The volume of does aged is variable across DMUs and it really is hard to get really massive sample measurements in certain parts and specially when there are actually zero antlerless quotas.
Steps of registration compliance might be crucial as we carry on with e-registration. Increasing response costs and expanding volunteerism will also deliver much more reliable effects at a finer scale.
Deer populace measurement and trends are important for interpreting other measure of deer abundance and harvest trends.
Necessary in-particular person deer harvest registration was in place in Wisconsin Considering that the 1953 deer season.
