A summary of the latest USDA Forest Inventory and Analysis data for the state of Vermont. The network of randomly distributed inventory plots are designed to capture broad temporal changes in the condition of the nation’s forest resource. Spatial coverages of species distribution, extent of forest cover and biomass compliment the yearly data summaries to capture an unbiased estimated of the state of Vermont's forests.

Reserved status, owner group, forest type, stand-size class, regeneration status, and stand density are used to define forest conditions. In older plot designs, plot center or subplots locations were rearranged such that the entire plot sampled a single condition, while in the current design, different conditions are “mapped” on the same plot.
