    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.

    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 desperate situation,” 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 conservation 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.

    Under the plan, for example, the agency said it would not prosecute landowners or businesses that unintentionally kill, harm, or disturb the bird, as long as they had signed a range-wide management plan to restore prairie chicken habitat. Negotiated by USFWS and the states, the plan requires individuals and businesses that damage habitat as part of their operations to pay into a fund to replace every acre destroyed with 2 new acres of suitable habitat. The fund will also be used to compensate landowners who set aside habitat. USFWS also set an interim goal of restoring prairie chicken populations to an annual average of 67,000 birds over the next 10 years. And it gives the Western Association of Fish and Wildlife Agencies (WAFWA), a coalition of state agencies, the job of monitoring progress. Overall, the idea is to let “states remain in the driver’s seat for managing the species,” Ashe said.

    Not everyone buys the win-win rhetoric. Some Congress members are trying to block the plan, and at least a dozen industry groups, four states, and three environmental groups are challenging it in federal court. Not surprisingly, industry groups and states generally argue it goes too far; environmentalists say it doesn’t go far enough. “The federal government is giving responsibility for managing the bird to the same industries that are pushing it to extinction,” says biologist Jay Lininger.

26. The major reason for listing the lesser prairie chicken as threatened is ________.

答案:

A

解析:

答案精析:根据题干中的major reason和threatened可定位至第二段首句。定位句提及The crash was a major reason的crash指首段中的小松鸡的数量由以往的200万降到2.2万只,因此选择A项。

错项排除:文章未提及草原面积被低估,因此排除B项。文章中环保主义者对将小松鸡列为濒危感到不满,所以要求相关机构采取措施,并非生物学家的态度,因此排除C项。文章中提及一些与土地所有者相关的措施,但并未说明他们的态度和观点,因此排除D项。
