Idechong resigned from his government post in 1994 to become the director of the Palau Conservation Society (PCS), Palau’s only environmental non-governmental organization. The organization’s mission is to preserve the region’s unique natural environment and build local community support and public awareness. PCS is also a proponent of sustainable economic development in the region.
In 1997, Idechong received a Pew Fellowship to pursue the application of traditional management practices in the waters of the far north of Palau.
