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,…

Lessons of the Hayman fire: weeds, woodpeckers and fire severity
Year: 2008
This project took advantage of pre-fi re data gathered within the perimeter of Colorado’s 2002 Hayman Fire. Researchers studied the unique fi re regime of Front Range ponderosa pine forests, and fi re effects on understory-plant communities and American Three-toed Woodpeckers. Results confirmed that historically, the diverse structure of these forests was maintained by a mixed-severity fi re regime that included large areas of severe fi re. In addition, researchers found that much of the burn meets habitat requirements for American Three-toed Woodpeckers, and that understory plant species…
