Marshall Islands Celebrate Rat Eradication Success on Bikar Atoll and Jemo Islet

In a significant conservation victory, invasive rats have been successfully eradicated from Bikar Atoll and Jemo Islet in the Marshall Islands. The achievement, a result of a collaborative effort by several local and international organizations, has brought joy to traditional leaders and the people of Likiep, Utrik, and the Marshall Islands government.

The rats, which had overrun the islands, caused ecological chaos. They devoured native vegetation and preyed on baby crabs, eggs, and turtle hatchlings, decimating local wildlife populations. An eradication program was undertaken by Island Conservation, the Marshall Islands' Marine Resources Authority, and the Ministry of Natural Resources and Commerce. In July 2024, rat bait was dropped by drone, targeting rats with little effect on other species. Following the program, rodents were successfully removed from both islands.

The successful eradication project serves as a blueprint for other islands in the Marshall Islands and beyond. With the rats gone, seabird populations have soared, and native flora and fauna, including Pisonia grandis trees, have begun to rebound. The restoration of the ecosystem helps to connect the deep ocean, land, and reef through natural processes. The goal is to keep these islands rat-free, with no plans to reintroduce new species or modify the habitat.

The eradication of rats from Bikar Atoll and Jemo Islet marks a significant step in the preservation of the Marshall Islands' unique ecosystems. The success of this project offers hope for similar initiatives across the region and beyond.
