About OIKONOS-ECOSYSTEM KNOWLEDGE

Oikonos‑Ecosystem Knowledge is a registered 501(c)(3) conservation science organization based in Kailua, Hawaiʻi that runs science, education, and community-engagement programs to protect seabirds, saline lakes, island ecosystems, and other threatened habitats across the Americas. The organization’s EIN (03-0385067) is confirmed in its publicly posted Form 990 and impact reporting. In recent years (notably 2023–2024) Oikonos has carried out international field research, community education on Isla Mocha (Chile), seabird bycatch studies with NOAA partners, and technology-enabled tracking projects to inform management and policy.

Notable achievements

Nanotagging Wilson’s Phalaropes (2023)

Tracked the migration of 25 Wilson’s Phalaropes with nanotags in 2023—the first time this species was tracked with this technology—providing new data used to inform a proposal to consider listing the species under U.S. endangered species processes.

Federal Award for Seabird Stewardship

Recognized with the U.S. Presidential Migratory Bird Federal Stewardship Award for long-standing collaboration with NOAA on seabird bycatch research and solutions; Oikonos’ work has supported management changes to reduce bycatch in Hawaii-based fisheries.

Community education and workforce training

Sustained on-the-ground education programs (e.g., Isla Mocha school and kindergarten programs engaging ~70 children), delivered sterilization and responsible-pet campaigns (noted 50% sterilization on Isla Mocha), and trained more than 70 early-career conservationists in seabird monitoring and restoration techniques (program activity documented in 2023).
