"No one said it was.It doesn't matter though,the area inside the fence regenerated because it wasn't being browsed."
Because there are not deer! lmao. UNNATURAL conditions! Is that an acceptable goal? lol.
"The outside did not fail because of soil,competing vegitation,lack of light or acid rain."
Sure it did....under NATURAL CONDITIONS with DEER existing lol. Because of the above factors and more. LIke timbering practices etc...
The exclosure would also eliminate size of cut from the equation. A small cut would be more effected by deer than a larger one. Though it doesnt make one bit of difference inside that fence in "unnatural" conditions. Those same unnatural conditions also wouldnt rule out altered growth rate due to soils which would cause some specieds to stay in the deer browse zone far longer, and also others to not recover as quickly from browsing. There is also nothing saying that the ferns werent sprayed inside the fence, but its pretty clear they werent on the outside! lol.
