Eight decades after Wake Atoll became synonymous with wartime conflict, the remote Pacific territory has emerged victorious from another battle—this time against an invasive species threatening its fragile ecosystem. A collaborative conservation initiative has successfully eradicated rats from the unincorporated United States territory, triggering a cascade of ecological improvements that extend from seabird populations to the daily lives of military personnel stationed there.
The multi-agency effort, coordinated by nonprofit Island Conservation alongside the United States Department of Agriculture (USDA) and the United States Air Force Civil Engineering Squadron, has restored the atoll's environment to its endemic state. The achievement represents a significant victory against a species that has degraded island ecosystems throughout the Pacific through rapid breeding and opportunistic behavior.
"We're astonished—and thrilled—at the results of this work," said Tommy Hall, Project Manager at Island Conservation. Hall and the project recently earned recognition from the US Undersecretary of Agriculture for its success, which officials have highlighted as a model for collaborative conservation efforts. "These benefits will strengthen the island's ecosystem, but they'll also help Wake's inhabitants thrive, now that we've removed the threat to important infrastructure, making food and water safe from contamination."
The ecological response has been swift and dramatic. Sixteen species of nesting native birds are reappearing and increasing in number without invasive rodents devouring their eggs and young. A newly discovered Bonin Petrel colony—known as Nunulu in Hawaiian—marks the first documented nesting of this species on Wake Atoll. The atoll's globally significant population of Sooty Terns enjoyed a record-breaking breeding season following the eradication.
Other native seabirds are demonstrating early signs of recovery as well. Laysan albatross, wedge-tailed and Christmas shearwater, black-footed albatross, red-footed booby, and red-tailed tropicbird populations are all showing increased nesting activity and improved reproductive success. The benefits extend beyond avian species—populations of geckos, skinks, spiders, moths, and hermit crabs have surged, serving as indicators of a healthy, recovering ecosystem.
The island's vegetation is rebounding with particular vigor. Thousands of new native Pisonia tree seedlings are emerging in areas where none were previously observed. "The rats consumed virtually all of the Pisonia seed—I had never seen a seedling before the rat eradication. Now there are hundreds, if not thousands, of Pisonia seedlings," said John Gilardi, an ornithologist working with Island Conservation.
The human dimension of this conservation success extends to the military personnel stationed on Wake Atoll. With the island free of invasive rats, the risk of disease transmission has been significantly reduced. Critical infrastructure—including food-prep facilities, equipment storage, and living quarters—is now cleaner, safer, and more secure. The visible transformation has inspired several individuals among the military personnel to organize beach cleanups and other conservation activities.
Island Conservation has established itself as one of the most effective conservation organizations globally. The organization's teams have successfully removed invasive species on approximately 70 islands worldwide, permitting hundreds of native species to return to habitats that often represent their only remaining refuge on Earth. The Wake Atoll project demonstrates how sustained conservation action can produce rapid and far-reaching ecosystem improvements, offering a blueprint for similar efforts on vulnerable island territories throughout the Pacific and beyond.
