MSY fails to consider the long term impact on habitat. By letting the deer herd max out, over time the habitat is degraded by deer overbrowsing the best forage leaving less desirable forage to regenerate.
But, the less desirable forage is still more than adequate, to maintain max. breeding rates and recruitment. That is why it is called the MSY CC.
Why did you avoid answering my question regarding what RDD you would like the PGC to use to managing the herd.
BTW, the vast majority of timber harvests in PA result in high grading. The best trees are removed and the less desirable species like beech bass and gum are left standing.
