Here is what Dr. deCalesta had to say about predation on a QDM property in 2f.
Each doe should produce 1-2 fawns every year, but it took approximately 2.3 does to bring one
fawn to fall recruitment in 2005. Research recently conducted in Pennsylvania by the Pennsylvania
Game Commission and Pennsylvania State University suggests that predators (primarily black bear
and coyotes) kill about half of the fawns prior to fall; it is reasonable to assume that the same
predation rate exists on the KQDC where bears and coyotes are plentiful. If this predation rate is
representative, then without predation by bears and coyotes each doe should have brought about 1.15
fawns through to fall, which is closer to the desired 1-2 fawns per doe.
I suppose that proves beyond a doubt that Alt's claims about a decreased breeding window would overwhelm the predators was pure horse puckey
