A total of 188 relevés were examined using stratified random sampling. A comparison was made between trends in vegetation variability throughout the entire locality and variability within the defined PNV units. The stratification of the locality according to PNV units was only partly representative of the main trends in vegetation variability, especially at ecologically distinctive sites. On the other hand, in areas with a relatively limited ecological gradient, the sites were "oversampled". The variability of plant communities within PNV units was high. The results of this case study suggest that the need for delineation of PNV units which are homogeneous in terms of production, site and phytocoenosis is overestimated. This delineation neither corresponds to the characteristics of actual ecosystems nor is necessary for the application of a PNV system. A more suitable unit for the development of such a system would be, for example, forest type series.

The variability of the fine root biomass calculated from 35 sample points represents approximately 90% of the mean value and reaches the highest value within the humus layer. The total fine root length investigated in 10 cm thick soil layers decreases with increasing soil depth. A significant linear relationship between the fine root length (calculated per 1 cm thick soil layer and 1 m2 of stand area) and the soil depth was confirmed, although the correlation is rather weak. The number of root tips decreases with increasing soil depth faster than the root length. As the number of tips per 1 cm of root length remains in the finest diameter class without significant changes, the reason is above all a decreased proportion of the finest root class (diameter up to 0.5 mm) from the total fine root length within the particular soil layer.

We carried out a detailed investigation aimed at differences between plantable bareroot and container plants of Norway spruce (Picea abies [L.] Karst.). Based on the results of this experiment, there exist marked differences in basic morphological traits between bareroot plants and plugs. The largest differences were observed in root collar diameter and root system volume. Differences in physiological quality (nutrient content, function of assimilatory organs) were also great. The results document that container seedlings of Norway spruce produced by intensive technology in controlled conditions of plastic greenhouses have very good predispositions for successful growth in difficult mountain conditions.

Data on the volume of salvage timber felling due to bark beetle infestation for the period 2002-2004 were used for the analysis. Research was carried out in the northwestern part of Slovakia. The techniques used were variogram modelling, Turning Bands Simulation and selected techniques of simulation post-processing. The maps indicating the probability that a critical volume of timber felling was exceeded in a particular location were produced. The proposed system may be used effectively for the improvement of pest control measures and development of slow the spread strategies. The benefits and shortcomings of this approach in forest protection are discussed.

Samp.) is an important broad-leaved tree spread in the Mediterranean basin. In Spain, few studies on the genetic variability of this species have been displayed. Storage seed proteins are a useful tool in the evaluation of the genetic variability of many species. The objective of this study was to analyze the usefulness of cotyledon proteins as markers of the genetic diversity in sweet holm oak. The evaluated populations were highly polymorphic for the glutelins, being detected up to 32 polymorphic bands with a wide distribution among all them. Considering all evaluated populations, about 35.8% of the total allelic variation was distributed among populations. This method of analysis of cotyledon storage proteins (glutelins) could be considered an additional tool for the evaluation of genetic diversity in this species.
