The use of herbarium specimens in evaluating plant extinction risks: some considerations on Sicilian endemics

Herbarium specimens provide verifiable and citable evidence of the occurrence of plant taxa at a given place and time. Thus they caΩn be used to identify native ranges, and document which plants are occurring, and where, through time. They provide information on rare, extirpated, or extinct species that can no longer be found in nature. Furthermore, they can serve as a means of locating rare or possibly extinct species, recollecting in the area(s) reported on labels. Thus, herbarium specimens can be used as primary sources of data to have evidence-based extinction risk assessments. Each extinction risk assessments is an evidence-based hypothesis of the current level of extinction risk of a …
