The boreal chorus frog, formerly called the western chorus frog in our state, is a small frog that may be gray or tan; it has 3 wide, dark stripes or a series of spots down the back, and a wide, dark stripe passing through the eyes and extending along the sides. A natural forest buffer of 30 m (100 feet) or more or at least the width of local tree heights should be maintained around breeding ponds if possible. The Boreal Chorus Frog lacks dorsolateral folds on its back. The areas in which Boreal Chorus Frogs have been documented should be monitored and maintained. Woody debris, rocks, leaf litter and other cover objects should be maintained to provide habitat for this species.Breeding from first week of May to second week of July.The best way to survey for Boreal Chorus Frogs is to listen for breeding calls from adult males during the breeding season. The Spring Peeper has an X-shaped blotch on the back, whereas the Boreal Chorus Frog has three stripes (sometimes broken into blotches). Habitat.

The boreal chorus frog is found in a variety of habitats, but never far from woodlands. For certain taxa, especially poorly collected or extirpated species of prairie and savanna habitats, natural community lists were derived from inferences from collection sites and habitat preferences in immediately adjacent states (particularly Indiana and Illinois). Under this stripe is a white line running the length of the lip. Connectivity between breeding pools/ponds and adjacent forested or open habitats should be maintained. Visual encounter surveys also can be conducted for adult Boreal Chorus Frogs and their tadpoles at breeding sites in the spring and summer from May until mid-July to mid-August.Survey Period: From first week of May to fourth week of May,Survey Period: From first week of May to third week of August,About the Natural Community Classification.

There also is a distinctive white or cream-colored stripe along the upper lip bordered above by a dark stripe from the nostril through the eye and along the side of the body. In many cases, the general habitat descriptions should provide greater clarity and direction to the surveyor.
