Hedgerow is now considered the greatest edge habitat on earth: it offers thorny scrub, mature woodland, grassland and even wetland. It plays a critical role in carbon sequestration, provides essential protection against the elements, and is a vital habitat on farmland. In this journey around the wild edges of Britain, discover the life, ecology and history of the humble hedge: the hawthorn and hazel of ancient hedges; the abundance of wildlife, such as dunnock and nightingale, hedgehog and harvest mouse; and the free pickings that the hedgerow offers.
