Here’s how mule deer fawns, elk calves are fairing
Statewide, 67% of fawns and 93% of calves with tracking collars have survived through mid-March
Winter survival is typically the biggest single factor affecting mule deer herds, and the long-term average is about 60% of fawns surviving their first winter, but during hard winters that can be significantly lower. Earlier this winter, Fish and Game biologists captured and collared 173 mule deer fawns and 178 elk calves in various parts of the state to monitor herd health and track their survival throughout winter.
