The Mascarene Ridged Frog lives in humid savannahs and open forests all across African and various islands including Madagascar. There are only two species of frogs that are not endemic (only found on) to Madagascar, the Indian Bullfrog (xxxx) and the Mascarene Ridged Frog.
It is believed that the Mascarene Ridge Frog got to Madagascar from Africa on a raft of some sort before humans arrived but after Madagascar split from Africa. The frog is named after the Mascarene Islands which the frog is not native to. It is believed that the frog was introduced to the islands in the late 1800’s.
The International Union for the Conservation of Nature (IUCN) Red List assesses the Mascarene Ridged Frog as Least Concern for Extinction. The frog has a wide range and a presumed large population.
