From Natural History of Southeast Alaska
The primary reference for the occurrence and distribution of Mammals in Southeast Alaska is Mammals and Amphibians of Southeast Alaska (MacDonald and Cook 2007).
Humans (Primates)
Hominidae (Humans: 1 species)
Scientific Name | Common Name | Summary | Homo sapiens | Human | Present in the area for over nine thousand years, based on archaeological evidence found at different locations. |
Rodents (Rodentia)
Sciuridae (Squirrels and Marmots: 4 species)
Castoridae (Beavers: 1 species)
Scientific Name | Common Name | Summary | Castor canadensis | Beaver | Present throughout most of the region where there is suitable habitat. Apparently poorly documented with specimens, however. |
Dipodidae (Jumping Mice: 2 species)
Cricetidae (Voles and Lemmings: 11 species)
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). |
Muridae (Old World Rats and Mice: 2 species)
Scientific Name | Common Name | Summary | Mus musculus | House Mouse | There are apparently few collections of this introduced species from the region, with most of them from the 1940s or earlier(?). One 2006 collection in Arctos from the Mendenhall Wetlands is recorded as this species. Current status is not well known. |
Rattus norvegicus | Brown Rat | Introduced species so far only known from near populated areas (where it is associated with human activity?). |
Scientific Name | Common Name | Summary | Erethizon dorsatum | North American Porcupine | 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. |
Hares and Pikas (Lagomorpha)
Leporidae (Hares: 1 species)
Scientific Name | Common Name | Summary | Ochotona collaris | Collared Pika | Currently known only from White Pass on the border out of Skagway, it is possible they may occur in other mountainous areas along the border. |
Shrews (Soricomorpha)
Soricidae (Shrews: 4 species)
Bats (Chiroptera)
Scientific Name | Common Name | Summary | Lasionycteris noctivagans | Silver-haired Bat | Southeast Alaska seems to be at the northern edge of this species' range and distribution in the region is poorly known. Only a few specimens have been collected from the region, including Ketchikan, Wrangell, and Petersburg. More recently, acoustic monitoring has shown they are present at Gustavus. |
Lasiurus cinereus | Hoary Bat | This species is so far known only from calls detected by passive acoustic monitoring. This monitoring has been going on since 2012(?) throughout the region as part of a project run by the ADF&G (per talk given by Karen Blejwas in Sitka, 10 March 2014). |
Myosotis yumanensis | Yuma Myotis | Known from extreme southeastern part of region (from a paper published in 2014 in "Northwestern Naturalist" by Olson, MacDonald, and Blejwas). |
Myotis californicus | California Myotis | Known primarily from the southern outer islands, and the El Capitan Cave area of Prince of Wales Island in particular. They may be more widespread in the region (and there is at least one report from northern Southeast) - recent and on-going work by the Alaska Department of Fish and Game (non-game division) may reveal more about the distribution of this species in the region. |
Myotis keenii | Keen's Myotis | |
Myotis lucifugus | Little Brown Bat | Common, occasionally found in attics. |
Myotis volans | Long-legged Myotis | |
Carnivores (Carnivora)
Ursidae (Bears: 2 species)
Scientific Name | Common Name | Summary | Ursus americanus | Amerian Black Bear | |
Ursus arctos | Brown Bear | Common from sea level to alpine, except on southern islands where it does not typically occur. |
Canidae (Dog: 3 species)
Scientific Name | Common Name | Summary | Canis latrans | Coyote | Present on the mainland. |
Canis lupus | Wolf | |
Vulpes vulpes | Red Fox | Introduced to islands in southeast for fur, no populations are known to have persisted. There are second-hand reports of single animals from North Baranof and West Chichagof. |
Otariidae (Eared Seals: 3 species)
Phocidae (Seals: 3 species)
Scientific Name | Common Name | Summary | Mirounga angustirostris | Northern Elephant Seal | |
Phoca vitulina | Harbor Seal | |
Pusa hispida | Ringed Seal | A sick yearling seal thought to be this species was found near Yakutat in 2012. This is well outside expected range, and a DNA sample was reportedly sent for id confirmation:

Bovidae (Sheep and Goats: 2 species)
Cervidae (Deer and Relatives: 4 species)
