A classic fen wetland site in Cambridgeshire. Owned by the National Trust. First NT acquisition was 1899 (2 acres) and over 50 conveyances later the land area is 770 ha, of which 255 ha is SSSI/SAC and 170 ha is the high quality, ancient undrained sedge fen. In 1999, the NT launched its 'Wicken Fen Vision', an ambitious project to expand the nature reserve to 3500 ha over the following 100 years. From 1999 to 2014, 420 ha of arable land has been bought and is in the process of being restored for nature.
Recording here goes back into the 19th Century, with accounts of visits by entomologists in natural history publications/journals of the time, and with many specimens from Wicken Fen in museum collections. Two books and numerous papers and articles have been written about Wicken Fen.
The species records cover a very wide range of taxonomic groups, and most of them have been put on the NBN Gateway so that everyone can access the data.
