Abstract

With phytosociological relevés we documented at the rank of association more than ten forests communities in the Liščak basin in the southern Julian Alps. Due to its geological (limestone, marlstone, claystone, chert) and geomorphological specifics (steep slopes, south-facing gorge) the stands of associations Seslerio autumnalis-Fagetum and Saxifrago cuneifolii-Fagetum prevail. We identified similarities and differences between narrow and deep gorges and ravines in the Julian Alps by comparing flora and vegetation in the Liščak basin and the Vintgar Gorge at Podhom, and described two new syntaxa.

Key words: vegetation, flora, synsystematics, Kneška Grapa gorge, Vintgar Gorge, Triglav National Park, Natura 2000 

 

Izvleček

V povodju Liščaka v južnih Julijskih Alpah smo s fitocenološkimi popisi in preglednicami dokumentirali več kot deset gozdnih združb na rangu asociacije. Zaradi njegovih geoloških (apnenec, laporovec, glinavec, roženec) in geomorfoloških posebnosti (velika strmina, usmerjenost grape proti jugu) prevladujejo sestoji asociacij Seslerio autumnalis-Fagetum in Saxifrago cuneifolii-Fagetum. Podobnosti in razlike ozkih in globokih grap in sotesk v Julijskih Alpah smo ugotavljali na podlagi primerjave rastja in rastlinstva povodja Liščaka in soteske Vintgar pri Podhomu in pri tem opisali tudi dva nova sintaksona.
