Endangered Antioch Butterfly Needs a Hand

On a 55-acre lot in Antioch, a few biologists and a crew of volunteers are waging a battle to protect a vanishing bit of the natural world. The cause isn’t easily seen: No whales are threatened and the public isn’t in danger of losing a grove of old-growth redwoods. Instead, an endangered and rapidly dwindling species of butterfly teeters on the brink of extinction. And this week, you can help.

Habitat and Humanity

With millions of people and millions of acres of open space, the Bay Area is a lively, and sometimes uneasy, blend of wild and urban. In the East Bay, dozens of rare species — from birds along the Bay to wildflowers in the hills — survive against the odds thanks in part to the East Bay Regional Park District, whose staff does everything from creating nesting islands to clearing trees for the sake of imperiled plants and animals.

Public Transit and Other Endangered Species

Might the streets we travel have once been migratory corridors for other species, now displaced and threatened by our urban ways? Did butterflies pass by this way, looking for mates, or did salmon swim up a creek long since buried? Could we once again share this landscape and these corridors with other species, if our own daily migrations became more communal–a few buses in place of a swarm of cars, a single train where SUVs now reign?

The Saved and the Dammed

For better and worse, the upper reach of the Pilarcitos watershed on the Peninsula was dammed to supply water to San Francisco in the 1860s. The surrounding land has been protected and kept off-limits to the public ever since, allowing rare species to thrive here. That includes the marbled murrelet, which nests only in old-growth conifers, such as Douglas fir. But the dam and other impacts also leave less water in the creek for oceangoing steelhead. Now, a diverse group of stakeholders has come together to chart a brighter future for the fish and the creek.
