The Forest Vegetation Simulator (FVS) is a forest growth and yield model developed by the United States Forest Service and is used by natural resource managers and researchers. FVS is calibrated for specific geographic areas and uses a host of simulation models to forecast forest composition and structure.

Global simulations by the PIK group and collaborators, [2] using 6 different DGVMs (HYBRID, IBIS, LPJ, SDGVM, TRIFFID, and VECODE) used the same resolution as the general circulation model (GCM) that provided the climate data, 3.75 deg longitude x 2.5 deg latitude, a total of 1631 land grid cells.

When stocking, a tree's basal area is measured. The basal area is a cross-sectional area of the stump taken about 4.5 feet (1.4 m) above the ground. [7] The equation for calculating the basal area of trees in a stand is Basal Area = 0.005454 DBH 2, where DBH is the diameter of the tree at the aforementioned measuring height. [7]
The model considers transient changes in vegetation composition and structure in response to environmental change and is, therefore, classified as a Dynamic Global Vegetation Model [2] This new version of IBIS has improved representations of land surface physics, plant physiology, canopy phenology, plant functional type (PFT) differences, and carbon allocation.
The present extent of this vegetation group is estimated to be about 214,000 km 2 (83,000 sq mi) but the estimate prior to 1750 is 318,000 km 2 (123,000 sq mi). In 2001, the area covered by this vegetation group is estimated to be 65% of its pre-1750 coverage.
These forests are known for their rich diversity of plants and animals, which is due to several contributing factors, especially that the area was an unglaciated refugium for many species. It shares species with the high elevation Appalachian-Blue Ridge forests to the east, the hardwood forests to the west, and the mixed hardwood/ conifer ...
