Leafy Prairie-Clover: This plant is located in only three areas: central Tennessee, north-central Alabama, and north-eastern Illinois. Leafy Prairie-Clover populations are being lost due to poor management skills as well as competition from invasive species, rock quarrying, and over-collecting. But thanks to a partnership between the Forest Service and the U.S. Fish and Wildlife Service, the Leafy Prairie-Clover is making a comeback.
