Photo: Diane Edwardson, July 27, 2015. The inch of rain from Tropical Storm Dolores, accelerated the new growth sprouting from the trunk and thicker branches of the same California Black Walnut Tree we highlighted in yesterday's depressing post about the effects of the drought on even the hardiest of trees. (Click on photos to enlarge.)
Photo: Diane Edwardson, July 27, 2015. Considering branches began falling off this tree in July, it is a ray of hope. California Black Walnut Trees evolved to fit our all-or-noting rain cycles in the state. They have very deep root systems to store water for the drought years. But even the largest trees are beginning to suffer. This tree is not dead.
Photo: Diane Edwardson, July10, 2015. Before brush clearance contractors whacked away at all the new growth at the base of all the trees on the Red Car Property, you could even see this particular growth pattern on Native Black Walnuts that appeared to have died, (like the trees below Lake View where the fire occurred last October*).
Black Walnuts' and other native trees' root systems are so deep, they help hold hillsides together, which is critical for the way it rains in Los Angeles.
California Black Walnuts are protected native trees and you need a permit from the City to cut them down, even if they are dead.

*As with all things Red Car Property, the Black Walnut story became complex. We'll follow up on the trees below Lake View next week.
