EcoPort is a database, not just a website, devoted to inter-disciplinary integration of information to manage biodiversity. The programme operates under the auspices of the University of Florida, FAO and the National Museum of Natural History of the Smithsonian Institution. It offers a framework and tool chest of procedures to enable anyone who wishes to teach and learn about biodiversity, to share their knowledge by using EcoPort as a consilience engine. EcoPort contains, amongst others, taxonomic keys to identify living organisms, information on them, pictures of them, an indication of their interaction with other living organisms, and literature references.
Identification of plant specimens:Dried and pressed plant specimens can be sent to the National Biodiversity Institute for identification. Clearly print on the package: "Dried specimens for identification". Address all correspondence to The Director, SANBI, Private Bag X101, Pretoria 0001.
