Fawn to doe ratios and yearling buck percentages are utilized to aid estimate the deer herd measurement per year which is the starting point for setting antlerless harvest quotas.

The precision and repeatability of FDRs are features of the amount of does and fawns observed. For the DMU level sample sizes have sometimes been somewhat very low. It could be hard to accumulate sufficient sample sizes in DMUs with handful of overall sq. miles or a significant proportion of city and suburban land sorts.  

FDRs are used for checking deer population standing because they offer details about fawn production and survival which might be driven by the nutritional ailment from the inhabitants.

The proportion of yearling does between Grownup does is a superb estimator of the rate at which Grownup deer are being extra to the populace which metric is fairly unaffected by harvest charge.  

The volume of does aged is variable throughout DMUs and it really is challenging to get very massive sample measurements in certain places and particularly when there are actually zero antlerless quotas.  

Measures of registration compliance is going to be critical as we go on with e-registration. Increasing reaction premiums and growing volunteerism may even produce more reputable effects in a finer scale.

Most harvest and hunter survey stories are offered for viewing around the Wisconsin DNR Web site dnr.wi.gov search phrase “wildlife experiences"
