Amphibians and Reptiles

Northern Leopard Frog at Tsu Lake (GNWT/J. Eberbach)
Last updated: October 2011

Amphibians are considered excellent indicator species of environmental health. Three frog species are known in the NWT: the boreal chorus frog (Pseudacris maculata), the northern leopard frog (Lithobates pipiens), and the wood frog (Lithobates sylvatica). Two toad species are known: the Canadian toad (Anaxyrus hemiophrys) and the western toad (Anaxyrus boreas). Only one reptile, the red-sided garter snake (Thomnophis sirtalis), lives in the NWT. A large red-sided garter snake hibernaculum (a place where the snakes hibernate) is found in Wood Buffalo National Park. The long-toed salamander (Ambystoma macrodactylum) and the terrestrial garter snake (Thamnophis elegans) are found along the NWT border and may have limited NWT distribution. See the Government of Northwest Territories, Department of Environment and Natural Resources (ENR) website for more information on amphibians and reptiles.

The map here shows locations where amphibians and reptiles have been sighted in the NWT. This information is based on observations sent to the Government of the Northwest Territories, ENR. ENR is increasing its efforts to better understand the distribution of amphibians and reptiles, and determine their most northern range and potential threats.
