What do you guys think of the accounts of wolves killing grizzlies I dont believe the so called "accounts" of cougars killing grizzlies Go thru this whole thread. Bears totally dominate wolves, even wolf packs.
The accounts of cougars killing grizzlies are just anecdotes told by the Native Americans. There are no accounts of cougars killing grizzlies in the last 200 years even though the bears are smaller now. But that is for another thread.

Soon all restrictions will be lifted and wolves will be delisted across the country giving control to the states for managing their wolf population. Currently only a few states along northern Rockies are classified as delisted. Control given to the states could mean eventually hunting and or trapping seasons on Wolves to appease ranchers who have lost livestock in the past and were essentially helpless as they were required to have Game and Fish officers be present to kill offending wolves. This stirs up once again a lot of controversy as to whether the Wolf population can succeed once delisted. www.startribune.com/anderson-minnesota-s-path-isn-t-so-clear-when-wolves-are-delisted/568529752/

Wolves will probably suffer greatly and once again face near-extinction before protection returns - sadly.

Some notes from Ursus Arctos 1758 linnaeus Brown bears regularly intimidate gray wolves (Canis lupus) away from their kills, with wolves occurring in most of the brown bear's worldwide distribution. In Yellowstone National Park, brown bears pirate wolf kills so often, Yellowstone's Wolf Project director Doug Smith wrote, "It's not a matter of if the bears will come calling after a kill, but when." Similarly, in Denali National Park, grizzly bears routinely rob wolf packs of their kills. An interesting thought. With the delisting of Wolves soon coming, should the Wolf population again dwindle due to confrontations with human or livestock or even state adopted hunting and trapping seasons, how much of an affect do you think this would have on the Grizzly Bears diet. If Grizzlies are routinely stealing Wolf kills for their food such as places like Yellowstone, how much does that affect the Bears. I wonder if their is any such data on what percentage of the Bears diet is a direct result of a Wolf kill.

If Wolf numbers are reduced significantly, how does this reflect on Grizzly populations. Would the Bears just find enough alternate food sources to continue without issue or would their semi dependency on wolf kills create a situation where the Bear numbers start to drop off.
Thoughts?

I'm not sure about specific percentages, but as it happened, right about the time the park officials got the dumpster problem under control; and ended the easy lifestyle of dumpster-diving bears, the wolves were reintroduced into Yellowstone. It was thought that the weights of the bears would drastically change due to the end of the bears feeding on dumpster junk-foods. But there was little change, if any, due to the wolf-kills the bears were discovering. Now that ( or so I've heard ) wolf hunting will be once more legalized, this might drastically change the lives of Yellowstone bears - for the worse.

So in your opinion Yellowstone Bears who have become dependent on the Wolf kills would have a negative affect on the Yellowstone Grizzly population?
I guess time will tell when Wolves become de-listed across the country. It would be interesting to hear a Bear Biologists take on this subject.

I wouldn't say dependent, but better off with them than without them. More bears might perish each Winter from lack of weight-gaining proteins needed. During the years that the wolves were absent, the bears were living there. But then, they were also stealing from people. As beautiful as Yellowstone is; it is actually a very harsh environment for the bears. Another problem; more bears ( especially grizzlies ) might go outside of the park area looking for livestock and other foods provided by man-kind. Trouble.

Its allright, grizzly bears would do just fine without wolves. Yes, there would definitely be less red meat for the bears, i guess that would increase there hunting rate. But the main thing to remember is that grizzly bears are mostly omnivores, much more omnivores than carnivores percentage wise. (For example, I know that the Ussuri brown bear's meat intake is about 10-20%). I am not sure about the Yellowstone grizzly meat intake percentage but it should be the same or just a little more, but it is still more omnivorous than carnivorous. So the food habits would probably change a little but it will definitely survive with no problems.

Red meat isn't the only benefit from the wolves. Wolves keep the Elk herd in check (their main food source) which has positive benefits not only for Grizzlies but Bison as well.

Wow, thats something new to me to be very honest, i never thought about that, great find Tom. In general yeah, wolves are very positive to grizzly bears as we already know. But still, survival wise, grizzlies really dont need wolves to survive, that is my point.

Elk are grazers and browsers. If left unchecked and their numbers explode, they could likely overgraze and make it more difficult for other plant eating mammals.
