Funded Research Projects: FOREST ECOLOGY

Calibration and validation of satellite burn-severity indices with field data in forests of the Interior Pacific Northwest

Research Sponsored By: US Forest Service
Principal Investigator: Brian Harvey
Project Description
The U.S. Forest Service Geospatial Technology and Applications Center (GTAC) routinely prepares remote-sensing-based burn severity assessments of large wildfires on Forest Service (FS) lands as products of its Rapid Assessment of Vegetation Condition After Wildfire (RAVG) program. Existing burn severity models (using regression equations to relate field data to satellite data) were developed from field data and satellite imagery from burned areas in the Sierra Nevada and northern Californina (USFS Region 5), and are likely inadequate to capture burn severity in forests of the interior Pacific Northwest (PNW). The goal of this project is to develop and document similar models tailored to the PNW. In collaboration with GTAC, we will perform sample design, data collection, analysis and related work necessary to develop and document models of RAVG burn severity measures representative of dominant forest types found in the interior PNW (eastern Oregon and Washington, western Montana and northern Idaho).
