The Indo-Pacific Conservation Alliance (IPCA) is dedicated to the study and conservation of the native ecosystems of the tropical Indo-Pacific region and support for traditional peoples in their stewardship of these globally significant natural resources. Our current field projects are located in Indonesia and New Guinea. Our main program is with the Asmat community of southwestern Papua, Indonesia, in the lowlands of Lorentz National Park, a UNESCO World Heritage Site, and the largest and most diverse protected area in the Asia-Pacific Region. Our conservation successes include halting destructive commercial logging and fishing operations. IPCA is based at the Bishop Museum in Honolulu, Hawaii. Rather than establish in-country offices, which is both expensive and unnecessary, we work with and through local partners to minimize overhead costs and put financial resources into the field where it is urgently needed. IPCA was formed in 1998 in collaborative association with scientists from the Smithsonian Institution, Bishop Museum, and other leading scientific and conservation organizations. Our projects are science-based and driven by our desire to work in authentic collaboration with indigenous communities, in-country scientists, local conservation groups, and other stakeholders. Our geographic focus is on the tropical Indo-Pacific region, a vast area that includes Indonesia, Melanesia, Micronesia, and Polynesia -- by far the most biologically and culturally diverse area of the planet.

At the Center for Biological Diversity, we believe that the welfare of human beings is deeply linked to nature — to the existence in our world of a vast diversity of wild animals and plants. Because diversity has intrinsic value, and because its loss impoverishes society, we work to secure a future for all species, great and small, hovering on the brink of extinction. We do so through science, law and creative media, with a focus on protecting the lands, waters and climate that species need to survive. We want those who come after us to inherit a world where the wild is still alive.
