The OSG is an IUCN SSC expert network of +250 members from 56 countries in the world. We take pride in being a strong and inclusive community, demonstrating  a long-term commitment to otter conservation in its broadest sense.

Please note that the OSG will update its operational structure for the 2026–2029 IUCN quadrennium – all updates will be posted on this page.

Find the OSG on the SSC One Stop Shop platform, a resource site for the entire SSC Network (only for members).
