Conservation Efforts Sparks a Stunning Comeback for Wildlife
An ambitious rodent eradication program on Lord Howe Island, which spanned over two years and concluded in 2019, has resulted in a breathtaking revival of the island’s native species. The removal of invasive rats and mice, which decimated local wildlife, has allowed previously threatened or extinct-in-the-wild species to thrive again. Here are ten animals that have made an incredible comeback following the success of this conservation initiative.
1. Lord Howe Island Woodhen Population Triples After Rodent Removal
Once hovering near extinction, the Lord Howe Island woodhen is now a conservation success story. After the eradication program ended, their population rebounded dramatically, climbing from a mere 250 individuals to over 1,200. Without invasive rodents preying on their eggs and chicks, these flightless birds have spread across the island, thriving in areas they hadn’t inhabited in decades. The woodhen’s recovery is a powerful symbol of the program’s success.
2. Providence Petrels Reclaim Their Nesting Grounds
The Providence petrel, a seabird that relies heavily on Lord Howe Island for breeding, has flourished since the eradication effort. Before the program, rodent predation on their eggs kept breeding success dangerously low. With the invasive species removed, these nocturnal birds have seen their nesting success rates skyrocket. Their eerie nighttime calls now echo across the island, a haunting yet hopeful reminder of their resurgence.
3. Lord Howe Island Phasmid Poised for a Triumphant Return
The Lord Howe Island phasmid, also known as the “tree lobster,” was thought extinct for decades. Rediscovered on a remote islet, this giant stick insect is now being prepared for reintroduction to its native habitat on Lord Howe Island. The absence of rodents gives this species a fighting chance to reestablish itself, representing the potential for even the most fragile creatures to return.
4. Black-Winged Petrels Expand Their Nesting Colonies
Black-winged petrels, once driven from much of the island, have begun to reclaim their historic nesting areas. With rodents no longer preying on their eggs, these seabirds have experienced a population boom. Their return enhances the island’s biodiversity, contributing to a healthier and more balanced ecosystem.
5. Little Mountain Palm Seedlings Thrive Once Again
The Little Mountain Palm, a native plant species, suffered significant declines as rodents consumed its seeds. Since the program’s completion, this unique plant has shown signs of recovery, with seedling numbers increasing dramatically. This rejuvenation highlights how the removal of invasive species benefits not only animals but also the delicate flora that sustains them.
6. Lord Howe Island Gecko Bounces Back After Rodent Threat
Native geckos on Lord Howe Island faced intense predation from invasive rodents, leaving their populations dwindling. Post-eradication, these reptiles are thriving, with sightings becoming increasingly common. The geckos’ resurgence underscores how the removal of even one major threat can restore balance to an ecosystem.
7. Masked Boobies Rebuild Their Colonies Without Interference
Masked boobies, large and striking seabirds, have greatly benefited from the rodent eradication. Free from predation on their eggs and chicks, their colonies are growing steadily. These birds now have a safe environment to nest, which has strengthened their presence on the island.
8. Lord Howe Placostylus Snail Returns to Healthy Numbers
The Lord Howe Placostylus snail, a unique and slow-reproducing species, was heavily impacted by rodent predation. Since the eradication, its population has begun to recover, showing the resilience of even the most vulnerable creatures when given the chance.
9. Lord Howe Island Skink Recovers Its Habitat
Skinks, another native reptile species, are rebounding in the wake of the eradication program. With rodents no longer competing for resources or preying on their young, skinks are reclaiming their place in the island’s ecosystem. Their recovery is a testament to the wide-ranging benefits of eliminating invasive species.
10. Gnarled Mossy Cloud Forest Begins to Regenerate
The Gnarled Mossy Cloud Forest, a unique and fragile habitat on Lord Howe Island, suffered from rodent-induced degradation for years. Since the eradication’s completion, this ecosystem has started to regenerate. Native plants and invertebrates that had been in decline are making a comeback, restoring this extraordinary environment to its former glory.
