This study used permanent sample plot data from the USDA Forest Service’s Forest Inventory and Analysis database to benchmark and calibrate three key submodels of the Forest Vegetation Simulator-Northeast variant (FVS-NE). Model predictions for total tree height (ht) and 5-year diameter (dbh5) and height increment (ht5) for the 20 most abundant species did not indicate any serious spatial trends. FVS-NE predictions for total ht performed moderately well, as mean bias averaged 0.9 5.2 ft (mean…

Comparing strategies for modeling individual-tree height and height-to-crown base increment in mixed-species Acadian forests of northeastern North America
Various methods for predicting annual tree height increment (∆ht) and height-to-crown base increment (∆hcb) were developed and evaluated using remeasured data from permanent sample plots compiled
Tree Height Increment Models for National Forest Inventory Data in the Pacific Northwest, USA
The United States national inventory program measures a subset of tree heights in each plot in the Pacific Northwest. Unmeasured tree heights are predicted by adding the difference between modeled
Evaluating Long-Term Seedling Growth Across Densities Using Nelder Plots and the Forest Vegetation Simulator (FVS) in the Black Hills, South Dakota, USA
Small-tree development affects future stand dynamics and dictates many ecological processes within a site. Accurately representing this critical component of stand development is important for
Development and evaluation of an individual tree growth and yield model for the mixed species forest of the Adirondacks Region of New York, USA
BackgroundGrowth and yield models are important tools for forest planning. Due to its geographic location, topology, and history of management, the forests of the Adirondacks Region of New York are
Trade-offs between three forest ecosystem services across the state of New Hampshire, USA: timber, carbon, and albedo.
It is suggested that utilizing temperate forests in New Hampshire for climate mitigation purposes through carbon storage and the cessation of harvest is appropriate at a site-dependent level that varies significantly across the state.

Evaluating Forest Vegetation Simulator predictions for southern Appalachian upland hardwoods with a modified mortality model
Twenty-five-year projection results show size-density trajectories consistent with the concept of maximum stand density index, and notable gains in accuracy were achieved by relaxing thresholds that activated a density-dependent mortality algorithm in FVS-Sn.
Testing the Lake States variant of FVS (Forest Vegetation Simulator) for the main forest types of northern Ontario
The Lake States variant of the FVS (Forest Vegetation Simulator) model (LS-FVS), also known as the LS-TWIGS variant of FVS, was validated for black spruce, white spruce and jack pine forests in northern Ontario.
Local calibration of the Forest Vegetation simulator (FVS) using custom inventory dataNo Title
Fort Bragg, North Carolina includes over 65,000 acres of longleaf pine forest, which is primary habitat for the endangered red-cockaded woodpecker (RCW). Effective management of the RCW depends on
Development of height to crown base models for thirteen tree species of the North American Acadian Region
The findings indicated that FVS-NE models were significantly biased for all species as the overall mean bias and root mean square error (RMSE) were 0.11 m and 1.80 m, respectively.
Development of regional height to diameter equations for 15 tree species in the North American Acadian Region
The study showed that the widely used FVS-NE model had significant prediction biases for all species in the region, and the best model form among those evaluated was the von Bertalanffy–Richards (vB-R), with added covariates that included crown competition factor, basal area in trees larger than subject tree and a climate-derived site index.
