Facts about Vanuatu Reefs
- 10
Spawning aggregations of grouper and snapper species at Vanuatu's reefs concentrate in predictable locations during specific lunar phases, making them vulnerable to overfishing if harvest timing aligns with reproductive events.
- 09
Mangrove forests adjacent to Vanuatu's reefs sequester carbon at rates of 3.7 metric tons per hectare annually, providing critical climate regulation alongside coral ecosystem services.
- 08
Vanuatu's reefs support at least 350 coral species, representing approximately 40% of all coral diversity found throughout the entire Indo-Pacific region.
- 07
Vanuatu's reef systems span approximately 4,400 square kilometers of coral coverage across the archipelago's 83 islands, forming a crucial marine biodiversity hotspot.
- 06
Over 70% of Vanuatu's population depends directly on reef ecosystems for food security and livelihoods through subsistence fishing practices.
- 05
Between 2016 and 2020, Vanuatu's reefs experienced a significant coral bleaching event affecting approximately 50% of surveyed coral colonies due to elevated sea temperatures.
- 04
Vanuatu's reefs provide direct economic benefits worth approximately 140 million USD annually through tourism, fishing, and coastal protection services.
- 03
Approximately 65% of Vanuatu's reefs face threats from crown-of-thorns starfish outbreaks, which have periodically devastated coral communities since the 1960s.
- 02
Vanuatu's coral reefs experience sea surface temperatures averaging 28-29°C annually, supporting thermophilic species adapted to warm tropical waters.
- 01
The Vanuatu Reefs contain over 800 species of reef fish, making them among the most biodiverse coral ecosystems in the South Pacific region.
