Dryopteridetum villarii Jenny-Lips 1930

The association Dryopteridetum villarii on Bjelašnica Mt. develops in places of humid ecoclimate, in the zone of mountain-pine woods, close to the Lokvanjsko lake. It is characterized by high proportion of tall herbs: Senecio nemorensis , Lactuca alpina , Solidago virgaurea subsp. minuta . High constancy and diagnostic value show: Dryopteris villarii , Bromopsis erecta , Rumex scutatus , Festuca bosniaca , Hypericum richeri subsp. grisebachii , Campanula scheuchzeri .

In the dendrogram ( Figure 2 ) closely related are A—C group of relevés which are all characterized by high abundance of Drypis spinosa that places them in the alliance Silenion marginatae. The alliance occurs in the northern part of Bjelašnica Mt., which is characterized by less precipitation comparing to the south, with three closely related combination of scree-characteristic species. The diagnosed phytocoenoses differ in terrain inclination (the drainage rate), for Drypidi— Heracleetum orsinii (C) occurs in the upper part of cirques, on steep slopes and very mobile substrate, Drypidi—Silenetum marginatae (A) takes middle section of cirques and less steep ground, whereas Drypido spinosae— Seslerietum wettsteinii (B) occurs on the bottom of cirques.
