Conservation groups filed a notice today of their intent to sue the Trump administration for failing to protect severely imperiled lesser prairie chickens under the Endangered Species Act.

The groups petitioned the U.S. Fish and Wildlife Service to protect the birds in September 2016. The agency promised to make a decision on that protection by the end of summer 2017, but failed to do so.

“The Trump administration’s foot dragging is placing these unique, dancing birds at serious risk of extinction,” said Noah Greenwald, endangered species director at the Center. “The Endangered Species Act has saved more than 99 percent of the species under its protection. It can save the lesser prairie chicken too, but only if the birds are listed as a threatened or endangered species.”

In 2014 the Fish and Wildlife Service listed the lesser prairie chicken as threatened. But protection was overturned on procedural grounds after a lawsuit from the Permian Basin Petroleum Association and four counties.

The bird lives in Colorado, Kansas, New Mexico, Oklahoma and Texas. It is severely threatened by habitat loss and fragmentation caused by oil and gas development, cropland conversion, livestock grazing and roads and power lines.

“Listing the lesser prairie chicken as threatened or endangered is the first step toward recovering this iconic species,” said Jason Rylander, senior counsel at Defenders of Wildlife. “The lesser prairie chicken has waited long enough for Endangered Species Act protection. It’s time for the Trump administration to act.”

In addition to habitat loss, the lesser prairie chicken is threatened by climate change. The summer of 2011 saw some of the hottest and driest conditions on record in the Southern Plains, with ground temperatures exceeding 130 degrees Fahrenheit, a critical threshold above which lesser prairie chicken eggs cannot survive.

The following year prairie chicken populations plummeted to their lowest levels in decades. Overall, global warming is expected to drive a four-fold increase in the number of 100-plus degrees days on the Southern Plains.

“These incredible birds deserve better than continuing neglect from the Trump administration,” said Taylor Jones, an endangered species advocate at WildEarth Guardians. “Threats from climate change and habitat loss continue to grow, and this species needs the strongest legal protections possible to escape extinction.”

The lesser prairie chicken — an icon of the Southern Plains — once numbered in the millions but has declined to just roughly 38,000 birds across less than 17 percent of its original range. Experts estimate the population of lesser prairie chickens at 3 million birds before the beginning of Euro-American settlement on the Great Plains.

The petitioners are WildEarth Guardians, Defenders of Wildlife and the Center for Biological Diversity.
