Invasive Species — Red-legged Frog (Rana aurora)
Management strategies have not been developed for red-legged frogs in Alaska, although it is illegal to introduce any aquatic organism into Alaskan waters. Ironically, this species is declining throughout its native range, and a subspecies, the California red-legged frog (Rana aurora draytonii) is Federally-threatened. Research in Alaska will focus on assessing the effects of red-legged frogs on native Alaskan amphibians. Given the remoteness of its introduced range in Alaska, eradication of this species would be logistically improbable. Instead, it is possible that if populations continue to decline in its native range, the Alaskan population could be used to seed new populations for restoration efforts in the lower 48. However, that remains to be determined.
