Desert Biomes
Climate Information
Arid Deserts: Temperature ranges
from 10 to 30 degrees C throughout
the year. However, there tend to be
large daily fluctuations in
temperature – very hot during the
day and very cold at night.
Cold Deserts: In some areas of the
world, there are temperate climates
that receive very little rainfall, such as
coastal and mountain areas.
Antarctica is also considered a cold
desert.
In all deserts, rainfall is less than 25 cm (approx. 10 in.) per year.
Plants in the Arid Desert
The dominant plants in the desert are
succulents, which have stems and leaves
covered with a waxy coating, which helps
them store water.
Hedgehog Cactus
Saguaro Cactus
Joshua Tree
Aster
Barrel Cactus

Threats to the Biome
Urbanization
Global Warming
In many places, the desert
is being converted to
housing developments
and golf courses.
The polar ice caps that
make up the cold deserts
of Antarctica are slowly
melting, changing ocean
temperatures, salinity, and
sea level.
Lack of Water
As cities along the west coast become
more populated, they draw water away
from their natural sources, including the
desert Southwest.
