Přirozená obnova listnatého lesa na exponovaných stanovištích VLS Lipník nad Bečvou
Pálka, Ondřej
The bachelor thesis deals with natural regeneration of deciduous forest at exposed sites in Czech military forests (division Lipník nad Bečvou), forest district Velký Újezd. The main goals of this study were to evaluate success of different-aged natural regeneration stands at different exposures (north, south, east, and west). In case of all analysed naturally regenerated stands, the Fagus sylvatica species is dominated, the Fraxinus excelsior, Tilia cordata, Acer pseudoplatanus, Acer platanoides are admixed species. Under parent stands, the highest natural regeneration density was detected at north exposure sites (222,500 piece/ha with the highest proportion of individuals in the height class of 1-20 cm). In two years naturally regenerated growths (in the open sites), the highest density of regenerated young individuals was detected at west exposure sites (115,000 piece/ha), with the highest proportion of regenerated individuals in 2 -- 3 meter height class. The characteristics of all investigated stands of natural regeneration fulfil the criteria for reforestation according to norm no. 139/2004 Sb. § 2. The results including analysis of different forest regeneration ways confirm that regeneration by border felling (width of 20 m), oriented along the slope (perpendicular to the contour) with regeneration period of 40 years is suitable silvicultural way for successful natural regeneration.
