Board foot volume, calculated using FVS, of live trees with DBH >= 6". Masked using the Forest Mask layer to remove non-forested areas. See the FVS Variant Overview documentation for more details about the FVS volume calculations.

Units: Scribner board feet per acre for the PN, WC, and EC variants; Scribner Decimal C board feet per acre for the IE variant.

Global model accuracy Pseudo-R^2=0.7016, RMSE=18295

This model is a composite of 8 sub-models, one per FVS Variant and cover class. The Model Classes layer shows where each sub-model was used.
