American chestnut (Castanea dentata)
Model Reliability: Current Distribution Only
Current Distribution Only
The model reliability (ModRel) for American chestnut was too low (< 0.14), therefore only the current Forest Inventory & Analysis distribution is shown.

Interpretation Guide
American chestnut is very rare (0.5% of area) as resprouts from its former glory days and now its core area is along the Appalachian spine. Its low abundance dictates a model we cannot rely on so that we cannot map potential future habitat. However, efforts to breed the species to be resistant to the chestnut blight, and potentially other onslaughts in the future, provide hope that the species will remain a force in the future.
Family: Fagaceae
Guild: persistent, large seeded, advance growth dependent
