The Hemorrhagic diseases are the ones to fear. 2012-2013 it killed big numbers out west. Some say 80% in South Dakota.
Most of these populations have come back. It takes years though.
Nebraska estimated 50% that year. They were close where we hunt.
But even with CWD in that area the herd is back to normal now. It rebounded in about 3 years
Until someone proves it to me otherwise, Iβm not worried about CWD affecting the deer herd.
