Desire lines map the places where town planning and free spirits meet. They are the paths made by man or beast that developers didn't foresee. Shortcuts across grass or municipal flowerbeds are sometimes eventually paved, but planners are perhaps getting better at imagining the routes humans - and hedgehogs - might want to tread. Conservation charity the RSPB is working in partnership with Barratt Developments to give nature a home at new building sites by implementing ideas such as hedgehog highways (access built into housing plans such as holes in fences, and hedgerow corridors). The charity has a Head of Sustainable Development responsible for Urban Recovery (looking at urban bird species of concern), and will soon recruit a Swift Ambassador.
RIBA (Royal Institute of British Architects) offers a Designing For Biodiversity guide. When I visited Phase 1 of local premium development Ninewells Cambridge, a quick sketch of bat and swift boxes had only recently been added (admittedly a bit of an afterthought). Their luxury literature states: 'Ninewells is as much about the natural world as it is about the connection with the city... did you know that Ninewells takes its name from a local nature reserve? Nine Wells, a historically important source of the Hobson Conduit, once provided Cambridge with its drinking water'.
The human inhabitants of Ninewells are lucky. Paths and cycleways will lead to Addenbrooke's hospital and bus station and open countryside via 'green fingers' landscaped with flowerbeds, trees, hedgerows and allotments. Quite utopian really. The idea of the cul-de-sac is old hat, and thank goodness for that. There's one near me that swallows people up and never lets them out. The far perimeter of their housing estate was planted with trees to disguise the point at which the development met the greenbelt. A high fence still reaches all the way round. Desire lines to the public footpath across the fields next door never had a chance.
