In California, $120,000 was spent over two years to provide birth control for approximately a dozen deer that inhabit Coyote Hills Park. The effort was unsuccessful; the deer population continues to grow while the available edible foliage does not, leading to starvation among the animals. Park rangers are considering a more traditional, if less sensitive, method of population control—shooting the excess deer and giving the venison to locals in need of the meat.
