DISTRIBUTION MAPS FOR CLADOCERA IN BRITAIN AND IRELAND

Last Updated January 2017 with 938 extra records and new maps for Bosmina longispina
In total 16927 records are represented on the maps below.
All maps available as a 50 page Atlas, now version 3B- March 2017 ..... Download here 5.13mb For a map of all atlas sites .... Click Here

          The table below shows the 92 species on the updated checklist for the British Isles published by the Cladocera Interest Group in 2011. 90 distribution maps have been created by combining recent records made by group members with data from literature sources and several thousand records from the database of the Biological Records Centre. We are grateful to Dr Helen Roy of the Centre for Ecology & Hydrology for permission to use the BRC data, a great deal of which comes from the first Waterflea Recording Scheme run by John Hearne. Species for which we hold no records are noted as such, but obviously they have no map. (Note *** Chydorus gibbus has now been listed here as "Species inquirenda" for further details see John Bratton's article in Newsletter 5 p10.)

          There were rumours of a provisional atlas of waterfleas from John Hearne's time but this was apparently not widely available and no copy has been found. The maps below will hopefully fulfil the function of a provisional atlas in a modern format having the advantage that the individual maps can be quickly updated when new records arrive, although it should be born in mind that at present the number of records is not as large as we would like. Each map is available in two formats.

          To the right of each species name are two links to a GIF or WMF file. The green GIF link will produce a distribution map in a pop up browser window which can be enlarged to suit the viewer. This image is best used for viewing on screen although it can also be downloaded. The second link in blue will allow you to download the map as a Windows Metafile. WMF graphics are useful because in most Windows software like Word or Excel the map can be enlarged without losing detail or causing pixelation.

          Please acknowledge the Cladocera Interest Group if you download maps for use in your own papers or other publications.
