In this article we presented general characteristics of 13 pre-forest and forest habitat types (Natura 2000) in Slovenia (4070*, 9110 9180*, 91D0*, 91E0*, 91F0, 91K0, 91L0, 91R0, 9340, 9410, 9420, 9530*) and evaluated their general conservation status on the basis of the existing data. For three most wide-spread forest habitat types in Slovenia (91K0 Illyrian oak-hornbeam forests, 9110 Luzulo-Fagetum beech forests, 91L0 Illyrian oak--hornbeam forests) we presented the expected range of tree species share, which is one of the key parameters and represents an important starting-point for evaluating conservation condition of habitat types. We set out important nature conservation features for every individual habitat type and, above all, its importance as the sites of diverse conservationally important, rare and protected plant species. We analyzed present disturbances and threats for its existence in the future for every habitat type. We prepared general instructions for management and interventions into these forests according to the groups of functionally similar forest habitat types.

In the article we deal with twelve pteridophytes and spermathophytes of European conservational importance growing in Slovenian forest areas, above all from the viewpoint of impact of spatial interventions (construction of traffic roads, logging, harvesting) on their sites. Presence of these species at forest sites usually represents no obstacle for management, but it requires appropriate adjustments which should comprise selection of harvest road routes, prohibition of major logging or clear cut, felling out of vegetation season. We recommend skipping eco cells where only felling of individual trees is allowed in the zone from one to two tree heights from the site. Most times, such management adjustments are needed at sites of Cypripedium calceolus, Eleocharis carniolica and Primula carniolica.

In this paper the first attempt of large scale habitat evaluation in Slovenia is given for four forest beetle species of European conservation concern: Rosalia alpina, Morimus funereus, Cucujus cinnaberinus, and Lucanus cervus. From selected large-scale databases the habitat selection characteristics were analysed and maps of potential forest habitat suitability were developed. The maps were validated in the field. From this turn out only the spatial model for Rosalia alpina appeared to be acceptable. The analysis of proportion of inclusion of potential areal of selected beetle species into current Natura 2000 network revealed some deficiencies. The present first models developed for Natura 2000 species are presented should be improved by supplementation of data and improvement of more targeted samplings in future studies. It is advised to use the same method for other Natura 2000 qualification species as well.

In the article, we present the first attempt of a large scale habitat evaluation which we performed on four bird species of European conservation concern: Capercaillie (Tetrao urogallus), Ural Owl (Strix uralensis), White- -backed Woodpecker (Dendrocopos leucotos), and Collared Flycatcher (Ficedula albicollis). With the use of existing large-scale databases we analysed the habitat selection and the potential distribution of the four species. Since all species are forest specialists, distance to the nearest settlement or to the agricultural land was an important habitat parameter. For most of the species we found also that the stand growing stock was important, which indicates the significance of presence of older developmental stages in the forests. These models are the first of this kind in Slovenia. However, upgrading with additional field data is necessary. Furthermore, in the context of nature conservation and specifically Natura 2000 is important this procedure is also done for other species.

In the paper the mathematical model evaluating conservation status of forest habitats and habitats of the species is presented. The model is based on fuzzy logic and indicators are joined by inference rules. First empirical values of indicators are transformed into linguistic variables poor, acceptable and favorable and their membership functions are defined. Then inference rules between linguistic variables and final output are defined. The final result is expressed with number and linguistic value. The model was developed for conservation status of forest habitat types. Use of the model was shown for the forest management plan of forest management unit Snežnik and for conservation status of saproxylic beetles, for which the use was shown for the forest management plan Trnovo.
