Standing sentinel near the highest point in the East Bay Regional Park District, an ancient blue oak is our window into a spectrum of life in the orbit of one grand tree. From passing raptors and nesting acorn woodpeckers and browsing deer, we zoom in to the strange and colorful world of the gall wasps. These tiny insects are first-rate engineers, manipulating their host trees into creating peculiar shelters for the wasps' larvae, in often-fanciful shapes reminiscent of sea urchins, dunce caps, and more.

Ask most people to name the most important species of our grassland habitats, and they'll probably pick coyotes, golden eagles, or even rattlesnakes. But experts say that the strongest contender of all is the animal eaten by all those other ones: the lowly California ground squirrel, a true keystone of local grasslands. Belowground, the squirrels' lengthy burrows harbor insects, snakes, owls, and even frogs and salamanders that couldn't live in such a dry landscape without the squirrels' help. And above-ground, they've evolved some unusual defenses that allow them to thrive, even as they feed so many others.

Mention extinct species, and most people think of long-gone mastodons and saber-toothed tigers. But we know that some Bay Area species have disappeared in just the last 200 years. Or have they? Prompted by rediscoveries of lost species in Solano and Contra Costa counties, we decided to see what other missing flora and fauna might still be out there, awaiting a patient observer.

It's almost impossible to imagine the California landscape without oak woodlands. But this most familiar and prolific habitat faces a number of serious threats, including unchecked suburban development and Sudden Oak Death. Fortunately, many parks in the Bay Area, including those of the East Bay Regional Parks, offer welcome refuge for a variety of oak woodlands.
