Abstract


The Ţibleşului Mountains, from the structural point of view, they belong to the sedimentary-eruptive subunit formed by pedogenetical deposits, from which from time to time appear columns of eruptive rocks (andesits), which overwhelm the surroundings with a couple of hundred meters (The Ţibleşului Peak 1842m), being formed in the Miocene. Climatologically it belongs to the provinces Dfk and DfcK, meaning a rainy climate, wet boreal, with hard winters, and cold summers, with an annual medium temperature of 7oC and a multiannual pluviometrical regime of 1100 mm at the lower vegetation limit and 1400 mm at the upper vegetation limit.
The forestry vegetation is represented by The Under Alpine Forestry Vegetation Level (2%), the Mountain Spruce Level, (6%), The Mountain Level Of Mixtures (28%) and The Pre Mountain Level Of Fagus, which is the most frequent (64%).The forestry stations are represented by: Mountain Pre Under Alpine of Spruce Pi, on cliffs end excessive erosion – in the under alpine level; Mountain Of Spruce, Pm, prepodzol-podzol, edaphically average, with Luzula sylvatica, Mountain of Spruce Pi, podzolical, with brut humus, edaphically under average and low, with Vaccinium, in the spruce level; Mountain of Mixtures, Pi, on cliffs and excessive erosion, Mountain of Mixtures, Pi, podzolical, edaphically under average, with moss and other acid likely plants, Mountain of Mixtures, Ps (Pm) districambosoil, edaphically average, with Asperula-Dentaria, in The Level of Mixtures of Fagus With Spruce, Mountain, Pre Mountain of Fagus, podzolical, edaphically average, with Luzula Calamagrotis, Mountain, Pre Mountain of Fagus, districambosiol, eutricambosoil, edaphically average, with Asperula-Dentaria, Mountain Pre Mountain of Fagus Pm, aluvisoil with moderate humus, Mountain, Pre Mountain of Fagus, Ps districabosoil in high plains, in the fagus level.
