Characteristics;Plant community Coastal sage scrub is characterized by low-growing aromatic, and drought-deciduous shrubs adapted to the semi-arid of the coastal lowlands. The community is sometimes called "soft " due to the predominance of soft, drought-deciduous leaves in contrast to the hard, waxy-cuticled leaves on sclerophyllous plants of California's chaparral communities. ;Flora Characteristic shrubs and subshrubs include: * California sagebrush (''Artemisia californica'') * (''Salvia mellifera'') * (''Salvia apiana'') * Eriogonum fasciculatum, California buckwheat (''Eriogonum fasciculatum'') * Encelia californica, Coast brittle-bush (''Encelia californica'') * Eriophyllum confertiflorum, Golden yarrow (''Eriophyllum confertifolium'') Larger shrubs include: * Toyon (''Heteromeles arbutifolia'') * Rhus integrifolia, Lemonade berry (''Rhus integrifolia'') Herbaceous plant, Herbaceous plants, Poaceae, grasses, and in some locales, cactus, cacti and succulents, are also part of the flora. Hesperoyucca whipplei, colloquially known as Chaparral Yucca, is commonplace throughout the climate zone.
Geographical subtypesThe coastal sage scrub plant community is divided into three geographical subtypes — northern coastal scrub, southern coastal scrub, and maritime succulent scrub. The coastal scrub communities are divided into three regions: # Northern coastal scrub, Northern Coastal Scrub and California coastal prairie, Coastal Prairie, which lies in San Luis Obispo County, California, San Luis Obispo to Oregon. # Coastal Sage scrub, which lies in San Diego County, California, San Diego to Monterey County, California, Monterey. # Maritime Succulent Scrub, which can be found in the San Diego County to Baja California Peninsula, Baja California. # The Northern Coastal Scrub consists of prairie, which is terraces with deep alluvial soils, and scrub, which is found on steeper slopes and ravine areas. Evergreen shrubs and subshrubs, which are soft leaves. They are found in semi-open with a height of 2–3 meters, with multiple layers. Some examples of the plant species that can be found are Bush monkeyflower (''Mimulus aurantiacus''), Poison oak (Toxicodendron diversilobum, ''Taxicodendron'' ''diversilobum''), Coffee berry (Frangula californica, ''Frangula'' ''californica''), Golden yarrow (Eriophyllum confertiflorum, ''Eriophyllum'' ''confertiflorum''). California sagebrush (''Artemisia californica'') can be found in Coastal Sage Scrub community, especially in Orange County, California, Orange County. Some other plant species that can be found is also Giant coreopsis (''Coreopsis gigantea''), Black sage (''Salvia mellifera''), California buckwheat (''Eriogonum fasciculatum, Eriogonoum fasciculatum)'', and White sage (''Salvia apiana''). Plant species that can be found in Maritime Succulent Scrub is Coast prickly pear (''Opuntia littoralis''), Coast barrel cactus (''Ferocactus viridescens''), Cliff spurge (''Euphorbia misera''), Bush rue (''Cneoridium dumosum''), and Dudleya spp.
Northern coastal scrubNorthern coastal scrub occurs along the Pacific Coast from the northern San Francisco Bay Area to southern Oregon. It frequently forms a landscape mosaic with the California coastal prairie plant community. The predominant plants are low evergreen shrubs and herbs. Characteristic shrubs include coyote brush (''Baccharis pilularis''), Eriodictyon californicum, yerba santa (''Eriodictyon californicum''), coast silk-tassel (''Garrya elliptica''), salal (''Gaultheria shallon''), and yellow bush lupine (''Lupinus arboreus''). Herbaceous species include western blue-eyed grass (''Sisyrinchium bellum''), Douglas iris (''Iris douglasiana''), and Poaceae, grasses.
Southern coastal scrubSouthern coastal scrub is mostly found along the maritime Central Coast of California, Central Coast region, and the terraces and mountains with coastal climate influence in Southern California. Its distribution extends from the southwestern San Francisco Bay Area in the north, through Big Sur, Vandenberg Air Force Base, the Oxnard Plain, the Los Angeles Basin, most of Orange County, California, Orange County, parts of Riverside County, coastal San Diego County, and the northwestern region of Baja California state in Mexico, including the areas around Tijuana and Ensenada, Baja California, Ensenada. ;Southern California The metropolitan areas of Los Angeles, San Diego, and Tijuana are located in the southern coastal scrublands, and most of the scrublands have been lost to urbanization and agriculture. The plants of this community prefer the mild maritime climates found along Southern California's coastline. World Wildlife Fund estimates that only 15 percent of the coastal sage scrublands remain undeveloped. Some of the remaining southern coastal scrub in Los Angeles County can be found in dunes under the takeoff path at Los Angeles International Airport, Los Angeles International Airport—LAX, in the coastal Santa Monica Mountains National Recreation Area, and at the Robert J. Bernard Field Station at the Claremont Colleges. In San Diego County, the Marine Corps Base Camp Pendleton, Camp Pendleton Marine Corps Base protects larger areas, and the Marine Corps Air Station Miramar has vernal pools and the endemic mint ''Pogogyne abramsii''. One of the largest remaining areas of inland coastal sage scrub is found in the Temescal Mountains of Riverside County. A few rare species, rare and endangered species occur in southern coastal scrub habitats. For example, the coastal California gnatcatcher (''Polioptila californica californica'') is a threatened bird species endemic (ecology), endemic to the coastal sage scrublands. Other endemic fauna includes the El Segundo blue butterfly in the LAX dunes; and the Palos Verdes blue, Palos Verdes blue butterfly (''Glaucopsyche lygdamus palosverdesensis''), at only one site on the Palos Verdes, Palos Verdes Peninsula. The endangered Torrey pine (''Pinus torreyana'') is the dominant tree at Torrey Pines State Reserve in San Diego, one of only two known stands of this pine species.
