Associations of forest-floor vertebrates with coarse woody debris in managed forests of western Oregon

Article Abstract:

An understanding of habitat associations of forest-floor vertebrates can boost forest management guidelines and regulations. This research, undertaken in the western Oregon Cascades on managed forest land, aimed to assess forest-floor vertebrate associations at the stand level and near the site of species capture. The findings of this research include a positive link between rough-skinned newts and bare ground cover in spring pitfall trapping and a positive association in spring between Trowbridge's shrews and fern cover at the stand level. It is suggested that the retention of coarse woody debris (CWD) in managed stands should more closely model CWD found in natural stands.

Response of amphibians to clearcutting, burning, and glyphosate application in the Oregon Coast Range

Article Abstract:

Researchers examined the numbers of amphibians on red alder sites in the Oregon Coast Range, then re-examined population numbers after the sites had been either clearcut and burned, or clearcut, burned and sprayed with glyphosate herbicide. The numbers were measured using pitfall traps. Capture rates of Dunn's salamanders, red-legged frogs and rough-skin newts did not alter significantly after logging. Capture rates of Pacific giant salamanders and ensatinas decreased, and capture rates of western redback salamanders increased. Herbicide spraying had no significant effect on capture rates.

Response of small mammals to clearcutting, burning, and glyphosate application in the Oregon Coast Range

Article Abstract:

The effects of forest management treatments on the abundance of small mammal species were investigated. No differences in the capture rates were found between buffer and upslope areas prior to logging for the six species analyzed. Increases and decreases in capture rates were similar between logged and burned and logged, burned and sprayed areas. Changes in small mammal abundance after spraying had been linked with indirect effects of changes in vegetation.
