Conservation
is all about geography; however, most of biodiversity is not
geo-referenced.As a consequence, the majority of the primary
specimen data that document biodiversity must be post factogeo-referenced
in order to capitalize on the current revolution in computer mapping and
spatial analysis brought about
through Geographical Information Systems (GIS) tools.In the course of taxonomic revision, we have systematically
assigned coordinates whenever possible to all historical specimens that originally lacked
coordinates.Reattributed primary
specimen data reside in TROPICOS
(http://www.tropicos.org/), the world’s largest botanical database, which is freely accessible from the Missouri
Botanical Garden through the Internet.Comprehensive, geo-referenced
specimen data for selected Malagasy species constitute the Madagascar Plant Conservation Database.
