Exploring Nature in the San Francisco Bay Area

In the Shadow of Giants

The hills above Oakland once held some of the largest redwoods ever seen, one estimated at 31 feet in diameter. Ten million years ago, such trees towered over much of North America. Nothing in this long history prepared them for the coming of men, armed with axes and saws, who felled all of Oakland's redwoods in just 15 years. But even second- and third-growth redwood forests hold their charms, not to mention the subtle suggestions of the forests they can once again become. And you don't have to go too far from downtown Oakland to find them.

Dredging up an Avian Oasis

What do you get when you scoop up 250,000 cubic yards of muck from the Petaluma River? Prime shorebird habitat, of course. Unlikely as it may seem, Shollenberger Park is a place where birders have spotted 150 bird species, from nesting avocets and stilts to harriers and egrets. And a new addition to the park will make it one of the largest publicly accessible stretches of wetlands in the Bay Area.
