let's face it,some of the more remote areas really don't get that much hunting pressure so what is keeping the populations low like in the south?coyotes
There is also a HUGE difference in the breeding times and fawn birth windows between the southern and northern states that influence the percentage of fawn predation.
In the southern states, since fawns donít have extreme winter conditions to contend with, does breed over a much longer period of the summer and fall. That results in the annual fawn crop being dribbled out over the entire spring and summer. Which then allows for a much longer time that coyotes can catch fawns. That in turn also keeps the coyote populations both on the hunt for fawns and also in a healthier and higher population status.
In the northern states, like Pennsylvania, the majority of doe breeding, provided you have a near natural and correct buck to doe ratio, occurs over a short six-week period. That then results in a burst or flooding of fawns hitting the ground in a shorter period of time. That short flooding of fawns means predation is not going to result in as high of percentage of loss as you get when you dribble the fawning over a longer period of time as what occurs in the southern states. That narrowing of the breeding time and fawn birth window is also why it is important to have a buck/doe ratio that results in the does being bred during their first estrus cycle.
In short you simply canít compare and extrapolate fawn predation from those southern states into anything relative, meaningful or accurate to what predation is I the northern states. There are two totally different set of influences from one area to the other that make them non-relative.
