IUCN Species Information Service

The IUCN Species Information Service (SIS) is the central database used by IUCN to store and manage species accounts and assessments for publication on the IUCN Red List.

Access to SIS is restricted to users who are involved in global or regional IUCN Red List assessment projects (e.g., IUCN SSC Specialist Group members, Red List Authority Coordinators, Red List Partners, IUCN Global Species Programme staff, IUCN Regional Office staff).

Registered users can access SIS online where they can prepare, edit and submit assessments to the IUCN Red List Unit in an appropriate format for publication on the IUCN Red List.

The following documents and tools are available to help users to find their way around SIS and begin using the system to create Red List assessments:
