stands were selected for study: young (40-80 yrs), mature (80-200 yrs), and old-growth (>200...

Abundance, habitat association, and foraging ecology of American dippers and other riparian-associated wildlife in the Oregon Coast Range

Creator:

Loegering, John P., 1964-

Abstract:

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...

Relative abundance and habitat associations of small mammals in two forest types in southern Oregon

Creator:

Johnston, Aaron N.

Abstract:

I studied small-mammal communities and their response to grazing in mixed-conifer forests and oak woodlands in the Cascade-Siskiyou National Monument in southern Oregon. My objectives were to (1) compare small-mammal communities among forest types and grazing intensities, (2) identify riparian affiliated species, and (3) describe microhabitat associations. Over two years,...
