The reservoir and the surrounding woodlands are both Sites of Special Scientific Interest.[4] [5] The western end of the reservoir is the most vegetated. Fringing vegetation includes shore-weed (Littorella uniflora) and amphibious bistort (Persicaria amphibia), and such sedges as bottle sedge (Carex rostrata) and bladder sedge (Carex vesicaria), as well as taller stands of bulrush (Typha latifolia) and common spike-rush (Eleocharis palustris). Bladder sedge is rare in the county, only having been recorded at two other sites.[5] The reservoir is now home to a growing population of red kites.
The reservoir is visited by large numbers of migrating and overwintering wading birds and waterfowl. The most significant of these is the goosander, with up to 2% of the British population overwintering here. Others include wigeon, teal, pochard, shelduck, shoveler, ruddy duck, goldeneye, greylag goose, dunlin and green sandpiper, while mallard and tufted duck are present all year round, as are curlew, redshank and common sandpiper.[5]
