The facts and history of the deer in both forestland and highly mixed farmland or residential areas all clearly do show that high deer populations can’t be sustained long term without a healthy forest. Yes the farmland, neighborhood habitats can sustain deer in a healthy conditions but history has proven that unless there is also a good mix of healthy forest in that habitat equation the high deer numbers will be sustained long term.
That simply is not true and you can't provide one bit of factual evidence that 2B , 5C and 5 b couldn't support their current high deer densities for ever. until you can provide evidence to support your claim ,everything else is just plain horsepuckey.
Now ,just in case you are suffering from a lapse of memory , re,e,ber the extended carrying capacity of valley forge and Gettysburg, which proves beyond a point you have no idea what you are talking about.
