Tree Frogs in South Dakota: Identification Guide and Best Places to Spot Them

Tree frogs in South Dakota are most often found in the eastern region, where wetlands, marshes, and slow-moving streams provide ideal habitat. Look for them in wooded areas near water, especially in the Missouri River floodplain and the Prairie Pothole region. They prefer spots with plenty of vegetation like cattails and shrubs where they can hide and hunt insects.

The best time to see tree frogs in South Dakota is from May through July, after warm rains. They are most active on humid evenings when temperatures stay above 60°F. Calling activity peaks after spring rains, so plan your outing on a warm, damp night. During dry spells, they become less active and harder to find.

South Dakota's most common tree frog is the gray tree frog (Hyla versicolor), which can change color from gray to green to blend in. Look for its slightly warty skin, large toe pads, and a dark X-shaped mark on its back. Listen for a short, musical trill. They can be confused with spring peepers, but gray tree frogs are larger and have a slower call.

A good flashlight with a red filter helps spot frogs at night without startling them. A field guide specific to amphibians of the Great Plains is handy. Bring a small notebook to record calls and locations. For a deeper dive, check out our tree frog identification hub for more tips on recognizing species across the US.

Calls are easiest to hear at dusk near permanent water bodies. Try visiting state parks like Lake Herman or Palisades in the east. Listen for a short, melodic trill that lasts about half a second. Female tree frogs prefer males with longer calls. Record calls with your phone to compare with online databases later.
