Oak savannas support a diversity of insects, including the federally endangered Karner blue butterfly (Plebejus samuelis). This butterfly is found in oak savannas and oak-pine barrens where its only host plant, sundial lupine (Lupinus perennis) grows. The Karner blue is inextricably linked to lupine, a disturbance-dependent perennial legume that thrives on sandy soils. At Michigan Natural Features Inventory, we work to understand how the species responds to habitat management and succession to inform conservation actions.
