The present paper describes the dynamics of changes in spruce stand disintegration in the Beskid ¦l±ski and Żywiecki Mts. on the basis of the results of inventory performed in 2010 as compared to those in 2009. 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, Jele¶nia 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....

The Bruks mobile chipper was tested for chipping extracted non-merchantable stemwood at the roadside in Pine plantation in Victoria. 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).

Among other important factors, vegetation cover strongly affects the hydrological processes in mountain catchments. 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...

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...
An assessment of hucava mountain stream catchment susceptibility to flooding

The paper deals with an assessment of the Hucava mountain stream catchment susceptibility to flooding. 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...
Abundance and diversity of soil arthropods and fungi in shelterbelts integrated with pastures in the central tablelands of New South Wales, Australia

Shelterbelts are important for the sustainability of agriculture because they provide a variety of benefits to farmers and the society. 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...
