Washington State has no idea what it's cougar population is. They claim 1500.
About 20 years ago they banned hound hunting of cougars, at that time Washington had a robust cougar population, and hound hunters were killing several hundred a year; lets say 500. It is well known that the cougar population has increased substantially in the past 20 years or so.
Let's just assume that the population hasn't gone up in the past 20 years. That would mean that hunters were killing 1/3 (500 out of 1500) of the total population annually when hounds were being used; ridiculous.
"Boot hunters" alone are now killing about 200 annually, and that isn't counting for the substantial number of SSS incidents.
I personally knew one of Washington's cat bios several years ago, the State claimed him as a lynx specialist; he was as dumb as a box of rocks; don't even get me started on that subject.
I've met that guy, quite a few years ago. Dumb as a box of rocks is giving him too much credit. I also happened to know a guy who hunts for Washington Fish and Game, he kills around 50 lions a year for them. And that is just in a couple of counties around Spokane. Of course they don't advertise that fact. I'd sold him a couple pups in the past, but won't sell him any more, because states like Washington and Oregon that outlawed hunting them with hounds should have to live with them. The voters voted to outlaw hound hunting, the government shouldn't be able to do it when the sportsman can't.
All that being said, lions while being very hard to eradicate, are one of the easiest animals I know of to hurt the population by overhunting. The only reliably successful way to hunt them is with hounds, but most houndmen realize that the population can be easily hurt and they tend to "farm" their lions (in this part of the country, in places like the sheep country of Wyoming that I hunt, they kill most of them, as the sheep ranchers really want them gone. But sheep manufacture predators, I swear, you can run traps, posion, hounds, airplanes, everything that you can think of, and if there is sheep predators will show up from the next state over.) to keep a decent hunting population.
