Edition 001 reported on the nickel-mining threat to Raja Ampat, the marine protected area in eastern Indonesia that has been called the global epicentre of coral biodiversity. The piece focused on what was at risk. This piece reports on what has been recovered.
Misool is the southernmost of the four main islands that give Raja Ampat its name (raja ampat is Indonesian for “four kings”). In 2005, a small private foundation established what was, at the time, the only no-take marine reserve in the region: 1,220 square kilometres of waters around Misool placed off limits to all fishing and harvesting. The reserve was negotiated with the local Misool community and incorporated the community's traditional sasi system of seasonal closures, extending and formalising it into permanent protection.
In 2007 the Misool Foundation, the operator of the reserve, commissioned baseline biological surveys. The surveys recorded what 30 years of fishing pressure had produced: a depleted but not destroyed ecosystem, with coral cover intact in many areas but reef-fish biomass substantially below historical levels. The surveys have been repeated periodically since.
The 2023 survey, the most recent published, recorded reef-fish biomass within the reserve at approximately 250% of the 2007 baseline. The number is not a typo. Across the same period, biomass in comparable unprotected waters in the region declined or remained flat. Shark populations within the reserve, which had been nearly absent in 2007, have recovered to densities comparable to those documented at remote reference sites with no significant fishing history. The mantas that had become rare have returned in numbers sufficient to support the dive-tourism economy that funds the foundation's conservation work.
The Misool story is sometimes presented as a small-scale conservation success, distinct from the larger structural problems facing marine ecosystems globally. The framing is incomplete. The lesson Misool actually demonstrates is what marine ecosystems are capable of when fishing pressure is removed: not gradual decline, not slow stabilisation, but in many cases substantial recovery within human-relevant timescales. The biomass numbers are not unique to Misool; comparable recoveries have been documented at the Apo Reef in the Philippines, at several locations in Palau, and at the long-protected waters around Cocos Island, Costa Rica.
What this means structurally is that the global marine-extraction picture is not a story of inevitable decline. It is a story of fishing pressure that, where it has been removed, has produced systems that recover. The barrier is not biological. It is political — the willingness or unwillingness of jurisdictions to remove pressure on enough waters for long enough to allow recovery. Misool removed pressure on 1,220 square kilometres for two decades. The recovery is what happened next.
The nickel-mining threat reported in Edition 001 puts this work at risk. The Misool reserve sits within the Raja Ampat regional marine protected area, parts of which the Indonesian government has indicated may be reopened for mining operations. The foundation continues to operate. The recovery continues. The political pressure remains.
