It isn't just about the deer being healthy.It's about the deer continueing to dmage the habitat even more.20 DPSM is reasonable once the habitat recovers.Alot of areas have more than that now.
But it doesn't matter how much the habitat recovers the PGC will not allow the herd to increase to that density because 20 DPSM will adversely effect regeneration of commercially valuable timber species.
It never was about the deer being healthy because they were healthy when we had 1.6 M deer, in 2000.
