In a wilderness area at the northwest corner of Joshua Tree National Park, ecologist Lynn Sweet treks across the high desert as raucous pinyon jays swoop overhead. She navigates carefully across the landscape of blackbrush and fragrant junipers to inspect the stump of a Joshua tree. Much of the tree’s trunk, branches, and dagger-shaped leaves are sprawled across the desert floor—most likely the casualty of a gust of wind that snapped it like a toothpick.

This past May, outside the Joshua Tree National Park just south of the Twentynine Palms Highway, a 150-acre fire ignited on conservation land owned by Mojave Desert Land Trust when a man flicked a lit cigarette butt into dry brush while hiking.
