Natural History Collections
Primary data that document the “what,”
“where,” and “when” of Life on Earth
Natural history collections constitute the primary data that document the “what,” “where,” and “when” of Life on Earth and therefore have a critical role to play in the conservation and sustainable use of biodiversity.  Principal knowledge of biological diversity emanates from the study of natural history collections by taxonomists.  Plant taxonomists utilize herbarium specimens to erect taxonomic frameworks within which species are defined, circumscribed, and delimited from related species.  In addition to portraying the limits of variability of individual species, those herbarium specimens deemed representative of a given species also constitute the primary occurrence data that collectively depict the verifiable (i.e., vouchered) geographical range of the species.
