Sydney’s Taronga Zoo has announced the “monumental release” of 544 critically endangered northern corroboree frogs into Brindabella National Park, west of Canberra—marking the largest release of the species to date.
The four-month-old juvenile frogs were bred in captivity as part of the zoo’s conservation program. It’s estimated that just 1,200 northern corroboree frogs remain in the wild.
