The precise methods of accumulating study info for FDRs might be evaluated as new technologies and analyses are made. Whilst path digital camera information have boosted sample dimensions in many DMUs, the statistical strategies used to analyze this information keep on to evolve.
FDR reports are offered for viewing around the Wisconsin DNR Web-site dnr.wi.gov search term “wildlife stories”. Learn the way to engage in ODW by traveling to the DNR Site dnr.

Reduced FDRs in certain counties may possibly reflect increased amounts of predation on new child fawns and populations which can be nearer to carrying potential.
