Endangered Karner Blue Butterfly Habitat Management

As part of a Federal Energy Regulatory Commission (FERC) re-licensing requirement, Consumers Energy developed a management plan for the Karner blue butterfly (Lycaeides melissa samuelis), a state threatened and federal endangered species, on two power line corridor sites.

King & MacGregor Environmental, Inc. (KME) conducted a botanical assessment and mapped wild lupine (Lupinus perennis) patches, the only food source of Karner blue butterfly larvae, in designated management units. KME assisted in the preparation of a plan to promote the growth of lupine within the study area. Methods included removal of woody vegetation and spotted knapweed (Centaurea maculosa) and planting lupine seeds, Over time, habitat monitoring will provide resource managers with a better understanding of the interactions between the Karner blue butterfly, lupine abundance and habitat structure development.

Project Highlights

  • Evaluated the distribution and abundance of wild lupine

  • Supervised plan implementation

  • Monitoring the effectiveness of treatment and Karner blue butterfly habitat development
