Leuser Ecosystem Action Fund

The Leuser Ecosystem is 6.5 million acres of rainforest on the Indonesian island of Sumatra, and the last place on earth where orangutans, rhinos, elephants, and tigers still live together in the wild. The pristine lowland jungles, lush peat swamps, and cloud shrouded mountain forests are one of the last remaining intact rainforests in all of Indonesia, serving as a carbon storage powerhouse and the source of drinking water and agricultural livelihood for millions of people. 

But the Leuser Ecosystem is under siege. Its vast forests are being relentlessly destroyed for quick profit, pushing its iconic wildlife species to the brink of extinction. Thankfully, an effective network of grassroots activists across the region has emerged. Acting on the ground, with communities, through local political channels, and at the international level, these brave and visionary conservation champions are taking a stand to protect this precious environment from the many threats it faces.

LDF has partnered with several committed philanthropists and the Sumatran Orangutan Society to create the Leuser Ecosystem Action Fund (LEAF). The fund will raise new resources to support the effort and provide strategic, targeted, and flexible support to these guardians of Leuser, allowing them to scale up their work and focus on the long-term impact of their programs. Supporting this incredible group of dedicated organizations offers the best hope for protecting this irreplaceable ecosystem, the iconic species that live there, and the countless lives and livelihoods which depend on the survival and protection of Leuser. 

Through collaborative partnerships, we support innovative projects that protect vulnerable wildlife from extinction, while restoring balance to threatened ecosystems and communities. Our work is divided into six main program areas – Wildlands Conservation, Oceans Conservation, Climate Change, Indigenous Rights, Transforming California, and Innovative Solutions.
