Now, after one full year of rigorous monitoring\u2014including trail cameras, eDNA sampling, and field surveys\u2014the partners confirmed no invasive rodents remain on the island. This success marks a monumental step forward for conservation in Palau, the Micronesia region, and across the Pacific.<\/p>\n
Located due north of the eastern group of Indonesian islands, Palau is made up of 340 islands totaling 466 square miles of land area. Ulong is located in the western waters of the archipelago, and is considered one of the best diving spots on Earth.<\/p>\n
Ulong, where little human habitation exists, and which for all the world seems like the perfect tropical paradise, was nevertheless infested with rats brought there by ships. The doves were sitting ducks (or sitting doves) for the rats, which could get at their young and their eggs with ease.<\/p>\n
With the pressure of invasive species removed, however, signs of recovery in this unique ecosystem are already emerging. Island Conservation\u2019s monitoring team noticed a higher incidence of ground doves, including sightings of chicks at landing sites where they were never previously recorded.<\/p>\n
\u201cThe results are thrilling,\u201d shared Coral Wolf, Island Conservation\u2019s Impact Program Manager who conducted monitoring on the island over a three-year period, starting in 2022. \u201cWe\u2019re seeing and hearing recovery: since the program began, we\u2019ve recorded a significant increase in calls from brown noddies, white terns, and bridled terns. This increase occurred just one-year post-eradication\u2014who knows what recovery remains to be discovered!\u201d<\/p>\n

These early indicators of success can be expected to cascade into the surrounding marine ecosystem, which will benefit from repaired nutrient flows between land and sea.<\/p>\n
Acoustics data shows a dramatic increase in bird calls across the project site. Trail cameras also captured footage of Endangered Palau ground doves safely navigating the forest floor, fear from persecution by the rats.<\/p>\n
MORE OF ISLAND CONSERVATION\u2019S WORK:\u00a0<\/strong><\/p>\nAs well as the pristine beaches and reefs, Ulong is also home to precious artifacts of pre-colonial indigenous culture. Its ancient caves contain paintings and pictographs signifying beliefs and activities that far preceded colonialization. These treasured cultural sites are couched in an equally priceless, finely tuned ecosystem, home to many rare species.<\/p>\n
Tourists and their guides have also noticed the difference. Camping outings on Ulong Island have become more enjoyable, with fewer disruptions and a renewed sense of connection to the island\u2019s natural beauty and cultural history. To safeguard this progress, the partners implemented a robust biosecurity protocol to prevent reinvasion and protect the long-term conservation investment.<\/p>\n
\u201cConservation has always been central to Palau\u2019s identity, and here in Koror, we\u2019ve seen how it strengthens both our ecosystems and our way of life,\u201d a spokesman for the Koror State Government, under which Ulong is administered, said in a statement. \u201cThe restoration work on Ulong is a shining example of what\u2019s possible\u2014not just for our community, but for others across the Pacific who share our commitment to protecting island environments.\u201d<\/p>\n
Island Conservation, whose work GNN has reported on consistently<\/a> over the last we years, is currently analyzing monitoring data, including seabird point counts, camera trap footage, and stable isotope samples. These findings will be integrated into a broader island-ocean context in collaboration with Scripps Institution of Oceanography, with full initial results expected by early next year.<\/p>\n\u201cThis project shows the world what\u2019s possible when a partnership of culture, conservation and innovation unite.\u201d said Tommy Hall, Project Manager at Island Conservation. \u201cSeeing endangered species rebounding so quickly reminds us that nature is resilient; and with biosecurity securing the future, Ulong Island stands as a beacon of success for Pacific islands.\u201d<\/p>\n
