The Chaparral Biome
The chaparral biome gets its name from the "semi-arid shrub that is dominant in these
regions. The Sclerphyllous is a woody plant that has adapted to the summer droughts and
mild, wet winters that frequent the chaparral biome". Fires occur infrequently with
natural intervals of 30 to 150 years.
This biome is found on the
western coast of the United
States and South America,
the Cape Town part of
Africa, and the western tip
of Australia as well as
coastal regions of the
Mediterranean.
Fun Fact: Did you know this
biome is most often portrayed
in "Wild West" movies?
The chaparral ranges
from flat plains, rocky
hills, to mountains.
The Chaparral Biome (cont.)
The two most common examples of the chaparral
biome are: the Mediterranean chaparral biome and
the California chaparral biome.

Biome

•
This biome is found in Europe, Africa, Asia Minor, North America,
as well as South America.
The annual rainfall is approximately 15 to 40 inches.
The temperature ranges from 37° to 91.5° F.
These particular biomes are generally located at 30° and 50° North
and South latitude, mostly on the west coasts of continents.

Vegetation of the Mediterranean
Chaparral Biome
•
The plants of this biome include: evergreens, cacti, olive trees,
flower trees (ex.oranges), and cork oak.
Some even go as far
as to have thorns to
prevent any unwanted
dinner guests from
eating them.
Did you know that
these plants have fireresistant roots?
Most of the plants here have small, leathery leaves with
a waxy covering or small hard needles and thick bark.
This is all in an effort to prevent evaporation because
the climate can get very hot and dry at times.
In order to obtain as much water as possible
through the times of droughts, plants here are
designed in a way that their roots catch and absorb
as much water as possible. Their roots don't go very
deep but rather they extend horizontally.
Aromatic Plants and Herbs
There are also aromatic plants as well as herbs which include: rosemary,
thyme, sage, and oregano.
These plants, however, are a source of danger in the sense that they have
extremely flammable oils and thus can easily play a role in forest fires. These
fires are usually caused by lightning which can release mineral nutrients that
are essential to the regeneration of a plant.
Animals of the Mediterranean
Chaparral Biome
Animals in this kind of biome have to be able to live in the
hot climate. Animals include
the Apennine wolf,
the beech-marten, deer, the black stork, the black vulture,
the dormouse, the Egyptian mongoose, the great bustard,
the hare, the hedgehog, the Iberian lynx,
the Spanish Imperial Eagle, the weasel, the wild boar,
wild goats, and wild sheep.
Animals here, just like the plants, have to be very well
adapted to the climate and terrain that is associated with
the Mediterranean Chaparral biome. Due to the rugged
terrain, animals here are excellent climbers, search for
food and provisions over a larger span of land, and adapt
their diets to fit the inadequate environment.
Done with the Mediterranean Chaparral? Guess what. It's time for you to check out the other biomes!
The California Chaparral
Biome
• This particular type of biome is mainly found on the coast of
•
•
•
California, hence the name.
The average rainfall averages from 12 to 40 inches of rain yearly.
The average temperature in the coastal areas is between 53° and
65°F and 32° and 60°F in the mountain regions.
It is located between 53° to 65° N latitude in the areas near the
coast and about 32° to 60°N latitude in the mountain areas.

Physical Features
- Just like the Mediterranean Chaparral, the California Chaparral is
characterized by woodlands and grasslands along with the prominent shrubs
covering the ground.
-The California Chaparral is more desert like than its Mediterranean
counterpart.

The Estuaries Biome
What is an "estuary?"
Well...
An estuary is a body of water that is partially enclosed, where freshwater from rivers and
streams mix with salty sea waters.
Estuaries can go by many different names such as bays, lagoons, harbors, inlets
and sounds.
Estuaries make for a home that can support a wide variety of life. Estuarine
environments are among the most productive on earth, creating more organic matter
each year than comparably-sized areas of forest, grassland, or agricultural land.
Fun Fact: The
Hudson Bay is an
example of an
estuary biome.

Don't worry. We have all the info sorted out for
you. Just head on over to the next slide.
Physical Features
Because estuaries aren't limited to any one climate, the characteristics of estuaries
can vary quite a bit. The basis for an estuary is that it is the merging of a freshwater
body with a saltwater body.
Plant
Animals
Plants
The waters of an estuary is subjected to many salinity level changes
due to tides so it is important for the plants to be able to adjust
themselves accordingly. Plants such as these are known as
euryhalines.
Return to the
selection
screen
It takes quite a bit of energy to adjust to the ever changing salt
levels so the plants here have developed special characteristics to
survive. For example, the smooth cordgrass has developed special
filters in its roots to expel the salt that it might absorb while taking
its fill of water.
Return to the

Animals
Plants aren't the only ones here who have to put in the extra effort to surive; the
animals have to do their own work as well. Oysters and blue crabs are a prime
example of this.
But there is more than meets the eye in
this biome! This place is just crawling with
a plethora of microorganisms!
Birds and other critters that love bugs
and fish can thrive fairly nicely in these
areas.
Invertebrates eat these microorganisms which are then eaten by
fish. And as we said earlier, this makes it the perfect place for
birds and other fish loving creatures!

Question 1:
Most cacti have a special adaptation and
thus are known as CAM plants. Which of
the following is the reason as to why cacti
have this type of adaptation?
a) it helps them conserve water
b) it prevents photorespiration
c) all of the above
d) none of the above
Correct!
Congrats! You're off to a good start!

Maybe you should check it over
again...
...just to make sure...

Question
2:
Since vegetation in the chaparral region has adapted by
having fire-resistant roots, how might this help or
increase the survival of a plant or tree?
a) the fire resistant roots give the plant a place to begin the
process of regeneration after a fire
b) the roots store food reserves that also aid in the process
of regeneration
c) the xylem in the roots provide water that helps put out
the fire faster
d) both a and b
e) all of the above
