Abstract: Revitalisation of contaminated brownfield sites is essential for sustainable development, particularly near sensitive ecological areas like Natura 2000 sites. The lagoon in Slovenia’s Regional Park Šturmovci, an artificial wastewater convergence point created during hydroelectric construction, is a highly relevant example. This study integrates geochemical, mineralogical and isotopic analyses to identify sources and controlling mechanisms of contaminant distribution in lagoon sediments and assess their transfer to nearby agricultural soils during flooding events. Results indicate anaerobic conditions, with depth-related shifts in phosphorus, sulphur and redox-sensitive elements, such as rare earth elements (REE), arsenic (As), barium (Ba), cobalt (Co), chromium (Cr), lead (Pb) and vanadium (V), as well as fluctuations in pyrite-rich laminated layers, suggesting potential flood-driven remobilisation of trace elements. Lagoon sediments are highly contaminated with As (73 mg kg−1), Ba (247 mg kg−1), Pb (97 mg kg−1) and Zn (1118 mg kg−1), with elevated concentrations also observed in agricultural soil, all exceeding respective limit values of 20, 160, 85 and 200 mg kg−1. Pollutant concentrations were highest near wastewater inflows and decreased with distance, with nitrogen isotopic patterns indicating partial nitrification and surface ammonium accumulation, reflecting intensive agricultural inputs in the area. High enrichment factor (EF > 20) and geoaccumulation index (Igeo > 3) values, in particular for As, Cd and Zn, indicated severe contamination and highlighted the urgent need for effective remediation strategies, including immobilisation using biochar or cement-based binders, as well as phytoremediation approaches.

Abstract: We studied the phytosociology of plant communities with Schoenus nigricans, a character species of the alliance Caricion davallianae, in western Slovenia. Most of our relevés are classified into the new association Astrantio carniolicae-Schoenetum nigricantis, whose stands grow on moist rocks and in the headwater section of springs and small brooks in dolomite wooded areas, especially in the Cerkno region, in the basin of the Idrijca river. Its character species and (geographical) differential species are Schoenus nigricans, Molinia arundinacea, Astrantia carniolica, Palustriella commutata, Carex flacca, Valeriana saxatilis, Salix glabra, Erica carnea and Primula carniolica. In addition to the typical form (subassociation -typicum) we described also the subassociation with predominating Cladium mariscus (-cladietosum marisci). The studied dolomite headwaters are a Natura 2000 habitat type and the sites of several vulnerable and protected species. Their role as a biotope is therefore significant and requires adequate protection.

Abstract: V članku smo povzeli rezultate naših raziskav rastja in rastlinstva v povodja Gačnika na Vojskem in v Trebuši v zahodni Sloveniji. Naštevamo najbolj pogoste in najbolj značilne rastlinske združbe, zavarovane in redke rastline in naravovarstveno vredne habitatne tipe. Slednjih je vsaj sedem. V njihovih združbah uspevata dve Natura 2000 vrsti (Primula carniolica, Cypripedium calceolus) in skoraj 60 zavarovanih in (ali) redkih cevnic (rdeči seznam). Med združbami so najbolj ogrožena mokrišča (nizka barja in mokrotni travniki) in njihove značilne vrste: Drosera rotundifolia, Dactylorhiza lapponicasubsp. rhaetica, D. traunsteineri, Eleocharis quin­queflora,Eriophorum angustifolium, E. latifolium, Pinguicula vulgaris in Trichophorum alpinum.

Abstract: With a phytosociological analysis of more than 200 relevés on more than 25 localities with Gladiolus palustrisand (or) G. illyricusin western and southwestern Slovenia we identified more than 15 communities of association rank that belong to at least eight vegetation alliances and five classes. We determined that these two species can grow on the same localities and sites, but Gladiolus palustrisflowers at least 14 days after G. illyricus. Another reliable distinguishing characteristic is the fibrous tunic covering the corm. Gladiolus palustris is threatened in most of the examined localities, except for the Banjšice Plateau and the Slavnik range in Čičarija, but the current nature conservation policy in Slovenia does not provide for its preservation.
