The Amboseli Ecosystem Trust (AET) was formed to coordinate and oversee the implementation of the Amboseli Ecosystem Management Plan (AEMP), and more broadly to promote coordination of stakeholder actions across this landscape. Formally established in 2009, AET is a trust that includes members from group ranches, the Kenya Wildlife Service, the county government of Kajiado, and a number of conservation organizations.
While AET was originally founded to coordinate the implementation of the AEMP, its identity and role has evolved, taking it in new directions beyond the ecosystem plan.
