The Karner blue butterfly occurs on about 3,900 acres within ten counties in Michigan and nearly 2,700 acres of that habitat is on non-federal lands. 


The Michigan Department of Natural Resources (DNR) and a number of partners prepared an Habitat Conservation Plan (HCP) so that they may continue to conduct their normal activities while conserving the the Karner Blue Butterfly and its habitat.  


The Endangered Species Act prohibits the "take" (i.e., destruction or harm) of listed species unless a permit is obtained from the U.S.Fish and Wildlife Service. The permit is called an "Incidental Take Permit" and is obtained only after an HCP is developed.  An HCP identifies how "take" will be reduced and identifies the actions that will be used to compensate for "take" that occurs. 


The Incidental Take Permit duration is 20 years and allows for take of Karner from habitat management, utility and transportation right-of-way maintenance, and certain development activities on non-federal lands in Michigan.


The Michigan DNR HCP for Karner blues identifies conservation measures that the DNR and partners will do to minimize and mitigate incidental take due to ground disturbances from habitat management, right-of-way maintenance, and development activities in Karner blue butterfly habitat.
