The Wisconsin Department of Natural Resources (DNR) announced plans to authorize the incidental take of the starhead topminnow, a state-endangered fish species, during the IH39/90/94 Phase 3 and 4 construction project in Columbia County, according to a statement on the department’s website. An incidental take refers to the unintentional loss of a threatened or endangered species that does not endanger the survival of the overall population.
As per the Wisconsin Department of Natural Resources, the Department of Transportation’s project involves replacing and expanding the I39/90/94 bridge over the Wisconsin River, where the starhead topminnow is present. To reduce harm, the DNR will require conservation measures such as installing barriers to protect the project area and relocating fish to safe habitats. The construction plan also includes removing and adding bridge piers while minimizing potential effects on the fish population.
The measures included in the Incidental Take Authorization are sufficient to prevent major impacts on the species or its habitat. The agency’s Jeopardy Assessment and related documents are available for public review to ensure transparency in the decision-making process.
DNR conservation biologist Stacy Rowe stated that the project is not expected to jeopardize the survival or recovery of the starhead topminnow or other species in the ecosystem.
