Abstract: | Information contained on specimen labels of natural history collections is often the most reliable and available source of information to guide conservation decisions. When used for making IUCN Red List assessments, the inherent limitations associated with specimen information affect the assignment of Red List categories, and the case of the southern African plant Red Lists reflects this. Red List assessments that are based on specimen information can result in predictable outcomes, namely the tendency to assign the following categories: Data Deficient, Lower Risk-least concern, Vulnerable D2 or a threatened category using Criterion B. The reason for this is that specimen information satisfies distribution parameters of the IUCN system more readily than demographic parameters. |
