Introduction[edit] In its natural state, chaparral is characterized by infrequent fires, with intervals ranging between 10–15 years and over a hundred years. Mature chaparral (stands that have survived for greater intervals between fires) is characterized by nearly impenetrable, dense thickets (except the more open chaparral of the desert). These plants are highly flammable during the late summer and autumn months when conditions are characteristically hot and dry. They grow as woody shrubs with thick, leathery, and often small leaves, contain green leaves all year (are evergreen), and are typically drought resistant (with some exceptions[2]). After the first rains following a fire, the landscape is dominated by small flowering herbaceous plants, known as fire followers, which die back with the summer dry period. Similar plant communities are found in the four other Mediterranean climate regions around the world, including the Mediterranean Basin (where it is known as maquis), central Chile (where it is called matorral), the South African Cape Region (known there as fynbos), and in Western and Southern Australia (as kwongan). According to the California Academy of Sciences, Mediterranean shrubland contains more than 20 percent of the world's plant diversity.[1] The word chaparral is a loan word from Spanish chaparro, meaning both "small" and "dwarf" evergreen oak, which itself comes from a Basque word, txapar, that has the same meaning. Conservation International and other conservation organizations consider chaparral to be a biodiversity hotspot[3] – a biological community with a large number of different species – that is under threat by human activity.

California chaparral[edit] California chaparral and woodlands ecoregion[edit] Main article: California chaparral and woodlands Southern coastal scrub in the Santa Monica Mountains National Recreation Area The California chaparral and woodlands ecoregion, of the Mediterranean forests, woodlands, and scrub biome, has three sub-ecoregions with ecosystem—plant community subdivisions: California coastal sage and chaparral: In coastal Southern California and northwestern coastal Baja California, as well as all of the Channel Islands off California and Guadalupe Island (Mexico). California montane chaparral and woodlands: In southern and central coast adjacent and inland California regions, including covering some of the mountains of the California Coast Ranges, the Transverse Ranges, and the western slopes of the northern Peninsular Ranges. California interior chaparral and woodlands: In central interior California surrounding the Central Valley, covering the foothills and lower slopes of the northeastern Transverse Ranges and the western Sierra Nevada range. Chaparral and woodlands biota[edit] For the numerous individual plant and animal species found within the California chaparral and woodlands ecoregion, see: Flora of the California chaparral and woodlands Fauna of the California chaparral and woodlands. Some of the indicator plants of the California chaparral and woodlands ecoregion include: Quercus species – oaks: Quercus agrifolia – coast live oak Quercus berberidifolia – scrub oak Quercus chrysolepis – canyon live oak Quercus douglasii – blue oak Quercus wislizeni – interior live oak Artemisia species – sagebrush: Artemisia californica – California sagebrush, coastal sage brush Arctostaphylos species – manzanitas: Arctostaphylos glauca – bigberry manzanita Arctostaphylos manzanita – common manzanita Ceanothus species – California lilacs: Ceanothus cuneatus – buckbrush Ceanothus megacarpus – bigpod ceanothus Rhus species – sumacs: Rhus integrifolia – lemonade berry Rhus ovata – sugar bush Eriogonum species – buckwheats: Eriogonum fasciculatum – California buckwheat Salvia species – sages: Salvia mellifera – black sage Chaparral soils and nutrient composition Soils in the California chaparral are made of serpentine rock and are generally low in essential nutrients such as nitrogen. Another characteristic of these soils is that they are ultramafic, meaning they have a high ratio of magnesium and iron to calcium and potassium. California cismontane and transmontane chaparral subdivisions[edit] Another phytogeography system uses two California chaparral and woodlands subdivisions: the cismontane chaparral and the transmontane (desert) chaparral. California cismontane chaparral[edit] Cismontane chaparral ("this side of the mountain") refers to the chaparral ecosystem in the Mediterranean forests, woodlands, and scrub biome in California, growing on the western (and coastal) sides of large mountain range systems, such as the western slopes of the Sierra Nevada in the San Joaquin Valley