Diversity hotspots in manor gardens
PANGRÁC, Čeněk
This thesis study differences between insect diversity of manor gardens and economic forest, as well as the importance of manor gardens within the local biodiversity of insects. Data were collected at six localities (Vlašim, Konopiště, Vrchotovy Janovice, Hluboká nad Vltavou, Český Krumlov and Třeboň). Carabids were collected in spring, summer and autumn terms during 2019. The specimens were collected via pitfall traps. There was inspected no statistically significantdifference in the diversity valuesbetweengardensand forests. The individual data showed a close relation between insect and plant diversity, as well as indicative species for garden and forest areas. The importance of manor gardens was identified primarily in a landscape which is intensively used for agriculture or with a lower proportion of natural habitats.

Srovnání diverzity vybraných skupin epigeických členovců v hospodářském nížinném lese s různou věkovou strukturou a typem managementu
Staněk, Luboš
The aim of this thesis is to investigate the species richness and abundance of epigeic arthropods (spiders, ground beetles, centipedes, millipedes, woodlice) in relation to different age structure and types of forest management. The arthropods were sampled from four different age classes (clearings, young, middle-aged and old forest stands), while within two of them (clearings and old forest stands) the influence of management was also evaluated. According to comparison of stages of forest succession most species were found in clearings without any mechanical soil preparation. On the other hand younger age classes hosted the least amount of arthropod species. The highest abundances of species were detected within young forest stands whereas the lowest in middle-aged stands. The results of forest management impacts indicate that soil milling is not suitable for any investigated group of organisms. The response to management of the old stands varied for different arthropod groups. The results reveal high importance of diversified silviculture in form of various age classes, a regulation is also necessary to restrict large area milling of clearings and for both managed and unmanaged forest stands the continuity must be maintained.

Průběh sukcese lesa na kalamitní holině Soběšice
Žouželková, Lenka
This bachelor thesis has been processed on the territory of SLP ML Křtiny - Soběšice. The aim of the study was to evaluate the development of the succession focusing especialy on woody component (years 2012-2014) on salvage glade after the disintegration of young pine small pole stage by wet snow. Data collection and analysis was conducted on the network of 87 inventory plots in 3 variants of soil preparation: without intervention (41), chemical (23) and mechanical (23). On the plots were registered seven kinds of trees, the numbers per hectare decreased gradually from 7500 to 5000 units / ha. On the whole area was dominated by hornbeam and oak. The largest occurrence and density of trees was registered in mechanical preparation. In the first two years was dominated second high-rise category. (20-50 cm) and in 2014 it was the third category from 50 to 130 cm. Altogether were found 34 kinds of herbs and shrubs. The average coverage increased from 43% in 2012 to 81% in 2014. The greatest coverage was in 2014 detected in mechanical preparation and chemical variant was the lowest. Dominating substrate of soil all the time was the mineral soil. Under current legislation the state determined of ascertained state regeneration after 5 years since the establishment of clearing does not meet the time nor the space beyond regeneration, or minimum numbers per hectare. The results showed the best use of self-development with assuming completion artificial regeneration, and interventions against weeds. It must be long-term monitoring.

The design of educational program about the problematic of Šumava spruce forests
BLAŽKOVÁ, Miluše
The bachelor thesis is focused on the design of educational program about the problematic of Šumava spruce forests. To increase the applicability of the program, it is feasible not only in the Šumava spruce forest, but also in a common spruce plantation. The program is designed especially for pupils of elementary schools. The work contains a detailed description of tasks and activities, preparation of worksheets with notes and suggestions for lectors. Activities are designed mostly so that children are in a direct contact with nature. There are elements of inquiry based education, also the didactic play and group education is used. A part of the educational program was verified in practice and then some corrections were applied.

Comparison of biodiversity in managed forests with the different species composition and age structure - communities of epigeic beetles
MATĚJŮ, Aleš
Communities of epigeic beetles were studied on five forest habitats with the different age structure in the Novohradské foothills area (Český Krumlov district, South Bohemia, Czech Republic). All studied habitats were found in three managed forests. The method of pitfall trapping was used for beetle sampling. There were 2735 specimens trapped. 25 beetles species were divided into two groups by its ecological preferences to the degree of human impact. Index of antropogenic influence had better values in two oldest studied habitats. Species diversity was higher in the oldest habitats too. The results indicate less human impact in mature managed forests than clearings and young managed forest stands.
