The paper presents an evaluation of the growth of newly established forest stands on former agricultural land and furthermore describes the state of the upper part of the soils in these stands in comp...
We have verified whether the temperatures in the zone of terminal leaders of saplings (+100 cm) were less extreme than the temperatures in the zone of terminal leaders of common-sized planting stock...
The behaviour of sika and red deer during the rutting season is highly variable in relation to vocalization, habitat preference during the rut, and onset and termination of rutting. The red deer is ...
Our research was concerned with a description of the influence of variability in average temperatures on the height growth of selected young populations of spruce in the Krkonoše Mts. Several pop...
Since 1994, the nutritional status and the air pollution load have been evaluated on 20 research plots, located in young Norway spruce stands in the ridge area of the Krušné hory Mts. The most re...
Organic nitrogen is an important but yet not very well explored component of nitrogen deposition. In this study concentrations and fluxes of organic and inorganic nitrogen in bulk precipitation in an ...
The article focuses on changes in soil chemistry observed on plots limed in 2000 in the western Ore Mts.(Krušné hory) on the basis of chemical analyses done before liming and repeated in 2002, 20...
The present paper describes the dynamics of changes in spruce stand disintegration in the Beskid Śląski and Żywiecki Mts. on the basis of the results of inventory performed in 2010 as c...

Forest ecosystems of the Krušné hory Mts. affected by long-term air pollution were finally disintegrated. The tree species composition has been changed in ecosystems disturbed in this way. Liming...
The main objective of this study was to investigate the causes of nutrient deficiency symptoms in Norway spruce (Picea abies [L.] Karst.) underplantings in the Hruby Jeseník Mts. In the area concerned...
Bareroot and containerized seedlings (seedling type) of Norway spruce, Scots pine, European larch, European beech, and sycamore maple were outplanted in autumn 2008 and in spring 2009. Roots of a half...
Natural mixed beech-fir forests were quite widely replaced by spruce dominated stands in Slovakia. Given the demands on the assessment of the forest status as well as on stopping the biodiversity loss...
Surface ozone is considered to be a very phytotoxic gaseous air pollutant. Its negative impacts at both the cell and the organ level have been shown, mainly as a result of experiments. However, the de...
The plateau of the Krušné hory Mts. belongs to areas that suffered the greatest damage caused by air-pollution stresses in Europe. A part of cultural practices aimed at the reconstruction of loca...
