LANDFIRE 2020 Forest Canopy Cover (CC) HI
LANDFIRE's (LF) 2020 Forest Canopy Cover (CC) describes the percent cover of the tree canopy in a stand, CC is a vertical projection of the tree canopy cover onto an imaginary horizontal plane. Utilizing LF Reference Database (LFRDB) plots, a training data set to model disturbed CC was created. Field referenced CC values are calculated for each plot using the canopy fuel estimation software in Forest Vegetation Simulator (FVS). Statistical analysis of plot variables indicates that LF 2020 Fuel Vegetation Type (FVT), Fuel Vegetation Height (FVH), and Fuel Vegetation Cove (FVC) demonstrate some influence on CC. To model this relationship pre-disturbance CC and Canopy Height (CH) are used as predictors of disturbed CC; developing a linear regression equation per FVT and disturbance type/severity. In LF 2020, fuel products were created with LF 2020 vegetation in non-disturbed areas, but pre-disturbance vegetation was used in disturbed areas to derive disturbed CC from linear regression equations. CC is used in the calculation of Canopy Bulk Density (CBD) and Canopy Base Height (CBH). CC supplies information to fire behavior models to determine the probability of crown fire initiation, provide input in the spotting model, calculate wind reductions, and to calculate fuel moisture conditioning.
CC 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.
