I think a lot depends on what other species are present and what you expect out of those others.
220 (depending on survival) in year 2+ will require tremendous forage support and to me, needs to be culled down to 25-30 per acre over a period of time to have good, continued growth rates.
if 175 survive, other changes will occur that will show up over time. Condition of the HSB should be a good indicator of them having what THEY need. Population structure and sizes of other species will change as well.
