Fire management data

Wildfire Risk (November 2009)

The Wildfire Risk data model identifies areas with a relatively high risk of destructive wildfire. The intent of this layer is to highlight areas where management is most likely to reduce the risk of wildfire damage, which is defined as reducing the impact of wildfire on natural resources, and human infrastructure and development. The model combines three modeled fire behavior parameters (rate of spread, flame length, crown fire potential) and one modeled ecological health measure (fire regime condition class) with wildland urban interface areas and ignition probability.

Historical Range of Variation for Potential Natural Vegetation Types of the Southwest (June 2007)

Descriptions of the Historical Range of Variation or Variability (HRV) characterize the change over time and space in the condition of the Southwest’s major vegetation types and the ecological processes that shape those types. HRVs enable land managers and the public to understand the drivers of change in our region’s major vegetation types.

Historical Fire Return Intervals for Arizona and New Mexico (May 2006)

Synthesizes the scientific literature on historical fire return intervals associated with the major vegetation systems across Arizona and New Mexico. Included is a crosswalk table for use with the Southwest Regional Gap Analysis Project's land cover dataset and three ArcGIS layer (.lyr) files that enable the user to mimic the report graphics.
