Cities are rarely hospitable to wildlife by accident, but a deliberate network of green corridors, connected strips of parkland, tree-lined streets, and planted verges, can make a genuine difference to which species are able to move through an urban area rather than being cut off by roads and buildings at every turn.
Even modest interventions add up: a row of native shrubs along a footpath, a green roof, or a planted median strip can each function as a stepping stone, letting insects, birds, and small mammals move between larger patches of habitat that would otherwise be too far apart to reach safely.
The benefit runs in both directions. Wildlife gains passage through an otherwise hostile landscape, and residents gain more of the everyday contact with nature that green corridors happen to bring along with them, from birdsong on a commute to the simple, steady presence of trees along a familiar street.
