Reed Hill is a 14-hectare (35-acre) biological Site of Special Scientific Interest (SSSI) west of Stonesfield in Oxfordshire.[1][2] It partly overlaps Stonesfield Slate Mines SSSI.
This sheltered dry valley has unimproved limestone grassland, secondary woodland and scrub. A spring at the northern end makes the ground there seasonally damp. Invertebrates include the small blue, Duke of Burgundy and dark green fritillary butterflies, the small shield bug Neotti-glossa pusilla, the beetle Oedemera lurida and the spider Hypsosinga pygmaea.[3]
