The aim of this thesis was comparing growing of beech plants in different conditions under preparatory stands of alder and birch on LS LČR Šternberk district. There were 15 sites (8 under alder stand and 7 under birch stand) on which were made in different ways mining interventions in preparatory stands. There were measured overall 7 parametres (total height of seedlings, seedling height of last year, increment per the last year, length and width of the leaf, root collar diameter and deflection of stem from the vertical axis). Based on weight rating was find out, that each one of preparing stands has different impact to underplanted cultures. Under birch preparing stand was best conditions find out at site, where was density of stand reduced to 30 %. Under alder preparing stand was the best conditions find out under preparing stand with full density. The worst conditions for underplanted cultures were find out at sites without preparing stand (at clearcuts).

The diploma thesis deals with comparison of production of one-story and two-story pine stands on acid soils on 3rd vegetation belt. The thesis provides comparison between two different silvicultural methods for Scotch pine (Pinus sylvestris L.). The study area was located in central Bohemia, in the Forest Natural Area Křivoklátsko. Investigated forest stands belong to the military forests run by Vojenské lesy a statky, s.p., division Hořovice, forestry office Nouzov. Using circular sample plots the stock volume and mensuration characteristics were measured and calculated in individual stands. Evaluated characteristics of one-story and two-story stands were compared. The most important result of the research is the fact that Scotch pine (Pinus sylvestris L.) reaches higher production and higher timber quality in the two-story stands.

Extraction of mineral resources constituted the development of industrial companies worldwide. But it has a major impact on the landscape and environment. Restoration of areas disturbed by mining is current issue especially on large surfaces after surface mining. In the Sokolov region, the forest reclamation was carried out on the Antonin spoil bank in the years 1969-1972, where forest stands of different species composition were established under the same conditions. The aim of this work is to compare the mixed pine stands on anthropogenic soils more than 40 years after their foundation, to assess their suitability for reclamation and to describe the influence of admixed deciduous trees on the production and ecological potential of the site. On the plots the basic mensurational and production quantities of the stand were measured. The dendrochronological analysis was performed and the diameter increment was detected for the main species Scots pine. Based on the diameter increment, the tolerance analysis was carried out for the highest risk factor on these sites - drought. The most appropriate in local conditions seems to be a structure of pine stands with an admixture of lime trees, which is characterized by the highest production, soil formation and ecological potential. The work also points to two important factors that significantly influenced the silviculture on the Antonin spoil bank. It is the neglect of stand tending, and thus significant disruption in stand stability, and limiting intake of water, causing significant declines in increment regardless of an admixture or character of the stands.

The dissertation, The History of Evolution of the Forests of the Category I Protected Area in the National Park Šumava- environs of the municipality of Prášily, firstly focuses on the research and analysis of extant historical documents and other archival materials. In particular it analyses the historical maps of the former Velkostatek Prášily-Dlouhá Ves of the Schwarzenbergs family that show the evolution of the forests and their management between 1860 and 1930. Secondly, the dissertation focuses on the assessment of the current state of the forests and the way in which they are managed by the Správa NP Šumava and in particular on the positioning of the category I protected areas in order to protect the remnants of the native woodland.

Pastures and meadows are often looked over because of they are minor yields against arable land. Because of it it is common to not care so much about them. The purpose of this research is to compare several ways of care about this pastures (number of grazing animals, manuring) concurrently grazing and find out if it is economically expedient to invest into theyre acreage.
