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

Lessons of the Hayman fire: weeds, woodpeckers and fire severity
Year: 2008
This project took advantage of pre-fire data gathered within the perimeter of Colorado’s 2002 Hayman Fire. Researchers studied the unique fire regime of Front Range ponderosa pine forests, and fire 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 fire regime that included large areas of severe fire. In addition, researchers found that much of the burn meets habitat requirements for American Three-toed Woodpeckers, and that understory plant species that…

In a Ponderosa Pine Forest, Prescribed Fires Reduce the Likelihood of Scorched Earth
Year: 2008
The Malheur National Forest is located in the Blue Mountains on Oregon’s eastern side, the portion of the state that lies east of the Cascade Crest. In the mid 1990s, researchers and land managers conceived a suite of experiments to explore the effects of prescribed fire on forest health. The studies were designed to coincide with prescribed burns conducted by the USDA Forest Service. The experiments took place in the Emigrant Creek Ranger District, a remote area dominated by ponderosa pine. One of the research projects aimed to assess soil health after different intervals of fire frequency…
