The drought in California is so intense that even trees can't cope anymore.

Sacramento is called the "City of Trees" for good reason, but a lack of rain and state imposed watering restrictions could be taking a toll on the urban forests around the region.  

For example, the UC Davis tree expert tells the Sacramento Bee that just last year a little more than 200 trees died because of stress from the drought.

In Sacramento, city forestry officials reportedly say the problem isn't as severe, but signs of drought-related stresses, which can ultimately kill a tree, sometimes aren't seen for years.  

The solution is reportedly deep watering three or four times a month, but water restrictions make that difficult.
