It is rare to find a landscape untouched by our lines - the hedges, walls, ditches and dykes built to enclose and separate; and the green lanes, roads, canals, railways and power lines, designed to connect. This vast network of lines has transformed our landscape. In 'Linescapes', Hugh Warwick unravels the far-reaching ecological consequences of the lines we have drawn: as our lives and our land were being fenced in and threaded together, so wildlife habitats have been cut into ever smaller, and increasingly unviable, fragments.
