Verification of fenological model of Ips typographus in the Czech Republic
Haramul, Michael ; Boublík, Karel (advisor) ; Holuša, Jaroslav (referee)
During the months of April and June 2014 the spruce bark beetle (Ips typographus L.) capturing was conducted into the pheromone traps followed by the verification of phenological model PHENIPS altogether at two study locations in the Czech Republic: Horní Planá in the southern Bohemia and Lipník nad Bečvou in the Olomouc region. The trapping was performed weekly with the help of pheromone tabular traps Theysohn which were equipped by pheromone-type evaporators Pheroprax from Chemipan. The aim of the study was to verify the validity of phenological model PHENIPS for the spruce bark beetle in the Czech Republic and verify whether the model is applicable for the Czech Republic. At the end of the 2014 season with the help of phenological models PHENIPS and the number of trapped bark beetle specimen the term of swarming and the term of colonization of host trees were determined. The sister generation activity was probably recorded in the several traps.

Close-to-nature forestry from the point of view of the Czech Bioplatform
Petřík, Petr ; Košulič ml., M. ; Košulič st., M. ; Hédl, Radim ; Svoboda, M. ; Hruška, J. ; Zatloukal, V. ; Boublík, Karel ; Poštulka, Z.
During the discussion on the National Forestry Program, the Forest panel of the Czech Bioplatform has claimed in the Czech forests in particular: elimination of clear-cutting, preference of the natural forest regeneration, employment of pioneer trees within recovering forests, reduction of high game-stocks, leaving of the forest model based on the age categorisation, ensuring biodiversity protection and its monitoring, retaining old trees and dead wood, increase of water retention potential and prevent forest wetlands desiccation, reducing or exclusion of tree aliens, providing environment-friendly afforestation on the non-forest land, reducing or exclusion of liming and fertilization and active participation of the Czech forestry in the issue of the global changes. Most of the requirements were integrated into the version of the Czech National Forestry Program that is now negotiated over the sectoral policy and prepared for the SEA process.

Potential natural vegetation of the model transect in Třeboň basin (South Bohemia, Czech Republic)
Boublík, Karel
The paper deals with preliminary results of reconstruction vegetation mapping based on geobiocoenological principles (soil, climatic and growth conditions) and published palynological studies from the study area. On the basis of occurrences and growth features of climax trees (especially Fagus sylvatica and Abies alba) and published palynological studies, I suppose lower potential occurrence of Pinus sylvestris and Quercus robur in contrary to existing reconstruction maps (maps of reconstructed natural vegetation, potential natural vegetation and forest site maps). In these maps, proportion of Fagus sylvatica is probably underestimated. I assume potential occurrence of beech forests or forests with a great proportion of beech also on dystric cambisols and podzols developed from gravel sand of pleistocene alluvial terraces or on pseudogleys.

Vegetation and geobiocoenological classification of silver fir forests of the Czech Republic – preliminary results
Boublík, Karel
Preliminary results of vegetation classification of silver fir (Abies alba) forests are given. Seven communities from three alliances were distinguished in the Czech Republic. Climax stage of vegetation on the habitats of each association was investigated by geobiocoenological methods. It is claimed, that fir forests are seminatural that originated by stronger human impact (incl. fir forests on pseudogleys). They depend on forest grazing, litter raking, and other forest management. Fagus sylvatica is supposed to be dominant or frequent tree under natural conditions.
