Coral Reefs of Alega Bay
Vibrant underwater ecosystems teeming with life, protecting our coastline and sustaining Samoan marine traditions for generations.
Living Underwater Gardens
The coral reefs of Alega Bay represent some of the most pristine and biodiverse reef systems in American Samoa, covering over 25 acres of protected marine habitat.
These living ecosystems provide essential services including coastal protection, fish habitat, and cultural significance for traditional Samoan fishing practices.
Our comprehensive reef conservation program combines scientific research, community engagement, and active restoration to ensure these vital ecosystems thrive for future generations.
