A multi-agency project has successfully eradicated invasive rats from the U.S. territory of Wake Atoll. The removal has led to a rapid resurgence of native seabirds, plants, and other wildlife, while also improving conditions for military personnel stationed there. The project was recently recognized by the U.S. Undersecretary of Agriculture.
Facts First
- Invasive rats have been eradicated from Wake Atoll by a collaboration including Island Conservation, the USDA, and the U.S. Air Force.
- 16 species of native nesting birds are reappearing and increasing, including a newly discovered Bonin Petrel colony.
- Populations of native geckos, skinks, and hermit crabs have increased, and thousands of new Pisonia tree seedlings are emerging.
- The removal has reduced disease risks and improved cleanliness for personnel at food-prep facilities, storage, and living quarters.
- The project received recognition from the U.S. Undersecretary of Agriculture.
What Happened
A multi-agency collaboration involving the nonprofit Island Conservation, the United States Department of Agriculture (USDA), and the United States Air Force Civil Engineering Squadron successfully eradicated invasive rats on Wake Atoll. Following the eradication, 16 species of nesting native birds are reappearing and increasing in number. A Bonin Petrel colony was discovered, marking the first documented nesting of this species on the atoll, and the Sooty Tern population experienced a record-breaking breeding season. Populations of geckos, skinks, spiders, moths, and hermit crabs have also increased, and thousands of new native Pisonia tree seedlings are emerging.
Why this Matters to You
This successful conservation effort demonstrates a model that could be applied to protect other vulnerable island ecosystems worldwide. For personnel stationed on Wake Atoll, the removal of rats has directly reduced the risk of disease transmission. Critical infrastructure on the island, including food-prep facilities, equipment storage, and living quarters, is now cleaner and more secure.
What's Next
The recovery of Wake Atoll's ecosystem is likely to continue as native species reclaim their habitat. Military personnel on the island have organized beach cleanups and other conservation activities, which may further support this ecological restoration. The project's recognition by the U.S. Undersecretary of Agriculture could help promote similar invasive species removal efforts elsewhere.
