I. Trinajstić: FITOCENOLOŠKO-SINTAKSONOMSKE ZNAČAJKE ŠUMA CRNIKE – Quercus ilex L... Šumarski list br. 9–10, CXXXI (2007), 431-434
the number of slecies per one relévé is very small. A significant place in the
floristic composition is occupied by the elements of the Quercetalia pubescentis
order. These are Carpinus orientalis, Quercus pubescens, Acer monspessulanum,
Fraxinus ornus, Coronilla emeroides, Sesleria autumnalis and Tamus
communis. However, in the group of evergreen elements two relatively significant
evergreen species – Myrtus communis and Pistacia lentiscus, are mising.
It must be pointed out that obth these species had been noted earlier in the
flora of the island of Krk (cf. Tommasini 1875, Lusina 1933), but during
phytosociological research they have not been registered.


On the island of Krk the Carpino orientali-Quercetum ilicis association is
on its northern ecological boundary, so there it grows on the southern exposition
slopes only up to the altitude of 60 m, in the form of low forest or high
macchia and with interruptions from Stara Baška (punt Črnika) in the east to
the Valbiska cove in the west.


Among the combinations of species with which Quercus ilex comes, from
the most thermophilous ewergreen ones to the most mesophilous deciduous
ones, the rarest is the combination where Quercus ilex together with Carpinus
orientalis. The most likely reason for this is that in the southern Istria and on
the island of Krk only, in the boundary belt between evergreen and deciduous
vegetation Q. ilex is accepted as an evergreen species and C. orientalis as a
deciduous one. Other deciduous elements auch as Fraxinus ornus and Ostrya
carpinifolia build large stands in certain parts of the Mediterranean but Carpinus
orientalis is never found in them.


Due to the decrease of pressure on the forests of the island of Krk for firewood,
the forest vegetation was regenerating rapidly over the last 40 years,
but in the case of the holm oak stands, such as, for instance, those in the Valbiska
cove where the car-ferry landing is located, they are endangered by
devastation caused in the first place by various construction activitis.
