Had Donald Trump been president in 1973, when Richard Nixon signed the Endangered Species Act into federal law, the Gunnison sage-grouse would be extinct. Close to 90 percent of all Gunnison sage-grouse remaining on the planet are in the Gunnison River Basin of west-central Colorado. The rest are in Utah. They’ve been extirpated from Arizona and New Mexico.
The species is critically endangered in fact, if not by official decree. It is protected by the Act as just “threatened” because the Interior Department lost a lawsuit brought by Gunnison County, the states of Utah and Colorado, and ranching, livestock and energy-development interests.
