The California coastal sage and chaparral (Spanish: Salvia y chaparral costero de California) is a Mediterranean forests, woodlands, and scrub ecoregion, defined by the World Wildlife Fund, located in southwestern California (United States) and northwestern Baja California . It is part of the larger California chaparral and woodlands ecoregion.
One common factor among chaparral, however, is that a minimum of 10 years is needed between fires for the chaparral to mature and set enough seed in the soil to create a fire resilient environment. As human activity increases the frequency of fires, the chaparral's ability to renew itself decreases, leading to elimination and degradation.
[6] [7] 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 often open, with only about 50 percent of the ground covered. [8]

Though adapted to infrequent fires, chaparral plant communities can be exterminated by frequent fires especially with climate change induced drought. [ 4 ] [ 5 ] Today, frequent accidental ignitions can convert chaparral from a native shrubland to nonnative annual grassland and drastically reduce species diversity, especially under global ...

Approximately 30 percent of California montane chaparral and woodlands remains intact. About 70 percent has been lost due to degradation activities of humans. [4] Montane chaparral is threatened chiefly by development, grazing, logging, conversion to vineyards, and too-frequent wildfire. [5]
The western and eastern Sierra Nevada have substantially different species of plants and animals, because the east lies in the rain shadow of the crest. The plants and animals in the east are thus adapted to much drier conditions. [4] The altitudes listed for the biotic zones are for the central Sierra Nevada.
