Restoring Aramburu Island

July 01, 2011 by Aleta George

Aramburu Island sounds like it might be in the South Pacific, and until recently, it was about as noticed locally as some distant atoll. But then in 2007, in the wake of an oil spill, folks from Tiburon Audubon discovered that this humble island in Richardson Bay was a major refuge for injured birds. Now, they’re hoping to make it good habitat for healthy birds and other wildlife too.

July 01, 2011 by William Keener

When William Keener got a report of a harbor porpoise inside San Francisco Bay in 2008, he knew this was big news: They had been absent since World War II. Now, Keener's group of researchers has turned the Golden Gate Bridge into a world-class wildlife observatory where anyone can see porpoises in action. Why have they returned? Did Bay cleanup efforts make the difference? While we can't know for sure, we can celebrate this rare case of a large mammal reintroducing itself into its former habitat.


A Good Season for Bay Herring

March 01, 2011 by Juliet Grable

Each winter, a strange spectacle takes over San Francisco Bay. You'll see evidence of it: moving rafts of agitated birds; strings of cormorants; pods of sea lions; plunge-diving pelicans. And fishing boats out on the Bay. But you won't see the cause for this excitement: thousands of herring en route to their spawning grounds. This year's season has been pretty good, but some folks think we should still go lightly on the lowly herring.
