This book is about the plants and animals of urban areas, not the urban fringe, not encapsulated countryside but those parts of towns where man's impact is greatest. The powerful anthropogenic influences that operate in cities have, until recently, rendered them unattractive to ecologists who find the high proportion of exotics and mixtures of planted and spontaneous vegetation bewildering. They are also unused to considering fashion, taste, mowing machines and the behaviour of dog owners as habitat factors. I have always maintained, however, J. nd I hope this book demonstrJ. tes, that there are as many interrelationships to be uncovered in a flower bed as in a field, in a cemetery as on a sand dune; and due to the well documented history of urban sites, together with the strong effects of management, they are frequently easier to interpret than those operating in more natural areas. The potential of these communities as rewarding areas for study is revealed in the literature on the pests of stored products, urban foxes and birds. The journals oflocal natural history societies have also provided a rich source of material as amateurs have never been averse to following the fortunes of their favourite groups into the heart of our cities. It is predictable that among the few professionals to specialize in this discipline have been those enclosed in West Berlin, who must he regJ. rdcd as among the leJ. ding exponents of urban ecology.

This book provides a guide to habitat creation and repair, from the ethics and principles to the practical detail of designing habitats for wildlife. With chapters spanning all the major types of habitat to be found in the UK, the book gives advice on deciding when habitat creation is the correct path to follow, and then covers all steps from site survey through to the final design and actual realization of the scheme. For each habitat, the book describes the options, problems, and solutions most likely to be encountered, and gives examples of good and bad habitat creation in practice. No other such comprehensive and up-to-date book currently exists on habitat creation.
