When engineers dredged a shipping channel through the Tanjong Pelumpong sand spit in the 1970s to build Muara Port, they severed the spit from the mainland and left behind a 64-hectare island that nobody had planned. The channel was armored with concrete and boulders, groynes were installed to prevent silting, and the port went about its business. But the island refused to be an afterthought. Its eastern edge began creeping outward at 30 meters per year, building itself grain by grain. Corals colonized the groynes. Seagrass meadows spread across the shallows. Within four decades, Pelumpong Island had transformed from an engineering byproduct into one of the richest marine habitats in Brunei Bay.

Pelumpong Island: Brunei's Accidental Eden: A Reef That Shouldn't Exist

Sedimentation rates here average over 70 milligrams per square centimeter per day -- levels that would smother most reef systems. Yet coral cover on the southeast-facing groyne reaches a remarkable 59.8 percent, with 34 identi...

Seagrass meadows carpet the shallows around the island, forming a quiet cafeteria for one of Southeast Asia's most elusive marine mammals. The endangered dugong -- sometimes called the sea cow for its placid, herbivorous temp...

A 122-hectare offshore fish cage culture farm dominates the waters around the island, producing seabass, pompano, red snapper, and grouper in quantities that make it a cornerstone of Brunei's fisheries industry. In 2018, the farm yielded 315...

Pelumpong Island: Brunei's Accidental Eden: Spit, Island, Strategic Asset

The channel between the former spit and neighboring Pulau Muara Besar was originally cut to 9 meters during Muara Port's construction, then deepened to 12.5 meters in 2000 as plans advanced to develop PMB into a superconta...
