This study was meant to determine the habitat preference of porcupines (Erethizon dorsatum) at the second (home range), third (forest stand), and fourth (tree species) order of selection. I measured tree species composition, stand density, tree height, canopy width, and soil depth for a 100 hectare area of the Kip Tract in Canton NY. I calculated relative frequency, relative abundance, and relative dominance of each tree species. I tracked porcupines for six months using radio telemetry.
