The Department of Forestry and Fire Protection (CalFire) is responsible for wildland fire protection in State Responsibility Areas (SRAs), which are primarily privately owned wildlands that encompass about one-third of the state.
CalFire employs around 4,000 permanent and 2,500 seasonal firefighters, operates an aviation program (aircraft, helicopters, and air tankers), and runs about 250 fire stations and air attack bases.
