Fire Severity Mediates Marten And Fisher Occurrence: Impacts Of The Dixie Fire On A Carnivore Community, Christopher James Collier
Fire Severity Mediates Marten And Fisher Occurrence: Impacts Of The Dixie Fire On A Carnivore Community, Christopher James Collier
Cal Poly Humboldt theses and projects
The consumption of an astounding one million acres resulted from California’s largest single fire to date, the 2021 Dixie Fire. The social and economic losses associated with the fire were immediately apparent, but the effects on wildlife remained unknown. While previous research has suggested mixed or low severity fire may be beneficial to certain wildlife species, the responses to megafires are poorly understood for many carnivores. To better understand these responses to severe fire, I used a random sampling design stratified by burn severity to survey in and around the Dixie Fire footprint using baited camera stations. This allowed me …
Post-Fire Vegetation And Pyrodiversity Influence Breeding Abundances Of Lewis's Woodpeckers In The Eastern Cascades, Oregon, Brittany Welch
Post-Fire Vegetation And Pyrodiversity Influence Breeding Abundances Of Lewis's Woodpeckers In The Eastern Cascades, Oregon, Brittany Welch
Cal Poly Humboldt theses and projects
Lewis’s woodpeckers (Melanerpes lewis) are described as "burn specialists" due to their preference for breeding in recently burned pine forests in the western US. However, despite increasing fire activity, this species experienced a 48% range-wide decline between 1968 and 2019, which raises questions about their adaptability to altered fire regimes in the region. We partnered with the Oregon Department of Fish & Wildlife to investigate how Lewis’s woodpeckers in the eastern Cascades, Oregon were influenced by post-fire habitat characteristics such as snag size, snag density, and burn severity across five wildfires that varied in fire age, size, and …
