Elstead Common is a Site of Special Scientific Interest, as are neighbouring Ockley and Royal commons (Walks with Rena post for the latter is here). All are managed by Surrey Wildlife Trust on behalf of the MOD. Elstead and Ockley commons are recognised as some of the finest remaining lowland heath in the south of England and are awash with heather, gorse and bracken. The woodlands on its perimeter are primarily made up of birch and Scots pine.
