Seabird Populations Increase on Islands Following Invasive Species Eradication
Several islands have seen significant seabird population recoveries following the eradication of invasive species such as rats, goats, and cats. On D'Arros Island, Seychelles, wedge-tailed shearwater pairs increased from about 250 in 2009 to nearly 2,800 by 2016. Similarly, Zannone Island in Italy saw Scopoli's shearwater pairs nearly triple after rat removal in 2007. Klein Curaçao's seabird numbers rose from 140 pairs in 2002 to around 650 by 2022 after removing goats and cats. Surprise Island in New Caledonia also experienced two- to tenfold growth in seabird populations post-rat eradication. These cases highlight invasive species removal as an effective conservation strategy, though ongoing threats like human disturbance remain concerns.
