After 2000 years of human habitation, it is quite remarkable how much green space remains in this city. This guide charts places all but untouched by human hand: ancient woodland and meadows, marshes and rivers. It also locates those heartening spots where man has lost the battle with nature and wild plants have taken root amid concrete and brick. From the ancient forests of north London to the east's abandoned sewage works, south London's commons and the west's roaming deer, Wild London is your handy guide to finding green among the grey.
