The Sierra Nevada yellow-legged frog is making a comeback after nearly disappearing from California's alpine lakes

The frog was once the most common amphibian in the Sierra Nevada, but was nearly wiped out by the chytrid fungus

The silence that followed took its toll on the wider ecosystem - and conservationists knew they had to act

Now, after years of dedicated work, the frogs are making a remarkable comeback, breathing new life into Yosemite's wilderness

In 2006, Yosemite National Park began reintroducing frogs into fishless lakes

In 2007, the park began removing non-native fish from remote sites to restore the frog's habitat

Scientists have transported frogs that appear to be resistant to the fungus to other lakes

A 2016 survey found that the frog population had increased sevenfold

Scientists say the reintroduced populations have a strong chance of persisting for at least 50 years
