At 11 a.m. Tuesday, the wildlife experts opened their aquarium bags and gently released 500 Southern mountain yellow-legged frog tadpoles reared at the Los Angeles Zoo into a knee-deep stretch of Big Rock Creek where theyve been absent for half a century.
It offered all the creature comforts the inch-long amphibians will need to metamorphose into frogs and produce new generations in the wild: cascading spring water and snowmelt edged with alders and buzzing with insects to feed on.
And away they go, Ian Recchio, curator of reptiles and amphibians at the Los Angeles Zoo, said with a smile as the tadpoles started bulking up on algae. I think these guys are going to like it here.
As an added precaution, biologists had eliminated fresh water perils such as predatory fish and crayfish that could tear them apart.
