This bill proposes to permanently remove the lesser prairie-chicken , including all its distinct population segments, from the lists of threatened and endangered species under the Endangered Species Act of 1973. This delisting would take effect immediately, overriding any other provisions of law. Furthermore, the legislation amends Section 4(a) of the Endangered Species Act to prevent its future relisting. Specifically, it prohibits the Secretary from making any determination that the lesser prairie-chicken is either threatened or endangered, thereby excluding the species entirely from the Act's protective authority.
