Clearly you can kill too many does sport hunting. What we have today that we didn't have in the 80s nearly as bad, is coyotes. They take a huge toll on the herds. That's getting worse, not better. Don't matter if you let the baby maker walk, if her babies aren't surviving. I have no numbers to point to on any particular piece of property, but Auburn has done plenty of research that tells us yotes are having an impact.
