   Scientists identify two pristine Marshall Islands atolls as among Earth's last untouched marine ecosystems

   Researchers have confirmed that Bikar and Bokak atolls in the Marshall Islands host coral reefs and fish populations virtually unaltered by human activity. Surveys documented exceptionally high coral cover, abundant apex predators including grey reef sharks, and Napoleon wrasse densities far exceeding regional baselines. The findings, published after expeditions by the Pristine Seas project and local partners, position these remote atolls as global benchmarks for intact reef ecosystems. Scientists emphasize their value as reference sites for restoration and climate resilience studies.

   Why it matters

   Most coral reefs worldwide have suffered degradation from overfishing, pollution, and warming seas, leaving few baselines for what healthy systems look like. The Marshall Islands' extreme remoteness and limited human presence have preserved Bikar and Bokak in a near-prehuman state. Their intact food webs and high biomass offer rare insight into natural reef function and recovery potential. Protecting such sites is urgent as climate impacts reach even isolated regions.

   What is confirmed

   • Bikar and Bokak atolls in the Marshall Islands host coral reefs with exceptionally high coral cover and intact fish communities.
   • Surveys recorded abundant apex predators including grey reef sharks and Napoleon wrasse at densities far above regional averages.
   • The Pristine Seas project conducted expeditions with local partners to document these ecosystems.
   • Scientists describe the atolls as among the last wild and healthy marine ecosystems untouched by humans.

   Still unconfirmed

   • The atolls may receive formal marine protected area designation following these findings.

   What to watch next

   • Marshall Islands government decision on formal protection status for Bikar and Bokak
   • Long-term monitoring data on climate resilience of these reefs compared to degraded sites
   • Potential expansion of Pristine Seas surveys to other remote Pacific atolls
