So, fawn survival rates are pretty much a matter of the habitat being able to support more deer or not. If the habitat can’t support more deer it is a blessing for the future of the species if a higher percentage of the fawns fall victim to predation.
Fawn survival rates have nothing to do with the ability of the habitat to support more deer. In every WMU ,the harvest by hunters determines how many deer survive to the following year and that in turn determines how many fawns are recruited into next years herd.
