Návrh managementu porostů v převodu na výběrný les na ŠLP Křtiny s využitím růstového simulátoru
Straka, Prokop
On the selected area in the localities of Pokojná hora and Klepačov on the school forest company Křtiny, which are in a stage of conversion to a selection forest there was collected dendrometric data by using the measuring kit Field-Map. This data was consequently processed in the growth simulator SIBYLA, and the scenarios of the growth of the individual sample areas were created. The results of the simulations were then compared in the application STATISTICA 12. As the most suitable concept was selected the one that was closest to the ideal selection forest. It was ascertained that for the stand 109 Cav the best scenario is the Mayer frequency curve type D. For the stand 114 Cav the most suitable concept was found to be the target thickness method.
Využití biometrie synuzie dřevin dospělých smrko-bukových porostů k lesnicko-typologické charakteristice jednotek polesí Štoky
Straka, Prokop
Biometric measurements were performed on randomly selected areas, using the ArcMap application in communal forests of Štoky, supplemented with typological and pedological characteristics of the measured areas. Using the Statistica program, the dependence of the microrelief on the height and dominant heights of the stand were compared. The collected statistical data were subsequently evaluated. It was found that only 2 species of wood species are present in the measured areas, namely Norway spruce (Picea abies) and European beech (Fagus sylvatica). Trees have the highest elevation in the leading habitats, and in the middle slope gradients. European beech reaches the highest altitudes on the southern exposition in the measured area, Norway spruce on the western exposition. Furthermore, trees reach the highest heights on wet forest types.
