As you can see Southern California contains many different life zones based upon a wide range of climates and vegetation. Life zones is an older system of classification originally based upon temperature. It has gradually been replaced by a system of classification based upon biomes. In Southern California the dominant form of vegetation is chaparral. Chaparral belongs to a biome called the scrub biome. Other California biomes are the grassland, desert, coniferous forest, temperate rain forest, tundra and temperate deciduous forest. The chaparral is located primarily in the Upper and Lower Sonoran. The area we will explore today is located in the transverse mountains of the Southern regions of California.
