Alterations in deer populace estimates amongst years in the same DMU may perhaps mirror previous Wintertime severity (while in the northern DMUs, Specifically), quantity of antlerless harvest, or variation in buck harvest rates.

View the amount of deer sampled for Serious wasting condition (CWD) on a yearly basis as well as the quantity of deer that take a look at favourable. Also see the subset of deer exhibiting medical symptoms that are tested for CWD annually and what number of of such test good.
