The authors studied four wildland fire-use fires across an altitudinal gradient to examine the restorative effects of wildfire on areas that experienced unusually long fire-free periods. The authors stratified study sites by elevation with the lowest elevation site dominated by ponderosa pine and gambel oak, the mid-elevation site dominated by ponderosa pine, white fir, aspen, and Douglas fir, and the high-elevation sites dominated by subalpine fir and Engelmann spruce.
The authors examined the effects of pre-fire thinning and fuel reduction treatments on post-fire tree survival and forest structure and composition in high severity burned areas versus untreated control plots.
The authors quantitatively assessed the spatial and temporal patterns of tree invasion into montane and subalpine grasslands in northern New Mexico. They further assessed the effects of topography, climate, and land use practices on these changes in grassland structure over time.
This article assessed the ability of Chihuahua pine (Pinus leiophylla) to survive fire or resprout after fire based on tree age and fire intensity.
In this article, the authors formulate a model based on mixed- and/or variable-fire severity and test its applicability to ponderosa pine and mixed conifer ecosystems in the US Rocky Mountains.
The authors tested a series of minimal-impact treatments including: (1) thinning of small trees (diameter ? 12.7 cm) and prescribed fire; (2) thinning of small trees located close to large old trees and prescribed fire; (3) prescribed fire only; and (4) control, to determine their effectiveness at reducing hazardous fuels and restoring historic forest conditions.
The authors characterized the historic community stand dynamics of Quercus gambelii to understand the structure and patterns of regeneration and recruitment over time.
The authors examined post-wildfire snag and down course woody debris characteristics including quantity, quality, and changes over time after severe wildfire.
The authors examined long-term, historic fire and post-fire recruitment chronologies of ponderosa pine in the Black Hills to evaluate the relationship between climate, fire years, and tree recruitment patterns and their effects on forest structure over time.
This article described the spatial and temporal patterns and potential trends of wildfire in the Mojave Desert from 1980 to 2004.
