It may be alarming to see these forests on fire, but research funded by your gifts shows that disturbances such as these actually are good for giant sequoias. Learn more about this research.

Yet these green specks grew into giant sequoias two years after seeds were strewn in canopy gaps. This species of titan tree has stagnated in regeneration efforts for nearly a century.
