The paper discusses the results of the research concerning the climatic conditions of the tree-ring growth of the beech, fir, spruce, larch and pine that constituted the stand in the Beskid Śląski, Wisła forest inspectorate, section 146b in the forest-district of Bukowiec. The stand, approximately 145 years old, grew at the altitude of 650—700 m above the sea level, on a steep slope, on the acid, brown soil of a strongly skeletal structure. On the basis of the dendrochronological analysis a strong relation between the tree-ring radial growth and the totals of atmospheric precipitation in the year preceding the growth and in the year of its appearance was found in all the species examined. This strong relationship between the cambium activity and the amount of precipitation (despite the favourable pluvial conditions of the region) was probably caused by the small ability of retaining and collecting water by the strongly skeletal soil present on the steep, mountain slope. Furthermore, it was found, that the tree-ring sire of such species as beech, fir and pine was negatively influenced by frosty winters. The high temperature during the growing season stimulated cambium activity of beech and fir, whereas it negatively affected the size of the tree-rings formed in spruce.
