MOUNT HARRISON INTERPRETIVE AREA
ALPINE ECOLOGY
LAND ABOVE THE TREES
The alpine environment is one of the harshest on earth. It has low temperatures, hight winds
(up to 130 miles per hour), intense sunshine, and a short growing season. Many of he plants and
animals have unique features which help them to survive in these extreme conditions.
ALPINE PLANTS
Plants in the alpine ecosystem are often shaped by their environment; they look different from
plants at lower elevations. As a matter of fact, vegetation at this elevation can look "other-worldly."
"Krumholz" or elfin timber are terms used to describe the gnarled, stunted trees in this area.
Many plants are very small—some less than the size of a penny.
Others are cushion-shaped so the center stays warm and wind is deflected over their mounds.
Some appear grey-green because they are covered with dense hair, which helps to reflect
the sun and minimize water loss.
WILDLIFE
Although alpine areas are often tough environments, they are home to many animals.
In the summer at this elevation you can see mammals such as deer, mountain lion, coyotes,
chipmunks, and numerous species of birds. Migration and hibernation are two ways animals
survive. here. For example, in the spring, sage grouse often migrate from their traditional
breeding grounds to hgher elevation sagebrush sites. In the fall, sage grouse, as well as many
other animals, migrate to lower elevations or hibernate to escape the harsh weather.
