Vermont's Big
Game Mammals
Mark Scott, Vermont Fish & Wildlife Department
1. We regularly refine our data collections and population models to better monitor pops and health over time. Research at higher intuitions, such as UVM, plays a critical role.
2. Key constituents (i.e. hunters), and others, expect to participate in harvesting or seeing these species annually.
3. The future of these species and forests health are interdependently connected–that’s why VMC efforts are so important.
