Introduction
This page offers downloadable data layers, associated metadata, and map viewer for the core NaFIS variables (i.e., forest/non-forest, forest type, forest type group, volume, basal area, biomass, and quadratic mean diameter), regional add-on variables (e.g., dead wood in west, stem density, and proportion forest in east), and data layers that can be linked to the public CN key in Version 3.0 of the FIA database.
