What is the climate of the Chaparral?
The summers of the chaparral are hot and dry with the temperature ranging from 60ºF to 100ºF. The summers can be dry enough to create a drought. This dry period can extend for up to five months out of the year. These dry conditions make the risk of fires breaking out very high. These fires are usually the result of lightning Due to the pressure in the air, rain clouds do not often appear in the summer.
There are mild, and wet winters. In the winter it can get as low as freezing with the temperature ranging 30ºF to 40ºF. However, when it snow in the winter, the snow melts very quickly. Frost and little freezing weather occurs in the winter
The chaparral consists of all four seasons (summer, winter, fall, and spring). The rain precipitation ranges from 10 to 20 inches a year. The most rain pours in the fall at an average amount of 4.2 inches. In addition, the average annual temperature is 50 to 65 degrees Fahrenheit

What is the best time to visit the Chaparral?
During the summer an area of high atmospheric pressure forms and stops rain clouds from the Pacific Ocean from reaching the chaparral (June through early September). This causes the chaparral to have a drought and be very hot. In addition, most of the precipitation in the chaparral arrives during the late fall and early spring seasons. November through January brings some rain, but the raining season peaks in February. Precipitation then slows after February and completely stops in May. Therefore, the best time to visit would be May, as it is not raining, and has not yet hit drought like conditions of the summer months.
What are the biotic factors of the Chaparral?
Fauna
The animals in the Chaparral are all mainly grassland and desert types adapted to hot, dry weather; coyotes, jack rabbits, mule deer, alligator lizards, horned toads, praying mantis, honey bees and ladybugs. In California, ground birds like the quail, wrentit, and thrasher live and nest in the protection of thick, low growing shrubs of the Chaparral. Mountain lions also use the dense thickets of the chaparral to sneak up on the mule deer they eat. The bobcat, which tends to be more aggressive than the mountain lion, also finds the hiding places it needs too sneak up on its prey in the chaparral. Rattlesnakes eat large quantities of rodents like pesky rats and ground squirrels. Rattlesnakes are beneficial to the California chaparral because they keep rodent populations from getting out of control. Many chaparral animals are nocturnal. They burrow underground to escape the heat in the day and come out at night to feed. This allows them to conserve water, energy and also keeps the animal safe during fires.Some chaparral animals, like mice and lizards, secrete a semi-solid urine in order to reduce water loss.
Flora
Most chaparral plants have large, hard leaves, which hold moisture. The plants are very well adapted to fires. Plants in the chaparral often have root systems designed to get as much water as possible. Shallow roots extend horizontally under the surface of the soils and are good at catching water when it falls as rain; taproots extend deep into the soil to capture groundwater. Some of the plants in the chaparral are toyon, chemise, poison oak, scrub oak, Yucca and other shrubs, trees and cacti. Chaparral is an evergreen shrub vegetation. It forms a nearly continuous cover of closely spaced shrubs 6 to 12 feet (2 to 4 meters) tall, with intertwining branches. Herbaceous vegetation (grasses and wildflowers) is generally lacking, except after fires, which are frequent throughout the range. The most widely distributed chaparral shrub is chamise (Adenostoma fasciculatum), an adapted shrub with short needlelike leaves. Many species of Ceanothus and Arctostaphylos have woody tubers at their base that sprout new stems after fire. All species in these two categories produce deeply dormant seeds that accumulate in the soil and require fire for germination. Chaparral is commonly replaced by a smaller and highly aromatic vegetation known as soft chaparral or coastal sage. This vegetation differs from chaparral by being summer-deciduous; this loss of leaves during drought confers a greater ability to tolerate the drier conditions at low elevations. The dominant shrubs are only 3 to 6 feet tall and include California sagebrush (Artemisia californica), black sage (Salvia mellifera), California buckwheat (Eriogonum fasciculatum), deerweed (Lotus scoparius), and monkey-flower (Mimulus aurantiacus). These smaller shrubs grow rapidly and have well-developed wind dispersal of seeds so they often colonize disturbed sites. Most of the plants are less than 10 feet tall and have leathery leaves with thick cuticles that hold moisture many of the shrub flora are aromatic, contain flammable oils, and are adapted to periodic burns.

Where is the Chaparral located?
The Northern Chaparral is mustard colored (#6)
The chaparral biome is found in small sections of most continents, including the west coast of the United States, the west coast of South America, the Cape Town area of South Africa, the western tip of Australia and the coastal areas of the Mediterranean. However, the chaparral is primarily found in northern California.
What are the abiotic factors of the Chaparral?
Climate
The Californian Mediterranean climate is conducive to massive wildfires. Mild, wet winters contribute to a prolonged growing season, which, coupled with moderately fertile soils, result in dense stands of contiguous fuels.
Fire
Long summer droughts produce highly flammable fuels that are readily ignited by lightning from occasional thunderstorms but more commonly as the result of human carelessness. On average fire frequency for any one area is about every two to three decades. Throughout much of its range, chaparral forms a continuous cover over great distances, and as a result, huge wildfires that cover tens of thousands of acres are common, particularly during Santa Ana wind conditions. These dry winds from the east occur every autumn and often exceed sixty miles per hour.
Soil
The soil is very poor in nutrients, and vulnerable to erosion. The erosion of this soil can leave behind bare rock and clay. Therefore, only plants that have specially adapted to surviving in this hot, dry, and nutrient-poor soil are able to exist within this biome.
