Postfire woodpecker foraging in salvage-logged and unlogged forests of the Sierra Nevada
Year: 2008
In forests, high-severity burn patches—whereinmost or all of the trees are killed by fire—often occur within amosaic of low- and moderate-severity effects. Although therehave been several studies of postfire salvage-logging effects onbird species, there have been few studies of effects on bird speciesassociated with high-severity patches in forests that haveotherwise burned at lower severities. From 2004 to 2006, we investigatedthe foraging presence or absence of three woodpeckerspecies, the Black-backed (Picoides arcticus), Hairy (P. villosus),and White-headed (P. albolarvatus) Woodpeckers,…

Burned landscapes of southwestern Oregon: what's in it for Northern Spotted Owls?
Year: 2008
Northern spotted owls are known to spend time in areas burned by wildfire, but there has been little scientific investigation of how and why they use these landscapes. A trio of wildfires in southwestern Oregon during the summers of 2001 and 2002 burned through dozens of documented spotted owl territories, providing a rare opportunity to study many important aspects of how these raptors respond to wildfire in dry forest ecosystems. For this project researchers used radio telemetry and demographic surveys to investigate habitat selection, home range size, occupancy, productivity and survival…
