Palmyra’s thriving reef faces a new protection fight
A visit to the remote Pacific island ecosystem losing protections
Palmyra shows what strong conservation can restore, while proposed commercial fishing threatens to test how much protection these ecosystems need.
- 1Palmyra Atoll’s recovering reefs and abundant wildlife reveal how interconnected habitats can rebound after invasive species removal.
- 2Proposed commercial fishing in protected Pacific waters pits regulated use against evidence that full protection strengthens vulnerable ecosystems.
- 3Native Hawaiian stewardship frames marine monuments as cultural and spiritual places, not merely conservation zones.

Sommer describes hermit crabs gathering across Palmyra’s beach, an intimate scene that captures the atoll’s unusual abundance and wildness.
The brief
Lauren Sommer reports from Palmyra Atoll, where strict biosecurity protects a small research community and one of the Pacific’s richest remaining ecosystems.
The atoll’s seabirds, sharks, fish, forests, guano, and coral reefs operate as one nutrient cycle; removing invasive rats shows damaged habitats can recover.
That recovery sharpens the dispute over proposals to reopen parts of Pacific marine monuments to commercial fishing, even as warming oceans pressure reefs.
Fishing interests argue regulated harvest can coexist with conservation, while scientists point to ecological impacts and the potential benefits of spillover from fully protected waters.
The episode closes on Native Hawaiian stewardship and a beach crowded with hermit crabs, a vivid reminder of what these protected places hold.
