Sharpshooting Suburban White-Tailed Deer Reduces Deer–Vehicle Collisions

Abstract

Too many deer–vehicle collisions (DVCs) are one of the primary reasons local governments implement lethal deer management programs. However, there are limited data to demonstrate that a reduction in deer (Odocoileus spp.) densities will result in a decline in DVCs. We conducted sharpshooting programs in 3 suburban communities to reduce deer numbers and to address rising DVCs. Annual or periodic population estimates were conducted using both helicopter snow counts and aerial infrared counts to assess population trends. Management efforts were conducted from 3 to 7 years. Local deer herds were reduced by 54%, 72%, and 76%, with resulting reductions in DVCs of 49%, 75%, and 78%, respectively. These projects clearly demonstrate that a reduction in local deer densities using lethal methods can significantly reduce DVCs.
