There are about three thousand California clapper rail birds left in the world, almost all live in the San Francisco Bay. The birds have taken to nesting and feeding amidst a tall grass, the non-native spartina, which is being eradicated
U.S geological survey biologist Mike Casazza says over time native plant restoration will help the clapper rails. In the interim he has been helping out the endangered birds with artificial islands, giving them a place to nest and feed.
RAILS1A (CASAZZA): If you can provide them that cover during the wintertime you can get through that period where they are kind of exposed. And that is where sort of some of the innovative things that we have come up with is these artificial islands which actually provide cover and refuge for the birds at any tide."
Casazza is presenting a research paper on the clapper rails at the state of the estuary conference.
