The authors examined the effects of pre- and post-fire management strategies on the establishment of non-native plant species after high severity wildfire. They further considered other biotic and abiotic factors that may also influence non-native species establishment post-fire.
The authors analyzed the developmental spatial and structural patterns of mixed-conifer forest stands along an elevation gradient in response to altered disturbance regimes, specifically fire suppression.
The authors studied the effects of past disturbances, specifically beetle outbreak and extreme drought, on the spatial variability of fire severity.
The authors examined the effects of prescribed fires on subsequent fire behavior and fire severity one to nine years prior to the Rodeo-Chediski fire.
The authors compared current forest vegetation structure and composition across an elevational gradient to a dendrochronological reconstruction of vegetation from 1876 to understand the effects of forest management, specifically fire exclusion.
The authors reconstructed the contemporary and historical fire regime of a ponderosa pine forest and a mixed-conifer forest to determine how fire exclusion may have affected the forests’ structure and composition on the San Francisco Peaks in Northern Arizona.
The authors looked at the regeneration of ponderosa pine forests after ten high-severity crown fires that occurred from 1948 to 1977.
The authors used tree-ring chronologies to compare timing of historic ponderosa pine recruitment to tree-ring based climate reconstruction variables, including annual precipitation, PDSI, Southern Oscillation Index, and Niño3 sea surface temperature (SST) index, and also fire disturbance to understand how both climate and fire have influenced current forest stand structure.
The authors reconstructed fuel and fire behavior variables across an elevation gradient in Grand Canyon forests to estimate the change in canopy fuels since 1880 and to project future canopy fuels and associated potential fire behavior into the near future (2040).
The authors looked at species specific patch development, establishment, and the effects of climate and/or disturbance regimes, including fire suppression, within ecotones of mixed-conifer and ponderosa pine ecosystems.
