[2] [6] The Green Status complements the Red List assessment but does not replace it: both assessments are performed by the IUCN for a given species and, with the exception of species extinct in the wild that would require reintroduction as a conservation measure and whose current Green Score is by definition 0%, one status does not determine ...
A Regional Red List may be created by any country or organisation by following the clear, repeatable protocol. The process is as follows: All information relevant to a species conservation status is collected, including species distribution, population trend information, habitat, ecology and life history information, threats to the species and conservation measures currently in place.

A visualization of the categories in the no-longer used "IUCN 1994 Categories & Criteria (version 2.3)", with conservation dependent (LR/cd) highlighted. The category was folded into the near threatened (NT) category in the 2001 revision, but some species which have not been re-evaluated retain the assessment.
