These a number of models could and did have diversified seasons, antlerless allow degrees, and harvest targets. For that reason, comparison of harvest information ahead of 2014 and beyond really should be finished with warning.

Deer population dimension and trends are important for interpreting other measure of deer abundance and harvest trends.

The Wisconsin DNR continues to search for different solutions to Price-efficiently monitor changes in deer populace dimensions in DMUs. A much better knowledge of aspects affecting buck harvest charges may Enhance the precision of harvest-primarily based inhabitants estimates.

The precise ways of gathering survey data for FDRs can be evaluated as new technologies and analyses are made. Even though trail digital camera data have boosted sample sizes in lots of DMUs, the statistical procedures employed to analyze this details continue on to evolve.
