Orange County Chompers: The Western Spadefoot
WEDNESDAY JAN 05 2011
Orange County, California, of course. And we're talkin' toad.

The western spadefoot toad (Spea hammondii) is a three-inch long, rotund little amphibian noted as a "species of concern" by the U.S. Fish and Wildlife Service. It's got big pupils that expand and contract like cat eyes, and it secretes skin mucus that smells like peanut butter.

It's also one of many amphibian, reptile and small mammal species that USGS biologists are studying on lands managed by the Irvine Ranch Conservancy, a nonprofit nonadvocacy organization that manages some 50,000 acres of the historic Irvine Ranch.

WERC's San Diego Field Station has been working extensively on lands managed by the conservancy since 2005. Station biologists Sara SchusterLiz Gallegos and Adam Backlin are based in Irvine, and they work with conservancy colleagues to study the ecosystems of the Irvine Ranch Natural Landmarks -- which is recognized by the U.S. Department of Interior National Natural Landmarks and the California Natural Landmarks programs.

You can learn more about USGS projects on Irvine Ranch Conservancy lands in their latest newsletter: http://activities.irconservancy.org/Winter2010Partner
