Phytosociological analysis of Gladiolus palustris sites in northwestern, western and southwestern Slovenia / Fitocenološka oznaka rastišč vrste Gladiolus palustris v severozahodni, zahodni in jugozahodni Sloveniji

With a phytosociological analysis of more than 200 releves 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 Banjsice Plateau and the Slavnik range in Cicarija, but the current nature conservation policy in Slovenia does not provide for its preservation.

Ugotovili smo, da obe podobni vrsti lahko uspevata na skupnih nahajaliscih in rastiscih, toda vrsta Gladiolus palustriscveti vsaj 14 dni kasneje kot vrsta Gladiolus illyricus. Zanesljiv znak za njuno razlikovanje so vlakna, ki obdajajo njun gomolj. Na vecini preucenih nahajalisc je mocvirski mecek ogrožen in mu zdajsnja naravovarstvena politika v Sloveniji ne zagotavlja ohranitve, izjema sta planoti Banjsice in pogorje Slavnika v Cicariji.