foothills, western slopes of the Peninsular Ranges and California Coast Ranges, and south-southwest slopes of the Transverse Ranges in the Central Coast and Southern California regions. Cismontane chaparral plant species[edit] For more flora species, see Category: Natural history of the California chaparral and woodlands. In Central and Southern California chaparral forms a dominant habitat. Members of the chaparral biota native to California, all of which tend to regrow quickly after fires, include: Adenostoma fasciculatum, chamise Adenostoma sparsifolium, redshanks Arctostaphylos spp., manzanita Ceanothus spp., ceanothus Cercocarpus spp., mountain mahogany Cneoridium dumosum, bush rue Eriogonum fasciculatum, California buckwheat Garrya spp., silk-tassel bush Hesperoyucca whipplei, yucca Heteromeles arbutifolia, toyon Acmispon glaber, deerweed Malosma laurina, laurel sumac Marah macrocarpus, wild cucumber Mimulus aurantiacus, bush monkeyflower Pickeringia montana, chaparral pea Prunus ilicifolia, islay or hollyleaf cherry Quercus berberidifolia, scrub oak Q. dumosa, scrub oak Q. wislizenii var. frutescens Rhamnus californica, California coffeeberry Rhus integrifolia, lemonade berry Rhus ovata, sugar bush Salvia apiana, white sage Salvia mellifera, black sage Xylococcus bicolor, mission manzanita Cismontane chaparral bird species[edit] For more bird species, see Category: Fauna of the California chaparral and woodlands. The complex ecology of chaparral habitats supports a very large number of animal species. The following is a short list of birds which are an integral part of the cismontane chaparral ecosystems. Species essential to the health of the ecosystem include: California thrasher (Toxostoma redivivum) California towhee (Pipilo crissalis) Spotted towhee (Pipilo maculatus) Western scrub jay (Aphelocoma californica) Very common inhabitant species include: Anna's hummingbird (Calypte anna) Bushtit (Psaltriparus minimus) Costa's hummingbird (Calypte costae) Greater roadrunner (Geococcyx californianus) Wrentit (Chamaea fasciata) California transmontane (desert) chaparral[edit] Transmontane chaparral or desert chaparral —transmontane ("the other side of the mountain") chaparral—refers to the desert shrubland habitat and chaparral plant community growing in the rainshadow of these ranges. Transmontane chaparral features xeric desert climate, not Mediterranean climate habitats, and is also referred to as desert chaparral.[4][5] Desert chaparral is a regional ecosystem subset of the deserts and xeric shrublands biome, with some plant species from the California chaparral and woodlands ecoregion. Unlike cismontane chaparral, which forms dense, impenetrable stands of plants, desert chaparral is open, with only about 50 percent of the ground covered.[6] Individual shrubs can reach up to 10 feet (3.0 m) in height. View from the Laguna Mountains, chaparral in the foreground Transmontane chaparral or desert chaparral is found on the eastern slopes of major mountain range systems on the western sides of the deserts of California. The mountain systems include the southeastern Transverse Ranges (the San Bernardino and San Gabriel Mountains) in the Mojave Desert north and northeast of the Los Angeles basin and Inland Empire; and the northern Peninsular Ranges (San Jacinto, Santa Rosa, and Laguna Mountains), which separate the Colorado Desert (western Sonoran Desert) from lower coastal Southern California.[6] It is distinguished from the cismontane chaparral found on the coastal side of the mountains, which experiences higher winter rainfall. Naturally, desert chaparral experiences less winter rainfall than cismontane chaparral. Plants in this community are characterized by small, hard (sclerophyllic) evergreen (non-deciduous) leaves. Desert chaparral grows above California's desert cactus scrub plant community and below the pinyon-juniper woodland. It is further distinguished from the deciduous sub-alpine scrub above the pinyon-juniper woodlands on the same side of the Peninsular ranges. Transmontane chaparral distribution[edit] Transmontane (desert) chaparral typically grows on the lower (3,500–4,500 feet (1,100–1,400 m) elevation) northern slopes of the southern Transverse Ranges (running east to west in San Bernardino and Los Angeles counties) and on the lower (2,500–3,500 feet (760–1,070 m)) eastern slopes of the Peninsular Ranges (running south to north from lower Baja California to Riverside and Orange counties and the Transverse Ranges).[7] It can also be found in higher-elevation sky islands in the interior of the deserts, such as in the upper New York Mountains within the Mojave National Preserve in the Mojave Desert.