|Title: BIODIVERSITY OF FOREST PLANT COMMUNITIES WITHIN SPRUCE STANDS CONVERSION IN VEGETATION TIERS 4 AND 5|
|Author: JAN ŠTYKAR|
|Abstract: Transformation in the composition of forest stands was studied on plots with the following
arrangement in polygons: natural stands, converted stands and stands in conversion. The area of study is situated in the Novohradské hory Mts and Třeboňská pánev basin – Vegetation tiers 4 and 5. Vegetation occurring on the plots was described, structure of the communities was
analyzed in terms of its spatial, species and ecological composition and classified on the basis of its naturalness. Development of the moss layer appeared to be an important trait of the converted stands together with the typical change in species composition of undergrowth synusia at a level
of species and ecology.
Accumulation of coniferous litterfall and raw humus formation, as indicated by the high
coverage of terrestrial mosses and species contributing to the development of raw humus, represent phenomena typical for the cultivation of non-autochthonous (namely spruce) coniferous monocultures. Stands under conversion represent a succession link disrupting the negative processes and bringing the properties of the phytocoenoses and their abiotic environment back near to their natural status.
