A local initiative was set up to help the Green turtle and Hawksbill turtle population of Gili Trawangan. Turtle egg poachers are paid for their find and the eggs are re-buried and kept under surveillance. Upon hatching the baby green and hawksbill turtles are placed in a tank and allowed to grow until they are approximately 6 months old. At this stage they are mature enough to fend for themselves and are lovingly released into the sea.
The project still relies purely on donations by locals and tourists with support increasing every year.

In 2004 began a project to encourage the re-growth of coral using a method called the Bio-rock process. The system involves a safe low-voltage current that is applied though the seawater. This electric current attracts minerals in seawater to a man made steel structure where these minerals grow into limestone very similar to coral reefs.
In 2006, after the success of the original project, all dive operators on the island joined together to construct more Bio-Rock structures. At this stage up to 14 Bio-Rock structures can be found in shallow waters (5-8m) at points in front of each dive shop.

The Gili Eco Trust was set up to protect coral reefs around the island against destructive fishing practices. A one-time donation of Rp. 40,000 is requested of each diver by the dive centers on Gili Trawangan to pay fisherman to stop using harmful fishing methods that damage the reefs. Funds from these donations are also used for beach cleaning and rubbish management.
Line fishing, spear fishing and surface nets are permitted as these methods are not harmful to the reefs and the eco-system.
