Stadtökosysteme

Stadtökosysteme, also known as urban ecosystems, are communities of living organisms (plants, animals, microbes) interacting with their physical environment within a city. These systems are distinct from natural ecosystems due to the significant influence of human activity and infrastructure. Cities create unique habitats, often characterized by altered temperatures, light availability, soil composition, and water flow.

Key features of Stadtökosysteme include a high proportion of impervious surfaces like buildings and roads, which affect water runoff and temperature regulation. Green spaces, such as parks, gardens, and street trees, play a crucial role in providing habitat, improving air quality, and mitigating the urban heat island effect. These green patches, though often fragmented, support biodiversity and offer essential ecosystem services to urban dwellers.

The biodiversity found in Stadtökosysteme can be surprisingly rich, with species adapted to urban conditions. This can include a variety of insects, birds, small mammals, and a selection of plants that tolerate pollution and disturbed soils. The composition and health of these urban ecosystems are heavily influenced by human management practices, including urban planning, waste management, and conservation efforts. Understanding Stadtökosysteme is vital for developing sustainable cities that balance human needs with ecological health.
