Counties with Mapped NHI Occurrences

Queensnake (Regina septemvittata), listed as Endangered in Wisconsin, prefers clear warm-water streams and small rivers. This crayfish specialist is typically associated with moderate to fast water flows and rocky substrates. They also utilize shoreline habitats for basking. Queensnakes overwinter in crayfish burrows but also in artificial structures such as cracked bridge abutments, old dams, and seawalls. They are active from early-April through October and breed mid-May through mid-June. Live young are born in August or early-September. See the species guidance document for avoidance measures and management guidance from the Natural Heritage Conservation Program.


Species of Greatest Conservation Need (SGCN) are associated with habitats (or natural communities) and places on the landscape. Understanding relationships among SGCN, natural communities and ecological landscapes help us make decisions about issues affecting SGCN and their habitat and how to respond.

Conservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the Wisconsin Wildlife Action Plan because lack of information can threaten our ability to successfully preserve and care for natural resources.
