Hales and Shadwell Woods is a 15.4-hectare (38-acre) biological Site of Special Scientific Interest north-east of Saffron Walden in Essex.

[1][2] Shadwell Wood has an area of 7.1 hectares and it is managed by the Essex Wildlife Trust.

[5] The woods, which are under half a mile apart, are both ancient coppice wet ash and maple on chalky boulder clay.

The shrub layer is diverse, with plants including wayfaring-trees, guelder roses, spurge-laurel and the nationally uncommon oxlip.

Seven species of orchid have been recorded in Shadwell Wood, which also has herb-rich grassy rides.
