Chaparral is the smallest biome. It is found in specific areas between places with a hot, dry climate and high atmospheric pressure, and those with cool, wet climates and low atmospheric pressure (Ricciuti, 9). It shares certain characteristics with its neighboring biomes. Chaparral grows between forest and grassland, or between desert and grassland biomes.

The chaparral is home to many drought and fire resistant plants. Many of these plants and trees have leathery leaves, gnarled bark, and intimidating thorns.
