If deer had only striped maple they might survive but they probably wouldn’t be able to produce enough surviving fawns to ever increase their population and maybe not even sustain their population with modest adult mortality.
No where in the state are deer limited to only striped maple. Furthermore studies show that an over browsed forest of beech ,birch and striped maple can support 40 DPSM at the MSY carrying capacity. Therefore the habitat in the pic could probably support at least 40 DPSM on a sustainable basis.
