Red Car Canyon: Oak Trees Bloomed In October, Drought Adaptation

*Stuff you missed this year...
Photo: Diane Edwardson, October 7, 2015.  Coast Live Oak Trees were the first of three native tree species we documented blooming way out of season.  Normally they bloom February through April.  (Click on photo to enlarge.)

With four years of extreme drought, I guess the native trees took that 3" of rain as springtime, just in case it didn't rain again.  The bloom was nowhere near as full as the spring bloom.  Coast Live Oaks on the Red Car Property have not produced acorns in the couple of years, despite lots of pollinators.  

It seems as if they don't bother reproducing in times of drought since the mature trees are conserving every drop of water.  It makes sense as a survival strategy, as mature trees would be more likely than saplings to survive a prolonged drought.  Two other native trees began blooming shortly after the oak trees, California Black Walnuts and Toyon.
