LANDFIRE 2020 Fuel Vegetation Height (FVH) AK
LANDFIRE (LF) 2020 Fuel Vegetation Height (FVH) represents a modified pre-disturbance version of the Existing Vegetation Height (EVH) product from previous LF versions. LF 2020 update EVH is mapped as continuous estimates of canopy height for tree, shrub, and herbaceous lifeforms with a potential range from 0m to 50m or more. To translate continuous EVH values into fuel model assignments, EVH values are binned to new groups to improve canopy fuel predictions. FVH leverages fuel transition assignments related to disturbed areas by re-establishing pre-disturbance vegetation. Fuel products were created with LF 2020 vegetation in non-disturbed areas, but pre-disturbance vegetation was used in disturbed areas using fuel rule sets.
FVH was developed using the latest Annual Disturbance products from the effective disturbance years of 2012 to 2020 to provide informed changes by disturbance type, severity, and time since disturbance (TSD). The capable fuels process calculates fuel assignments for disturbed areas using an “effective year”. This process considers all the existing disturbances included in LF 2020 and assigns fuels to the pre-disturbance vegetation based on the adjusted TSD, making the products "2022 capable fuels" intended for use in 2022 and accounting for two years of disturbance recovery.
