Kennet Valley Alderwoods is a 57.3abbr=offNaNabbr=off biological Site of Special Scientific Interest west of Newbury in Berkshire.[1] [2] It is a Special Area of Conservation[3]
Located at and at, these woodlands are the largest remaining fragments of damp, ash-alder woodland in the Kennet floodplain. The SSSI includes two woods, the Wilderness and part of Ryott's Plantation, which are important because they support a very great diversity of plants associated with this woodland type, dominated by Alder (Alnus glutinosa), though Ash (Fraxinus excelsior) is abundant in places and there is occasional Oak (Quercus robur) and Wych Elm (Ulmus glabra). In addition to the wide range of higher plants the woods support a diverse bryophyte flora including the uncommon epiphytes Radula complanata, Zygodon viridissimus and Orthotrichum affine.[4]
The site is private land with no public access.
