Reduced FDRs in certain counties may well replicate better amounts of predation on newborn fawns and populations which might be closer to carrying capability.
Sample sizes for a few of the inputs from the SAK formula are limited. Therefore, it's important to pool knowledge in excess of a number of DMUs and/or a long time to supply annual deer inhabitants estimates for all DMUs.
