This paper presents new typology of Slovenian forests sites, based on ecological and floristic similarity of forest plant communities. The first main group consists of forest site types on the carbonate and mixed carbonate-silicate rocks. In the second main group are forest site types on the silicate rocks. Forests on the carbonate and mixed carbonate-silicate rocks have been classified into five altitudinal belts: lowland forests, colinar-submontane forests, submontane-montane forests, montane-altimontane forests, altimontane-subalpine forests. Forests on the silicate rocks have been classified into four altitude zones: colinar-submontane forests, submontane-montane forests, montane-altimontane forests, altimontane-subalpineforests. In this paper we propose a new Slovenian description for forest site types, show a link to the system of forest community names (syntaxa) in the previous database of Slovenian Forest Service and to the newer names of forest syntaxa.

Forest-management planning involves more and more items related to nature conservation which is also provided by the relevant legal acts. Although the nature conservation concern is primarily focused to the habitat types and species within the European ecological network of Natura 2000 areas, in the concept of sustainable forest management attention needs to be paid to the forest habitat types (Habitat Directive, 1992) on their entire area. In the analysis, we found that, mainly due to objective circumstances, some forest and scrubland habitat types have not been adequately addressed in the forest management planning system so far. In this paper we have demonstrated the possibility of using more recent Typology of Slovenia forest sites (2012) for conservation purposes. Possibilities of classification in the appropriate habitat type were shown for each site type described on the basis of ecological and floristic similarity of the related forest plant communities. We encountered a degree of uncertainty in classification of forests in the habitat type 9410 Acidophilous Picea forests of the montane to alpine levels (Vaccinio-Piceetea) and the habitat type 9110 Luzulo-Fagetum beech forests. Although the nature fir forests have considerable nature conservation importance, they were not adequately integrated into the existing concept of nature conservation. Therefore, we propose to describe the fir forests in Slovenia and to take measures for their nature-conservation treatment.

The spruce mires and forests on the Pokljuka plateau are characterised by very diverse ecological conditions, plant species diversity, and a high variability of spruce-tree growth. The ecological conditions are well indicated by the floristic composition and vegetation. Therefore, based on the similarity of the floristic composition, plant-species cover and vertical vegetation structure, the studied spruce mires and spruce forests were clustered into six eco-vegetation groups. The growth characteristics of the spruce trees were tested among different eco-vegetation groups. The differences in the mean age of the spruce trees among the eco-vegetation groups are not significant. However, significant differences in the spruce-tree growth regime between trees growing on the mires and in the forest have been confirmed. The significant differences in mean tree height, mean tree breast diameter and in mean tree-ring widths have been established. The slow growth of spruce trees on the mires can be explained by harsh ecological conditions, especially by high soil water content and high ground water level.
