In many areas, the ground-dwelling
northern pocket gopher (Thomomys talpoides) survived the eruption in the
safety of its burrow.
In many areas, the ground-dwelling
northern pocket gopher (Thomomys talpoides) survived the eruption in the
safety of its burrow.
After the eruption, gophers
survived by burrowing through the ash and feeding on the roots of
surviving plants.
As the gopher burrows, soil, seeds
and nutrients are brought to the surface.
These mounds of soil and ash
provide good places for wind blown seeds to grow.
The deer mouse (Peromyscus
maniculatus) survived in many areas
which were protected from the blast. These areas were either behind
steep ridges or beneath snow cover.
The deer mouse thrives in this
harsh environment because it is so adaptable. It eats whatever food is
available and can find shelter among the blowndown trees.
The deer mouse is a crucial link in
the food chain. It becomes food for coyotes, hawks and owls.
