North Dakota has a sparse fauna of amphibians and reptiles. While individual populations may get quite high, species diversity is low. The semi-arid climate provides only marginal conditions for breeding and hibernation of amphibians, while low winter temperatures and the short growing season appear to be primary limiting factors for reptiles. Several of the species listed below are very rare or infrequently found and are in quite localized populations.

 
AMPHIBIANS Tiger Salamander Ambystoma tigrinum
Plains Spadefoot Toad Scaphiopus bombifrons
Great Plains Toad Bufo cognatus
Rocky Mountain (Woodhouse's) Toad Bufo woodhousei
Boreal Chorus Frog Pseudacris nigrita
Leopard Frog Rana pipiens
