Much
of the grasslands are maintained by fires and
the grazing of animals. This removes the old hay
and allows the new plants to grow.
Some
plants have developed special adaptations to protect
them from the grazers, such as poison ivy which
causes rashes when it's touched.
Grasslands
are famous for their beautiful colors in the springtime,
but in autumn they become just as beautiful in
wonderful shades of yellow and brown.
