The Spring Peeper is a small (3/4 - 1 1/4 in.) chorus frog. The head, body and limbs are light brown in background color and the underside is yellowish. A characteristic dark x-shaped mark is evident on the back. Kansas is at the western edge of this frog's continental range. Its current probable distribution within the state is restricted to the eastern tier of counties. The Spring Peeper requires small ponds and wetlands having abundant emergent aquatic vegetation and located within or very near woodlands. This frog was formerly reported from Leavenworth County.

Spring Peepers are protected by the Kansas Nongame and Endangered Species Conservation Act and administrative regulations applicable thereto. Any time an eligible project is proposed that will impact the species' preferred habitats within its probable range, the project sponsor must contact the Ecological Services Section, Kansas Department of Wildlife, Parks and Tourism, 512 SE 25th Ave., Pratt, Kansas 67124-8174. Department personnel can then advise the project sponsor on permit requirements.
