Inventarizace výskytu jeřábu ptačího (Sorbus aucuparia L.) ve vybraných porostech Moravskoslezských Beskyd (revír Baraní)
 Kaděrka, Josef
This bachelor thesis is focused on the inventory of rowan (Sorbus aucuparia L.) in selected forest stands of the Moravian-Silesian Beskydy. The inventory was carried out in the bishop's forests of the Ostrava-Opava Diocese in the cadastral district of Bílá. The expanse of the inventory area is 191.58 hectares. Altogether 60 stands were inventoried in three departments. Sample plots were selected in each stand. Both rowan and maternal stand trees were counted and measured on individual plots. At the three selected plots, in addition to the height of the rowan, the diameter of the root collar was measured, the number of game damage was determined, and their age was identified in the laboratory. The obtained data were analyzed in Excel. The average number of rowans per hectare is 2854. In the height structure, most individuals are within 20 centimetres and 21 to 50 centimetres. In most stands, the percentage of spruce exceeded 50%. The average age of individuals from natural regeneration is 5.5 years and each individual has been on average 4.5 times damaged by game.

The presented research is focused on the state of natural regeneration (Norway spruce and Rowan), 10 years after total death of parent stands in the core untouched part Bavarian Forest National Park. The 16 permanent plots 40m x 40m are located on the southeast of Bavaria. We determined exact height, size of the last height increment, condition and species of trees. Number of saplings were counted and classified by heights. These number ranged from 53 to 17276 saplings per hectare. The spruce species composition was 96.7%. The height structure of spruce shows that almost 73% found spruce trees reached heights greater than 0.5 m. The average height increment increased with increasing height of saplings. This paper presents state of natural regeneration in mountain spruce forests in Bavarian Forest National Park without the human influence in summer 2010, 10 years after total death of parent stands.