[citation needed] The California transmontane (desert) chaparral is found in the rain shadow deserts of the following: Sierra Nevada creating the Great Basin Desert and northern Mojave Desert Transverse ranges creating the western through eastern Mojave Desert Peninsular ranges creating the Colorado Desert and Yuha Desert.[4][5] Transmontane chaparral plants[edit] Adenostoma fasciculatum, chamise (a low shrub common to most chaparral with clusters of tiny needle like leaves or fascicles; similar in appearance to coastal Eriogonum fasciculatum) Agave deserti, desert agave Arctostaphylos glauca, bigberry manzanita (smooth red bark with large edible berries; glauca means blue-green, the color of its leaves) Ceanothus greggii, desert ceanothus, California lilac (a nitrogen fixer, has hair on both sides of leaves for heat dissipation) Cercocarpus ledifolius, curl leaf mountain mahogany, a nitrogen fixer important food source for desert bighorn sheep Dendromecon rigida, bush poppy (a fire follower with four petaled yellow flowers) Ephedra spp., Mormon teas Fremontodendron californicum, California flannel bush (lobed leaves with fine coating of hair, covered with yellow blossoms in spring) Opuntia acanthocarpa, buckhorn cholla (branches resemble antlers of a deer) Opuntia echinocarpa, silver or golden cholla (depending on color of the spines) Opuntia phaeacantha, desert prickly pear (fruit is important food source for animals) Purshia tridentata, buckbrush, antelope bitterbrush (Rosaceae family) Prunus fremontii, desert apricot Prunus fasciculata, desert almond (commonly infested with tent caterpillars of Malacosoma spp.) Prunus ilicifolia, holly leaved cherry Quercus cornelius-mulleri, desert scrub oak or Muller's oak Rhus ovata, sugar bush Simmondsia chinensis, jojoba Yucca schidigera, Mojave yucca Hesperoyucca whipplei (syn. Yucca whipplei), foothill yucca – our lord's candle. Transmontane chaparral animals[edit] There is overlap of animals with those of the adjacent desert and pinyon-juniper communities.[8] Canis latrans, coyote Lynx rufus, bobcat Neotoma sp., desert pack rat Odocoileus hemionus, mule deer Peromyscus truei, pinyon mouse Puma concolor, mountain lion Stagmomantis californica, California mantis

Wildfires[edit] This section needs additional citations for verification. Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. (December 2013) (Learn how and when to remove this template message) Chaparral is a coastal biome with hot, dry summers and mild, rainy winters. The Chaparral area receives about 38–100 cm (15–39 in) of precipitation a year. This makes the chaparral most vulnerable to fire in the late summer and fall. The chaparral ecosystem as a whole is adapted to be able to recover from infrequent wildfires (fires occurring a minimum of 15 years apart); indeed, chaparral regions are known culturally and historically for their impressive fires. (This does create a conflict with human development adjacent to and expanding into chaparral systems.) Additionally, Native Americans burned chaparral to promote grasslands for textiles and food.[9] Before a major fire, typical chaparral plant communities are dominated by manzanita, chamise (also called greasewood; Adenostoma fasciculatum) and Ceanothus species, toyon (which can sometimes be interspersed with scrub oaks), and other drought-resistant shrubs with hard (sclerophyllous) leaves; these plants resprout (see resprouter) from underground burls after a fire.[citation needed] The shoots of these plants are, however, not resistant to chaparral crown-fire regimes as the bark is simply not thick enough. Plants that are long-lived in the seed bank or serotenous with induced germination after fire include chamise, Ceanothus, and fiddleneck. Some chaparral plant communities may grow so dense and tall that it becomes difficult for large animals and humans to penetrate, but may be teeming with smaller fauna in the understory. Many chaparral plant species require some fire cue (heat, smoke, or charred wood, and chemical changes in the soil following fires) for germination. Others, such as annual and herbaceous species like Phacelia require fires to allow sunlight to reach them, and are known as fire followers.[citation needed] During the time shortly after a fire, chaparral communities may contain soft-leaved herbaceuous annual plants that dominate the community for the first few years – until the burl resprouts and seedlings of chaparral perennials create an overstory, blocking the sunlight from other plants in the community. When the overstory regrows, seeds of annuals and smaller plants may lie dormant until the next fire creates the conditions required for germination. Mid-sized plants such as Ceonothus fix nitrogen, while others cannot, which, together with the need for exposure to the sun, creates a symbiotic relationship of the entire community with infrequent fires.