Deer inhabitants estimates from a DMU could be when compared over time. 3-yr working averages of population dimension are actually calculated to help illustrate In general inhabitants trend. Modifications in deer inhabitants estimates between yrs in the identical DMU may reflect previous winter severity (inside the northern DMUs, especially), degree of antlerless harvest, or variation in buck harvest premiums.
The precision and repeatability of FDRs are features of the quantity of does and fawns noticed. With the DMU stage sample dimensions have at times been comparatively minimal.
