The paper presents the results of the research on Bryoria capillaris (Ach.) Brodo & D. Hawksw. in the Polish part of the Białowieża Forest. Two new sites of this species have been found in the managed Białowieża Forest, in Władysław Szafer Reserve. Bryoria capillaris grows on the bark and small branches of Quercus robur and Picea abies.

The aim of the investigations was determination the reasons of dying down of needles and branches of common yew (Taxus baccata L.) in the park collection of Botanic Garden of Jagiellonian University in Cracow. The disease changes of infectious nature were observed on the examined plants’ parts. The changes’appearance, its location and extent were described in details. At fi rst the spots were brown colour with distinct hem. Then the needle and branch tissues were dying down. From end of May to July mass falling down of infesteted needles was observed. Mycological analysis of diseased tissues showed 34 fungi species. To the dominant species belonged: Alternaria alternata, Colletotrichum gloeosporioides, Fusarium spp., Pestalotiopsis guepinii, Phomopsis juniperivora and Zythiostroma pinastri. Common yew pathogens: Phomopsis juniperivora and Sclerophoma pityophila were found among the isolated fungi.

Modern forestry management should be based on the principle of sustainability.In order to preserve habitat productivity, the amount of nutrients removed from the environment along with forestry products must be taken into consideration. This study shows the exact concentrations of chemical elements in different tree parts of Scots pine, growing on poor soils in north-western Poland. The observedvalues were compared to the values found in literature. In addition, the relationship between the concentrations of elements and stem diameter or stand density was researched. The highest concentration of chemical elements was observed in the needles (C, N, P, K, Mg, S, Mn, Na, Fe) and the lowest (C, N, P, S, Cu, Na, Ni, Pb, Zn, Fe) in the stem wood. Most of the macronutrients (P, K, Ca, Mg and S) reached optimal values, with the exception of N showing a deficiency, especially in the needles. The relationship between the content of elements and DBH or stand density was rather weak, and in both cases, negative.

Thirty-three type A strains of G. abietina from diseased shoots or needles of P. sylvestris, P. nigra and P. armandii and three strains of Brunchorstia pinea var. cembrae from P. mugo were isolated from four regions of Poland differing with respect to climatic conditions. Genetic polymorphism of the mitochondrial small subunit rRNA (mtSSU rRNA), ribosomal RNA fragment including ITS1, 5.8S and ITS2 and glyceraldehyde phosphate dehydrogenase (GPD) gene was examined by the PCR-RFLP method. Genetic distance was ascertained with respect to B. pinea var. cembrae strains from G. abietina isolated from the examinedpine species (average Nei coefficient 0.137). The smallest genetic distance occurred between the strain groups of G. abietina isolated from P. nigra and P. armandii (0.059) and P. nigra and P. sylvestris (0.061), whereas the highest occurred between the groups of strains deriving from P. armandii and P. sylvestris (0.096). The impact of geographic distance on genetic distance between groups of strains from individual regions has been shown. G. abietina strains originating from mountainous areas were more distanced genetically (on average 0.031) from populations from other regions (Nei genetic distance 0.023). The main factors influencing genetic differences of the pathogen were specificity with respect to the species of the host plant and climate conditions, whereas geographic distance had lesser significance.

According to the research carried out in 1998-2000 it was found that small particles of the shoots left in the orchard after pruning are the place of the numerous fungi development. It was observed that the greatest number of species appeared 12 months after winter pruning. The species colonising fragments of bark and wood included typical patogenic species, pathogens of weakness, and saprotrophs. Some of isolated species may in favourable conditions become the cause of bark and wood diseases as well as apple rot.

The use of Bacillus thuringiensis (Bt) to control insect pests has already been established in various agronomic and forest crops. It is a bacterium that does not pollute the environment, is safe for mammals and vertebrates, lacks toxicity to plants and specifically targets insects. To date in-depth studies have not been conducted about the use of Bt to control the main pest of mahogany (Swietenia macrophylla King) and other Meliaceae species, the Hypsipyla grandella Zeller (Lepidoptera: Pyralidae). Therefore, this study aimed to test the pathogenicity of Bt strains on H. grandella caterpillars, as well to determine the lethal concentration required to kill 50% of the population (LC50) of the most promising strains. Ten strains of Bt toxic to lepidopteran proven in previous trials were used and these were incorporated into a natural diet with mahogany seeds to check their mortality. The LC50 of the top five strains was determined. The results indicate that H. grandella is highly susceptible to Bt toxins and the S1905 strain is highly toxic. Therefore, the use of Bt strains may be a tool to be incorporated into the integrated management of this important pest.

Field studies were carried out on 12 sample plots established in selected pure European fir stands, or stands with predominance of this tree species, in Lesko Forest District (Krosno Forest Region) and Krynica Experimental Forests. In total 200 fir tree-tops (100 in Lesko and 100 in Krynica) were analyzed. All tree-tops were infested by cambio- and xylophagous insects (Cerambycidae - 4 species, Curculionidae - 4, Melandryidae - 1, Siricidae - 1). The mean number of brood galleries per single tree-top was 76 (minimum 5, maximum 245). Cryphalus piceae and Pityphthorus pityographus were characterized by the highest mean indexes of dominance, frequency, and dominance structure. In Lesko Forest District 15 different insect associations (composed of 2-4 species) were found on tree-tops analyzed during this study. The association composed of Cryphalus piceae and Pityophthorus pityographus occurred most frequently (61.5%). It was found that the occurrence of brood galleries of some species depended on the diameter of a tree-top 0.5 m section, and the bark thickness.

On the basis of cone traits, three groups of Scots pine populations: lowland (N), mountain (C) and fool-hill (P) were distinguished in the Carpathian Mts, and the Sudety Mts. (Skrzyszewski 2001b). The aim of the study was to determinate the morphological and increment traits of population groups, which were of the highest discriminating power in interpopulational comparison regardless of group division based on cone morphology. The traits related to high quality of stem (tree height, short and narrow crowns with fine branches which fall off the stem quicker, less slenderness of stem and thinner bark) are more characteristic for the foothill pine and less for mountain pine. Pines of those populations form narrower annual D.B.H. increment in the same periods of life. Lowland pine (N) is characterized by the largest diameter increment and the largest differentiation of studied trails, and probably by the greatest plasticity. Regardless of the stand division done on the basis of cone morphology, stem and crown traits, which are crucial for production value, are of the highest discriminating power. The studies indicate that environmental factor is more significant than factor of origin. From the quality point of view, the foot-hill pines are marked by the best silvicultural traits.
