AbstractFull Text

Structural characteristics of stands were evaluated on a data set comprising 10 plots dominated by young Silver fir and Norway spruce. Statistical tests and cluster analysis identified two major structural groupings, which were related to the stand age but not to the stand age pattern. All younger, ...

AbstractFull Text

Conifer plantations were established at the site in Vidlic, Mt. Stara Planina, Bulgaria, to reconstruct degraded beech stands and to compare the development of the species used at a beech site. Therefore, both domestic species (Scots pine (Pinus sylvestris), Austrian pine (Pinus nigra), and spruces ...

AbstractFull Text

The devitalizing process within the studied stand developed under frequent activity of adverse factors and adverse stand state, as consequence to intensive tree progress and inadequate tending. At the age of 42, approximately 75% of the overstand trees had irregularly grown and compressed crowns,...

AbstractFull Text

This paper aims to evaluate the present condition and expected development of soil acidification (Oligotrophic Cambisol) in a Norway spruce (Picea abies) monoculture located in the Drahanska Upland (Site 1) and in the Moravian-Silesian Beskids (Site 2), Czech Republic. Acification of forest soils...

AbstractFull Text

Growing spruce monocultures in Central Europe out of their natural range and clear-felling regeneration of these stands provoke interest of ecologists and foresters. The study was conducted in the region of the Drahanská vrchovina Uplands (the Rájec project), altitude 620, mean annual precipitation ...
