Today my dad and I were invited by Dr. Heather Keough of the Federal Forest Service to help count the Karner Blue Butterflies that live in the Manistee National Forest. The Karner Blue Butterflies are an endangered species. Dr. Keough and her team are trying to re-grow the Michigan savannah so that the rare creatures can reproduce naturally.
