Trees -- Aspen |
Aspen Scars:
The dark scars on the aspen
tree's white bark are caused by elk, deer and other foraging animals that
nibble on the soft inner bark when deep snows bury grasses and shrubs. Besides
chewing on aspen bark for food, elk and mule deer rub their antlers against the
trunks to shed velvet in autumn. Other aspen scars are made by black bears
marking their territory, and woodpeckers creating holes to search for insects
or make nests. If injured or grazed on too severely, some of these aspen trees
will die. Healthy aspens without scars thrive where there are fewer impacts
from wildlife. |
