Alaska Amphibian Database
Amphibians are ectotherms (cold-blooded) and require relatively mild temperatures to survive. To cope with Alaska’s low temperatures, they hibernate over winter. Alaska is home to one newt, two species of salamander, three species of frog, one tree frog, and one toad. These species are primarily restricted to the Southeast, with only the cold-adapted wood frog extending into interior Alaska. We have compiled occurrence records for these taxa in Alaska based on data submissions from research scientists and citizen scientists. From the occurrence records we have extrapolated ranges for each species. For additional information and global occurrence records of amphibians, visit vertnet.org.
Note: Sensitive records (e.g. breeding populations) have been omitted from maps. For an additional 17 records of western toads, wood frogs, and rough skinned newts, please contact jpreimer (at) uaa.alaska.edu.
