There is new hope for the Hawaiian tree snail population in Oahu.
Its numbers were rapidly declining earlier this year because of rats. Researchers took the entire population of 24 snails out of the wild and into a lab at University of Hawaii.
This allowed researchers to build an enclosure at the Honouliuli Forest Reserve designed to keep predators out.
The snails are now back in the wild, and officials hope this will help their population thrive
