With its extensive open space Marin is a great place to view native plants. On a hike this weekend on the pacific facing slopes of Mt. Tam, which fall down to the pacific and Stinson Beach, I had a chance to see striking examples of native vegetation. Fir, Madrone, Bay, and Live Oak trees cover the slopes, in sections creating dense woods. Driving at sunset back through the reservoirs of the Marin Municipal Water District (MMWD), dense stands of Redwoods, with an occasional turning Big Leaf Maple, cast a deep shade. In sections along the roadway and trails, the thin inflorescence of native grass can be seen. Seeps and shady grottoes provide refuge for Juncus reeds and ferns. What makes it all more remarkable is to look to the south and see the densely packed buildings of San Francisco, and realize the great accomplishment of preservation Mt. Tamalpais State park and the Golden Gate National Recreation Area represent.
