Billions of Gallons of Water Saved by Thinning Sierra Forests

There are too many trees in Sierra Nevada forests, say experts from UC Merced, UC Irvine and the National Park Service working at the National Science Foundation Southern Sierra Critical Zone Observatory (NSF SSCZO).

This comes as a surprise to those of us who see dense, verdant forests as a sign of a healthy environment. After all, green is good, right? Not necessarily. When it comes to the number of trees in California forests, bigger isn’t always better.
