Sumatra’s rainforests are among the most biodiverse places on Earth, home to critically endangered species like the Sumatran orangutan, tiger, elephant, and rhinoceros.

Eco-tourism is emerging as a powerful force in protecting the forests they call home, and the communities surrounding them—when done ethically.

In the heart of Sumatra’s lush rainforests, where there are estimated to be fewer than 400 Sumatran tigers remaining, hands-on conservation work is an urgent necessity.

Habitat destruction, poaching, and human-wildlife conflict have pushed these majestic big cats to the brink of extinction.

But this hands-on initiative is protecting local livelihoods and helping prevent conflict with wild tigers.

Hidden within the heart of Sumatra, Indonesia, lies one of the most extraordinary and irreplaceable landscapes on Earth—the Leuser Ecosystem.

Covering 2.6 million hectares, this vast rainforest is the only place left where Sumatran orangutans, tigers, elephants, and rhinoceroses coexist in the wild.
