Rare frogs returned to San Gabriel Mountains
Six biologists shouldered backpack coolers filled with 200 federally endangered frogs on Thursday morning and started trudging uphill across three miles of roadless wilderness on the northwestern flanks of the San Gabriel Mountains. The inch-long juvenile Southern California mountain yellow-legged frogs were being carried on foot to a pair of remote spring-fed streams running through some of the wildest places left in Los Angeles County. … They can attest that in these mountains, the wrinkled slopes, lush canyons and the creatures that inhabit them are all in flux because the climate is changing at an unnerving pace. The most noticeable change has been the disappearance of mountain streams and the effect that has had on yellow-legged frogs — their life’s work.
