BB,from your own qoute that you threw back at Doug.

When densities exceed 30 deer per square mile, deer obtain enough nutrition from plant species resistant to high deer densities to maintain body condition and a high reproductive rate: this point is likened to “nutrition carrying capacity.” When deer densities are this high, significant reductions in plant diversity, vertical habitat structure and species composition occur.

Now BB,read the last line again from your qoute.

When deer densities are this high, significant reductions in plant diversity, vertical habitat structure and species composition occur.

After significant reductions in plant diversity. What happens next?
