Sonsorol State, in the remote Southwest Islands of Palau, is a place of deep cultural heritage and ecological significance. With four islands, just 40 residents, and a rich history of traditional leadership, this island community has invited Island Conservation to provide support in forging a bold path toward restoration. 

In partnership with the elected Sonsorol State Government and the councils of each island, Island Conservation is preparing to launch a transformative project in late 2025. Together, we’re pursuing a shared vision: a thriving, biodiverse Sonsorol free from invasive predators. 

Though small in size, Sonsorol’s islands are steeped in legend and resilience. Oral histories trace the first settlers to the islands of Yap, with tales of clever contests for land ownership and enduring kinship ties with neighboring Hatohobei. Over centuries, the Sonsorolese developed sustainable practices to thrive on limited resources—smoking fish, preserving breadfruit, and crafting earth ovens to make food last. Their language and customs remain distinct from mainland Palau, echoing connections to Outer Island Yap and Chuuk. Despite colonial upheavals and typhoons that once washed out entire islands, the people of Sonsorol have preserved their cultural identity and continue to steward their islands with wisdom and pride. 

Now, they take aim at invasive species like damaging, non-native rats and Coconut Rhinoceros Beetles, which have devastated local ecosystems. Fanna Island, once lush with coconut palms, now has none. Invasive rats threaten food security, spread disease, and decimate seabird populations—species that are vital connectors between land and sea. Their guano nourishes soil and reefs, supporting fish populations and coral resilience. 

Island Conservation and our partners, including SPREP and PRISMSS, aims to restore the natural balance by removing invasive rodents and providing assistance with beetle control. These seemingly small interventions can make an outsized impact for communities who aim to holistically improve the health of their ecosystems. Sonsorol’s traditional leaders and government are guiding this effort, ensuring it reflects local values and priorities.
