“…However, soil invertebrates play an important role in the development of post-mining sites, namely in soil formation. On the other hand they can be sensitive indicators of ecosystem restoration in post-mining sites (Dunger, 1991;Keplin et al, 2000, Frouz et al, 2001. Several tests were developed to test the toxicity of various chemicals (mostly pesticides and heavy metals) for soil invertebrates (Westheide et al, 1993;Donkin and Dusenbery, 1993;ISO 16387: 2003 (E); Trublaevich and Semenova, 1997;Römbke et al, 1998;Crouau and Cazes, 2003).…”

Laboratory-reared cultures of Enchytraeus crypticus were used in a reproduction toxicity test to evaluate the toxicity of 46 spoil substrates collected in four brown coal mining areas in the Czech Republic and Germany. A set of substrate parameters (pH, conductivity, Na, Ca, K, Al, Fe, loss of ignition and polyphenol contents) were measured for each spoil and correlated with spoil toxicity for E. crypticus. Toxicity increased with decreasing pH and increasing Al, Fe content. Spoil with a pH below 3 did not support the survival of E. crypticus. However, some alkaline spoils with high conductivity and ion concentration were also toxic. Toxicity was positively correlated with the loss of ignition and polyphenol content. The results indicate that the toxicity of post-mining spoil substrates have multiple origins. Most frequently the toxicity of post-mining substrates corresponds with low pH and consequent toxicity of Al and Fe. However some substrates may be toxic due to high ion concentrations. The potential role of fossil organic matter (namely polyphenols) in toxicity of post-mining substrates requires further research.

The restoration of surface mining landscapes requries the (re)creation of ecosystems. In Lusatia (eastern Germany), large-scale open-cast lignite mining operations generated spoil dumps widely consisting of acidified, phytotoxic substrates. Amelioration and rehabilitation measures have been developed and applied to these substrates since the 1950s. However, it is still not clear whether these approaches are sustainable. This paper reports on collaborative research work into the ecological potential of forest ecosystem development on typical minesites in the Lusatian lignite district. At first sight, pine stands on minesites along a chronosequence comprising about 35 years did not show differences when compared with stands on non-mined sites of the general region. Furthermore, with some modification, conceptual models for flora and fauna succession in forest stands on non-mined sites seem to be applicable, at least for the early stages of forest ecosystem development. For example, soil organism abundance and activity at minesites had already reached levels typical of non-mined sites after about 20-30 years. In contrast, mine soils are very different from non-mined soils of the test region. Chemically, mine soil development is dominated by processes originating from pyrite oxidation. Geogenic, i.e. lignitic, soil organic carbon was shown to substitute for some functions of pedogenic soil organic matter. Rooting was hampered but not completely impeded in strongly acidified soil compartments. Roots and mycorrhizae are apparently able to make use of the characteristic heterogeneity of young mine soils. Considering these recent results and the knowledge accumulated during more than 30 years of research on minesite rehabilitation internationally, it can be stated that minesite restoration might be used as an ideal case study for forest ecosystem development starting at "point zero" on "terra nova".
