This bill proposes to delist the lesser prairie-chicken (Tympanuchus pallidicinctus) from both the threatened and endangered species lists established under the Endangered Species Act of 1973. This removal would apply to all distinct population segments of the species, effectively taking it out of the Act's current protections. Additionally, the legislation seeks to amend the Endangered Species Act itself to prevent any future listing of the lesser prairie-chicken. It specifically prohibits the Secretary from making a determination that the lesser prairie-chicken is an endangered or threatened species, thereby excluding it permanently from the Act's authority.
