In July of this year, the U.S. Fish and Wildlife Service removed the lesser prairie chicken from the Federal List of Endangered and Threatened Wildlife. Despite the bird's removal, which was the result of a 2014 lawsuit, the USFWS acknowledges that agricultural conversion of prairie grasslands is a key threat to the lesser prairie chicken. According to the FWS, the lesser prairie chicken has lost 84 percent of its range, and further habitat loss, like that documented in the new study, threatens the survival of the species. Per the FWS, the bird needs large tracts of unaltered landscape, often exceeding 20,000 acres, for self-sustaining populations to thrive.
