Commencing the CWD Chronicles: An overview of the disease & the Issues we’ll cover for this series.

Matt Dunfee is a career CWD expert and in this episode he walks us through everything from the discovery of the disease to how its affecting deer populations today. Along with a deep dive into the biology of CWD, we talk about the responsibility that hunters have and the fears they face around CWD. Join us for this incredible primer on what’s happening out there and what needs to be done about it.
