Seabirds Reclaim Island Paradise From Invasive Weeds
5 Oct
Summary
- Over $1 million invested in South Islet restoration project.
- Invasive weeds threatened 35% of the island's vegetation.
- Seabirds nested in cleared areas within hours of weed removal.
An ecological restoration initiative on South Islet in Australia's Coral Sea Marine Park is successfully combating invasive weeds to protect vital seabird nesting grounds. The Australian Government has allocated more than $1 million to this project, which targets the removal of aggressive plant species that have encroached upon 35% of the island's vegetated area.
Expedition teams, including Parks Australia staff and Indigenous Rangers, have conducted intensive manual weed removal, clearing approximately 5 tonnes by hand. These efforts have yielded rapid positive results, with seabirds observed nesting in newly cleared areas within hours. Native species are being replanted to further restore the island's ecosystem.
South Islet, part of the Willis Islets, is a crucial breeding habitat for sooty terns, brown noddies, and wedge-tailed shearwaters. The restoration work not only safeguards these populations but also prevents the spread of invasive flora to nearby islands. This project is one of two ecological restoration efforts within the vast Coral Sea Marine Park, which spans nearly one million square kilometers off Queensland.
