In 2000, a non-profit organisation by the name of Gili Eco Trust was established to help protect the coral reefs surrounding the islands and improve environmental education. It originated as a co-operation between influential members of the local community (Satgas) and the dive shops on Gili Trawangan and was initiated by the owners of Manta Dive. Many projects have since been organised to protect and restore coral reefs, improve waste management, struggle against erosion, treat animals, raise awareness and educate. This was needed as damage had occurred due to a particularly warm El Niño and unsustainable local fishing methods.
