Wildland fire use (WFU) is a tool that has been utilized by managers in the Forest Service since the 1970s to reintroduce fire as a natural ecosystem process. Today it is also applied to meet additional resource objectives including restoration and maintenance of ecosystems and fire hazard reduction through lessening the extent and severity of future fires. Few studies have characterized the spatial pattern of fire severity in either wildland or WFU fires. The objectives of this report are to: 1) use remotely sensed data and geospatial analysis to understand the influence of weather, topography, and fuels on fire severity, and 2) characterize fire severity patch dynamics for the Albanita-Hooker, Crag, and Clover WFU Fires in the southern Sierra Nevada. A regression tree analysis was completed with elevation, slope, aspect, time since last fire, burn frequency, wind speed, temperature, relative humidity, energy release component, and vegetation type as explanatory values to describe change in canopy cover derived from remotely sensed data
