In search of the rare Tiburon Mariposa Lily Calochortus tiburonensis, we went to Ring Mt.,which is part of the Marin County Open Space District. We followed “Bay Area Hikers” suggested route: http://www.bahiker.com/northbayhikes/ringmountain.html
The route is scenic and views include San Francisco Bay, San Francisco, and San Quentin prison. Much of the preserve is grasslands which are now dried and brown. The trail started out with a number of alien plants such dandelions and mustard, there were soon many native species still in bloom. Most plentiful was Common Madia. Lots of dark butterflies were flying around but never landed or opened their wings for more than a fraction of a second. Best guess is they were Ox-eyed Satyr. Upon getting home I found on the internet an old Calphoto posting from May 27, 1998 by Arnel Guanlao that listed most of the flowers I had seen and was most helpful with plant identification: http://calphoto.com/ring.htm As it was windy and midday I only took a compact camera today. Here are a few photos to give you an idea of some of what I saw.
Ring Mt. is a preserve and its mission is to help protect natural places including the plants and animals that are found there. If you find the Mariposa Lily, please be extremely careful as it is rare and endangered. This is the only place in the world it can be found!! I have noticed people picking wildflowers my last two times at Ring Mt. fortunately none were picking the rare ones. Picking wildflowers on public lands is illegal, results in there being less seed to produce plants next year and most wildflowers never make it home or die very quickly as they don’t last long when picked.
