Improvements in deer populace estimates among the a long time in precisely the same DMU could mirror prior Winter season severity (during the northern DMUs, In particular), number of antlerless harvest, or variation in buck harvest prices.
The precision and repeatability of FDRs are functions of the amount of does and fawns noticed. For the DMU degree sample measurements have sometimes been comparatively very low. It might be tricky to gather suitable sample sizes in DMUs with few full sq. miles or a sizable proportion of urban and suburban land sorts.
Data from harvest registration and getting old, in addition to other facts, is Utilized in a mathematical population product known as the Intercourse-Age-Destroy (SAK) formulation.
