To help the Red List Authorities conduct all the necessary evaluations, the Red List Programme has adopted the use of RAMAS Red List, a software package developed by Applied Biomathematics, an ecological software company based in New York. This software applies the rules of the IUCN Red List Criteria to obtain an assessment, and also includes an algorithm for explicitly handling any data uncertainty (Akȧkaya and Ferson 2001). The Red List Programme Committee has approved the use of this software for obtaining Red List assessments, but the resulting RAMAS data files must be submitted along with any assessment done in this way to the Red List List Programme Office.
