Red Car Property: Not A Park, It Just Looks Like One. Native Black Walnut Tree Update

Photo: Jonathan Vandiveer, February 26, 2016.  We've been documenting the same California Black Walnut Tree since 2000. (Despite the encroached fence, the large tree on the right is on the Red Car Property.)

Four years of unprecedented drought has taken its toll on this once spectacular tree.  It's early in the season yet, but it is sprouting new growth close to the trunk and larger branches.  The protected native tree, like so many other trees, have been growing out of season due to the unheard of 3" of rain we had on one day in September

Due to the orientation of the hillside blocking afternoon sun on this part of the Red Car Property and Riverside Drive, California Black Walnuts tend drop their leaves late in December and sprout new growth later than the rest of the property.  It's hard to say what's normal this year.

Native trees are very well adapted to drought as they evolved with our Southern California drought or deluge cycles of rain. They also help hold our steep hillsides together when it does rain.
