This diploma thesis evaluates the commencement of phenophases considering the changing microclimate conditions in the habitat of Norway spruce (Picea abies /L./ Karst) in a young and a mature spruce monoculture at the ecosystem station Rájec. The phenology of spruce undergrowth has also been under observation. Regarding the methods, above-ground phenology and observation by means of phenocams have been used. The results have been compared not only among themselves but also in the context of long-term averages. Thanks to the fact that phenophases of forest woody plants and herbaceous plants are dependent on climate conditions, the results of long-term phenological observations are a conclusive indicator of climate changes. The results of this diploma thesis can be a contribution to the phenology database.

The aim of this work was to find out how different planting biotechnique of the seed and different site have an impact on growth of container-grown planting material. It was planted norway spruce, european beech and sessile oak on SLT (czech typology system) 5K and 5G. Spruce and beech was planted with five different types of seedlings and oak with three different types. The influence of root ball overlap during planting was also investigated. Measurements took place in 2016, 2017 and 2018. In particular, the following parameters were investigated: the length of the aerial part, the increment, the thickness of the root neck, the length and width of the assimilation organs, the vitality, number of roots rooted in the root ball and the losses. The results show that, the growth of the container-grown planting material is influenced by different biotechnology of seedlings and sites. Planted plants grew better at 5K than at 5G. Best for norway spruce was planting cutter biotechnique for both sites. Best for european beech was center hole planting biotechnique, eventually planting thorn biotechnique. Best for sessisle oak was center hole planting biotechnique. The root pack is better to overlap with a layer of soil during planting.

The aim of the thesis was to compare and evaluate the growth of bare-rooted and rooted seedlings of the same tree species based on the findings. All trees compared and monitored in this work were planted in the same area of the cane, in 2016. The evaluation was carried out on 4 research areas, these areas are characterized by sets of forest types 2S (fresh beech oak), 6K (sour spruce beech), 6S (fresh spruce beech) and 7K (acid beech spruce). There are three species of woody species in these areas, namely Norway spruce (Picea abies (L.) Karst.), Douglas fir (Pseudotsuga menziesii (Mirb) Franco) and European beech (Fagus silvatica L.). On each plot, 100 individuals were subjected to measurement for each variant of planting material in the autumn of 2017, for which the following parameters were evaluated: losses, height of the overground part in 2016 (which was measured after the scar marking the last increment), height of the above ground part in 2017, increment in 2017, the length of branch growth in 2017, the width of the crown, the thickness of the root neck, the trunk deflection from the vertical axis, the length and width of the assimilation apparatus, the straightness of the stem, the vitality of the plant. Based on the results, the following conclusions were drawn: On the SLT 6K surface in the case of woody beech, the variant of planting material grew better. In contrast, barkless planting stock grew better in Douglas fir tree species. The Norway spruce tree then grew better in the rooted variant. In the overall assessment of the abovementioned factors, it can be stated that on the SLT 6K the rooted seedlings grow better. In the SLT 6S area, the species of beech was found to be better growing in the bare-root variant. The Douglas fir also grew better in the bare-rooted variant and Norway spruce was best grown in the rooted roots variant. The result is that the bare-rooted planting material grows better on SLT 6S. On the area of SLT 7K there was a better growth of the beech in the rooted variant, as well as the better overall results of the spruce in the openrooted variant. Douglas fir grew better on the area in the barefoot variant. To summarize the findings of the observation on SLT 7K, it can be stated that the better results are achieved and hence the growing of the rooted planting material. In the SLT 2S area, the results for the growth of beech wood were better in the bare-rooted variant; Douglas fir tree has not been evaluated for this area due to insufficient seedlings when setting up the research area.

The aim of this Master thesis was to assess the survival and growing out of container planting stock for the Norway spruce (Picea abies (L.) Karst) and the European beech (Fagus sylvatica L.) after the set period of stressing by dessication due to incorrect manipulation. The plants exposed to desiccation for 2, 3, 4 and 5 days were planted in a research area. During the first day of testing, the variant for checking of unstressed planting stock was planted. The research also included the testing of new methods for assessing root ball water loss during plant desiccation. The method for measuring the decrease in weight of a root ball during manipulation was used and two devices for measure moisture levels in root balls were tested (HH2 and WHT 860). The first assessment was carried out five weeks after planting out, during which vitality and sprouting progress were assessed. The second assessment took place at the end of the vegetation period, and vitality, duration of apical increment, thickness of the rootcollar and the length of needles and leaves were assessed. It was confirmed that with an increased duration of root ball desiccation comes the loss of moisture which after a certain period of time negatively impacted the survival and growing out of the tested plants. The limit for the root ball was a 3-day-long exposure of the planting stock to desiccation. The spruce planting stock is significantly more resistant to the negative effects of radiation and desiccation than the beech planting stock. The minimal threshold for moisture levels was set, determining when the planting stock can grow out without any major problems. The tested methods appear to be promising and can be used to assess the planting stock quality before the planting.

