Diversity and abundance of birds across a hardwood gradient in early seral Douglas-fir plantations

Ellis, Tana M.

Abstract:

Recent evidence suggests that population declines of some avian species may be driven primarily by reduced quantity and diversity of early-successional habitat on the breeding grounds. Increasing intensity of forest management on private lands and decreased harvest rates on federal lands has resulted in a loss of the diverse early-successional...

The use of burned forest by breeding birds following the Biscuit Fire in southwest Oregon

Creator:

Donaghy Cannon, Michelle M.

Abstract:

Fire severity is hypothesized as an important driver of bird responses to wildfire. For those species that typically respond negatively to increasing severity, Accessibility of high-severity burned forest may be dependent on the proximity of unburned or low-severity burned forest to meet all of the needs of breeding bird species...
