LOS GATOS, Calif. (KGO) -- California's historic drought is creating some drying times for the giant sequoia trees.
For the first time in at least 125 years, giant sequoias in the Southern Sierra Nevada mountains are showing significant loss of foliage.
UC Berkeley scientists took part in a research project examining the effects of the drought on giant sequoias.
The trees can live to be well over 3,000 years, if they get enough water and nutrients.
It is the largest single-stem tree species in the world.
