A recent Blog by Richard Coniff presents a critical view to ecological restoration projects, claiming that they often provide an excuse to developers to build over natural habitats, while restoring (often unsuccessfully) secondary sites and at high cost. The author asks critical questions about ecological restoration projects. We are interested to know your opinion!
Recreation of stable land forms and restoring soil productivity are the first tasks of ecological restoration in heavily degraded sites. In previous posts we covered the importance of functional land forms and the role of living organisms in soil formation. In this post we focus on the specifics of soil formation in post-mining sites, thanks to our guest blogger Prof. Jan Frouz.
Soil is closely connected to ecosystem development. In fact, the natural composition of soils is a result of interaction of the mineral substrate with the soil biota: microscopic and macroscopic animals, plants and their physiological activities. Other basic factors, such as the local climate and topography, as well as past developments over long periods of time set the scene. More recent factors, such as technical recultivation measures have a major impact on the restoration and functioning of soils.
