The latest in the New Naturalist series documents the parks and green spaces unique to Britain's cities - and the wildlife that has flourished in these habitats. Not since Richard Fitter's landmark publication in 1945, `London's Natural History' - volume 3 in the New Naturalist series - has there been a comprehensive guide to urban natural history. Since then there have been major advances in the conservation of nature in our towns and cities, and there is even more to say about how animals and plants have adapted, in varying degrees, to urbanisation. But this is not merely an exploration of natural history within the urban environment - David Goode uses his knowledge of urban ecology to describe the range of habitats and species which exist within urban areas, and shows how our understanding is being applied to encourage a greater variety of nature into towns and cities. He illustrates how an ecological approach can be incorporated within planning and design to create a range of habitats from tiny oases to extensive new urban woodland and wetlands.
