Chaparral is a shrubland or heathland plant community found primarily in the U.S. state of California and in the northern portion of the Baja California peninsula, Mexico. It is shaped by a Mediterranean climate (mild, wet winters and hot dry summers) and wildfire, featuring summer drought-tolerant plants with hard sclerophyllous evergreen leaves, as contrasted with the associated soft-leaved, drought deciduous, scrub community of Coastal sage scrub, found below the chaparral biome. Chaparral covers 5% of the state of California, and associated Mediterranean scrubland an additional 3.5%.
