The Burrowes’ Giant Glass Frog, Centrolene ballux, is listed as ‘CRITICALLY ENDANGERED’ on the IUCN Red List of Threatened SpeciesTM. It can be found in humid mountain forests in the Saloya River Valley in Ecuador and the Pacific versant in Colombia. Sadly, the number of Burrowes’ Giant Glass Frogs is declining rapidly.

This Giant Glass Frog is primarily threatened by changes to its natural habitat. Climate change is thought to have altered humidity levels in their existing habitat, making it less suitable. In addition, its aquatic habitat is threatened by pollution and the introduction of predatory fish species. Human settlements and activities on forest boundaries are also putting this frog at risk.

This Giant Glass Frog can be found in the privately owned La Planada reserve in Colombia. More surveys are urgently needed to determine the population status of this species.
