Stav a vývoj obnovy lesa na majetku „Ostravské městské lesy“
Adamov, Jan
The subject of this thesis is to evaluate the development of rehabilitation and urban forests majetcích Ostrava sro most represented economic file is 6446 (beech farm nutrient habitats center position). The main tree species are spruce and oak. The vast majority of recovery occurs artificial regeneration. Natural regeneration is there a minimum share. Of the total area of 1,101.68 hectares of vegetation were over 10 years of renewed 254.78 hectares of forest, which is 23.10% of the total forest area under the administration of the Ostrava urban forests. In the period 2004 - 2013 was only natural regeneration registered in 2009 and 0.18 hectares in 2013, 1.2 hectares. During this period, the restoration performed on deciduous trees 147.17 hectares and 38.59 hectares of coniferous trees. Field investigation dealt with the silver fir. Crops with the representation of this species were monitored Fruiting fir stands, the status of young stands of fir and fir sowing. Prerequisity for successful recovery and cultivation of fir on property is nedeed for the cultivation of existing vegetation and protection against animals.

Vliv rozdílných způsobů obnovy jedle bělokoré na její odrůstání a vitalitu sedm let po výsadbě
Macek, Jiří
The goal of the work was to find out, what influence different ways of regeneration of silver fir have on its growth speed and overall vitality seven years after plantin. Study was carried out on research area ÚZPL -- LS LČR Svitavy, district of Radiměř. The fir was planted on area partially covered by forest wall, in v gab, with simultaneous planting of fir and larch. There was total of 7 research plots located on acidic stands between 4th and 5th LVS (forest vegetation grade) and variables measured were: losses, height, terminal growth of particular years, width of root collar, total number, length and width of branches, length of needles, colour of needles, shape of crown and trunk, frost and other damage. Results show, that different manners of planting (cover) do have an measurable influence on growth rate and vitality of silver fir. The best results were reached on area partially covered from multiple sides by standing forest and in gab, where frost damage was minimal.

Inventarizace a management jedle (Abies alba Mil.) na LS Jablunkov
Jaroš, Rostislav
The thesis provides an assessment of the status of European silver fir (Abies alba Mill.) in terms of its growth potential in view of the varying environmental features of particular habitat sites. To that end, sites were selected in Písek territory within the forest district of Jablunkov. The variance range in habitat site parameters and their impact on tree growth were monitored and analysed, including the relation to their age. The assessment criteria consisted primarily in field measurements of certain dendrometric parameters of selected tree, supplemented with additional data such as tree defoliation and fructification. The data collected are compared in the thesis with analogical parameter measurements made in tree clusters for Norway spruce (Picea abies (L.) H. Karst) occurring alongside the silver fir. The thesis also notes the ability and intensity of natural regeneration of silver fir and its possible impairment.
