EARLIER this month, the United States Fish and Wildlife Service announced it would designate “critical habitat” for the endangered jaguar in the United States and take the first steps toward mandating a jaguar recovery plan. This is a policy reversal and, on the surface, it may appear to be a victory for the conservation community and for jaguars, the largest wild cats in the Western Hemisphere.

Times Topics: Endangered and Extinct SpeciesBut as someone who has studied jaguars for nearly three decades, I can tell you it is nothing less than a slap in the face to good science. What’s more, by changing the rules for animal preservation, it stands to weaken the Endangered Species Act.
The debate on what to do about jaguars started in 1997, when, at the urging of many biologists (including me), the Fish and Wildlife Service put the jaguar on the United States endangered species list, because there had been occasional sightings of the cats crossing north over the United States-Mexico border. At the same time, however, the agency ruled that it would not be “prudent” to declare that the jaguar has critical habitat — a geographic area containing features the species needs to survive — in the United States. Determining an endangered species’ critical habitat is a first step toward developing a plan for helping that species recover.
The 1997 decision not to determine critical habitat for the jaguar was the right one, because even though they cross the border from time to time, jaguars don’t occupy any territory in our country — and that probably means the environment here is no longer ideal for them.
In prehistoric times, these beautiful cats inhabited significant areas of the western United States, but in the past 100 years, there have been few, if any, resident breeding populations here. The last time a female jaguar with a cub was sighted in this country was in the early 1900s. (Jaguars — the world’s third-largest wild cats, weighing up to 250 pounds, with distinctive black rosettes on their fur — are a separate species from the smaller, tawny mountain lions, which still roam large areas of the American West.)
Two well-intentioned conservation advocacy groups, the Center for Biological Diversity and Defenders of Wildlife, sued the Fish and Wildlife Service to change its ruling. Thus in 2006, the agency reassessed the situation and again determined that no areas in the United States met the definition of critical habitat for the jaguar. Despite occasional sightings, mostly within 40 miles of the Mexican border, there were still no data to indicate jaguars had taken up residence inside the United States.
