There is no way 2A has 40 deer per square mile!
Have you joined the ecoflakes and liars on the BOC or what?
Could it be that you missed the fact that the 40DPSM was the PS DD not the OWDD. A density of 40 PSDPSM equates to a density of only 6.25 DP 100 acres. How many beef catle would a farmer hve on 100 acres of pasture/ I guarantee it wouuld be more than twice that number and beef cattle are much larger and more selective than deer.
