Staines Moor is a Site of Special Scientific Interest at the NW corner of Surrey, England. It is around 2 sq km in area, and consists of rough pasture. The River Colne, Hertfordshire runs through it. It lies between Staines to the south and the village of Stanwellmoor to the north.
The Staines Moor SSSI also includes King George VI Reservoir which is to the east. The reservoir carries nationally important wintering populations of tufted ducks, pochard, goosander and goldeneye. The moor is separated from Wraysbury Reservoir to the west by the M25 and a disused railway viaduct. It is owned by Thames Water.[1]
