The seagrass meadows of South Malekula represent one of the most critical marine ecosystems within the Vanuatu archipelago. These extensive underwater fields provide a vital habitat and the primary food source for the region's vulnerable dugong population, often referred to as sea cows. In addition to dugongs, the meadows support numerous species of marine turtles, particularly the green sea turtle, which utilizes the area for foraging. The ecological stability of this region is intricately linked to the health of adjacent coral reefs and mangrove forests, which together form a natural defense against coastal erosion. Scientific research highlights that these seagrass areas are highly efficient at carbon sequestration, acting as significant 'blue carbon' sinks that help mitigate climate change. Local communities in Malekula are increasingly involved in community-based conservation efforts to reduce habitat destruction and protect the biodiversity that sustains local fisheries. Preserving these meadows is essential not only for marine life but also for the long-term environmental and economic resilience of the island's inhabitants.

📋 Practical info

📅

Best season

The best months to observe dugongs in the South Malekula seagrass meadows are from May to October. During this dry season the water is clearer and the animals come closer to shore.

🌅

Best time of day

Dugongs are most active early morning and late afternoon when they graze in the shallow seagrass beds. They usually avoid midday hours as the sun is too strong.

📜

Etiquette

Do not approach dugongs with motorboats as it frightens them. Do not dive or snorkel directly above them; keep a respectful distance instead.

🎒

What to bring

A good pair of binoculars or a camera with telephoto lens helps spot dugongs from the shore. Snorkeling gear is useful if you want to explore the seagrass meadows up close.

🧭

Getting there

The seagrass meadows lie off the south coast of Malekula, reachable by boat from the town of Lamap. Local fishermen offer trips to the best observation areas.

What to expect

Dugongs are shy animals that rarely surface. Plan for multiple attempts and remain quiet - a sighting is a special stroke of luck.
