A biome characterized by hot dry summers and cool moist winters and dominated by a dense growth of mostly small-leaved evergreen shrubs, as that found in the foothills of California. It occurs usually in regions having from 10 to 20 in. (25-50 cm) of rainfall annually and with a Mediterranean-type climate. Where the rate of evaporation is high, chaparral may be found where the rainfall is well above 20 in. Generally chaparral country has most of its rainfall in the winter. The vegetation includes both evergreen and deciduous forms, the dominant species varying in different areas. Chaparral is well exemplified in parts of the Western and Southwstern United States.
