The DNR asks deer hunters within Jackson and Clark counties to assist with efforts to identify where CWD occurs. Collecting CWD samples is essential for assessing where and to what extent CWD occurs in deer across the state.
CWD is a fatal, infectious nervous system disease of deer, moose, elk and reindeer/caribou. It belongs to the family of diseases known as transmissible spongiform encephalopathies (TSEs) or prion diseases. The Wisconsin DNR began monitoring the state’s wild white-tailed deer population for CWD in 1999. The first positives were found in 2002.
