Rekultivierungsmaßnahmen

Rekultivierung is the process of restoring land and ecosystems after disturbance, with the aim of reestablishing ecological function or returning land to a usable state. The term is widely used in German-speaking countries, particularly for land affected by resource extraction such as mining, but it can also apply to abandoned or degraded agricultural and industrial sites. In practice, rekultivierung encompasses soil restoration, hydrological stabilization, erosion control and the revegetation of the landscape, often with a preference for native species.

The process typically begins with site assessment of soil quality, drainage, contamination, and ecological context. Remediation measures may include replacing or amending topsoil, adjusting soil pH and nutrient levels, and reducing pollutants. Erosion control measures, grading or contouring, and drainage management are used to restore stability. Revegetation follows, using seed mixes or planting plans designed to reestablish vegetation communities and promote biodiversity. Soil biology and organic matter inputs, as well as microbial inoculation, may support long-term fertility. Monitoring and adaptive management are standard components, with success judged by soil health indicators, vegetation cover, biodiversity, and water quality.

In mining regions, rekultivierung is often a legal obligation after closure, with post-closure plans and funding for long-term surveillance. While closely related to renaturierung, rekultivierung commonly emphasizes restoring land for a defined use—such as forestry, agriculture, or recreation—rather than achieving a fully native ecosystem.
