This legislation directs the immediate removal of the dunes sagebrush lizard (Sceloporus arenicolus) from both the threatened and endangered species lists established under the Endangered Species Act of 1973 . Additionally, the bill amends Section 4(a) of the Endangered Species Act to explicitly prohibit the Secretary from making any future determination that the dunes sagebrush lizard qualifies as a threatened or endangered species. This provision ensures the permanent exclusion of the species from the Act's regulatory authority and protective measures.
