“…Therefore, the role of these elements (Cd, Cu, and Zn) (Figures S1, S3) on soil microbes belonging to different IAA types requires additional research. The severe deficiency of N remains a major challenge for ash management (Tropek et al, 2014). Our results show nitrogen enrichment in S. ravennae rhizosphere with the age of dump ( Figure S1).…”

“…Recently, it has been recognized that technical reclamations destroy the conservation potential of terrestrial communities at post-mining sites, whereas spontaneous succession serves as a much more efficient restoration tool in terms of biodiversity protection (e.g. Hodačová and Prach 2003;Tropek et al 2010Tropek et al , 2012Tropek et al , 2014Mudrák et al 2010;Hendrychová et al 2012;Š álek 2012;Š ebelíková et al 2015). The only comparison of freshwater communities at differently restored sites (Harabiš et al 2013) showed that stagnant freshwaters at technically reclaimed spoil heaps and at spontaneously developed sites are fully comparable in terms of the conservation value of dragonfly communities.…”

Headwaters and small streams are crucial components of riverine systems, harbouring many highly specialized and unique invertebrate species. Unfortunately, the overwhelming majority of the Central European lowland headwaters are channelized, eutrophicated and/or polluted, and many related species have become critically endangered. Artificial streams established to drain some post-mining sites supplement a network of headwaters and generally do not suffer from agricultural pollution. Nevertheless, the biodiversity and conservation potential of the streams at post-mining sites has never been evaluated. We studied the biodiversity of dragonflies and damselflies (Odonata) at 53 sections (30 m) of an extraordinarily dense system of drainage ditches at a large lignite spoil heap in the Czech Republic. We recorded 22 dragonfly species, of which eight are threatened according to the national Red List. Moreover, four of them are closely associated with the endangered environment of small streams. Overall diversity was generally low at very tiny and/or narrowed streams and was also strongly reduced by high water velocity, high bankside inclination and dominance of expansive common reeds. Sufficient cover of rather shallow sediment layers strongly supports the studied diversity indicators. We thus conclude that post-mining streams in drainage ditches could have a strong potential to offer secondary habitats for threatened headwater biodiversity. However, intermittent reed suppression and the establishment of gently sloping banks and a structured stream bottom are necessary measures for maximizing post-mining stream conservation.

“…Recently, the virtually unknown diversity of arthropods colonising fly ash deposits has been surveyed, and these post-industrial sites were revealed as crucial refuges for many critically endangered arthropods (including several species considered as regionally extinct) otherwise confined to drift sands, a habitat close to evanishment (Tropek et al 2013a(Tropek et al , 2014. Although the studies are still in their infancy, it is hypothesised that the finely grained fly ash shares some physical attributes with aeolian sands and thus mimics habitats for various psammophilous (i.e.…”

“…highly specialised on the extreme conditions of sand dunes) species (Tropek et al 2013a). Due to the lack of complex studies (with the exception of Tropek et al (2014)), together with the high controversy of the fly ash deposits, we see this problem as one of the main challenges of current restoration ecology. Considering the importance of both conservation value and environmental risks, a search for a compromise in restoration methods is urgently needed.…”

Recently, fly ash deposits have been revealed as a secondary refuge of critically endangered arthropods specialised on aeolian sands in Central Europe. Simultaneously, these anthropogenic habitats are well known for their negative impact on human health and the surrounding environment. The overwhelming majority of these risks are caused by wind erosion, the substantial decreasing of which is thus necessary. But, any effects of anti-dust treatments on endangered arthropods have never been studied. We surveyed communities of five arthropod groups (wild bees and wasps, leafhoppers, spiders, hoverflies and orthopteroid insects) colonising three fly ash deposits in the western Czech Republic. We focused on two different anti-dust treatments (~70 and 100 % cover of fly ash by barren soil) and their comparison with a control of bare fly ash. Altogether, we recorded 495 species, including 132 nationally threatened species (eight of them were considered to be extinct in the country) and/or 30 species strictly specialised to drift sands. Bees and wasps and leafhoppers contained the overwhelming majority of species of the highest conservation interest; a few other important records were also in spiders and orthopteroids. Total soil cover depleted the unique environment of fly ash and thus destroyed the high conservation potential of the deposits. On the other hand, partial coverage (with ~30 % of bare fly ash) still offered habitats for many of the most threatened species, as we showed by both regression and multivariate analyses, with a decrease of wind erosion. This topic still needs much more research interest, but we consider mosaic-like preservation of smaller spots of fly ash as one of the possible compromises between biodiversity and human health.
