Both of those employ mechanical assistance in propelling arrows.
In Fairfax, the management program is aimed at controlling the number of white-tailed deer on public parklands, estimated at two to five times the optimum.
Goals include protection of human health and safety, curbing environmental damage, conserving biodiversity and maintaining the health of resident deer.
As deer populations have grown in many areas, concerns have risen about the dangers of collisions with cars. Fairfax officials said the county’s first fatal deer-car collision was in 1997. A deer-management program was ordered the next year, and use of archery is only one part of it.
The archery program runs from Saturday through Feb. 23.
Archers must meet strict standards, and the county said the program has proved safe.
