Exploring Nature in the San Francisco Bay Area

Whispers in the Water

By a quiet picnic area in the Presidio, water gurgles out of the hillside, spills over brick walls, and disappears underground on its way north to Crissy Field and the Bay. This is El Polin Springs, celebrated by the Ohlone and the Spanish for bringing fertility to anyone who drank of it. Ambitious plans to uncover the watershed's stream channels are peeling back interwoven layers of human and natural history to reveal a complete urban watershed.

Carquinez Breakthrough

The open hills along the Carquinez Strait are home to working ranches and open space preserves that are meeting places for native species from both the coast and the Central Valley. Today's quiet pastoral landscape makes it hard to envision the violent formative flood that may have cut this critical waterway between the Bay and the Central Valley some half a million years ago.

Edward Ross has visited every continent except Antarctica in pursuit of his passion for studying, collecting, dissecting, classifying, naming, photographing, and deeply appreciating insects. In between his globe-trotting adventures, the 89-year old curator emeritus of entomology at the California Academy … Read more

Ubiquitous Eucalyptus

Some folks love their scent and shade; others resent them for crowding out natives; most of us know they came from Australia and found a niche here. But few know that the East Bay’s eucalypts owe their presence to one entrepreneur who thought the trees would make him rich. They didn’t, but now, love them or hate them, the trees are here to stay. Fortunately, some animals have profited from Mr. Havens’s mistake.
