Why More Trees in the Sierra Mean Less Water for California
With California’s reservoir levels dropping, just about everyone is wishing the state had gotten more water this year. That doesn’t just depend on the weather, according to a team of scientists. Sierra Nevada forests play a big role in the state’s water supply.
Just like crops, trees consume water. And Sierra Nevada forests are denser than they once were after decades of fire suppression. That could be reducing the amount of runoff coming from the snowpack — runoff that provides water for most of the state.
