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

Table 3

The best approximating logistic model (Elevation + TEI) explaining presence or absence of northern hardwoods 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. Forest types are notated as follows: northern hardwood (NH), northern red oak (NRO), and red spruce-Fraser fir (RSFF).
