Monkswood Valley (grid reference ST754710) is a 30.7-hectare biological Site of Special Scientific Interest (SSSI) near the village of Cold Ashton, South Gloucestershire, notified in 1990.[1]
Monkswood Reservoir, built in 1896 and now owned by Wessex Water, is situated in the valley of the SSSI.[2][3] The SSSI is woodland and grassland on the sloping land north and south of the reservoir and its tributary.[1]
The woodlands contain Fraxinus excelsior – Acer campestre – Mercurialis perennis (Ash–field Maple–Dog's Mercury) areas,[4] which has limited distribution in Great Britain.[1]
The SSSI has four areas: Monk Woods, Hunterwick Wood & Hartley Wood, Frys Farm and Valley.[5] St. Catherine's Valley SSSI is immediately to the north-east.[6]
The Gloucestershire–Somerset border runs through the reservoir and SSSI. The SSSI is adjacent to the Limestone Link long-distance footpath.
