Photo by @joelsartore | Sensitive to changes in the environment, northern leopard frogs in the Rocky Mountain region of North America have been experiencing population declines, prompting the creation of the Northern Leopard Frog Recovery Team. This team, which is dedicated to ensuring the survival of this species, has been breeding the northern leopard frog for six years–an effort that has resulted in the release of more than 7,100 frogs. In June, the Vancouver Aquarium (@vanaqua) raised and released over 1,600 tadpoles back into the wild, which was the second largest number of tadpoles produced in a single year. In recent years members of the recovery team have been able to hear adult males calling at the release site, a good indicator that the frogs are surviving the winter months and reaching sexual maturity.
