What is Urban Wilderness?

The development of urban wilderness is closely linked to the history of industrialization and urban decline. As manufacturing centers shifted or closed, large tracts of land were left vacant, allowing natural succession to occur without human intervention.

Notable instances include the High Line in New York (before its conversion to a park) and various post-industrial landscapes in European cities like Berlin, where abandoned railyards have become protected nature reserves.

Urban wilderness represents a unique intersection between human-made infrastructure and natural ecological processes. These sites are characterized by spontaneous colonization by flora and fauna.

These areas provide essential ecosystem services, including carbon sequestration, stormwater management, and the mitigation of urban heat. They also serve as critical corridors for migratory species.

The mechanism relies on ecological succession, where pioneer species colonize disturbed soil. Over time, these species modify the environment, allowing more complex plant and animal communities to establish themselves.
