7 - Valley Oak and Pump Station

To your left stands an impressive Valley Oak, likely between 150 and 200 years old. Valley Oaks are native to California and are among the largest and longest-living oak species in the state. They begin life as a single acorn, which falls from the tree in autumn. If conditions are right—moist soil, space, and sunlight—the acorn germinates and sends down a deep taproot, allowing the seedling to access water even during dry summers. Over the decades, the tree develops a wide-spreading canopy and a thick trunk. Growth is slow, but Valley Oaks can live for several centuries if left undisturbed. Nearby, the pump station plays a modern role in sustaining the landscape, delivering water from the slough to the managed wetlands east of the trail, helping to maintain vital habitat for wildlife.
