Frogs and Toads of North Dakota
North Dakota doesn’t have a great variety of frogs and toads but they are some great species.
There are only two true frog species in the state, which makes it easy to identify them.
The Northern Leopard Frog has spots all over it’s body which is how it gets it’s name. They are often found in or on the shore of bodies of water.
The Wood Frog is more of a land frog than the Northern Leopard Frog. It has a distinct mask around it’s eyes. They are a variety of different colors, from red, brown, and bronze.
The Gray Tree Frog and Cope’s Gray Tree Frog are nearly identical besides their calls and chromosome numbers. The frogs are found in the eastern part of the state.

The Boreal Chorus frog is a small frog found throughout the state. They have lines that run down their back.
The American Toad is found along the eastern edge of the state. The cranial crest and the parotoid gland of the toad do not touch or they connect with a spur.
The Canadian Toad is found in the eastern half of the state. Its cranial crest form a boss (bump) in between its eyes.
The Woodhouse’s Toad cranial crest forms opposing L shapes. It is found throughout the state.
Great Plains Toad’s cranial crest forms a V shape. It is found throughout the state.
The Plains Spadefoot toad is the only spadefoot toad in the state. Look at the rear foot of the toad and you will find a keratinized spade on it which no other toad or frog in the state has.
