“…It is evident from previous studies (Tintner & Klug 2011;Tintner et al 2012) on Central European landfills that aboveground vegetation differs visually and measurably from natural or semi-natural vegetation in the surrounding habitat. Plant communities respond to external influences and the importance of site factors to plant species composition has been demonstrated repeatedly (Goslee & Sanderson 2010).…”

“…Plant communities respond to external influences and the importance of site factors to plant species composition has been demonstrated repeatedly (Goslee & Sanderson 2010). It has been proved that vegetation can indicate characteristics of landfill cover layer and, in some cases (organic waste), can even indicate some characteristics of the underlying waste, including landfill gases (Tintner & Klug 2011;Tintner et al 2012). The characteristics of communities growing on landfill surfaces depend on the type of succession, whether it was completely natural or human-induced (Baasch et al 2012).…”

etation as the bioindicator of human�induced degradation in karst landscape: case study of waste�filled dolines Mismanagement practices, such as unsustainable waste disposal, created many degraded sites. In karst landscapes, old uncontrolled landfills are often located in dolines (sinkholes). Buried waste material in dolines represents degradation of landform, habitats and a potential danger of groundwater pollution. Buried waste provides heterogeneous ecological conditions on the surface, thus plant communities or individual plant species that developed on the surface of landfills can be used as a bioindicators of waste-filled doline sites and therefore indicators of land degradation. we aimed to discover the potential of vegetation to detect unknown locations of old dumpsites in suffusion dolines in Logaško polje (Dinaric Karst, Slovenia), either by plant communities or by plant species. we aimed to ascertain whether vegetation can indicate the dumping period by estimation of community succession stage. Locations and the age of waste-filled dolines (doline-dumps) were preliminary identified by a historical landscape study. Thus, we used time series of aerial photographs and digital photogrammetry tools for 3D modelling of historical terrain. Ecological evaluation was based on sampling the floristic composition of plots (5x5 m). we analysed ecological conditions by Ellenberg bioindicator values, structure by life history traits and naturalness by hemerobic levels of plants. we studied in detail 30 up to 50-years-old waste-filled dolines that are interspersed by dry and mesic grasslands. Ecological evaluation demonstrated that the main driver of ecological diversity at doline-dumps is the time at which the doline was backfilled and succession started. Annual and eutrophic communities dominate the youngest doline-dumps, middle aged doline-dumps are covered by ni-ACTA CARSOLOGICA 46/1-2017 96 MATEJA BREG VALJAVEC, DANIELA RIBEIRO & ANDRAž ČARNI trophilous perennial forbs and, finally, communities developed towards mesic grassland. we conclude that plant communities in combination with diagnostic plant species can be used as a bioindicators of doline-dumps in agricultural landscape of Logaško polje and can therefore indicate the sites of potential groundwater pollution sources but not the type of long-time buried waste.

“…This approach was realised for mechanically-biologically treated municipal solid waste and composts [26,27]. For old landfill materials prediction did not lead to reliable results because chemical (spectral) characteristics do not adequately reflect the biological behaviour at low reactivity levels [4]. Mineral components affect the biological behaviour although biodegradable substances are still present and visible in the spectrum.…”

“…Moreover, the biological tests are error-prone at low values. It should also be emphasised that the C-H vibrations of the aliphatic methylene group that are an essential indicator of decomposing biomolecules in fresh waste materials are rather assigned to plastics in old landfill materials which was confirmed by thermal analysis [4]. Due to these reasons classification by SIMCA was applied.…”

“…Especially greenhouse gases have become a crucial topic due to their global effect and the contribution to climate change. The fate of carbon, a key element in the global cycle, therefore attracts much attention [1][2][3][4]. Carbon sequestration and minimisation of gaseous emissions such as CO2 and methane are promoted to decelerate the turnover.…”
