Support our team in protecting and restoring the Leuser Ecosystem—the last place on Earth where Sumatran orangutans, rhinos, elephants, and tigers coexist in the wild. All four species are now critically endangered, but together we can turn the tide.

Please support us through our partners, The Orangutan Project (TOP) and Wildlife Asia (WA), who manage our donations via this website. TOP President Leif Cocks and WA Executive Director Clare Campbell serve on the advisory board for HAkA.
