Sudeteny Mts. are a region where the level of industrial air pollution was very high due to brown coal combustion. In this paper I presents the assessments concerning the fir stand quality class and crown vitality.The study were carried out between 1999 and 2001 and supplemented with studies made in 1997 and 2005. My conclusions are based on measurements of 3529 fir trees representing 481 populations of this species in different parts of the Sudety Mts. The stand quality class of the fir in the Sudety Mts. are better than expected but about 0,5 degree lower than in the Carpathians. Our results confirm the reports concerning the strong and very strong damage of fir crowns in the Sudety Mts. in the 1990’s. It was calculated that the average fir in the Sudety Mts. stands has a primary crown with a length that is approximately 19% of the total tree height and which is damaged in approximately 36%. At approximately 23% of the total height the average fir develops a regeneration crown. An additional factor which contributed to fir damage was their frequent presence in thinned stands. In these places the process of crown reconstruction from a wide to a denser is observed. In the recent years the level of industrial pollution in the Sudety Mts. has been strongly reduced. This particularly concerns sulphur oxides. This has contributed to the improvement of the crown health of the studied species, but the crown regeneration is slower than the trunk diameter increment. The crown damages have so far been proportional to the altitude. Trees which grow in stands located in lower areas have healthier crowns. Trees which grow in broken canopy and on hilltops are more vulnerable to the impact of pollution carried by wind and fog. The severe damage to the top parts of the crown has a negative effect on the cone crop of the fir.

Support of European beech (Fagus sylvatica L.) and sycamore maple (Acer pseudoplatanus L.) plantations by amelioration has been tested in air-polluted sites in the mountains since 1993. The research locality is a site with humic podzol soils at an altitude of 960 m a.s.l. Dolomitic limestone (1 kg per tree) was mixed with soil used for planting tree seedlings. According to the results of a 15-year investigation (1993– 2008), liming had a positive effect on beech tree growth, while the positive effect of liming on tree growth was temporary in the case of sycamores. Ca content was higher in the limed beech plantations throughout the observation period. Soil analyses (sampled in 2002) showed that the application of dolomitic limestone influenced soil conditions markedly in terms of increased pH. The pH values measured in H2O increased from 4.9 to 6.2 for beeches and from 4.3 to 6.1 for sycamores.

The study shows a high dynamics approximately five-year-old natural regeneration of silver birch (Betula pendula Roth) growing on the research plot located in the fertile mountain habitat in the middle of the lower montane forest zone in the Silesian Beskid Mountains (Beskid Śląski) compared to its co-occurring species. The dynamics is expressed as a significant annual increment in height and diameter of birch trees, leading in consequence to the appearance of an older sapling phase for most regenerations of this species. This creates the possibility of early undercanopy planting of tree species adjusted to the site conditions, mainly silver fir (Abies alba Mill.) and European beech (Fagus sylvatica L.).

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.

The purpose of the research was to study some of the features of silver birch, in its habitat conditions, as a naturally occurring pioneer crop appearing in open spaces formed by the disintegration of the Norway spruce monocultures in the Silesian Beskid Mountains. On the three research plots the occurrence of the young natural regeneration and understorey of 13 species of trees and shrubs was determined. On the basis of the number of specimens it was found that the most dominant species in the whole area was Norway spruce (56-64%). Birch accounted for 14-16%, and all pioneer species (Betula pendula, Populus tremula, Pinus sylvestris, Salix caprea, Sorbus aucuparia) accounted for 21-23%. However, the researched plots are generally covered by birch due to the share of this species amounts to nearly 90% in the height classes above 0.5 m. The birch appeared within 4-6 years of the disintegration period of the spruce stand. The succession of the birch, its quick growth and ability to develop a crown confirm the possibility of using this species as a pioneer crop. Climax species (silver fir and common beech) can be introduced to a seven-year-old birch pioneer crop, depending on the birch vitality, with the assumption of the conversion period of 30 to 40 years. In the case of the birch vitality abatement the suggested period of conversion will have to be shortened.
