    Opis:
    Paper discusses the influence of site quality on self−thinning process in silver birch stands growing on abandoned farmlands in Mazowieckie region (central Poland). Number of trees in a stand decreases with increasing age. The better the site (the higher site index value), the higher number of trees can be observed. However at the age of 10 difference between sites of various quality (site index) become insignificant. There is no need to include site index into the self−thinning models for young silver birch stands.

    Opis:
    Investigations were conducted on 48 Scots pines coming from 16 natural sites in northern Poland. This study was an attempt to analyse relationships between crown parameters of model trees and the stem conduction area in terms of site conditions, age and social diversification of the stand. Analyses showed that there is a strong dependency between crown volume and the volume and area of the xylem (sapwood) responsible for the conduction of water with minerals. Indexes of crown transpiration productivity analysed in the study seem to reflect reliably relations found in the forest phytocenoses and are confirmed in physiological dependencies between the transpiration apparatus, the vascular zone and tree height determined by the occupied social class in the forest community. It may be assumed that sapwood area (physiologically active) is characterised by the variable hydraulic conductivity, probably being the function of age and specific individual characters. In order to maintain the flow of transpiration, optimal for growth conditions, a tree as every living organism exhibits a certain adaptation ability, which makes it possible to meet the above conditions and cope with competition in the community.

    Opis:
    The correct assessment of the site conditions is the basis of the good management of forest areas. The aim of this study was to find a set of soil properties, which allow separating the diverse sites in terms of the soil productivity. We used 180 locations in the Carpathians and the Sudety Mountains for testing. The study plots were located in transects from the foothills to the top along the slopes, taking into account the variability of site conditions, geological substrate and exposition. The index was calculated on the basis of the content of <0.02 mm particles, the sum of exchangeable base cations, soil acidity and the ratio between total N content and organic C in the humus−mineral horizon. The soil trophic index for mountain areas (SIGg) that include the climatic factor was introduced. The factor is defined as the 650/altitude ratio for a given point above sea level. In the mountains, the content of <0.02 mm fraction, the sum of exchangeable base cations and soil acidity were determined in the column of 1 m² of the soil cross section and depth of 1 m (1 m³ of volume) due to the lower depth of the soil profile. The SIGg correctly separates soil of different productivity as the properties closely associated with the stable elements of the soil, expressing its production and properties, which reflect the current state of the soil environment, were used in the construction SIGg.

    Opis:
    In recent years, we face a massive dieback of Norway spruce stands in Poland. The cause of this process may lay in the way of their monocultural silviculture. The correct assessment of the habitat conditions and soil properties in particular is the basis of the proper management of these forest areas. The aim of this study was to verify application of the trophic soil index for mountain areas (SIGg) in the assessment of site conditions for spruce stands with different health condition. Three types of spruce stands were distinguished: degenerated, weakened and stable. In total, 32 study plots were established in following forest districts in southern Poland: Ustroń, Wisła, Bielsko, Węgierska Górka, Jeleśnia, Ujsoły and Lądek Zdrój. The SIGg was calculated on the basis of <0.02 mm fraction content, the sum of exchangeable base cations, soil acidity and the total content of N and organic C in the humus−mineral horizon. These attributes are useful to determine the potential productivity of the soils did not differentiate visibly the analyzed stand variants. The soil in degenerated and weakened spruce stands showed higher degree of acidity and less the content of base cations compared to soils of stable spruce stands. Mountain trophic soil index can be applied in the assessment of the forest sites potential. Although it does not enable to monitor the disturbances in the nutrients circulation, the detailed analysis of its components allows for precise assessment of the forest sites status.

    Opis:
    The numerical valorisation of soil quality is based on the determination of a set of soil properties adjusted to a given soil function in the ecosystem. The obtaining of an index is based on: determination of soil properties, their conversion into abstract numbers called indicators, index calculation and its practical application. The first proposal of a forest soil quality index was the Forest Soil Trophism Index – ITGL calculated for the soils presented in the Atlas of forest soils in Poland. The calculation of the ITGL was based on the following soil properties: percentage share of very fine sand and coarse silt fraction (Ø 0.1−0.02 mm) and silt and clay particles (Ø <0.02mm), reaction, sum of exchangeable bases and organic matter decomposition degree, content of skeletal parts. Its variability in the forest soils of Poland oscillates between 6.0 and 43.0 and its application in the valorisation of forest sites is multidirectional.

    Fertility of forest soils in the Bialskie and Złote Mountains is presented in the paper. Forest soil trophism indexes were calculated for mountain coniferous forest (BG), mountain mixed coniferous forest (BMG) and mountain mixed broadleaved forest (LMG). Modification because of the mountain conditions was applied to standard calculation of the index. Analyzed soils from BG sites represented oligotrophic group of soils, soils from BMG were classified as lower mesotrophic and from LMG as medium mesotrophic soils.
