While the North American chaparral is most famous, the chaparral biome can be found all over the world. Due to the lower annual rainfall (resulting in slower plant growth rates) when compared to cismontane chaparral, desert chaparral is more vulnerable to biodiversity loss and the invasion of non-native weeds and grasses if disturbed by human activity and frequent fire. The chaparral biome is hot, dry, and prone to fires. The type of vegetation found in the chaparral is scrubs and short bushes. Role of high fire frequency in destruction of mixed chaparral.  It is distinguished from the cismontane chaparral found on the coastal side of the mountains, which experiences higher winter rainfall. The chaparral is found in California. It is found in dry climates with a drainage soil like of course the chaparral of California, Australia, and south Africa. This is mainly a factor of humans changing other biomes to custom fit the world to their needs. Chaparral is a type of woodland characterized by a combination of dry soil, warm weather, and short, hardy shrubs. Another phytogeography system uses two California chaparral and woodlands subdivisions: the cismontane chaparral and the transmontane (desert) chaparral. • Similar plant communities can be found in other Mediterranean climates such as the Maquis in the Mediterranean basin, the matorral in Chile, and the fynbos in South Africa as well as western and southern Australia.  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. International Journal of Wildland Fire 14: 255–265. Human influence on California fire regimes. Madrono 42: 175–179. The chaparral area receives about 38–100 cm (15–39 in) of precipitation a year. 232 p. Hanes, T. L. 1971. Second Edition. There are two assumptions relating to California chaparral fire regimes that have caused considerable debate, and sometimes confusion and controversy, within the fields of wildfire ecology and land management. If the intervals between fires increase to around once every 15 years, many species of flora will die. Keeley.  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. Chaparral or Mediterranean forests, woodlands, and shrub is a temperate biome, characterized by hot-dry summers and mild and rainy winters. Science 219:1287–1294. 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). Chaparral Biome, Merced County, California, USA. Keeley, J. E., C. J. Fotheringham, and M. Morais. Stafford. The following is a short list of birds which are an integral part of the cismontane chaparral ecosystems. In addition, because trees and shrubs lose a lot of water through their leaves through transpiration, plants in the Chaparral have developed thick, waxy leaves to avoid dehydration. These plants have evolved smaller, firmer leaves, with a waxy surface that conserves moisture. Vale, T. R. 2002. Summers are very dry and all the plants - trees, shrubs, and grasses - are more or less dormant then. Island Press, Washington, DC, USA. a. Grasslands have rich soil that supports abundant plant life. I have taken notes on the different trophic levels within the California Chaparral. Some chaparral species are adapted to nutrient-poor soils developed over serpentine and other ultramafic rock, with a high ratio of magnesium and iron to calcium and potassium, that are also generally low in essential nutrients such as nitrogen. A chaparral is a type of biome, an earth environment where we find living things. There are a couple of different types of plants that are able to do very well in a chaparral biome. 1995.  However, according to recent studies, California chaparral is extraordinarily resilient to very long periods without fire and continues to maintain productive growth throughout pre-fire conditions. 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. This biome is a perfect example of a dry part of the Earth. International Association of Wildland Fire, Fairfield, Wash. Transmontane chaparral features xeric desert climate, not Mediterranean climate habitats, and is also referred to as desert chaparral. This biome has mild winters with abundant rainfall, and extremely dry summers. The trees that grow in the chaparral often have small wax coated leaves to prevent evaporation of water or needle shaped leaves to pull water from the air.
