Biologists race to clear a path to survival for Northwestern cougars

Cougars have been under siege in the United States since the arrival of European settlers, victims of extirpation campaigns and habitat destruction as inhabitants converted wilderness to farmland and pasture. These campaigns eliminated Puma concolor in the East (save for a remnant population in Florida) during the 1880s, and now the same forces—abetted by good intentions—are threatening existing populations in Washington State. A new story in this week’s issue of the open-access journal PLoS Biology shows that good intentions are no substitute for sound science.

Over the past decade, Washington State’s cougar population—already under attack by developers, hunters and hostile ranchers—has come under “friendly fire” from well-meaning voters as well. Ironically, a ballot initiative to ban the traditional practice of hound hunting—and, it was assumed, to protect the state’s cougars—has served only to further endanger its few thousand remaining animals.

In “No Place for Predators?,” PLoS Biology senior science writer/editor Liza Gross shows how good intentions have paved the way to increased dangers for the Pacific Northwest’s embattled cougar population, and how wildlife biologists are scrambling to find a science-based path to coexistence between people and predators—before it’s too late.

“Contrary to popular belief,” she reports, “and the rationale behind legislation authorizing emergency and public safety hunts,” the hound-hunting ban did not yield a population spike. The hopes of Washington’s voters, it turned out, were as unfounded as the fears of its ranchers, many of whom, relying on hearsay and anecdotal evidence, insisted the big cats’ numbers were growing. “As complaints were going up, the population was tanking,” explains Rob Wielgus, director of the Large Carnivore Conservation Laboratory.

Like other researchers investigating the reality of predator management in the Pacific Northwest, Wielgus has found that perception is often at odds with the science—and that false assumptions benefit neither the state’s people nor its predators. “We’re learning all kinds of things that are counterintuitive,” he says.

As he and his scientific colleagues make clear, that new knowledge—and biologists’ ability to communicate it to the public and elected officials—may hold the key to cougars’ survival.

  It isn't just the cougar that are affected, it is also the bear. While I am not a biologist to know if the number of bear is actually decreasing like they say the cougar numbers are, I suspect the bear population is dwindling also. I can't tell you how many friends, family members, and even ME, have been affected by the increase in bear and cougar infringing on residential property. About 10 years ago a friend of mine had moved to a rural area, and I warned him not to let the kids play by the creek at the back of his property because there was cougar in the area. He laughed his head off and told me I was out of my mind. Well a couple months later he appologized and told me this story about finding the neighbors cat in an upstairs room 3 times in about a 5 or 10 minute period. Well, the third time as he tossed the cat out the back door, he turned on the porch light to figure out how the cat was getting into the 2nd story window. In midd toss (of throwing the cat out) he saw the cougar in his back yard, and proceeded to watch this poor cat crawl up the siding to get away from the cougar.
  
  This has been a problem for so many years now it is ridiculous. Legislatures need to wake up and listen to the people. Washington state citizens have been complaining ever since legislation changed the hunting laws. If you are having to go on cougar and bear hunts because peoples lives are at stake, of course the population is going to diminish. Bear and cougar MUST fear man, or man will have to kill them when they lose their fear and start living in residential areas.
  
  Nice to read that something may finally be done about this problem. It has gone on far too long.
