Chaparral is an evergreen shrubland or woodland vegetation type that occurs in areas characterized by hot, dry summer conditions, classified as a Mediterranean climate. Chaparral shrublands and woodlands are found on over three million ha (eight million ac) in California and in several locations in Oregon, Washington, and Arizona. Similar vegetation is found in Baja California (Mexico), the Mediterranean Basin, Central Chile, southwestern Australia, and southeastern South Africa. High-intensity wildfires that generally occur during the dry, hot season are associated with chaparral shrublands.


Chaparral occurs in areas with a Mediterranean-type climate that is characterized by mild, moist winters and hot, dry summers. Temperatures range from −3 ° to 18  C (26.6° to 64.4 °F) in the coolest month, precipitation pattern of <40 mm (1.6 in) of rain during summer, and summer temperatures above 22 °C...
