Paragraph 1

Biologists estimate that as many as 2 million lesser prairie chickens—a kind of bird living on stretching grasslands—once lent red to the often gray landscape of the midwestern and southwestern United States. But just some 22,000 birds remain today, occupying about 16% of the species’ historic range.

Paragraph 2

The crash was a major reason the U.S Fish and Wildlife Service (USFWS) decided to formally list the bird as threatened. “The lesser prairie chicken is in a desperatesituation,” said USFWS Director Daniel Ashe. Some environmentalists, however, were disappointed. They had pushed the agency to designate the bird as “endangered,” a status that gives federal officials greater regulatory power to crack down on threats. But Ashe and others argued that the “threatened” tag gave the federal government flexibility to try out new, potentially less confrontational conservations approaches. In particular, they called for forging closer collaborations with western state governments, which are often uneasy with federal action and with the private landowners who control an estimated 95% of the prairie chicken’s habitat.
