Jatun Sacha Great Wilderness is a California-based, international organization seeking to maintain the natural systems necessary to support life on Earth. Great Wilderness prioritizes conservation efforts based on the impact they will have on the protection and maintenance of global ecosystem services. Great Wilderness believes that the key to sustaining the web of life is the protection of critical, intact wilderness areas. The organization has streamlined the traditional work model for international organizations, by creating a core group based in the United States that implements international conservation efforts exclusively through established local partners. This model allows Great Wilderness to minimize costs and maximize productivity, while at the same time tapping into the broad-based local knowledge of grassroots efforts.
