Alaska Amphibian Database
Amphibians are ectotherms (cold-blooded) and require relatively mild temperatures to survive. In Alaska amphibians are primarily restricted to the southeast, with only the cold-adapted wood frog extending into interior Alaska. Amphibians in the state hibernate in the winter to cope with low temperatures. Alaska is home to one newt, two species of salamander, three species of frog, one tree frog, and one toad.
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.
