California releases over 3,000 endangered mountain frogs into wild

Wildlife authorities in California have successfully released over 3,000 endangered mountain yellow-legged frogs into their natural habitat, marking a major step in the recovery of a species pushed to the brink of extinction. The frogs, bred in captivity through coordinated conservation programmes, were introduced into suitable mountain ecosystems where populations had been decimated in recent decades.

The mountain yellow-legged frog, once abundant across California's Sierra Nevada and other mountain ranges, has experienced catastrophic population collapse due to the spread of chytrid fungus, a pathogenic disease that affects amphibians globally. Habitat degradation, introduced predatory fish species, and climate change have further compounded the species' predicament, leaving wild populations critically endangered across much of their former range.

The breeding and release programme represents collaboration between state wildlife agencies, research institutions, and conservation organizations working to prevent the species' extinction. Captive breeding facilities have maintained genetically diverse populations while scientists have worked to identify and protect mountain lakes and streams suitable for reintroduction.

Conservationists stress that ongoing monitoring and habitat restoration remain essential to ensure the long-term survival of released populations. The initiative underscores the critical role of coordinated, science-based conservation efforts in addressing amphibian declines, a global biodiversity crisis affecting species worldwide.
