Deer population estimates from the DMU is usually as opposed as time passes. Three-calendar year running averages of inhabitants dimensions are already calculated that can help illustrate Over-all populace craze. Adjustments in deer population estimates among decades in the exact same DMU may possibly mirror prior Wintertime severity (from the northern DMUs, Specially), quantity of antlerless harvest, or variation in buck harvest rates.
Look at the volume of deer sampled for chronic losing disorder (CWD) every year plus the range of deer that check constructive. Also watch the subset of deer exhibiting medical signals that are examined for CWD each and every year and the quantity of of such test good.