[citation needed] Because of the hot, dry conditions that exist in the California summer and fall, chaparral is one of the most fire-prone plant communities in North America. Some fires are caused by lightning, but these are usually during periods of high humidity and low winds and are easily controlled. Nearly all of the very large wildfires are caused by human activity during periods of very hot, dry easterly Santa Ana winds. These man-made fires are commonly caused by power line failures, vehicle fires and collisions, sparks from machinery, arson, or campfires. In natural Chaparral communities without human interference, the fires are ignition-prone as there are plenty of ground fuels and the temperatures are fire-permitting during the dry season. Though adapted to infrequent fires, chaparral plant communities can be exterminated by frequent fires. A moderate frequency of fire (less than ten years) will result in the loss of seeder plants such as Manzanita spp. This moderate frequency disallows seeder plants to reach their reproductive size before the next fire and the community shifts to a sprouter-dominance. High frequency fires (less than five years) can cause the additional loss of sprouters by exhausting their reserves below-ground. Today, frequent accidental ignitions can convert chaparral from a native shrubland to non-native annual grassland and drastically reduce species diversity, especially under drought brought about by climate change.[10][11] Wildfire debate[edit] There are two assumptions relating to California chaparral fire regimes that appear to have caused considerable debate, and sometimes confusion and controversy, within the fields of wildfire ecology and land management. That older stands of chaparral become "senescent" or "decadent", thus implying that fire is necessary for the plants to remain healthy,[12] That wildfire suppression policies have allowed dead chaparral to accumulate unnaturally, creating ample fuel for large fires.[13] The perspective that older chaparral is unhealthy or unproductive may have originated during the 1940s when studies were conducted measuring the amount of forage available to deer populations in chaparral stands.[citation needed] However, according to recent studies, California chaparral is extraordinarily resilient to very long periods without fire[14] and continues to maintain productive growth throughout pre-fire conditions.[15][16] Seeds of many chaparral plants actually require 30 years or more worth of accumulated leaf litter before they will successfully germinate (e.g., scrub oak, Quercus berberidifolia; toyon, Heteromeles arbutifolia; and holly-leafed cherry, Prunus ilicifolia). When intervals between fires drop below 10 to 15 years, many chaparral species are eliminated and the system is typically replaced by non-native, invasive, weedy grassland.[17][18][19] The idea that older chaparral is responsible for causing large fires was originally proposed in the 1980s by comparing wildfires in Baja California and southern California .[citation needed] It was suggested that fire suppression activities in southern California allowed more fuel to accumulate, which in turn led to larger fires[citation needed] (in Baja, fires often burn without active suppression efforts[citation needed]). This is similar to the argument that fire suppression in western United States has allowed ponderosa pine forests to become “overstocked”.[citation needed] In the past, surface fires burned through these forests at intervals of anywhere between 4 and 36 years, clearing out the understory and creating a more ecologically balanced system.[citation needed] However, chaparral has a crown-fire regime, meaning that fires consume the entire system whenever they burn, with a historical frequency of 30 to 50 years.[citation needed] In one study, a detailed analysis of historical fire data concluded that fire suppression activities have been ineffective at excluding fire from southern California chaparral, unlike in ponderosa pine forests.[14] In addition, the number of fires is increasing in step with population growth. Chaparral stand age does not have a significant correlation to its tendency to burn.[20] Low humidity, low fuel moisture, and high winds appear to be the primary factors in determining when and where a chaparral fire occurs and how large it becomes.[citation needed] Fires can be beneficial to plant communities by clearing away canopies of litter, inducing serotenous germination, and sanitizing the soils from pathogens.
