	Effect of coniferous monoculture plantation on plant species dversity Němeček, Jakub ; Vojta, Jaroslav (advisor) ; Douda, Jan (referee) A structure and a function of a monoculture woodland is diferent from the natural woodland condition. This is an influence of a herb layer diversity. The change of the herb layer are mainly distinguishable in the case of tree coniferous monoculture. They are the poorest at all of them viewpoint diverzity. The diversity of the woodland was analysed with an insuffiently consequence. This study get the knowledge about the species composition and the diversity of these monoculture. At the same time get the knowlege about next factores, which change diversity and species composition of stand. As a confirmation of this, coniferous monoculture are numerously and species-compositionally diferent from broadleave monoculture. And more, coniferous trees change the enviroment's condition and the whole biotopes. There are not depend any species of the herb layer at the coniferous monoculture on this studied site of Křivoklátsko. Detailed record
	Entry to reconstruction of potential natural vegetation of forest fragments in Českomoravská vrchovina highlands Halas, Petr The biodiversity and the forest vegetation structure are important instruments for the reconstruction of the potential nature landscape situation. One of the basis to explain actual biodivesity may be an attempt to the reconstruction of the potential nature vegetation of the forest fragments. Landscape history, methods of the forest and agricultural management are very important. The actual biodiversity of the forest fragments need not respond to abiotic conditions only but also to the changes of whole landscape. Detailed record
	Geobiocenological questions about (re)construction of natural vegatation with significant participation of oaks (Quercus sp.) Žárník, M. ; Holuša, O. ; Boublík, Karel Recent occurrence of oaks in forest ecosystems does not correlate with those in a potential natural vegetation. It causes the problems in reconstruction vegetation mapping. Assumed proportion of oaks in recent geobotanical and forest-site maps are probably overestimated. Detailed record
