The U.S. government announced protections Thursday for two populations of a rare prairie bird that's found in parts of the Midwest and Plains.
The lesser prairie chicken's range covers a portion of the New Mexico-Texas state line and extends into parts of Colorado, Oklahoma and Kansas. The habitat of the bird, a type of grouse, has diminished across about 90% of its historical range, officials said.
"The lesser prairie-chicken's decline is a sign our native grasslands and prairies are in peril," said Amy Lueders, Southwest regional director at the U.S. Fish and Wildlife Service.
The crow-size, terrestrial birds are known for spring courtship rituals that include flamboyant dances by the males as they make a cacophony of clucking, cackling and booming sounds. They were once thought to number in the millions, but now, surveys show, the five-year average population across the entire range hovers around 30,000.
Environmentalists have sought stronger federal protections for decades. They consider the species severely at risk due to oil and gas development, livestock grazing, farming and the building of roads and power lines.
Some in Congress said greater protections weren't needed and the government instead should rely on voluntary conservation efforts already in place. Kansas' newly elected attorney general promised to challenge the Fish and Wild Life Service's decision in court once he takes office in January.
The decision covers the grouse's southern population in New Mexico and the southern reaches of the Texas Panhandle, where they are considered endangered, and their northern range, where they received the less severe "threatened" status. The rule takes effect in late January.
Landowners and the oil and gas industry say they have had success with voluntary conservation programs aimed at protecting habitat and boosting the bird's numbers.
The federal government in 2014 classified the bird as a threatened species, but was forced to reverse that two years later after court rulings determined the agency didn't properly consider the voluntary conservation efforts.
"In their final rule, the U.S. Fish and Wildlife Service first commended landowners' voluntary efforts to increase lesser prairie-chicken populations in Kansas, and then unilaterally decided that the federal government is better equipped to address these local areas," Kansas Rep. Tracey Mann of Kansas said in a statement.
A 2014 Kansas law says the state has the sole power to regulate the species — along with the larger, darker and more abundant greater prairie chicken — and their habitats within state limits. It authorizes the attorney general or county prosecutors to sue over any federal attempt to enforce conservation measures.
