Armed with appetites and attitudes, brush-clearing goats can mow down weeds and shrubs from even the steepest of Southern California’s hillsides.

We join Ian Newsam, owner of Brush Goats 4 Hire, and his “elite” herd of goats as they reduce the invasive plants and fuel that contribute to the fires.
