Red List Assessment Tools for Members

The primary role of the Marine Turtle Specialist Group is to conduct regular Red List Assessments of marine turtles. In an effort to improve understanding and participation in the Red List Assessment process by all MTSG members, the following tools and resources are provided:

  1. A tool built in Excel that provides a rough indication of the likely Red List categories for a sea turtle Regional Management Unit (RMU). A maximum of ten types of data are needed for this simple exercise. With this tool you can familiarize yourself with the types of data and the possible outcomes of a Red List Assessment, and tentatively provide your own Red List Assessment for your RMU(s). The excel file also includes a sheet with an example for calculating past, present, and future values from individual sites.
  2. A one page summary of the Red List Criteria.
  3. The complete guidelines for Red List Assessments.
