Founded in 1999, the Amazon Conservation Association (ACA) works to conserve the biological diversity of the Amazon. We work to protect biodiversity by studying ecosystems and developing innovative conservation tools to protect land in the region while supporting the livelihoods of local communities. We work by forging ties with governments, nonprofits and people who depend on the rainforests for their livelihood, with the goal of saving rare species and habitats and learning from the land. Scientific research guides our approach, which strives for concrete, measurable achievements. ACA has offices in Washington, DC.
