Restoring vegetation and seabirds helps atolls adapt to rising seas
Researchers from Lancaster University published a study in Science Advances showing how removing rats and planting native trees can help low-lying atolls survive sea-level rise.
Invasive rats threaten island stability
An international team led by marine scientists at Lancaster University found that invasive species like rats harm seabird populations. These birds normally provide nutrients that build up soil on small tropical islands in the Indian and Pacific oceans. Without this natural process, the land cannot keep pace with rising water levels.
Native forests boost adaptation
The study suggests replacing abandoned coconut palm plantations with natural vegetation improves an island's ability to change. Healthy native forests allow these low-lying systems to adjust to new environmental conditions over time. This approach could help atolls withstand the projected sea-level increases expected by the end of the century.
