Alloutdoors, I've got one little point to make counter to what you're saying. Realistically, a 1:1 ratio of bucks to does or bulls to cows (if we're talking elk) is very rarely achieved even in a nonhunted population. Most wild ungulate populations will arrive, sans hunting, at a ratio between 4 and 8 males per 10 females. First reason, in fact, it is rather more common for the birth ratios to favor females over males. (For instance, here in western MT, for the past decade, elk fetus studies have shown a 38:62 ratio of males to females.) It's been shown scientifically that deer populations under carrying capacity will spit out more does than bucks in the fawn population, and that populations over carrying capacity will spit out more bucks than does. Secondly, males suffer a greatly higher natural mortality rate than females even without hunting. This extra mortality largely rises from the fact that the rut is pushed up against winter, so the males are worn to a frazzle going into winter. Secondly, as the male:female ratio rises toward 1:1, you can get significant battle mortality during the rut.

I'm not at all opposed to QDM, but we need to understand that a true 1:1 ratio is really not natural. Thus, it may be impossible to attain, and may be undesirable to attain.
