It would be interesting to see the results of the actual study weaver or whomever did to determine most carcasses were already consumed before the bears emerged. If it is so....then so be it, but I do question it. I couldn't find a link to Weavers article.. Especially in Yellowstone where he was referring to, where, in those days, the elk numbers were nearer 35,000 as opposed to the 6-8 or thou they now estimate. Man, you'd think there would be a lot of carcasses available, particularly in a bad winter. ???
I like to think of Joe Friday from the old Dragnet show; "Give me the facts maam, just the facts". So, let's look at some facts as they pertain to this predator-prey issue.
Wolves prey on ungulates year-round while bears feed on ungulates primarily as winter-killed carcasses and ungulate calves in spring, and weakened or injured male ungulates during the fall rut (Mattson et al. 1991). Grasses, sedges, forbs, berries, nuts, and roots comprise a large portion of a bear's diet throughout the year. After den emergence, both black bears and grizzly bears scavenge winter-killed carcasses. The availability of fewer early-winter ungulate carcasses to bears in the spring, due to wolf populations, would be little change from the present situation (Weaver 1986).
Just for the record, I've spent the past 25 years surrounded by highly intelligent research scientists who have devoted their entire lives to generating and evaluating data. So, I would say that I am somewhat "educated" on this process.
Wow SS I bet you don't like the poisoning idea much do you.
Do you? What's next?
I had a long reply written but decided to delete it and go with the shorter version. Yes, if necessary and we'll see.
#5 was a legislative mandate to manage elk "at or below" objective, not really FWP's fault.
According to this link, there was 17,900 elk in 1986.

I too like to work off of FACTS. The problem was that most of your comments, were opinions.Webster defines "fact" as: "A thing known to be true". I don't think you are saying #1 through #4 in my post are not true. Therefore, I must conclude that you just do not know what a fact is.
I take that as carcasses in general. In 1986, there most likely wasn't many ungulates killed by predators, early, in the park, that lasted over till spring. There might be more ungulates killed early-winter, now, but there's no noticeable increase lasting until spring. Meaning winter-kill, or otherwise. Their talking spring, so how do you differentiate as to time of death.
Your picking buggers.No, I'm not. They didn't address the normal late-winter killed carrion that historically was a significant protein source to emerging bears.
So in "YOUR" field, what do your colleagues think about your wanting wolves shot during whelping,and or killing pups in dens? Have you expressed your feelings to them?My co-workers are research scientists, not wildlife biologists. Our opinions on wildlife management are probably no more valid than any other knowledgeable outdoorsman. I never said otherwise, and hopefully never implied otherwise. But, our ability to interpret data and evaluate the merit of subsequent conclusions is honed through many years of training and practice. Regarding your above quote, yes I have expressed my opinions on this subject. Pertaining to the goal of rapid reduction of overall wolf numbers, noone has disagreed with my opinion on this matter. There is no "feel good" factor to this approach. I would be the first to admit that. However, the hippocritical stance of someone that would shoot gophers or marmots or prarie dogs or jack rabbits this time of year and then condemn the shooting of a female wolf with pups absolutely disgusts me.
I don't believe everything I read, nor everything that I hear, maybe you haven't been paying attention. But I did support my opinions with conclusions from a scientist, that did do several studies on the subject.
I'm not sure why studies done by the Park service are less important than those done by others. Maybe you can enlighten me.
Simple. It's called having an agenda to support. About the time the elk numbers started to crash in Yellowstone, a park service biologist from there, that supposedly was studying the problem, stated in writing that there was no scientific evidence that wolves were contributing to the decline of the elk in Yellowstone. I wish I could find that article. Maybe someone else saved it. Anyway, I just about barfed in my spaghetti when I read that. Talk about a waste of taxpayers money supporting BS research. If you read two reports on the safety of off-shore oil drilling, one from Exxon-Mobile and one from an independent, well funded research panel, which one would you believe?

1: Over the past 20 years, parts of Montana and other states have seen a precipitous decline in prey populations (I will regard this as primarily elk numbers, even though we all know that other species of prey are involved).
2: Over the past 20 years there has been a large increase in wolf numbers over this same geographic area. This results in a very strong correlation between increasing wolf numbers and declining elk numbers. But, correlations are indirect evidence, proving nothing by themselves.
3: Montana bear numbers have also increased over this time period. It is a given that they are efficient predators, especially on calves.
4: In the western part of Montana, the mountain lion tag quota has been greatly reduced over the last 10 years.
Shoots Straight--Your a biologist?
I suppose you consider a good bio is one who has the same opinion as yourself
I have meet many individuals that felt their degrees gave them a right to be arrogant, and none responsive to others opinions, concerning their fields of "expertise".
Just so happens that after living my entire life in Western Montana, it's usually a long shot that I'm wrong. Utilizing that insight is a valuable tool if a bio uses it.
