OK, for all of you who don't think that whitetails affect the muley population, I took the time to look it up.
This is from MULE DEER COUNTRY by Val Geist. For those of you who don't know who Geist is, he's a Canadian biologist who is considered the foremost expert on hooved ungulates (sp??), especially Mule deer and Bighorn Sheep. It's a long chapter, so I've pulled out the important parts.
Here it is:
Page 163 "For all its current abundance, the mule deer, so different, so uniquely American, so young and promising, is nevertheless a species marked for extinction. That may be its fate in the long run. Either the white-tailed deer or man may cause that extinction.
...Mule deer show signs of dwindling wherever they meet whitetails, even in the mule deer's stronghold of Wyoming...
...[parasites] can only compete in the destruction of mule deer along with a much more potent factor. That factor is one-way hybridization."
One-way hybridization (in my words): Geist goes on to explain at length one-way hybirdization, so I'll sum it up. Basically, what he is saying is that one-way hybridization occurs when one species can breed another's females, but not the reverse.
Geist says that the mating habits of each deer allow white-tails to breed mule deer does because muley does do not play "catch me if you can" in the way that whitetails do. On the other hand, muley bucks are not fast enough in most habitats to catch whitetail does.
This results in lost fawns for mule deer because in overlapping ranges, white tails can breed muley does while mule deer cannot breed whitetail does. To add some of my own observations, mule deer are more suceptable anyway because they go into rut sooner; the whitetail bucks that are waiting for the rut are eager breed and increase competition to mule deer bucks until the start of the whitetail rut.
The only advatage mule deer have is that Geist notes they usually win against whitetails of the same age class when fighting.
He notes that this alone is not the problem entirely. Humans play a part in the creation of hybrids, beleive it or not.
Geist talks about how mule deer are easier to kill than whitetails of the same age until they are both about 4 1/2. During this time, hunters kill a good number of the bucks that should be breeding does, and mature bucks are not in enough surplus to service all does that go into heat. That leaves the small bucks to breed the does, which is fine except for the fact that then whitetail bucks are then able to win fights for mule deer does and breed them.
So you may ask, "What about the hybird fawns, if they are bred by mule deer for the next several generations, then what is the big deal?" Geist says that hybrid fawns rarely survive once they leave their mother because they don't fully use white-tail defense mechanisms or don't fully use mule deer mechanisms. They soon fall to preditors.
His last line of the chapter states, "In the meantime, however, we can assuredly expect mule deer will continue to lose ground to the whitetail."
I don't think it gets any clearer than that.
So there it is, for all of you doubters. I understand if you didn't believe me, but if you don't believe Geist, then I can't debate with you any more because you're too ignorant to comprehend both sides of the issue.
Do you still want whitetails in mule deer country?????
