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.

Pěstebně-ekonomická analýza listnatých mlazin s různou příměsí dubu vzniklých kombinovanou a umělou obnovou
Zapletal, Miroslav
Abstract of the work This thesis deals with the growth characteristics of oak at the stage of coppice that was based in different variants depending on the type of mixing and method of recovery (combined, artificial). The research areas are located in Kostelec woods which is about 7 km from the Holešov town in the district of Kroměříž. In total there are five areas evaluated, the area (I, II) Option 1 - monoculture and area (III - V) Option 2 - mixed (combined and artificial regeneration). Crops were chosen so as they are the same age, only the area V is older and without silvicultural intervention. The measurement of tree species was carried out in each alternative on the pad of 3.14 m2 (r = 1 m) in a regular grid of 5x5 m. On each space were measured height, výčetní tloušťka a cenotické postavení of all trees and quality of the treetop. Collected data are recorded in tables and graphs. The results of the thesis show that the oaks in option (1) in all the above parameters are better than in the variant (2).
