The Foothill-Yellow Legged Frog (Rana boylii) is an amazing amphibian species that lives in and near rivers throughout California. The species is under threat from hydroelectric and water diversion projects that alter the river's water temperature, timing of floods, and streambed characteristics. Droughts in California exacerbate the problems for these frogs. Invasive American Bullfrogs prey on Foothill Yellow-Legged Frogs and compete with them for habitat and food.
Since 2010 SAVE THE FROGS! has been working to save these frogs via various campaigns described below. We appreciate your tax-deductible donation to SAVE THE FROGS!, which enable us to continue saving these beautiful creatures from the multitude of threats they face.
In 2015, SAVE THE FROGS! succeeded at preventing the City of San Francisco's attempts to destroy portions of the Little Yosemite Canyon (a section of Alameda Creek, southeast of the San Francisco Bay). We are very excited to have protected this critical frog Foothill Yellow-Legged Frog habitat.
Please download the following PDFs to get an in-depth look at San Francisco's destructive plans and how SAVE THE FROGS! won this campaign.
- This article provides a great introduction to Foothill Yellow-Legged Frogs and our campaign to save them at Alameda Creek (September 2015):

- This appeal triggered governmental action that eventually led to San Francisco halting their efforts to destroy sections of Little Yosemite Canyon (December 15, 2014):
SAVE THE FROGS! appeal of the San Francisco Planning Commission's determination that the Little Yosemite Fish Passage Project will have no significant effect on the environment.
- SAVE THE FROGS! submitted this letter to the City of San Francisco's Planning Department on July 29, 2015:
The Impact of the Proposed Alameda Creek Recapture Project on California's Native Amphibians
- On behalf of SAVE THE FROGS!, environmental attorney Michael Graf submitted this letter to the City of San Francisco and significantly accelerated the closure of the City's anti-frog construction plans in Alameda Creek (September 3rd, 2015):
Michael Graf's Letter to the City of San Francisco
- Based on Michael Graf's letter 11 days prior, the City of San Francisco on September 14th, 2015 abandoned its plans to destroy Little Yosemite
Creek - and agrees to refund SAVE THE FROGS! the $521 appeal fee we had paid.

Though the City of San Francisco did not provide a budget for their proposed project, we estimate it would have cost the taxpayers between one and three million dollars. These millions are now freed up to be spent on projects that actually contribute to social and environmental improvements.

Would you want your tax payments funding the spraying of pesticides on you, your family and your local frog populations? On September 3rd, 2015, SAVE THE FROGS! sent this letter to Alameda County to urge them to halt their mosquito spraying program.

SAVE THE FROGS! is actively working to protect the amphibians of Tesla Park. This biologically rich area is threatened by expansion of off-highway vehicles from nearby Carnegie Vehicular State Recreation Area (60 miles east of San Francisco). Please visit the STF! Tesla Park page and also the Save Tesla Park page to learn more and get involved: we need your help to win this campaign and save the Foothill Yellow-Legged Frogs!
Thank you to the 453 SAVE THE FROGS! supporters who sent in letters to the Off-Highway Motor Vehicle Recreation Division of CA State Parks in 2015 urging them to cancel their plans to expand into Tesla Park.
A message from Celeste M. Garamendi (Friends of Tesla Park):
"Thank you for considering sharing our efforts to preserve this irreplaceable natural and cultural landscape."
SAVE THE FROGS! has submitted to letters to the US Fish & Wildlife Service urging them to protect Rana boylii under the Endangered Species Act, one related to tesla Park and one related to Alameda Creek:
(1) Please read this letter that SAVE THE FROGS! along with our partner groups submitted to the United States Fish & Wildlife Service on August 13, 2015 (related to the frogs at Tesla Park).

SAVE THE FROGS! thanks the Alameda County Fish and Game Commission for supporting our investigation of fungal disease in the Foothill Yellow-Legged Frogs of Alameda Creek.
Non-native American Bullfrogs eat Foothill Yellow-Legged Frogs, spread diseases like chytridiomycosis, and compete with Foothill Yellow-Legged Frogs for food and breeding habitat. Read all about our efforts to stop the importation of millions of bullfrogs into the state.
"You might want to add a link to this other great page that the US Forest Service has put together on Rana boylii in case people want to read more and see photos of habitat in other rivers around the state; there is a good bibliography on boylii too."
