Hodnocení stavu a vývoje přirozené obnovy na TVP “Smrk“ se zaměřením na habr obecný (Carpinus betulus L.) na polesí Vranov; ŠLP Masarykův les Křtiny

Hornbeam is a neglected and not very desirable tree species in our forests. Despite this, its representation in mixed and deciduous forests is increasing. This is mainly due to its excellent natural rejuvenation ability, its ability to adapt and grow in almost any habitat. This thesis deals with the assessment of the status and development of natural regeneration with a focus on hornbeam. The thesis also includes research conducted on permanent research plots ("Spruce", stand 69C9) established in the Vranov forest, Masaryk Forest Křtiny. Data measured using basic dendrometric parameters were compared. The beginning of the measurements is dated from 1958 to the present. In the results it was confirmed that hornbeam rejuvenates very well on these sites. Notwithstanding the presence of other tree species in the parent stand, the natural regeneration of hornbeam was considerably higher. It is a shade-tolerant tree species that does not show large increments in height or thickness. It holds its own in the lower echelons and thus helps to nurture target economic tree species.
Vliv výchovných zásahů na tloušťkový přírůst smrku

The aim of this thesis is to evaluate the influence of educational interventions on the thickness growth of Picea abies. Specifically, the effect of under-level and level thinning. To compare these two methods, a control plot was used where no intervention was performed. The effect was examined on three plots. The experimental plots are located in a forest cover established in the spring of 1978 on the ekosystém station Rájec (NFA 30 – Drahanská vrchovina). The survey was realized in 2012 – 2016. The evaluation of the influence of the educational interventions was performed using competition indices. By calculating individual competition indices, it was found that the competition index value affects the value of thickness and perimeter increment. For forestry practice, it follows that the right education can guide the competition value index and thus the thickness and perimeter increment.
