Chaparral Biome: Definition & Locations
Lesson Transcript
Instructor: Derrick Arrington
Derrick has taught biology and chemistry at both the high school and college level. He has a master's
degree in science education.
Our world is composed of numerous biomes. In this lesson, we will take a closer look at the
chaparral biome to gain an understanding of what makes up this dynamic and unique part of our
planet.
Definition of a Chaparral Biome
A biome is a naturally occurring community of plants and wildlife that occupy a particular habitat.
Chaparral biomes are composed of a variety of different types of terrain including plains, rocky
hills, and mountain slopes.
The climate of the chaparral biome can be characterized as hot and dry in the summer, with
temperatures steadily reaching 105 degrees Fahrenheit, and mild in the winter, with temperatures
remaining at around 50 degrees Fahrenheit. These conditions make the chaparral very susceptible to
droughts and wildfires as the biome normally receives only 10-15 inches of rain per year.
Locations of Chaparral Biomes
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.
In the United States, the chaparral biome can be found in the Santa Barbara area of California. The
Los Padres National Forest and Channel Islands National Parks are areas found near Santa Barbara
that have been set aside to preserve the Chaparral biomes and to allow the public to explore them.
The rocky coastal areas of Chile in South America are considered to be a chaparral biome. They are
inhabited by Chilean deer as well as other small mammals who have adapted to live in the dry hot
climate composed mostly of scrub bushes.
A great portion of southern South Africa is chaparral biome. It is home to many unique plants found
nowhere else in the world - such as the Protea plant - that have adapted to live in the dry, arid climate
that is frequented by wildfires.
If you close your eyes and envision the wild Australian outback, you may see a rocky semimountainous region dotted with small bushes and several species of grasses. This is a classic
example of a chaparral biome. One unique inhabitant of the chaparral biome in Australia is the great
gray kangaroo. It has evolved to successfully live by feeding on the small shrubs and grasses that
grow there.
Coastal areas along the Mediterranean are also considered chaparral biomes. These arid areas are
mostly composed of rocky mountainsides that are sparsely populated with shrubs and grasses as well
as small mammals that are suited to live in the area. In this part of the world the biome is often
referred to as the Mediterranean scrub.
Plants and Animals in the Chaparral
The plants found in the chaparral biome have evolved special characteristics to survive in the
conditions found there. These characteristics include small hard leaves which hold moisture.
Common examples of the plants found in the chaparral biome include scrub oak, poison oak, and
cacti. The animals are those adapted to hot, dry weather and include coyotes, jackrabbits, mule deer,
and horned toads.
