A new endemic plant community with Schoenus nigricans in the Southeastern Alps and northern Dinaric AlpsDakskobler, Igor (Avtor) Martinčič, Andrej (Avtor) Šalamon Verbič, Andreja (Prevajalec) phytosociologysynsystematicsdolomite springsSchoenus nigricansCladium mariscusPrimula carniolicaCaricion davallianaeNatura 2000SloveniaWe 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. 20182026-01-27 14:25:12Neznano25706UDK: 581.9(497.4)ISSN pri članku: 1855-7996DOI: 10.3986/fbg0037COBISS_ID: 43197741slImetniki avtorskih pravic na prispevkih so avtorji
