This make sense why there are very low numbers of 5-7 year deer. Hunters and EHD get the rest. My question: Why are mites number higher after 5 or so period of years. I wish he mentioned odds of survival. One of 10, 100 1000 etc. I believe there is a mite cycle that causes EHD more than drought. We have dry hot summers almost every year. Some just a little dryer.
