Obnovní experiment na kalamitní holině - Rakovec I (ŠLP Křtiny)
Schramm, Daniel
The aim of the thesis was to evaluate the success and cost evaluation experiment of regeneration of forest in the area named Rakovec I (ŠLP) For this purpose, was established 5 different types of forest regeneration on the clearing area on an area of 0.15 hectares. This area was formed after the wind calamity in mostly unoriginal spruce forest. Monitoring was conducted on this area from spring 2013 to autumn 2015. The "A" variant simulates re-growth using sowing of an alder (Alnus glutinosa (L.) Gaertn) into a manually pre-prepared soil. The variant "B" represents the re-growth of forest by using a broadcast sowing of a birch (Betula pendula Roth.). The variant "C" represents the re-growth through sowing an alder (Alnus glutinosa (L.) Gaertn) and a birch (Betula pendula Roth.), into a mechanickly pre-prepared soil. The variants "D" and "E" simulate re-growth using bare root plant, planted by dibble level planting. For the variant "D" is selected a tree species alder (Alnus glutinosa (L.) Gaertn), and for the variant "E" isselected a spruce (Picea abies (L.) Karsten). According to an economic standpoint it is the least expensive a variant "B" (13,508.37 CZK/ha), in which is the only expense the purchase of seeds and subsequent sowing. Conversely, the most expensive variant is a variant of "E" (81,270 CZK/ha). Highest success of forest regeneration is a variant of "D", when from a total count of 93 pieces of seedlings in the autumn of 2015 was on the area a count of 90 pieces of viable individualsThe lowest succed of forest regeneration is in the variant "C", in which was found in the autumn of 2014 only 22 pieces of viable individuals on an area of 0.021 hectares.
