The Ecological Significance of Bai Tu Long National Park
A Biodiversity Hotspot in Northern Vietnam
Bai Tu Long National Park stands as one of Vietnam’s most ecologically significant protected areas. The park’s biodiversity is truly remarkable, comprising:
- Marine Life: Home to over 110 fish species, 100 coral species, and numerous other marine organisms
