The Leeward Hills ecoregion includes mountains and hills with rounded ridges, steep and moderately steep sides, and narrow canyons. It occurs inland from the wetter Santa Cruz Mountains ecoregion (1n). Elevations range from about 200 feet to peaks greater than 3,700 feet. Metasedimentary and metavolcanics of the Franciscan Complex occur along with other Cretaceous sedimentary rocks, and minor areas of ultramafics and Plio-Pleistocene non-marine sediments. Soil temperature regimes are thermic and soil moisture regimes are xeric. Common vegetation includes annual grassland, coast live oak, California bay, and a few areas of chaparral.
