Tree Frogs in South Dakota: Identification Guide and Where to Start Looking

What are the most useful ID markers for tree frogs in South Dakota?

Tree frogs in South Dakota are small, typically 0.75 to 1.5 inches long. Look for expanded toe pads (adhesive discs) on each toe, which help them climb. Color varies from green to brown or gray, often matching their surroundings. The boreal chorus frog has three dark longitudinal stripes on its back, a dark eye stripe, and a white upper lip. Gray tree frogs have bumpy skin, bright yellow or orange inner thighs, and a mottled pattern that blends into tree bark. Listen for calls: chorus frogs produce a rising trill like running a finger over a comb, while gray tree frogs give a short, birdlike trill.

Which tree frog species are most likely in South Dakota?

Two species of tree frogs are possible in South Dakota: the boreal chorus frog (*Pseudacris maculata*) and the gray tree frog (*Hyla versicolor/chrysoscelis*). The boreal chorus frog is widespread across the state, especially in prairie potholes, marshes, and roadside ditches. The gray tree frog is limited to wooded areas in the eastern counties, such as along the Big Sioux River and in the Black Hills (though rare there). A third species, the spring peeper, is not found in South Dakota; it is restricted to the eastern US. For more details on tree frog species, visit ourtree frogs animal hub.

Where in South Dakota do people usually notice tree frogs first?

Most sightings and calls come from the eastern half of South Dakota, particularly in counties like Brookings, Minnehaha, Lincoln, and Union. Popular spots include the wetlands around Lake Herman State Park, the Big Sioux River floodplain, and Sica Hollow State Park. In the west, the Black Hills have limited tree frog habitat, but you might hear them in areas with permanent ponds. For a broader look at South Dakota wildlife, check ourSouth Dakota wildlife guide.

What is the best season for confident tree frog sightings?

The best time to see and hear tree frogs in South Dakota is from late March through June. This is the breeding season, when males call from water sources at night. Warm spring rains trigger movement and calling. After June, activity diminishes, though you may still spot them after summer rains. In winter, tree frogs hibernate under leaf litter or in burrows, so sightings are impossible. Focus your efforts on spring evenings for the best odds.

How can you tell tree frogs apart from similar species?

In South Dakota, the boreal chorus frog is often confused with the spring peeper (not present in state) or the wood frog (*Lithobates sylvaticus*). Wood frogs lack toe pads and have a dark mask across the eye, not stripes. Boreal chorus frogs have distinct three stripes, while gray tree frogs have a mottled pattern. Also listen: spring peepers have a high-pitched "peep" sound, not the trill of chorus frogs. Use a field guide to confirm. The key is toe pads and stripe patterns.

Where are the best places to spot tree frogs in South Dakota?

Top locations include Newton Hills State Park (Lincoln County), Big Sioux River wetlands near Brandon, and Sand Lake National Wildlife Refuge (Brown County). Also try the floodplain forests along the Missouri River in the southeast. At night, use a flashlight to spot eye shine from frogs sitting on cattails or low branches. Walk slowly near water edges. Remember to minimize disturbance. For real-time conditions, check local forums.
