The 2009 California wildfires were a series of 63 wildfires that were active in the state of California, USA, during the year 2009.[1] The fires burned more than 336,020 acres (525 sq mi; 1,360 km2) of land from the beginning of July through late November due to red flag warnings, destroying hundreds of structures and killing two people.[2] Although the fires burned many different regions of California in August, the month was especially notable for several very large fires which burned in Southern California, despite being outside of the normal fire season for that region.
The Station Fire, north of Los Angeles, was the largest and deadliest of these wildfires, burning 160,577 acres (251 sq mi; 650 km2) and killing two firefighters since it began in late August. Another large fire was the La Brea Fire, which burned nearly 90,000 acres (141 sq mi; 364 km2) in Santa Barbara County earlier in the month. A state of emergency was also declared for the 7,800 acres (12 sq mi; 32 km2) Lockheed Fire in Santa Cruz County to the north.

Invasive, non-native vegetation dies and re-sprouts year after year creating an unnatural buildup of dead plant material.[3] While periodic fires are natural, and many native plants depend upon fire to reproduce,[4] the intensity and frequency of these fires is altered by the presence of non-natives.[3]
In Southern California, the normal wildfire season begins in October with the arrival of the infamous Santa Ana winds, and it is unusual to see fires spread so rapidly at other times of year. However, temperatures throughout the southern part of the state exceeded 100 °F (38 °C) for much of late August. The combination of high temperatures, low humidity and a large quantity of tinder-dry fuel, some of which had not burnt for decades, allowed some of the normal fires to quickly explode out of control despite the lack of winds to spread the flames. These conditions, along with extreme terrain in many undeveloped areas that slowed access to burn areas, made firefighting difficult.
Dozens of fires burned throughout California in August 2009. Some of the most notable are listed here.
August fires also struck areas of Colusa, Lassen, Plumas, Santa Clara, Shasta, Siskiyou and Solano counties.

The Guiberson fire in Ventura County has burnt an estimated 8,500 acres (34 km2), destroying two outbuildings and injuring two firefighters. Governor Schwarzenegger declared a state of emergency. The fire, which started between Fillmore and Moorpark, has caused the evacuation of almost 600 homes in Meridian Hills and Bardsdale; about 1,000 structures are threatened, in addition to oil pipelines in the area. On September 27, the Guiberson Fire was 100 percent contained after burning approximately 17,500 acres (71 km2); the cause is still unconfirmed.[53]
Smaller fires also broke out in Orange, Riverside, San Bernardino and San Diego counties in August.
