Nature's plan. One or two good reproductive seasons with decent cover/food in place and an area's deer numbers can nearly double.
Enough over winter browse to support healthy does means better fawn production, better chance of twin fawns. Enough good cover to allow more fawns to elude predators, more fawns make it to the point that they're less vulnerable. Result: More deer.
If it progresses to the point that deer numbers become too high, then a lack of food eventually starts another depressive cycle.
If three or more people think you're a dimwit, chances are at least one of them is right.
