Scientific Name	Common Name	Summary
Lemmus trimucronatus	Brown Lemming	Primary range of this species is more northern or interior than the region, but it is known from a pair of mountain sites near the border outside of Haines. Also one specimen in Arctos from Woronkofski Island has been identified as this species.
Microtus longicaudus	Long-tailed Vole	Present throughout the region except for Baranof Island and Kruzof Island. An endemic subspecies is known from Coronation, Forrester, and Warren Islands.
Microtus oeconomus	Root Vole	Found on the from the Northern Gulf Coast to the east side of upper Lynn Canal. Also on Chichagof Islands along with other associated smaller islands, and Baranof Island. Fossil remains have been found on Prince of Wales Island. The southern limit of this species is in Southeast Alaska.
Microtus pennsylvanicus	Meadow Vole	Known from at least three major mainland river valleys, the Chilkat, Taku and Stikine. Also found on Admiralty Island, and other islands near the mouth of the Stikine River.
Myodes gapperi	Southern Red-backed Vole	Found along the mainland as far north as the Stikine River. Also present on many of the southern inner islands.
Myodes rutilus	Northern Red-backed Vole	Present on the mainland at least as far south as LeConte Bay (according to MacDonald Cook 2007 - but arctos records show collections identified as this species from as far south as the southern mainland border). Reported from two islands, Douglas Island and Young Island (the latter in Yakutat Bay)
Neotoma cinerea	Bushy-tailed Woodrat	Apparently no recent collections - there no mapped collections from the region are in Arctos. MacDonald and Cook (2007) note that this species has previously been reported from along the Unuk, Stikine, and Taku Rivers, plus captures on nunataks in the Juneau Ice Field, all from the 1960s or earlier.
Ondatra zibethicus	Common Muskrat	Apparently widespread, but uncommon on the mainland and inner islands, with reports from Yakutat down to Revillagigedo Island including at Haines and one from Admiralty Island. Most reports seem to be from at or near the Stikine River (including delta and nearby larger islands).
Peromyscus keeni	Northwestern Deermouse	A species primarily of the Pacific Northwest Coast, it is widespread and common throughout Southeast Alaska except western Glacier Bay and the Northern Gulf Coast. This species is known from all the major islands and many of the secondary islands.
Phenacomys intermedius	Western Heather Vole	A single collection from the Chilkat Mountains near Excursion Inlet and collections from mountains near Hyder are the only ones known from the region so far, though it is probable this species occurs elsewhere in the mountains near the Canadian Border.
Synaptomys borealis	Northern Bog Lemming	Known on the mainland from Haines and Skagway south. Also scattered reports from some of the southern inner islands (including Kuiu Island).
