Fagus sylvatica is a dominant tree (with the height of 35-40 m). Quercus robur and Quercus petraea have their ecological optimums there with the representation of up to 30%. Abies alba occurs in the crown level with the representation of up to 10%. 4th occupies 35.2% of the study area - from 310 m a.s.l. up to 650 m a.s.l. Fagus sylvatica is dominant (the height over 50 m). Abies alba occurs in the co-dominant level (sporadically in the level exceeding the main level) with the representation of ±20% and the height of up to 50 m. Quercus petraea and Quercus robur occur only as an interspersed species with the representation of up to 10%, they do not reach the co-dominant tree level any more. Carpinus betulus is represented regularly only in the overtopped tree level.

The European beech is one of the most suitable and most frequently used tree species in this process. Modern technologies of intensive methods of the cultivation of the European beech seedlings provide, among others, a possibility to increase the proportion of this tree species in reforestation more quickly. It is however necessary to test at what types of sites this planting material can be used. The health status and growth of intensively grown beech seedlings in the first years after planting were studied on 2 research plots. Proper intensive fertilisation of the beech seedlings affected positively both the initial height and growth. Even the slow-release fertiliser did not negatively influence the beech after planting. The health status of the beech is excellent after 4 years, the average height of plants with different fertilisation treatments having become equal. It is to conclude from the hitherto obtained results that a slow-release fertiliser in the substrate has a positive effect on the plant growth, and that different fertilisation variants did not cause any serious root deformations of the beech planting stock samples taken 4 years after planting. The impacts of prior nursery fertilisation upon the beech planted under the conditions of extreme sites are further investigated.

The degree is expressed by means of the stem necrotising index (ISN ), crowns necrotising index (ICN ), and whole tree necrotising index (INWT ). The values of the indices laid in the following limits: ISN 0.73-0.84%, ICN 0.12%-0.51%, and INWT 0.84%-0.90%. The current status of the beech necrotic disease in Southern Poland can be considered as favourable. The values of ISN recorded in Southern Poland were lower by 30% than the average ISN for whole Slovakia. We also recorded the frequency of selected insect pests (Bucculatrix ulmella Zeller, Cryptococcus fagi Bärensp., and Ectoedemia liebwerdella Zimm.), which act in the beech stands as vectors of the necrotic disease. With C. fagi, we recorded a high frequency reaching even 100%. In contrast, we did not at all observe the occurrence of B. ulmella and E. liebwerdella, which are common in the beech stands in Slovakia, as well as in Hungary, Romania, and Bulgaria. In the localities studied, we recorded the occurrence of two species of parasitic fungi of the genus Nectria (Fr.) Fr. causing the beech bark necrotic disease, viz. Nectria cosmariospora Ces et De Not. and N. galligena Bres. ex Strasser.

The plots capture various stages of conversion. Plots A, D, and H still possess structures nearing the forest of age classes. The assessment was made of the measurements taken in 1974, 1994, and 2004. Tree numbers on the partial control plots in the diameter degrees 10-70+ decreased in the first inventory period as compared with both the model situation and the initial situation in 1974 due to increased felling volumes in that period. The felling and the subsequent opening of stands resulted in a rapidly developing regeneration, which manifested itself by the increase in the number of trees in diameter degrees 2 and 6 above the values given by the model curve for these diameter degrees. In the second inventory period, tree numbers in these diameter degrees were lower by 11% as compared with the model situation and slightly lower as compared with the initial situation. Moreover, the results of the survey show that the forest stands under the selection system of management are massively invaded by broadleaved species, namely the beech and that danger exists that broadleaves will dominate in the future. This is generally considered undesirable because the quality of broadleaved stems in the stands under the selection system is low.

It introduces some methodological approaches to the field data collection (determination of tree heights by two-phase method, regression formulas for tree volumes and assortments of forest tree species, quantification of deadwood volume in sample plots) and biometrical models prepared for data processing and generalisation of the results. The design and conception of Slovak National Forest Inventory and Monitoring were set with the aim to enable providing complex and integrated information about the state and changes of production and ecological characteristics of the forest ecosystems.
