MADISON -Improvements to a ramp on Interstate 43 in Walworth County may result in the "incidental taking" of a rare plant under an authorization the Department of Natural Resources proposes to issue for the project. Incidental take refers to the unintentional loss of individual endangered or threatened animals or plants that does not put the overall population of the species at risk.

The Wisconsin Department of Transportation is planning an I-43 project is to address the deteriorating pavement, extend the service life of the highway pavement, improve safety, and address ongoing deterioration with the existing structures along the corridor. Specifically, at the WIS 67 interchange, project activities include grading, ditch capacity improvements, and culvert pipe replacement to improve drainage. In addition to the drainage improvements, the interchange ramps will be milled and resurfaced and the existing gravel shoulder, which is eroded, will require supplemental gravel be added to it.

The presence of the state threatened seaside crowfoot (Ranunculus cymbalaria) has been confirmed in the vicinity of the project site. DNR staff determined that the proposed project may result in the incidental taking of some plants.

Department staff concluded that the proposed project will minimize the impacts to the species by adhering to conservation measures; is not likely to jeopardize the continued existence and recovery of the state population of the species or the whole plant-animal community of which it is a part; and has benefit to the public health, safety or welfare that justifies the action.

The conservation measures to minimize the adverse effect on the threatened species will be incorporated into the proposed Incidental Take Authorization. Copies of the jeopardy assessment and background information on the seaside crowfoot are available by searching the DNR website for incidental take public notice or upon request from Stacy Rowe (608-266-7012 or The department is requesting comments from the public through June 6, 2019 regarding project-related impacts to the seaside crowfoot. Public comments should be sent to Stacy Rowe, Wisconsin DNR, PO Box 7921, Madison, WI 53707-7921 or
