Normal FDRs range across Wisconsin, commonly lower in forested areas than in farmland locations and higher after delicate winters during the north.

The three-calendar year typical demonstrates the development in yearling doe percent. Yearling doe share is mostly applied as an enter to the system for estimation of herd size with the DMU degree.  

County group FDRs from SDO surveys carry on to become a valuable way to track regional trends in deer recruitment. Any long term wants are exploratory to help in knowing what mechanisms may very well be driving the noticed trends.
