LANDFIRE’s Biophysical Settings (BpSs)
BpS models represent the vegetation system that may have been dominant on the landscape prior to Euro-American settlement. These models are based on a combination of the current environment and an approximation of the historical disturbance regime. Read more.
Check out this 3-minute tutorial for a quick refresher on the basics of Biophysical Settings Models.
Use this page as a starting point to explore the most prevalent BpSs for your analysis area. In addition to the charts and maps, the historical disturbance data can be directly accessed using this site.
