Trees do plenty of work to sequester carbon on their own, but many forests are not as healthy as they should be due to fire suppression and climate change. This can leave trees vulnerable to large scale insect damage, fire or drought, and much of the carbon stored by forests is lost to the atmosphere as trees die.
Drought, especially prolonged or severe drought, can be a major stress in forest ecosystems. Drought can kill trees directly or indirectly through insect attack or wildfire. Both of which are more likely to occur during drought.
“A mature Giant Sequoia can use 500-800 gallons of water every day during the summer,” said Anthony Ambrose, a tree biologist at U.C. Berkeley. “That’s a lot of water necessary for just one tree.”
One of the greatest natural events in the world is starting to change — change colors that is. The brilliant colors on the leaves of millions of trees are about to make you look up in awe and the U.S. Forest Service wants folks to get outside and experience it this Fall.
