In 2017, Antigua and Barbuda removed over 6,000 rats and starving goats from Redonda; by 2019, vegetation rose over 20-fold and ground lizards eightfold

In 2024, Palau removed invasive rats from Ulong Island; one year later, fish biomass rose 183% and leaf nitrogen increased about 80% at one reef site

A new study from Ulong Island in Palau has found the first experimental evidence that restoring seabird populations by removing invasive rats can also help nearby coral reefs recover. Within a year, researchers recorded more seabirds, increased nutrient movement from land to sea and higher fish biomass, showing that island…
