LANDFIRE 2023 Forest Canopy Bulk Density (CBD) AK

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: July 15, 2025 | Last Modified: 20241218
LANDFIRE's 2023 Update (LF 2023) Forest Canopy Bulk Density (CBD) describes the mass of available canopy fuel per unit canopy volume that would burn in a crown fire. A spatially explicit map of CBD supplies information used in fire behavior models to determine the spread characteristics of active crown fires across the landscape. CBD for disturbed and non-disturbed areas is determined via a general linear model (GLM) relating LF's Forest Canopy Height (CH) and Cover (CC) to CBD (Reeves et al 2009). To designate disturbed areas where CBD is modified, the aggregated Annual Disturbance products from 2014 to 2023 in the LF Fuel Disturbance (FDist) product are used. All existing disturbances between 2014-2023 are represented in LF 2023, and the products are intended to be used in 2024 (the year of release). When using any product from the LF 2023 fuel product suite, users should consider adjusting fuel layers for disturbances that occurred after the end of the 2023 fiscal year (after October 1st, 2023). Disturbances that occurred after the end of the 2023 fiscal year are not accounted for within LF 2023 fuel products. Learn more about LF 2023 at https://landfire.gov/data/lf2023.
