That said, be careful what you ask for. This flip side of this study is that if you want to save X calves per year in an area, you only have to remove 1/2 to 1/4 of the bears we previously thought.

If you had cameras everywhere in the state during calving season you would find coyote and bear numbers need to be reduced drastically. Back in the 80's I rarely saw Bear/Cougar tracks anywhere. Now I see them everywhere. Coyote tracks were common but nothing like they are now in some places.Being a trapper I have always looked for tracks and still do.
Was the good old days when deer were more prevalent in the Methow.

Now I see them everywhere. Coyote tracks were common but nothing like they are now in some places.Being a trapper I have always looked for tracks and still do.The point Stein was trying to make (I believe) is that if a single bear is killing 2-4 times more fawns/calves than we thought, fewer individuals need to be removed to bring the depredations back down.This study has been floating around for a while. I think an idea that hasn't been explored as far as season-setting goes is targeting bear seasons more towards spring, when calves/fawns are dropping. Reducing numbers at that critical time is likely to have a bigger survival impact than reducing numbers in the fall.
I watched a few documentaries on Yellowstone and bears and that's what they discussed/showed, bears targeting calves, but they called it minimal impact and a minimal diet that didn't affect the herds.

I saw a really interesting documentary on the fall of the yellowstone herd where some long time Yellowstone biologists were putting forth a theory that wolves weren't so much to blame for the elk decline as many people think. They traced back a few decades when yellowstone Lake had an amazingly robust Brook trout population and the bears would gorge on spawning brook trout. Them$ someone illegally dumped lake trout in there. Fast forward to now and streans that used to overflow with Brook trout are now empty. The lake Trout flat wiped them out. And Lake trout spawn in the lake. These guys had been in Yellowstone a loing time and pointed to places that griz would always come to gorge on trout. But there are none. They said that Griizz have a finite home range and $any switched to elk calves. So even the same number of griz now kill a ton more elk. Io don't know, but they made a compelling argument.

Yes Dan-o, thats right. When we were there in the spring we did some fishing at Yellowstone lake they had no limit on lake trout, the person at the lodge basically said what you had heard, someone had dumped lake trout in the system, they are hardy eaters(even canibilistic if I remember right ) and took a huge toll on native species. They said the bears(needing protein) started to go after other sources like fawns, calves etc. more than they have in the past. They told us predation on park animals by bears was up because of the fish problem, this was 3 years ago

Put the kool aid down and step away from the Hillary posters.
