The dynamic effects of globalisation cause constant changes of peri-urban land use and produce industrial and urban brownfields which are also potential places for a new, secondary type of wilderness. Today brownfields on former sites of heavy industry are well known for wild vegetation. The majority of future brownfields in urban regions will be found on small – scale commercial sites and only a few of them will be changed into public parks. The majority will have wild vegetation that is managed in a specific way to enable the reuse of the land in the future.
New wilderness for flora, fauna and habitats
Other areas for wild vegetation are created by legal regulations to compensate for the ecological losses of urbanisation. As a result, areas of new wilderness are established for flora, fauna and habitat purposes. A better understanding of the ecological benefits of dynamic changes to habitats has led to a change in strategy for the vegetation management of these areas (Wulf 1995) that aims at integrating natural development.
New wilderness as land reserve
New wilderness could also be situated on land that is temporarily not used, such as areas kept in reserve for urban development (especially traffic infrastructure). Some of these sites remain unused for longer periods because changes in planning and budget problems cause delays. The natural vegetation that develops on there could be managed as a (secondary) new wilderness as an interim solution.
