The purpose of this study was to determine the basic physico-chemical properties of soil in silver fir stands with different stage of natural regeneration. The investigations were carried out in south-west part of Poland – in the Sudety Mountains. From 854 silver fir stands, 40 testing sites, varying in terms of habitat conditions and degree of natural regeneration, were selected. Soil samples were collected from litter (organic horizon – O) with a thickness of 7–15 cm and from mineral A horizon lying up to 20 cm below the organic horizon and were then analysed for pH, EC, C org., total N, exchangeable cations (Ca, Mg, K, Na, H and Al), soluble Mn, Fe, Zn and Pb as well as particle size distribution (samples from A horizon). The analysed soil samples are characterized by very high acidity and low content of bases. According to the performed statistical tests, none of the factors analysed within the samples tested has a significant impact on the natural regeneration of silver fir. The only dependence between potassium content in soil and the regeneration of silver fir in the Sudety Mountains is close to statistically significance.

Data from floristic publications, forest management records, comprehensive questionnaires and original field research were used to assess the silver fir resources in the Sudety Mts. Fir trees older than 50 years were recorded in over 2000 localities but the mean number of individuals per locality was only about 15. The generally low number of fir trees and their considerable dispersion are the major causes of the poor reproduction of the studied species in the Sudety Mts. In that region, silver fir should receive special treatment and, if possible, excluded from logging plans. Current and projected activities concerned with fir protection are described briefly.

The available phytosociological literature were reviewed and compared with 12 original relevés made on representative of habitats of fir trees in the study area. Only in the eastern part of the Sudety Mts. silver-fir is still important forest tree. It is found most frequently in potential sites of acidophilic beech forest, which vegetation is now strongly transformed because of planting them with spruce. Typical, mainly acidophilic beech forest takes second place (in respect of frequent occurrence). Oak-hornbeam forest take third position.

In the 40 fir localities in the Sudety Mountains, varying in site conditions and the degree of natural regeneration development were taken soil samples from the mineral horizon and were subjected to particle size distribution analysis. The best regeneration of fir stands has been reported on medium-textured soils, containing a few percents of the clay fraction and from 50to 60% of sand.The poorest regeneration was reported on silty soils, located in the lower parts of slopes. In comparision with the Carpathians, spectrum of conditions in which firs grow in the Sudety Mountains is clearly shifted from coarse-textured soils to medium-textured soils.

In this paper, is presented data on the abundance and age structure of natural regeneration of silver fir in permanent plots in Sudety Mts. In the studied plots the abundance of fir seedlings is usually markedly lower than in the well-regenerating Carpathian forest stands. The major reason for this is the lower contribution of fir trees to forest stands in the Sudety Mts. as compared with the Carpathians. In most plots the process of regeneration is long and extended over many years. Largest numbers of seedlings developed in years of good fir cone crops. An important role in the process of natural regeneration of Abies alba in the Sudety Mts. are played by type of site, kind of humus and herb layer density. Most of the studied forest stands in the Sudety are not dense, so the herb layer is well-developed, that strongly restrain fir regeneration especially in fartile soils.

One-year-old needles from 20 silver fir trees in the Tisovik Reserve (Belarus) were characterized in respect to 12 morphological and anatomical traits, and the data were analyzed statistically to determine variability between trees. Individuals within the population generally were homogenous for those traits. Needle length was the most variable trait within the studied population. The width/height ratio of the hypodermic cell exerted the weakest differentiating effect between trees. The results indicated that the Tisovik Reserve population is weakly differentiated.

Until recently, the level of industrial air pollution in the Sudetes (a mountain range extending on the Czech Republic and Poland border) was very high.This caused a large-scale forest decline, especially in the western part of the Polish Sudetes: in the Izerskie and Karkonosze Mts. An analysis of data on fir defoliation in that area, collected directly after the period of heavy industrial pollution, showed a clear dependence of the degree of defoliation of the primary crown on canopy density: the lower the density, the higher the degree of defoliation.

The Sudeten Mountains are a region where the level of industrial air pollution is high due to brown coal combustion, but now the impact of pollution on the environment has greatly decreased. In this paper we attempted to determine how this fact affected the condition of silver fir trees. Our conclusions are based mainly on measurements of trunk diameter increments of 250 fir trees representing 42 populations of this species in different parts of the Sudeten. The main conclusion is that silver fir, at least to the age of 130 years, has the ability to endure unfavourable conditions and can substantially increase its growth rate in association with air quality improvement.
