Potenciál využití sukcese při obnově kalamitní holiny
Květoň, Lukáš
The subject of this thesis was to analyse the success of forest regeneration on calamity clearcut incurred after wind calamity "Anthony". After decline of approximately 1,7 hectares of beech forest on rich stand, there was founded a permanent research area of size 15x110 m in 2012. On spot grid (5x5 m) was observed spontaneous development of woody and herbaceous vegetation. The outcome of the study was to evaluate the density of natural regeneration of two growing seasons. Under current legislation (Act 289/1995 Coll., Decree 139/2004 Coll.) can be regeneration evaluated as unsuccessful, mainly because of the low number of targeted tree species 7 779 pcs/ha, which do not reach limit of the minimum number of individuals per hectare. The density of other tree species amounted to only 476 pcs/ha. The following year, a decrease of targeted tree species density reached 7 619 pcs/ha and increase of other species density reached 952 pcs/ha. In the first year was recorded the highest density of beech (3 175 pcs/ha) and oak (2 222 pcs/ha), in the upcoming year these species showed the greatest decline. Very significant influence on the density of natural regeneration was distance from the edge of the surrounding forest, where up to 5 m from the edge of the stand density of natural regeneration reached 70 000 pcs/ha, over 45 m from the edge of the stand natural regeneration density did not reach more than 10 000 pcs/ha
