About sixty-eight percent of all native reptiles are endemic to the area (about 160 of 235). The Philippine crocodile, Crocodylus mindorensis, is a freshwater crocodile that is considered the most threatened crocodile in the world and is endemic to the area; it is only found in Mindanao, Negros, and Luzon. Wild populations in 1982 totaled somewhere between 500 and 1000 individuals. In 1995, this number decreased to a mere 100 individuals. The discovery of a population of this crocodile in the Northern Sierra Madre on Luzon gives hope for its conservation. Active in the conservation of Crocodylus mindorensis is the Crocodile Rehabilitation Observance and Conservation (CROC) Project of the Mabuwaya Foundation.
