While fire is part of many natural ecosystems, wildland fires -- caused by nature or humans -- can burn out of control and destroy forests, brush, field crops, grasslands, and property.
The wildland fire season in Washington usually begins in early July and typically culminates in late September. However, wildland fires have occurred in every month of the year. Drought, snow pack, and local weather conditions can expand the length of the fire season. The early and late shoulders of the fire season usually are associated with human-caused fires. Lightning generally is the cause of most fires in the peak fire period of July, August and early September.
