Walung and Utwa are home to the Utwa-Walung Marine Park, a conservation area established by Madison Nena, a local ecologist who has won several awards, including the Seacology Prize in 1999.

In the late 1990s, Madison Nena successfully led a campaign to prevent property developers from building a tourist complex without adequate sewage facilities, and in its place he founded an eco-tourism initiative at Kosrae Village Resort.

He has also worked with island elders to revitalize historic methods of Kosraean house construction.
