African savanna elephants are the largest terrestrial mammal on Earth. Though they once roamed throughout sub-Saharan Africa, their range has become increasingly small due to poaching and habitat loss. After rampant demand for their tusks, just 20 super tuskers remain.

Due to decades of heavy poaching, just 400 African forest elephants remain in Cameroon. Like their savannah and Asian cousins, African forest elephants can live for up to 65 years and are considered "gardeners of the forest." Compared to savanna elephants, the forest elephant is in much more serious danger of becoming extinct.

As few as 30 Sumatran rhinos survive in the wild, making them one of the rarest, most endangered mammals in the world. We're working to help protect the largest surviving population in the Leuser Ecosystem of Indonesia.

Around 1,500 Borneo pygmy elephants remain. The Borneo pygmy elephant is the smallest subspecies of Asian elephant, endemic to the island of Borneo. They are one of the least-studied elephants in the world.

Only 220 Indochinese tigers remain in the wild, with most of them in Thailand. The Indochinese tiger is a critically endangered population of tiger native to Southeast Asia, though it now only occurs in Thailand and Myanmar.
