Mining Permits Overlap Indonesian Marine Refuge for Humphead
A protected bay in Indonesia, home to a critically depleted population of humphead wrasse, faces pressure from overlapping mining permits.
A marine protected area in Indonesia's Southeast Sulawesi province is home to a critically depleted population of humphead wrasse. The species' presence helped the area gain its protected status, but mining permits overlap parts of the conservation zone and line its coast.
A 2024 government survey found just 22 humphead wrasse across 10 sampling stations in the Moramo Bay local marine protected area. It recorded no fish at three sites where the species was still observed in 2018.
Mounting Pressures on a Critical Habitat
Officials and researchers say the bay's coral reefs face mounting pressure from sedimentation, pollution, and vessel activity. Sasanti Retno Suharti, a coral reef fish ecology researcher, told Mongabay Indonesia that in polluted areas, the humphead wrasse "will definitely disappear." She warned its absence could allow crown-of-thorns starfish to proliferate and damage the coral ecosystem.
The protected area was formally designated in 2021 to safeguard coral reefs, seagrass, mangroves, and protected fish like the humphead wrasse. The waters lie within the Coral Triangle, a region famed for its marine biodiversity.
Coral Decline and Mining Proximity
A separate 2024 study led by conservation analyst Anung Wijaya found a 12.6% decline in coral cover between 2018 and 2024 near Lara Island, where the humphead wrasse is now virtually extinct. The study warned that ongoing limestone mining in a mainland village less than 2 kilometers away could affect reefs through sedimentation.
"Reclamation activities to build infrastructure supporting mining operations, such as special terminals, as well as the transportation of processed mining materials, can contribute to increased water turbidity in the surrounding area," Anung wrote. However, he stated that no study has established a direct link between mining and the wrasse's decline.
Permits Predating Protection
At least 12 mining permit areas for quarry materials are located along the Moramo Bay coast. Three companies hold active production operation permits, with two of these permits extending into the sea and overlapping the conservation area.
| Company | Permit Type | Permit Area | Permit Validity |
|---|---|---|---|
| PT Citra Khusuma Sultra (CKS) | Production Operation | 122 hectares | Through 2030 |
| PT Ramadhan Moramo Raya (RMR) | Production Operation | 11 hectares | Through 2030 |
| PT Hoffmen Energi Perkasa (HEP) | Production Operation | 11 hectares | 2026 to 2031 |
Muhammad Hasbullah Idris, a local energy agency official, said the permits predated the conservation area's designation and were issued after the regency government declared the areas suitable for mining. He claimed a visit in February found the water was still clear.
Calls for Permit Review
Andi Rahman, of the Indonesian Forum for the Environment, criticized the extension of mining permits that overlap the protected area. He questioned the agency's claim of no pollution, saying the assessment lacked standardized indicators.
He argued the government should have reviewed the permits after the local spatial plan was revised. "If the reason is that the permits had already been issued, fine," Andi said. "But when the spatial plan changes, that should be grounds for evaluating and revoking the mining permits." Jupri, a local ecosystem manager, said he had reported potential mining threats to authorities, expressing uncertainty about the protected area's future if operations expand.
