Native invertebrates on Lord Howe Island are rebounding after the eradication of invasive rats and mice [1, 2].
This recovery is critical because the invasive rodents had decimated the island's native flora and fauna. The removal of these predators allows the island's unique ecosystem to restore its natural balance, and protect biodiversity [1, 2].
Lord Howe Island is a subtropical location in the Tasman Sea and is part of New South Wales, Australia [1, 2]. The ecosystem's recovery is most visible among the native cockroaches, beetles, and other insects that had previously struggled to survive under the pressure of rodent predation [1, 2].
Naturalists observing the shift have noted the rapid return of these species. Ian Hutton said, "That’s really something wonderful" [1].
The eradication effort was specifically designed to reverse the damage caused by non-native species. By removing the rats and mice, conservationists have created a safer environment for the island's endemic invertebrates to multiply and thrive once again [1, 2].
“Native invertebrates on Lord Howe Island are rebounding after the eradication of invasive rats and mice.”
The successful rebound of invertebrates on Lord Howe Island demonstrates the efficacy of island restoration through invasive species eradication. Because these insects play vital roles in pollination and nutrient cycling, their recovery likely signals a broader stabilization of the island's entire food web.
