Dear SAVE THE FROGS! Supporter,

At one time a common sight throughout the California's Sierra Nevada mountains, the Yellow-Legged Frogs are now completely extinct from over 90% of the sites they once inhabited! Don't despair though: today you have THREE ways you can help SAVE THE FROGS! Thanks for your support!

#1: Register for today's SAVE THE FROGS! Academy Class all about the Yellow-Legged Frogs!

On Wednesday, October 2nd, SAVE THE FROGS! Founder Dr. Kerry Kriger and Dr. Vance Vredenburg of San Francisco State University will discuss California's critically endangered Mountain-Yellow Legged Frogs, and ways YOU can help us save them. Dr. Vredenburg is an expert on chytridiomycosis, Yellow-Legged Frogs, and amphibian ecology, so you do want to attend! The class meets online 11am-12pm San Francisco Time. The class is free; please take advantage of our unbeatable prices and one of a kind subject matter!

Please register for the Yellow-Legged Frog class here.

#2: Please tell the USFWS that you support protections for the Yellow-Legged Frogs and Yosemite Toads!

The U.S. Fish and Wildlife Service (USFWS) seeks your comments on their proposal to list as endangered species the Sierra Nevada Yellow-Legged Frog, all populations of Mountain Yellow-Legged Frogs that occur north of the Tehachapi Mountains, and the Yosemite Toad! They also seek your comments regarding their proposal to designate critical habitat for these species. Please submit your comment today!

Submit your comment on behalf of the frogs here!

I support the USFWS proposal to list as endangered species the Sierra Nevada Yellow-Legged Frog, all populations of Mountain Yellow-Legged Frogs that occur north of the Tehachapi Mountains, and the Yosemite Toad. I also support the creation of vast tracts of critical habitat for these species, as this is a necessary step towards their recovery. Thanks to the USFWS for helping SAVE THE FROGS!

#3: Donate to SAVE THE FROGS!

SAVE THE FROGS! has a staff of three people in the USA (and two in Ghana, West Africa). We have a budget 100 times smaller than that of Greenpeace yet we have a multitude of programs all over the world. How do we do that? We do it by using your donations in the most efficient and effective way possible! In 2012, 93% of all donations we received went directly to our frog conservation programs. So please donate today and watch SAVE THE FROGS! continue to do more for the frogs thsan you ever thought possible! THANK YOU!

Hi, I'm the happy donation frog!


VICTORY: A brief history of SAVE THE FROGS! Yellow-Legged Frogs successes

On top of educating thousands of Californians about these frogs, we havewith the help of our supporters helped get important governmental action on behalf of the frogs:

The California Fish & Game Commission voted unanimously on February 3rd, 2012 to grant endangered status to the Mountain Yellow-Legged Frogs. Thanks to the 1,573 SAVE THE FROGS! supporters who sent in letters on behalf of the frogs!

Thanks to the 707 Save The Frogs Supporters who sent letters in to the The National Park Service in November 2009 asking them to remove non-native fish from over 60 waterway in Sequoia & Kings Canyon National ParksOur comments comprised over 95% of the total comments received by the Park Service! The NPS is currently developing an action plan for removing the non-native trout (if any NPS employees can update us on the status of their efforts, please let us know!).

Educating the public about the plight of the Yellow-Legged Frogs

SAVE THE FROGS! nominated and wrote the section on the Sierra Nevada Yellow-legged Frog (Rana sierrae) and the Mountain Yellow-legged Frog (Rana muscosa) in the Endangered Species Coalition's report Water Woes: How dams, diversions, dirty water and droughts put America’s wildlife at risk in an effort to bring awareness to the array of threats these species face in the Sierra Nevada of California. The introduction of invasive species and contaminated water by pesticides and pollution has resulted in both species disappearing from 93% of their historic range. This clearly indicates there is something drastically wrong in their environment.

Extinction Biology: Yosemite Toads (1974-1982)

I wrote about the Yosemite Toads in the introduction to my Ph.D. thesis:

"An increase in the female:male sex ratio within a declining population is an epizootiological feature consistent with chytrid-related mortality events (Kagarise Sherman & Morton 1993, Lips 1998, Muths et al. 2003). For instance, Kagarise Sherman and Morton (1993) recorded a nine-fold decrease in the numbers of male Yosemite toads (Bufo canorus) at Tioga Pass, California between 1974 and 1982; females showed no decline in this same time period. Retrospective examinations of preserved specimens revealed that this population was chytrid positive (Green & Kagarise Sherman 2001). Kagarise Sherman and Morton (1993) hypothesize that the sexually dimorphic pattern of decline was due to life history characteristics that likely exposed the male toads to more aquatic pathogens: males spent twice as much time in the breeding pools, and were twice as likely to return to the breeding pools in multiple years. Muths et al. (2003) observed similar life history characteristics in a population of Bufo boreas whose observed female:male sex ratio changed from roughly 0.12 to 2.8 after a chytridiomycosis-linked decline. This trend however is not restricted to species with aquatic breeding habitats: Bell et al. (2004) found a significant increase in the proportion of female Leiopelma archeyi after a decline they suspected to be caused by chytridiomycosis."

"In order to save the frogs leaping by fresh water ponds 
We can't just wave our magic wands;
We must take action
To see a reaction.
Even though these words are succinct,
Frogs need our help to keep from becoming extinct."

"Dear Dr. Kriger, My name is Jenna and I am 10 years old. I want to be a herpetologist and study frogs when I grow up. Thank you for making SaveTheFrogs.com, it's awesome. I have loved frogs pretty much my whole life so I am extremely glad other people care about frogs too. I am really jealous you got to go to so many different places and see different frogs. I hope to join you on an expedition some day. I am so excited to be a member. Yay! I also want to start a Save The Frogs chapter at my middle school this year. If you have any tips please let me know because I have no idea where to start. Frogs forever, Jenna"

Frogs are the most threatened group of animals on the planet: nearly 2,000 of the world's amphibian species are threatened with extinction and at least 150 species have entirely disappeared since 1979. SAVE THE FROGS! is America's first and only public charity dedicated exclusively to amphibian conservation. Your generous financial support makes our work possible!
