Tree frogs are present in South Dakota but are most likely spotted in wetlands and woodlands across the eastern half of the state. The gray tree frog is the most common species. Your best odds come after warm spring rains when males call from shrubs and trees.
1. Where are people most likely to notice tree frogs in South Dakota?
Your best odds for spotting tree frogs are in the eastern third of South Dakota, especially in the Missouri River bottomlands and the Glacial Lakes region. Look near ponds, marshes, and forest edges. Gray tree frogs (Hyla versicolor) are the most widespread. They cling to tree bark, porch lights, and window screens on humid summer nights. Start atSica Hollow State Parkor the [Lake Vermillion Recreation Area].
2. What season or weather patterns help with tree frog sightings?
Spring and early summer are prime time. Gray tree frogs start calling in May after evening temperatures stay above 50°F. The best nights are warm and damp, especially right after a thundershower. Males climb into low branches to call, and you can follow the sound. During dry spells they retreat to tree hollows or under bark, making them harder to spot.
3. How can you tell a tree frog from other small frogs in South Dakota?
Gray tree frogs have large toe pads, bumpy skin, and a dark cross-shaped mark on their back. Their color shifts from gray to green to brown based on background and temperature. Compare with the boreal chorus frog (smaller, smoother, three dark stripes) and the spring peeper (tiny, X-shaped back mark). Check ourtree frog identification hubfor side-by-side photos.

4. What are the best specific locations for tree frog watching?
Besides Sica Hollow, try the [Newton Hills State Park] near Sioux Falls, the [Lacreek National Wildlife Refuge] in the southwest, and [Oakwood Lakes State Park] in the east. All have accessible wetland edges. Walk slowly with a red-light flashlight; tree frogs often freeze in the beam, giving you a good look. Timing is key: target May to July around dusk.
5. Can you find tree frogs in backyards in South Dakota?
Yes, especially if you have a pond or rain garden. Gray tree frogs are attracted to lights that draw insects. If you live east of the Missouri River, put up a small water feature and let a section of your yard grow wild with native shrubs like dogwood or sumac. You might hear them calling from your gutters after a rain.
6. What time of night should you go searching?
Start about 30 minutes after sunset. Calling activity peaks in the first two hours of darkness. On very warm nights they may call intermittently until dawn. Use a headlamp with a red filter to avoid spooking them. Listen for a high-pitched trill that lasts about half a second, repeated every few seconds.
7. Do any South Dakota tree frogs have conservation status?
The gray tree frog is common and has no special status. The western chorus frog (which some call a tree frog but is actually a different family) is also widespread. However, the [boreal chorus frog] is listed as a Species of Greatest Conservation Need in South Dakota. If you see a very small frog with three dark stripes, it's likely that one, and records are valuable. Report sightings to the South Dakota Game, Fish and Parks.
8. How can you photograph tree frogs without disturbing them?
Use a macro lens and a flash diffuser, or shoot with a smartphone through a pair of binoculars. Approach slowly from the side, not directly overhead. Avoid touching them: their skin absorbs chemicals easily. If you want to share your interest, wear ourTree Frog T-Shirton your next outing.
