North American Porcupine (Erethizon dorsatum): Known from the mainland and some of the near islands. Contrary to the ADF&G page for this species (which states they occur everywhere except the [Southern Outer Islands]), Porcupines are not known from Baranof Island nor probably Chichagof Island. There are also no collections from Admiralty Island, nor many of the other inner islands.
