The quantity of does aged is variable throughout DMUs and it really is challenging to get extremely substantial sample sizes in some parts, and especially in DMUs with zero website or minimal antlerless quotas.
The yearling buck percentage is approximated from growing older details of harvested bucks and is employed as an input to the formulation for yearly deer herd abundance estimation.
The adult buck inhabitants is then expanded to your entire population using estimates of the volume of does for each buck and the number of fawns for every doe while in the pre-hunt population.
