The previous DD goals implemented in 1980 were based on 20 years of research with deer in enclosures with the 3 different stages of timber development. But 20 years of scientific research, plus 20 years of data using that system didn't justify the HR required by SCS in order to get the DCNR forests re-certified. Now DCNR is even DMAPPING wilderness areas where they have no plans to harvest timber, yet they want to artificially manipulate the deer herd.
