Tucked into less than a square mile of land next to a freeway, the Peninsula’s Edgewood Park is a showcase for stunning wildflower diversity, all the result of our region’s unique geology.
The Courtship of Herons
All around the Bay Area in spring, herons and egrets begin their annual transformation from mostly solitary top predators to birds gathered in crowded breeding colonies. Local photographer Philip Greene has spent years following the whole subtle and spectacular process by which these large birds break down their resistance to social communion: the changing color of bills and legs, the growth of flowing nuptial plumage, and the complex gestures and dances that make up the fine art of getting to know one another.
Purple Needlegrass Takes Root in the Capitol
David Amme, author of “Grassland Heritage” in Bay Nature’s April-June 2004 issue, called purple needlegrass “the undisputed candidate for official state grass.” Now that may soon become literally as well as figuratively true: State Sen. Michael Machado, D-Linden, is sponsoring … Read more

Letter from the Publisher
I wonder if the rest of you will be as surprised as I was to learn that the area around Fifth and Mission Streets in San Francisco used to be dominated by sand hills, some at least 40 feet high. … Read more
Why do mushrooms come in so many shapes and colors?
In technical terms, mushrooms are the charismatic sexual reproductive structures of fungal individuals whose main body (fine, cobweb-like filaments called hyphae) is well hidden in the soil or amongst leaves and rotting wood. The primary role of the mushroom is … Read more
Out in the Tules
The rounded hills by the Bay are the first thing that catch your eye at Coyote Hills Regional Park. But the brackish and freshwater marshes behind the hills have a charm of their own. Remnant of a once-extensive mix of tidal and freshwater wetlands that sustained a thriving Ohlone community for several thousand years, the marsh is now home to marsh wrens, muskrats, and one of the East Bay’s few remaining patches of tules.
Where the Elk and the Antelope Played
A million years ago, in a climate much like ours today, the land around an ancestral bay teemed with large animals: mammoths and saber-tooth cats; bears, horses, and peccaries. By 300 years ago, the mammoths were gone, but grizzlies, elk, condor, and pronghorn were abundant.European settlers wiped out many of those animals, but programs to reintroduce some of them are now under way. Which raises the question: What should a healthy, native megafauna look like now?
