Site Description: Fire has a devastating effect on alpine vegetation, as can be seen in the dramatic fire scar (left) and the dead Pencil Pine stags (right) more than 30 years later.  Recovery is slow because the alpine vegetation is poorly adapted to fire, soil is thin and subject to erosion after fire, and growth rates of alpine vegetation (especially the gymnosperms) is very slow.
