GoKawiilStudy: restoring seabirds and native plants helps atolls keep pace with sea-level rise
A study published in Science Advances by researchers led by Nick Graham of Lancaster University examined 28 atoll islands in the Pacific and Indian oceans, finding that intact ecosystems of seabirds, native vegetation and reef organisms help the islands grow and adapt to rising seas. Seabird guano fertilizes plants and coral, parrotfish convert dead coral into sand, and plant roots stabilize sediment, together reinforcing island growth. The researchers say eradicating invasive rats and replacing coconut plantations with native forest could give islands a better chance of keeping pace with sea-level rise expected by century's end under roughly 2°C of warming.
GoKawiil's interpretation of the reporting above, not reported fact.
The findings suggest that ecological restoration, not just engineering, could be a practical tool for protecting low-lying island nations from climate-driven sea-level rise. This adds to a broader body of evidence, cited by the researchers, that restoring wetlands and forests can buffer other climate impacts such as flooding, drought and fire. If applied widely, such rewilding efforts could also support carbon storage, though the actual effectiveness of rat eradication and reforestation at scale remains to be demonstrated.
- Study of 28 Pacific and Indian Ocean atolls shows healthy ecosystems help islands grow and adapt to sea-level rise
- Seabirds, native plants and reef organisms work together to build sand and stabilize islands
- Researchers suggest eradicating rats and restoring native forests could improve islands' odds against 2°C-level sea-rise scenarios
