Annex I habitats that are a primary reason for selection of this site
|91E0 Alluvial forests with Alnus glutinosa and Fraxinus excelsior (Alno-Padion, Alnion incanae, Salicion albae) * Priority feature|
|These, the largest fragments of alder-ash woodland on the Kennet floodplain, lie on alluvium overlain by a shallow layer of moderately calcareous peat. The wettest areas are dominated by alder Alnus glutinosa over tall herbs, sedges and reeds, but dryer patches include a base-rich woodland flora with much dog’s mercury Mercurialis perennis and also herb-Paris Paris quadrifolia. The occurrence of the latter is unusual, as it is more typically associated with ancient woodland, whereas the evidence suggests that these stands have largely developed over the past century.|
