As a former longterm working resource management person, with decades of experience in real wilderness densely populated by "apex predators" such as Grizzlies and Wolves, I have to say that the above post is incorrect in it's assertions concerning Wolve's hunting methods. This is an "old wive's tale" and Wolves DO NOT specifically prey on ANY group within a given prey population, "sick" or robust.
Other limiting factors, such as CWD, have NOTHING to do with predation and there is no clear correlation between population densities of Cervidae and the incidence of such conditions. HABITAT issues, caused by longterm "high" numbers of Whitetail Deer, more especially MULE Deer and Elk CAN exacerbate certain limiting factors, however, a linear, causative process does not exist.
A species CANNOT become ...overly prolific..., that is a misuse of the term AND, there is some evidence to suggest that, for example, "Odocoileus" DO produce MORE offspring under severe predation, rather, as suggested, the reverse.
The incidence of "disease" is also NOT dependent on the presence of or level of predation by an "apex predator", although the population levels could be affected where both disease and large numbers of predators exist.
The ...natural process to thin out the sick individuals... IS the disease, NOT a predator or even several, such as Black Bears, Wolves and Cougars, all VERY common here.
MANY ...prey species... DO NOT ...benefit... from the presence of Wolves, RM Goats is one example and in many situations, Moose and Elk are others.
I do not mean to be offensive, but, as with dealing with Grizzlies, carrying guns and the "bear spray" issue, there is SO MUCH misinformation on the backpacking forums about wildlife ecology and certain "icon " species, that I want to introduce some more factual info., based on "hands-on" experience, over several decades, with the animals concerned.
