Vegetation of old fields and its dynamics in relation to changes of arable land in Czech Banat (Romania)
 Veselý, Adam ; Kovář, Pavel (advisor) ; Vojta, Jaroslav (referee)
- 4 - Abstract Recent abandonment of arable land close to the Czech villages originated in Romanian area called Banat during 19th century implies new variety of habitats representing old fields of different age. We can observe succesional stages of vegetation variable in plant diversity, in some cases significantly high with a number of plant species valuable from the viewpoint of nature protection. Some of these species were known as common in Czechlands as well, but nowadays are strongly endangered or completely extinct. Among others, the number of pieces of cattle in Banat has been reduced. This is the reason why traditional pastures have been grazed less intensively, especially those situated in hardly available localities (e.g. karst valleys and slopes) and often shared with neighborhood villages (including Romanian ones). The abandonment of arable fields thus facilitates the landuse by the way of more productive pastures with better availability from the villages. Next steps of secondary succession and the lost of traditional cycle of the land cultivation sparse shrubs are becoming an important part of the old field vegetation structure, which moreover have a strong influence on the potential restoration of forest ecosystems. The main aim of this thesis is to asses the process on the abandoning of...
