Nurseries for poison dart frogs dug by feral pigs

Sometimes the key to healthy poison dart frog populations is a pig playing in the mud. From BBC Earth:

Typically, female poison dart (dendrobatid) frogs lay eggs on land. Once the tadpoles hatch, male frogs, their fathers, then carry them to small nursery pools. But these pools may be short-lived, and the frogs are too tiny to dig their own. Enter the peccary, a species of wild pig common in Central and South America. Peccaries like to fling turf, specifically by digging out wallows – their own individual mud spas. As they do so, they can radically transform the rainforest floor, creating pools of water that are just the right size for prospective frog parents.
