Dr. Nick Haddad is a professor of ecology and conservation biology at Kellogg Biological Station of Michigan State University. For more than two decades, he has studied the world’s rarest butterflies. He brought together insights from his and other studies on conservation of butterflies threatened by climate change and land use change in a book, The Last Butterflies: a Scientist’s Quest to Save a Rare and Vanishing Creature. He leads decades-long studies that bring scientific principles to conservation actions, including on how grassland restoration in and around croplands can increase diversity of pollinators like bees and butterflies, and how creating habitat corridors in landscapes where habitat has been lost can serve as superhighways for plants and animals and increase their populations.
