2017 - 2020


Membership of SSC is conferred by becoming a member of one of the Commission’s sub-groups (e.g. Steering Committee, Sub-Committees, Specialist Groups, Red List Authorities, Task Forces, Working Groups). Membership of these groupings is voluntary and by invitation. SSC seeks to engage cutting-edge experts in all disciplines relevant to the conservation and management of biodiversity. It engages such people with due regard for diversity, be it in terms of gender, age, culture, language, nationality and expertise. By design, SSC members do not hold a common view on most conservation-related issues. Rather, SSC cherishes its diversity and fosters open, respectful, rigorous and evidence-based debate among its members”. - IUCN SSC 2017-2020 Mandate.
