More than a thousand goats have been put to work in the Cleveland National Forest near San Diego. They're there to remove dried brush and plants that act as fire hazards.

Officials say so far, using the goats to eat the brush has cost just one-third of what it costs to have people remove the plants.

Researchers will monitors parts of the park to see how well the area stays cleared.
