Transcript of Chaparral Biome.

Chaparral Biome
Longitude & Latitude
Average Rainfall:
10 - 17 inches per year. There is very little rain.
Abiotic Factors
Soil Composition:
The soil is not very nutrient rich and is fairly dry. The soil erodes easily and the as it is generally shallow with clay or rock underneath.
More Abiotic Factors
Average Temperature:

ranges from 30 - 100 degrees Fahrenheit with and average of 64 degrees. The chaparral has mild seasons due to the ocean.
Wind Patterns:
generally cool, dry ocean breezes.
Geographic Features:
hills and mountains with slopes of 20-70 degrees.
Solar Radiation:
large amounts of sunlight and heat (drought area)
Limiting Factors:
The water amount and availability is relatively low. Plants can only absorb so much water. Also the nutrient amounts in the soil limits growth.
Some examples of Chaparral regions are the Mediterranean Sea border, central Chile, and southern California to northern Baja California.

The Spanish Broom is an invasive species. This species was along mountain highways in southern California. It spread rapidly producing seeds that were transported by erosion or rain wash. This species quickly colonizes and creates thick shubs and prevents colonization by native soft or hard chaparral species. Its grows tall and creates a large amount of dead wood.When this plant gets dry it becomes a fire hazard.

General Environmental Status
The "soft" chaparral, also known as coastal sage scrub is threatened by

due to urban and suburban expansion. This is particularly true here in California.
Chaparral is particularly susceptible to intense
, the potential for such fires increases with human over development.
Efforts have been made to preserve the chaparral biome in California. Several Examples of preserved chaparral are the Cleveland, Angeles, San Bernardino, and the Los Padres National Forests

This is a Black-tailed jackrabbit.
It lives in the extreme parts of the biome. It likes hot days, cold night and little to no rain.

The California condor is rapidly going extinct. In 2000 only 22 condors were left and we took extreme measures like collecting eggs and taking care of the condor. This bird is going extinct for many reasons including: shooting, lead poisoning, they encounter power lines, and habitat loss. There are about only 130 condors left and this is not enough to say they will not go extinct. A good thing about this bird is that they prey on carcases and this is a big help to environment because it prevents waste build up.
A keystone species in the chaparral biome is the kangaroo rat. It is important because it has a huge effect on other species in this biome. They present strong competition with the other species in this biome.
