These six areas all have fen or swamp with large numbers of Desmoulin's whorl snail, which is listed in the British Red Data Book as it is a nationally rare and declining species. One of the areas, Eddington Marsh, also has unimproved species-rich grassland with several nationally scarce invertebrates, such as the flies Pherbellia griseola, Psacadina verbekei, Platypalpus niger and Oxycera morrisi.[5]
