Fallen Giants and Forest Openings

As these trees get older, some can no longer withstand winds and rain. These trees give up their spot in the sun and fall to the forest floor.

This tree fell in March 1991. Over the years, large trees have fallen in this area, creating an opening in the forest canopy. Windthrow (the blowing over of trees) is a leading cause of Coast Redwood death. A transformation is occurring as mature trees give way to young trees. These young trees have remained almost dormant in the shadows of the giants for many years, waiting for their chance in the sun.

In larger openings, trees and plants requiring more sunlight are able to grow. Eventually, the young redwoods grow high enough that the forest canopy is again dominated by redwoods. This whole process is called plant succession.
