I just spoke to Princeton's animal control officer, who told me that Princeton township's deer control program has markedly reduced the number of auto accidents involving deer. When the program was started, around 2000, there were 346 accidents involving deer. The number of accidents has been dropping since then, and has leveled out over the past several years at 70 to 90 accidents per year.
What happens to deer that are killed by automobiles? There was a time when some of them were taken to Coventry Farm, where a lady used them to feed the vultures. She developed quite a following in the vulture community over time. These days, a contractor carts them away and turns them into fertilizer.
