Effort To Save Sequoias In Yosemite

The giant Rim Fire raging near Yosemite National Park is threatening two groves of giant sequoias: the Tuolumne Grove and the Merced Grove.

The redwoods have some natural defenses against wildfires, but firefighters are clearing brush near the groves and setting up sprinkler systems to provide the ancient trees with extra help if the fire does spread to the groves.
