Publications in Fire Ecology

Special Issue: Fire and Wildlife Interactions
Pages: 1-2
DOI: 10.4996/fireecology.0402001

Fire regimes and vegetation structure and composition form a direct feedback loop, where fire regimes shape patterns in the vegetation and vegetation affects fire regime attributes. For decades, researchers focused their attention on the essential relationships between fire and vegetation; however, there is a vast gap in our knowledge about the more mobile inhabitants of these habitats.  [Read More]

Modeling the Effects of Fire Severity and Spatial Complexity on Small Mammals in Yosemite National Park, California
Pages: 83-104
DOI: 10.4996/fireecology.0402083

We evaluated the impact of fire severity and related spatial and vegetative parameters on small mammal populations in 2 yr- to 15 yr-old burns in Yosemite National Park, California, USA. We also developed habitat models that would predict small mammal responses to fires of differing severity. We hypothesized that fire severity would influence the abundances of small mammals through changes in vegetation composition, structure, and spatial habitat complexity.  [Read More]

Truffle Abundance in Recently Prescribed Burned and Unburned Forests in Yosemite National Park: Implications for Mycophagous Mammals
Pages: 105-114
DOI: 10.4996/fireecology.0402105

Truffles are an important food resource for wildlife in North American forests, but decades of fire exclusion have altered the availability of this resource. In Yosemite National Park, resource management policies seek to restore essential forest processes such as fire while minimizing adverse ecological impacts that may result from burning decades of accumulated fuels.  [Read More]

Principles of Effective USA Federal Fire Management Plans
Pages: 59-83
DOI: 10.4996/fireecology.1102059

Federal fire management plans are essential implementation guides for the management of wildland fire on federal lands.  Recent changes in federal fire policy implementation guidance and fire science information suggest the need for substantial changes in federal fire management plans of the United States.  Federal land management agencies are also undergoing land management planning efforts that will initiate revision of fire management plans across the country.  [Read More]
