The purpose of the State of Montana Wildfire Risk Assessment (MWRA) is to provide foundational information about wildfire hazard and risk to highly valued resources and assets across the assessment area. Such information supports regional fuel management planning decisions, as well as revisions to land and resource management plans. A wildfire risk assessment is a quantitative analysis of assets and resources and how they would be potentially impacted by wildfire. The MWRA analysis considers several different components, each resolved spatially across the region, including:
• likelihood of a fire burning, • the intensity of a fire if one should occur,
• the exposure of assets and resources based on their locations, and • the susceptibility of those assets and resources to wildfire.
This canopy bulk density dataset is an input for generating the MWRA fuelscape. Units are in kilograms/cubic meters * 100. Data finalized 12/20/2019.
<div style='text-align:Left;'><div><div><p><span><span>The MWRAfuelscape consists of geospatial data layers representing surface fuel model, canopy base height, canopy bulk density, and topography characteristics (slope, aspect, elevation). The fuelscape was developed from LANDFIRE Remap 2016 30-m raster data and edited based on feedback from interagency fuels and fire staffacross Montana. Additionally, the fuelscape was updated using RAVG, MTBS, and fire perimeter datasets where available to account for wildfire disturbances that occurred between 2017 and 2019. The fuelscape was also updated with FACTS/NFPORS treatment data and DNRC treatment data, provided by MT DNRC staff.</span></span></p><p><span>Note: LANDFIRE disturbance records reported a large fire perimeter (approximately 30,000 acres) in the Breckenridge, CO area from 2015. During the fuelscape calibration workshop, this was identified as an error in the FACTS database carried forward in LANDFIRE Remap. This record was removed from the fuel disturbance grid to prevent misrepresentation of fuel reduction within the original treatment polygon.</span></p></div></div></div>
This dataset was developed for the Montana Department of Natural Resources and Conservation’s Forestry Division by Pyrologix LLC (www.pyrologix.com).
<div style='text-align:Left;'><div><div><p><span>The user must be aware of data conditions and must ultimately bear responsibility for the appropriate use of the information with respect to possible errors, possible omissions, map scale, data collection methodology, data currency, and other conditions specific to certain data.</span></p></div></div></div>