The aim of this work is to analyze data on the damage caused by game from the database Field-Map program of operational statistical inventory. This inventory was carried out in 280 inventory plots to forestry section Borky school forest enterprise Masaryk forest Křtiny, in 2003, 2008 and 2013. Another aim is a suggest a method and a method of long-term monitoring of game damage to forests. Information on damage by game were evaluate in the relevant graphs in relation to the type of stand (coniferous, broadleaf and mixture) edaphic categories and game evidence (above game hunting). Next, the data were compared based on the general linear models in statistics. At principal species and accessory species in relation to the growth was the considerable increase by game damage. Data of game damage depending on edaphic categories showed the greatest harm to the ecological variety of nutrients. After the use of SPI in this work (the evaluation) and keep to relenvat principle of this system, this method was recommend as flexible method for long-term monitoring of the development of game damage to LÚ Borky.

An afforestation of agricultural lands in the Czech Republic has a long tradition. In the future, a few thousands of hectares of agricultural lands is considered to be afforested. The aim of this thesis is to research possibilities of fertilisation usage in process of agricultural lands afforestation within Natural forest area (NFA) 31 Českomoravské mezihoří. The research part of the thesis contains results of soil and nutrition analyses applied in Letovice-Kochov research area. The main goal of analyses was to find the impact of fertilisation on chemical soil characteristics, on nutrition of Norway spruce's needles (Picea abies (L.) Karsten), on the development of morphological quantity, and on the health of specimen. All of the characteristics are assessed in the context of climate in 2016. The positive effects of fertilisers were researched despite a low-humid year. The best effects were spotted at fertiliser SilvamixR30. To the results, SilvamixR30 fertilizer could be used in praxis, especially for agricultural lands afforested in named NFA.

This thesis examines the influence of microwave pretreatment of wood modification and Bethell impregnation methods on the treatability of Norway spruce (Picea abies) in consideration with its mechanical properties. The aim of this work was to establish the intake of impregnants (preservatives) and the depth of penetration in transverse direction of each treatment group with impregnated specimens. Further experimental examinations that were focused on the assessment of mechanical wood properties and the comparison with references (non-impregnated specimens) followed. Results showed that the intake of impregnants and the depth of penetration increases with time (modification) of the impregnation treatment. In contrast, microwave wood treatment actually decreases those values. Neither microwave modification nor adjustment of impregnation method had an influence on mechanical wood properties.

Coal is the most important raw material mined in our country. The mining acitivity creates huge impact on the landscape. The aim of the thesis is to compare the attachment of spruces on spoil tips created by coal mining and their growth during spontaneous succession and reclamation. The studied non-recultivated areas are overgrown with spontaneous vegetation consisting mainly of willow (Salix caprea), white birch (Betula pendula) and aspen poplar (Populus tremula L.). The reclaimed area only consists of planted Norway spruce (Picea abies). The density of localities, age and height structure, layout on terrain waves and distance from the edge of the dump were studied. Spruces were also mapped using GPS. The density of spruce vegetation on reclaimed areas is significantly higher than on succession, however, their growth is slower. On non-reclaimed areas, the growth of already attached spruces is significantly faster than on reclaimed areas. The results show a higher attachment of spruces on the slopes of the waves, especially on the northern leeward side, rather than in the troughs or on the peaks. The results show the possibility of undercutting succession areas with climax trees as a promising method of reclamation. Keywords: spruce, succession, reclamation, establishment of trees, density of trees

This thesis is a contribution to understanding of predisposition of solitary Norway spruce (Picea abies [L.] Karst.) to bark beetle (Ips typographus (L.)) attack. The predisposition is estimated from long term effects of multiple stress, which are determined by tree crown transformation. By virtue of created model, it was documented that some environmental variables could have considerable effect on tree crown transformation. Tree crown transformation is generally considered a mirror of spruce health status.

The effectiveness of countermeasures (pheromone traps or trap trees) and its combination in reliance with either spring or summer generation of spruce bark beetle in areas with differentiated calamitous base were surveyed in the summer of 2012--2014 in the district of Krasov, Forest Management of the town Albrechtice. During the spring swarm the combination with equal number of each countermeasure (50 TT /50 PT) seemed to be the most effective. In the summer swarm, the ratio with dominant number of trap trees (75 TT /25 PT) was more effective, closely followed by the ratio with dominant number of pheromone traps (25 TT /75 PT).
