Frenzel Creek Research Natural Area

Original Publication DATE: 5/26/2011

The first journey of the summer has begun and as I make my way south to the Sierra San Pedro Martir botanically diverse destinations will craft the route I drive. The first stop was not too far from home, but a place I had not yet been. The serpentine soils along the Frenzel Creek Research Natural Area foster the sympatric overlap of two cypresses–along with many other unique serpentine plants. Enjoy the photo-blog, as I won’t have a lot of time to write with many miles to travel.

  1. Would you happen to recall if/where you might have noted sizeable populations of Heianthus exilis sunflower? Haivng spent 37 years in the USDA studying sunflower, I’m still trying to track down interesting species, like H exilis. I assume there are no trails in this RNA and one must blaze away.

    1. Thomas- it’s been far too long since I’ve visited this place so I do not remember any sunflowers at this time. And yes you do have to blaze your own trail!

      1. Thanks. Did not expect a reply, esp one so soon. Thanks for taking the time to answer.
