In the Czech Republic, mountain watersheds are mostly forested with dominant Norway spruce (Picea abies) plantations. The aim of this paper is to analyse changes in radial growth and xylem anatomy of Norway spruce trees in the upper plain of the Jizera Mountains, related to changes in climate (air temperature, precipitation), air pollution and acid atmospheric deposition. Data of two neighbouring climate stations were used to detect trends in air temperatures and precipitation. At elevations of 745–1060 m a.s.l., the ring-width growth was significantly affected by mean annual temperature, while impacts of elevation and precipitation were not significant. In the period 1975–1995, the detected drop in tree radial growth (ca 60% of the normal period, prior to the peak of acid atmospheric deposition) corresponded to the increase in atmospheric SO<sub>2</sub> concentrations and acid atmospheric deposition. The number of cells in tree rings decreased by ca 30–40% in comparison with the normal period, but the mean size of cells did not change significantly. In the last 20 years, increasing radial growth has been detected simultaneously with rising air temperature, and density of cells decreased by 30% in early wood, and by 10% in late wood, increasing the total number of cells in tree rings by ca 10% in comparison with the normal period. Integrated effects of climate and non-climate variables on the variation of tree radial growth in the Jizera Mountains reflected the legacy of acid atmospheric deposition in the forest ecosystem.

The preconditions for creating an exposition on the botanical and geographical site "Altai" of the Polar-Alpine Botanical Garden of the KSC RAS, represented by cenotic elements characteristic of the forests of the Altai mountains: dark-coniferous, light-coniferous and black taiga. Such expositions in botanical gardens are one of the forms of preserving the biodiversity of introduced plants ex situ. The condition, structure, species composition of the created plantings for this period - the completion of the first stage of work ("Creating a tree tier") is described. Preliminary results of plant introduction the main tree species ( Abies sibirica Ledeb., Picea obovata Ledeb., Larix sibirica Ledeb., Pinus sibirica Du Tour, Pinus sylvestris L., Tilia cordata Mill ., Populus tremula L.) forests of the Altai mountains. The condition of coniferous plants is characterized as normal: they show climate and soil resilience, have a natural rhythm of development here, go through all stages and phases of ontomorphogenesis. A comparative analysis of the rhythms of seasonal development of plants of herbaceous species characteristic of the most contrasting ecotypes of the Altai mountains (foothill and high-mountain) showed that the conditions of the Northern taiga of the Khibiny mountains of the Kola Peninsula are more consistent with plants of high-altitude habitats (high-mountain ecotype). Features of growth and development of plants of Altai species ex situ indicate successful adaptation of most of these species to the conditions of the Kola Arctic.
