Urban landscapes formerly shaped by heavy industry are evolving all over the world. The associated processes enhance the evolution of a new kind of wilderness. In regions such as the German Ruhrgebiet, vast post-industrial areas have already been re-colonised naturally by forests. These new types of urban woodlands are often overlooked by ecologists, foresters and planners. The book provides a first concise overview of ecological features and potential social functions of this new kind of urban wilderness. The general chapters provide introductions and conceptual approaches from the perspectives of ecology, environmental sociology, forestry, nature conservation and landscape architecture. They are illustrated by a broad array of case studies from England, Germany and Japan.

The outstanding social and ecological roles of urban forests in the growth of cities has become widely known. In many parts of the world, despite or even because of continuing suburbanization, initiatives are being put forth to preserve urban forests, to develop them further and to make them acc- sible to the public. This volume focuses on a particular component of the urban forest - trix – urban wild woodlands. We understand these to be stands of woody plants, within the impact area of cities, whose form is characterized by trees and in which a large leeway for natural processes makes possible a convergence toward wilderness. The wilderness character of these urban woodlands can vary greatly. We differentiate between two kinds of w- derness. The “old wilderness” is the traditional one; it may return slowly to woodland areas when forestry use has been abandoned. The enhancement of wilderness is a task already demanded of urban and peri-urban forestry in many places. This book would like to direct the attention of the reader to a second kind of wilderness, which we call “new wilderness.” This arises on heavily altered urban-industrial areas where abandonment of use makes such change possible. The wild nature of urban abandoned areas was discovered in the 1970s through urban-ecological research. Since then, in a very short time, profound structural changes in industrial countries have led to h- dreds or thousands of hectares in urbanized areas becoming available for natural colonization processes.
