This bachelor thesis analyses three study objects which differ in site preparation and seedling protection. The treatments performed were as follows: 1) sowing, site preparation, stump removal, and seedling protection by fencing on the first site 2) sowing and seedling protection by fencing on the second site 3) sowing and seedling planting without seedling protection onthe third site. The main goal of the thesis was to evaluate the success of artificial regeneration by sowing. Within the sites 260 research plots of 1m2 in size were established, on which the general ecological and stand conditions were evaluated. Results show the best seeding success on the first object, where the site preparation was performed (45.750 trees/ha), followed by the second object (36.583 trees/ha), while the third object exhibited poor seeding success (7000 trees/ha). There were altogether 18 tree species presentamong the seedlings and saplings, with most frequent species being the Norway spruce and Scots pine. The results confirm negative influence of groundvegetation upon regeneration and negative influence of increasing distance from the seed tress upon the seeding success. Ground vegetation coverage was the highest on the third object (67 %) followed by 47 % coverage on the second object and the lowest (26 %) on the first object. The seedling density abruptly decreased at distances larger than 30 m form seed sources, while the lowest seedling densities in the direct proximity of the seed trees,remain unexplained. The cost comparison between sowing and seedling planting confirms that sowing is the favourable type of artificial regeneration in economic terms, whilst unsuitable for sites with southern exposition and abundant ground vegetation.
