This map depicts the forested regions in the western United States. Data was obtained from the the Sagestitch map and other state-level GAP land cover maps and merged into 90m raster dataset.
Human-induced fires have increased the frequency at which fires occur on the landscape. Fires increase the probability of invasion by exotic plant species as well as destroy existing habitats. This model was developed to depict the density of human caused fire ignition points throughout the western United States. Data from the National Fire Ignition Database from 1986 to 2001 was used to calculate the density of human-induced fire ignitions (ignitions / km).
Elevation in the western United States obtained from the National Elevation Dataset. Data was converted from float point to integer format and re-sampled from 30m resolution to 180m resolution.
