A historical approach: from pristine to urban-industrial woodlands

Independent of their location relative to urban agglomerations, peri-urban as well as non-urban woodlands can vary tremendously in their origins and development history. In addition to the spatial dimension illustrated in Ta­ble 1, the urban woodland matrix is also determined by its origins. In this second dimension, four woodland types can be differentiated (Table 2). […]

Exchange of species

The spatial interweaving of urban woodlands and developed areas favors the exchange of species in both directions. Numerous cultivated plants dis­perse themselves as escapees from gardens and parks into neighboring woodlands or are carried into such areas as garden waste (Hodkinson and Thompson 1997). Urban woodlands are generally rich in non-native spe­cies especially along their […]

Deposition of materials

Peri-urban woodlands are especially affected by wet or dry deposition as well as that resulting from recreational activities. The spread of nitrophi – lous species is interpreted to be a result of nitrogen deposition (Kowarik and Sukopp 1984). Muller et al. (1978) correlated the presence of high-N indicator species (Ellenberg’s indicator species) with the use […]

Habitat fragmentation

Urban uses often lead to the fragmentation of woodlands and to stark divi­sions within stands through intended and unintended paths and horseback­riding trails as well as roads. In this way, small woodland patches with high edge-to-interior ratios are created. Forest fragmentation generally en­hances pioneer species or non-native species that respond well to an in­creased availability […]

Preface

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 acces­sible to the public. This volume focuses […]
