“…The species are mainly hemicryptophytic, often spread by rhizomes and build dense stands. The sites are humid and fertile (Pastor et al 2014;Shushpannikova 2014). These communities indicate that at least the upper horizons of the doline have been filled with organic waste, which has provided the fertility to the site.…”

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.

“…Besides the habitat conditions, both the manner and intensity of land use have an impact on the persistency and floristic diversity of these communities. Interference with the habitat conditionsthrough regulating the hydrologic regime, limiting the intensity of use or its abandonment -leads to changes in the species composition and size of the area covered by plant communities [1][2][3]. Modern agricultural trends result in increasing the area of land excluded from use, including grassland [4].…”

Vegetation changes of the Molinio-Arrhenatheretea class in the Bystra valley, eastern Poland

et al. 2016

The study objective was to analyze and assess the vegetation changes of the meadows (Mo linio-Arrhenatheretea class) located in the valley of the Bystra River in eastern Poland after a period of 38 years, and to identify the direction of plant communities succession. The studies were conducted in the years 1973 and 2011 on grasslands belonging to farmers. The floristic diversity was identified based on the phytosociological structure and mean number of species calculated based on the number of species in the particular relevés of the phytocenosis under study. The highest frequency of occurrence was demonstrated by the Poa pratensis-Festuca rubra community within which more than half of the patches persisted over the 38-year period. New communities (Scirpetum sylvatici, Alopecuretum pratensis, Lythro-Filipenduletum) appeared after the withdrawal of habitats of the Phragmitetea class, due to the lowering of the groundwater level. A portion of the meadows and pastures were transformed into arable fields, gardens or building plots. Among ecological indicators, the greatest differences were observed in the mean soil moisture values between the two years compared, both for all meadows and the predominant community, which indicates an increase in habitat humidity.
