Bird communities in managed conifer stands in the Oregon Cascades : habitat associations and nest predation

Creator:

Vega, Robyn M. S.

Abstract:

Green-tree retention is being implemented on state and federal lands in Oregon. Silvicultural prescriptions with tree and snag retention are thought to mimic natural disturbance patterns in the Pacific Northwest more closely than traditional silvicultural practices, which reduce structural complexity. The effects of green-tree retention on native bird species in...

Population biology of rare mariposa lilies (Calochortus: Liliaceae) endemic to serpentine soils in southwestern Oregon

Creator:

Fredricks, Nancy Ann

Abstract:

Population dynamics, plant communities, and abiotic environments of three narrowly endemic, allopatric mariposa lilies (Calochortus Pursh) are described and compared. All were restricted to ultramafic soils in southwestern Oregon with high concentrations of nickel, zinc, and chromium, and low calcium to magnesium ratios. Soils inhabited by the three species differed...

Watershed-level patterns among stream amphibians in the Blue River watershed, West-Central Cascades of Oregon

Creator:

Hunter, Matthew G.

Abstract:

Most recent research on stream amphibians in the Pacific Northwest has focused on associations with reach-level or stand-level environmental features. Little is known about landscape-level distributions of these species or landscape-level aspects of their life-histories. I used a watershed-wide sample and logistic regression to develop models and maps of probability...
