Karner blue butterflyHabitat Conservation Plan

Karner blue butterfly HCP Partners in Protection logo

Wisconsin’s Karner Blue Butterfly Habitat Conservation Plan (below) is the document that accompanies the incidental take permit [PDF] from the U.S. Fish and Wildlife Service to the DNR. The permit and the plan are designed to protect and conserve Karner blues while allowing activities to occur that could impact Karner blues or their habitat. The first 10-year plan was approved in 1999 and the second 10-year plan was approved in 2009.

Karners and their habitat

The long-term viability of Karner blue butterfly populations depends on habitat disturbance. Without periodic disturbance, natural woody succession shades out wild lupine and nectar plants and can passively eliminate Karner blue butterfly populations. Fortunately, many HCP partner and management activities (such as those used in forest management and utility right-of-way maintenance) provide the necessary habitat disturbances to maintain Karner habitat on the landscape. Although HCP partner management activities may result in some Karner mortality, the absence of short-term disturbance would result in greater long-term losses of Karners and their habitat.

HCP partners

The HCP currently has over 40 partners [PDF] across the state. HCP partners agree to follow specific protocols to avoid and minimize impacts to Karners during the course of their work. In return, the HCP extends permit coverage allowing them to conduct activities that may inadvertently "take" (harass, harm or kill) the federally endangered Karner blue butterfly. The level of take under Wisconsin’s HCP does not threaten the long-term survival and recovery of Karners in the state.
