Environmental drivers of large, infrequent wildfires : the emerging conceptual model
  • be typified based on climatic conditions that determine both fuel moisture and fuel amount. The concept distinguishes 3 ecosystem types : 1) biomass-rich, rarely dry ecosystems where fuel moisture rather than fuel amount limits LIFs; 2) biomass-poor, at least
  • seasonally dry ecosystems where fuel amount rather than fuel moisture limits LIFs; and 3) biomass-poor, rarely dry ecosystems where both fuel amount and fuel moisture limit the occurrence of LIFs.

  • To determine expected wildfire behavior at these semiarid mountain sites, the AA. analyzed fuel conditions at Mount Irish and the Clover Mountains, in southeastern Nevada. Current fuels were quantified by herbaceous and shrub vegetation cover, down
  • dead woody debris, litter and duff bulk density, canopy bulk density (CBD), and biomass. To reconstruct canopy fuels at each site, all woody stems on twelve 0.1 ha plots were mapped, measured, and cored. Increment cores were processed using
  • dendrochronological methods; establishment dates and reconstructed tree diameter at breast height (DBH) were then used as input for simulation models. Canopy fuels and potential fire behavior over time were modeled using the Forest Vegetation Simulator (FVS) and its
  • Fire and Fuels Extension. The results indicate that patterns and processes of fuel accumulation and potential fire behavior are not spatially or temporally homogenous in these mixed-conifer woodlands.
