The research was done in six forest districts in the Beskidy Mts. The area of spruce stands in degrees of threat of disintegration on the day of 30th September in the research period was determined for forest districts Bielsko, Ustroń, Wisła, Węgierska Górka, Jeleśnia and Ujsoły, on the basis of data in the State Forests Electronic Database (SILP) in degrees of threat of stand disintegration as well as in climate and vegetation zones. A comparison of the results of inventory of the stands threatened with disintegration in six forest districts in 2007 (altogether 24,446 ha) and in 2010 (altogether 16,886 ha) indicates a decrease in the rate of spruce stand disintegration. This may point to the slowing down of the rate of spruce stand disintegration as well as to considerable intensification of reconstruction work.

The elemental time study method was used to evaluate the system productivity. The productivity, cost, biomass yield, remaining slash, chip quality (size classification and energy content), and fuel and energy consumption were analysed. Chipping extracted small logs at the roadside yielded a productivity of 43.88 GMt.PMH0-1 (19.4 BDT.PMH0-1). The average cost was about 16.96 USD.GMt-1 (38.36 USD.BDT-1).

In this paper, we present the results of field infiltration measurements at the location of various vegetation covers, together with an estimation of the infiltration characteristics of a small mountain forest catchment. Measured steady infiltration rate values were extrapolated on the basis of the dominant plant species distribution in the catchment. We determined which plant species are dominant, and infiltration tests were carried out where these species were located in selected sites in the catchment. The characteristic steady infiltration rates were averaged for each dominant vegetation species. The percentages of dominant plant species were determined for established points placed in a regular network throughout the basin. An extrapolation of the directly measured infiltration values to these established points was calculated using (1) percentages of the dominant plant species determined at these points, and (2) characteristic infiltration rates averaged for these species. An infiltration map was created from the infiltration values calculated for the established points.

Purchart Title: Relationship between rodent density, environmental factors and tree damage caused by rodent species Abstract: The impact of rodent bark gnawing on common beech plantations was studied in the area of the Jeseníky Mts. in the course of four years. The extent of damage fluctuated significantly on 18 monitored plantations and was affected by a set of environmental factors, particularly by the altitude and herb layer character, which had a significant impact on the abundance and distribution of rodents. The ratio of grasses increased with decreasing altitude and conditioned the increasing abundance and occurrence of the field vole (Microtus agrestis), which proved to be the major pest in the area. Its impact was substantially more intensive (P < 0.05) than that of the more abundant bank vole (Myodes glareolus), whose abundance increased with increasing altitude, conditioned by higher numbers of its preferred dicotyledonous plants. However, the relation between an increase in abundance and the degree of damage was not significant in this species, unlike in the former. Although the damage of tree seedlings, caused by small rodents, can locally be serious, generally they do not generate an important impact on forest regeneration in mountainous regions.

The model catchment of the Hucava mountain stream is located in the Polana Protected Landscape Area - Biosphere Reserve, situated in the central part of Slovakia. The assessment of overall susceptibility of the model area to flooding is based on the multi-criteria evaluation of environmental factors, which crucially affect the hydrological cycle. These are represented by the geology, soil types, slope, forest type group, degree of ecological stability, exploitation of non-forest landscape and potential runoff in the model area. The methodology is based on the synthesis and subsequent processing of data in the GIS environment. The result is represented by the specification of categories (degrees of flood risk) to classify the model area to five degrees of overall susceptibility to flood as well as by the creation of maps representing the spatial distribution of different categories in the Hucava catchment.

Several published papers demonstrate that integration of shelterbelts with agroecosystems offers positive outcomes, such as better yield, more congenial microclimate, and greater organic matter levels. Nonetheless, soil biological diversity, the driver of greater organic matter levels, has not been convincingly tested and verified yet. In addressing this gap, we measured abundance and diversity of populations of arthropods and fungi in three11-year old shelterbelts integrated with pasture to determine whether a correlation exists between the abundance of and diversity in populations of arthropods and fungi in two seasons: late autumn-early winter (May-June 2011) and late winter-early spring (August-September 2011). Litter from the soil surface and soil from two depths were sampled at increasing distance from the midpoint of shelterbelts for the extraction of arthropods and isolation culturing of fungi. The relationship among distance, depth and biodiversity of different groups of arthropods and fungi was analysed using linear regression. We found that over both seasons arthropod abundance in the litter and soil declined with increasing distance from the midpoint of the shelterbelts, and with soil depth. However, fungi abundance in either season was not affected by proximity to the shelterbelt but increased with greater soil depth. Distance from the shelterbelt midpoints did not bear an impact on the diversity richness of both arthropods and fungi.
