Wicken Fen complete natural history goes omline [sic]
Wicken Fen set for wildlife first on the web
More than 7,400 species
The archive includes records of more than 7,400 different species over a 180 year period and this is the most comprehensive collection of natural history information for a single site. Developed by the National Biodiversity Network, the archive will enable wildlife enthusiasts to access maps and records about Wicken Fen at the click of a mouse. …
The most diverse group of species is not the plants or birds, but the invertebrates and especially the insects. Three groups of insects each have over 1000 species, the flies (1,893 species), the beetles (1,527 species) and the moths (1,083 species).
These three groups alone make up more than 56 per cent of all the species found at Wicken Fen. When all of the records from Wicken Fen have been added, and once classifications are complete, this will take the total number of species found here to more than 8,100 species.
Stuart Warrington added: “Just a short distance from Cambridge, Wicken Fen has a prodigious list of rare species from plants such as the Great Fen Sedge, Fen Violet and Whorled Water-Milfoil to birds including the Marsh Harrier and Cuckoo. Perhaps even more impressive is that there are over 600 insect species at Wicken that are listed as nationally endangered, rare or scarce in the UK Red Data Books.”
