- Agricultural losses from deer exceed $600 million annually in the United States
- In the Northeastern US, deer are responsible for 79% of all timber regeneration failure
- Roughly 20 hunters die annually from accidental firearm discharges during deer season
- Falling from tree stands is the leading cause of injury for deer hunters, accounting for 36% of incidents
- 50% of tree stand accidents occur when the hunter is climbing up or down
- Wild deer are responsible for roughly 8 deaths per year via direct charging or goring
- Bucks are approximately 3 times more likely to attack humans during the mating season than fawns or does
