Založení přípravného porostu na kalamitní holině plocha Rakovec II (ŠLP Křtiny)

The aim of this thesis was to evaluate the fruitfulness of the establishment of the preparative stand and to propose following suggestions for the forest restoration at the area Rakovec II (TFE). For this purpose has been at this research area analyzed the state and the development of the birch (Betula pendula Roth.) restoration by sowing and natural regeneration of all tree species at the clear-cut area, which was formed after the windthrow disaster in predominantly non-native spruce forest stand. On the larger part of the area (0.25 ha) it has been performed full-areal sowing of birch and remaining surface (0.125 ha) was left as a non-intervention area for control checking. Inventory control survey conducted on 100 blocks for the variation of sowing and on 50 blocks for control variant. There was additional inquiry to analyze the influence of substrate and soil preparation to initiation recovery survival. Monitoring took its course at the research area from spring 2013 to the autumn of the year 2014. While at the sowing area was the abundance of birch seedlings at the end of the experiment 261 pieces, on the control stand, it was only 6 pieces. From a total of 267 pieces of birch seedlings, the utter majority of them occurred on mineral soils -- 72 %. To evaluate the impact of subsequent land preparation for the restoration of birches, another monitoring is still needed. Limit of success of the preparative stand establishment by sowing the birch are suitable soil conditions. Soil preparation is also recommend, as a prerequisite for a successful restoration of birch trees at the area
