Blechnum spicant, Abies alba, Oxalis acetosella and Phegopteris conectilis, which belong to the class of holarctic coniferous forests (Vaccinio-Piceetea) and indicate a higher level of habitat acidity. The Lipje relevés were distinguished from the other fir-beech subassociations mainly by species Epimedium alpinum, Carpinus betulus, Helleborus dumetorum, Quercus petraea, Hedera helix, Melica uniflora, Euonymus europaea, Galium album, which can mainly be classified in the alliance of thermophilous Illirian oak-hornbeam woods (Erythronio-Carpinion) or class of termophillous oak forests of Submediterranean regions (Quercetalia pubescentis). The Lipje forest reserve seems to be most related to hornbeam and fir-beech phytocenoses of lower altitudes and carbonate bedrock in the surrounding region, particularly to the secondary hornbeam phytocenoses, classified as Asperulo-Carpinetum, which grow on abandoned agricultural areas or degraded, potential beech habitats.
Shannon-Wiener index values indicated a greater degree of diversity in the Lipje relevés compared to fir phytocenoses and a slightly lower degree compared to hornbeam and submontane beech forests (Figure 5 upper right corner).
