In June 2014, the Permian Basin Petroleum Association and several New Mexico counties "filed a lawsuit challenging the service’s 2014 listing," Neeley writes. "In September 2015, a court ruled in favor of the plaintiffs and vacated the final listing rule, effectively ending ESA protections for the bird. The ruling also invalidated USFWS’s rule under section 4(d) of the ESA that tailored regulations governing take of the species to focus on activities that are threats to the species’ survival."
"Once abundant across much of the five range states of Texas, New Mexico, Oklahoma, Kansas and Colorado, the bird’s historical range of native grasslands and prairies has been reduced by an estimated 84 percent, according to USFWS," Neeley writes.
