In May of this year, Dutch filmmaker Marten Slothouwer and his team trudged up Sumatra’s northern-most mountains with video camera equipment in hand, hoping to capture rare and cryptic species for the world to see. Already the camera trapping initiative, dubbed Eyes on Leuser, has taken incredible footage in the region’s imperiled lowland rainforest, but the group hoped now to capture mountain endemics.
The video below highlights their efforts with over twenty distinct mammals and birds, including nine that are threatened with extinction and four others that are listed as Near Threatened by the IUCN Red List. Notably the initiative captured the Sumatran hog badger, which may be a unique species endemic to the island; the Aceh pheasant; the Sumatran serow; and high-living Sumatran tigers at 2,300 meters (7,545 feet).
Last month, scientists, also using camera traps, confirmed that a small population of Sumatran rhinos still inhabits the Leuser ecosystem. But Leuser is under incredible pressure due to logging, monoculture plantations like palm oil, poaching, roads, and encroachment into protected areas. The forest is the last place on Earth where orangutans, elephants, tigers, and rhinos still survive in the same habitat, though all species are considered Critically Endangered.
