Two new scree plant communities in the Triglav Mountains (Julian Alps, Slovenia) / Dve novi rastlinski združbi melišč v Triglavskem pogorju (Julijske Alpe, Slovenija)

Abstract

In the Triglav Mountains, mainly on the slopes and plateaus to the west of Mt. Triglav (Glava v Zaplanji, Vrh Zelenic) we found new localities of three rare species of Slovenian flora, Crepis terglouensis, Cerastium uniflorum and Geum reptans, and made a phytosociological inventory of their sites. Based on comparisons with similar communities within which they occur elsewhere in the Eastern and Southeastern Alps we described two new associations, Crepido terglouensis-Potentilletum nitidae (alliance Thlaspion rotundifolii) and Saxifrago carniolicae-Cerastietum uniflorae (alliance Arabidion caeruleae).

V Triglavskem pogorju, predvsem na pobočjih in planotah zahodno od Triglava (Glava v Zaplanji, Vrh Zelenic) smo našli nova nahajališča treh redkih vrst v flori Sloveniji, Crepis terglouensis, Cerastium uniflorum in Geum reptans in fitocenološko popisali njihova rastišča. Na podlagi primerjav s podobnimi združbami, v katerih uspevajo omenjene vrste drugod v Vzhodnih in Jugovzhodnih Alpah, smo opisali dve novi asociaciji Crepido terglouensis-Potentilletum nitidae (zveza Thlaspion rotundifolii) in Saxifrago carniolicae-Cerastietum uniflorae (zveza Arabidion caeruleae).
