Redwoods at Phleger Estates in San Mateo
Redwood forests are dark and quiet places found from Monterey County to Southern Oregon. One of the few patches in Golden Gate that survived the gold rush and the rise of San Francisco Bay as a metropolitan area is at Muir Woods. There are also redwoods in the Phleger Estates in San Mateo county. Two trees are characteristically associated with coast redwood, tanbark oak and California bay laurel. Redwoods need moist areas in valleys or near springs to support their legendary height. In the understory shrubs such as hazelnut, thimbleberry, western azalea and wood rose are common. Wild ginger, trilium, redwood sorrel, sweet coltsfoot, elk clover, and sword ferns give ground cover and wildflowers. Wildlife may seem rare or absent entirely. Many forest creatures live high in the forest canopy (such as the grey squirrel and Sonomoa chipmunk) or deep in leaf litter on the forest floor such as the California giant salamander, slender salamander, and rough-skinned newt. Raccoons and grey foxes seek shelter in hollows in trees and logs. Deep wooded canyons are specialized habitat. There are few insects, repelled by the tannins in Redwood bark, and the deep shade limits the number of flowers and fruit produced. Few food sources mean few bird species, although the old growth forest does support the endangered spotted owl.
