Graduation date: 2008Previous research examining the influences of post-fire salvage logging on abundances of birds has focused primarily on the response of cavity-nesting species. There is limited research in regard to the impact of salvage logging on a broader range of bird species. In addition, little is known about how different intensities of salvage logging influence bird abundances. I compared densities and relative abundances of bird species among two different intensities of salvage logging and an unsalvaged treatment in a post-fire forest of mixed conifers at Davis Lake, Oregon. I also examined the potential of vegetation variables that describe habitat structure to predict densities of birds, and the use of snags for foraging by two species of woodpeckers. Salvage logging influenced the density or relative abundance of seven species of birds, though the pattern of the influence varied. Five species (black-backed woodpecker, hairy woodpecker, western wood-pewee, brown creeper, and yellowrumped warbler) had greater densities or relative abundances in the unsalvaged treatment than in either treatment of salvage logging. Two species (dark-eyed junco and fox sparrow) had greater densities in salvaged treatments than in the unsalvaged treatment. Salvage logging did not significantly influence density or relative abundance of eight species (red-breasted nuthatch, white-breasted nuthatch, dusky flycatcher, house wren, American robin, western tanager and chipping sparrow) and one genus of swallows (Tachycineta). Densities of yellow-rumped warblers increased with increasing density of snags. Densities of fox sparrows and dark-eyed juncos increased with increasing volume of shrubs. Vegetation variables did not strongly predict densities or relative abundances for twelve species and one genus of birds. Diameter of snags selected for foraging by black-backed and hairy woodpeckers did not differ between species of woodpecker or among treatments of salvage logging. Both species of woodpeckers selected snags for foraging with larger diameters than the mean diameter of snags in both unsalvaged and salvage treatments. Salvage logging influenced densities or relative abundances of some noncavity nesting birds and cavity-nesting birds. Maintaining unsalvaged areas in burned forests will provide habitat for species of birds negatively influenced by salvage logging. Retaining large snags after salvage logging will provide foraging habitat for woodpeckers.
