Crystal Darter (Crystallaria asprella), listed as a Species of Concern by the US Fish and Wildlife Service and Endangered in Wisconsin, prefers clear to slightly turbid waters over sand substrates. This darter is most often found in moderate to strong currents in large rivers where they occupy sandy riffles, bars, and pools. Spawning occurs from mid-May through mid-June.

 
 
 

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.
