Developing a Topographic Model to Predict the Northern Hardwood Forest Type within Carolina Northern Flying Squirrel (Glaucomys sabrinus coloratus) Recovery Areas of the Southern Appalachians

Confusion matrix for our best approximating model (Elevation + TEI) showing predicted versus observed forest types for sample points in areas above 1219.2.2 m in elevation of western North Carolina, eastern Tennessee, and southwest Virginia which composed our study area (). Sampling took place between June 2012 and January 2013. Overall accuracy for the prediction of all three forest types was 67% and for the northern hardwood forest type 80%.
