    Opis:
    The study examines the factors involved in the successful artificial regeneration of Norway spruce Picea abies (L.) Karst. by plantation or sowing in wood left behind in mountain forest stands. The issues studied are as follows: regeneration in stumps,trunks and disks (logs); regeneration in wood at various stages of decomposition; regeneration under the stand canopy and on clearings. The work brings a description of technological procedures to ensure success of this regeneration method.

    Opis:
    The author provides arguments for not using clear cuts in the mountains, limiting the large−scale shelterwood system and recommends the Swiss irregular shelterwood, and, under certain conditions, the shelterwood−group and irregular group−strip systems. He presents types of forest stands in the ownership of the State Forests Holding in Polish Carpathians (beech, fir, spruce, pine and alder forests), silvicultural objectives and felling systems favouring the attainment of these objectives.

    Opis:
    In the experiment eight populations of Picea abies were chosen at 100 m intervals between 500 m and 1200 m altitude a.s.l.. In each population wood core samples were collected from 14–19 trees (126 cores total), and measured using a Corim Maxi device. At four of the eight sites (every 200 m in elevation between 500 m and 1100 m a.s.l.), the diversity of ground vegetation was evaluated, and temperature was recorded at every 100 m of altitude. The highest average radial increment of spruce occurred between the altitudes 800–1000 m a.s.l., which is probably the optimum for spruce. The larger increment indices observed at higher altitudes may signify a high growth potential of spruce. It may also suggest a recent upward shift of the optimum growth zone for this tree species. In 15 phytosociological records, the presence of 148 plant species forming plant associations: Dentario glandulosae- Fagetum typicum (sub-mountainous and mountainous form) and Abieti-Piceetum, and community Abies alba-Rubus hirtus, was documented. No relationship was found between ground vegetation species diversity (expressed by Shannon-Wiener index) and levels of stand diversity. The vegetation species diversity varied with the elevation above sea level: the highest plant diversity was found at 500 m a.s.l., and decreased with increasing altitude. The potential increase in air temperatures may result in changes to the altitudinal range of many plant species including trees, and consequently in an upward shift of the boundaries of plant zones; in this case the sub-mountainous and lower mountainous forest zone. In this region, the optimal zone for Norway spruce may be restricted to the highest elevations.

    Opis:
    Since 1997, the experimental Potok Dupniański catchment in the Beskid Śląski Mountains (Wisła Forest District) has been an area subjected to intensive hydrological and hydrogeochemical research aimed at improving knowledge about the ecological growth conditions of one of the most valuable Norway spruce (Picea abies (L.) Karsten) ecotype – the Istebna spruce. Environmental conditions and comparison with the stands growing in similar environments in the 18th and 19th century in the Beskid Żywiecki region, as well as historical sources have shown that Istebna spruce is not a native provenance. Thus, the analysis of the state of forest management in the past times appears an important contribution to the above−mentioned earlier research. An increase in forest resources mainly resulting from the higher share of stands in older age classes and a decline in species diversity is a characteristic feature of the studied area. It is believed that the growing share of fir and beech in forest plantations as a consequence of underplanting would improve this situation.

    Opis:
    The aim of the study is to evaluate the selected methods and technological processes of wood harvesting used by Forest Service Enterprises and analyse the impact of the adopted solutions on the selected elements of the forest environment. The study is limited to a detailed analysis of the extent of damage to trees retained in stands caused by extraction during late thinning operations carried out under difficult mountain conditions. Analysed stands with pine as a dominant tree species (its percentage share exceeding 70%) aged 41−60 years and grew on the mountain forest habitat. Wood was harvested using the assortment method and skidded by the adapted farm tractors and specialized skidders, such as Kockums 812 and VFA.
