Conservation agreements with the states of Texas and New Mexico have led the federal government to put off listing the dunes sagebrush lizard as an endangered species. The agreements were hammered out by state officials in an attempt to avoid disruption of drilling in West Texas oilfields after they commissioned scientific studies that did not support listing the species as endangered. The voluntary program will affect about 250,000 acres of the Permian Basin. Officials with the U.S. Fish and Wildlife Service will monitor the lizard’s progress on a yearly basis and could propose an endangered status again if they feel the need.
