Purple needlegrass may soon gain recognition as one of California’s official state symbols, like the golden poppy, our state flower since 1903. For native grass advocates, “the hope is that a new state symbol might draw some public attention to … Read more

The classic image of a redwood forest is one of stately tall trees, dense shade, and lots of green. The columnar trunks of the giant trees draw our gaze up to the high canopy, but if we follow them down … Read more

In the Shadow of Giants

July 1, 2004 •  by

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.

When Spanish explorers first saw the San Francisco Bay in 1769, they found a land cloaked largely in perennial grasses. But the extirpation of the native elk herds that grazed the land, the introduction of cattle, and the incursion of European annual grasses abruptly and dramatically transformed the landscape into the familiar green hillside carpets that turn into brown thickets in summer. Today’s grasslands, altered as they are, still produce some beautiful wildflowers, lots of wildlife, and if we look closely, remnants of the native bunchgrasses of yore, which can be enhanced with careful management. The parks of the East Bay hills are a good place to start looking for that mix of the grasslands of yesterday and today.

It turns out that some of the Bay Area’s showiest wildflowers are also parasites that draw water and nutrients from their neighbors.

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
