A large heathland common in north-east Hampshire identified by the SPNR as an excellent site for invertebrates and wildflowers. Part of the Common, now designated as a Site of Special Scientific Interest (SSSI), is managed by Hampshire & Isle of Wight Wildlife Trust. Now fragmented by developments such as the M3, the northern part of the Common was bought in 1987 with a gift from Mr and Mrs Clegg who founded Ladybird Books. More recently, the Trust is restoring the wet, flowery grasslands in the southern part of the Common to revitalize its populations of marsh gentians, petty whin and pale heath violets.
