Searching the archives of this forum is a tedious undertaking. I'm comfortable with the methodology. If you're not and you wish to have a better understanding of how doe tag allocations are arrived at, I suggest you seek out the explanations given by RSB and others here and in the PGC reports.
You are comfortable with the methodology because you don't understand the method they are using and no one else does either , including the PGC. There are no established DD goals for a WMU that is at it's goal for herd health but has poor forest health, therefore there is no way to calculate how many deer need to be harvested to improve forest health.
Herd health is no longer a determining factor in allocating tags since the PGC has declared all WMUs but 3D are at there goal. So the PGC is claiming that the herd is being managed based on forest health and deer/human conflicts and there are no established DD goals for either criteria.
