Flora and vegetation in the the Jedlový potok floodplain (Šumava National Park)
HORKÁ, Eliška
The Jedlový potok is a left-bank tributary of The Teplá Vltava river, in the district of Prachatice, which is a part of The Hornovltavský luh in The Šumava National Park. In 2015, the project was approved and revitalization of the creek's part was done. The objective of the Bachelor Thesis was to document the flora and vegetation on predetermined areas of permanent crops located in proximity to The Jedlový potok five years after doing a hydrological revitalization. Four types of biotopes were identified here. Two of the biotopes are of a peat nature and balanced water level, located further away from the creek. Two more biotopes have a fluctuating water regime and are located in close proximity to the creek. It is a wet meadow full of cirsium and carex plants. Measurement of the water level was done in case of every habitat. 63 plant species were traced here. The data of this Bachelor Thesis, together with other data gathered after the revitalization, are useful for monitoring whether the development of the plant community is heading in the right direction.

Botanical survey of the Jedlový potok stream (Šumava National Park) three years after a hydrological restoration
ČERMÁKOVÁ, Monika
The Jedlový potok is situated in the Šumava National Park and it is a part of the Hornovltavský luh wetland komplex. In the 1950s, due to peat extraction, the stream was regulated and it drained the surrounding area including its floodplain. After a project creation and approval, part of the stream bed was restored, in 2015. Since then four ambient habitats have been monitored annually. Two permanent plots were set on each of them. The aim of the thesis was to record flora and vegetation on these plots in the fourth year after its restoration. Two types of habitats are located in a close vicinity of the stream bed. These are species-rich wet Cirsium meadow and dense vegetation of Phalaris arundinacea marsh with a dominant species Phalaris arundinacea. The other two habitats have a peaty character and they are located out of the riparian zone, further away from the stream. These are short-sedge fen and species-poor Eriophorum vaginatum mire. The used methods included fytocenologic relevés and also groundwater level measurement. In the whole area a total of 83 plant species were identified. The data of this thesis, also with other acquired data from the Jedlový potok area, are useful for further tracking of the vegetation development and also aids to find out if the restoration helped to recover the hydrologic connection between the stream and its surroundings.

Monitoring výskytu invazních neofytů v povodí Zdobnice (CHKO Orlické hory)
Vágner, Jan
Mapping of selected invasive neophytes along the rivercourse of Zdobnice river, particularly in the part of the river flowing through the protected landscape area of the Orlické mountains, was done within this bachelor thesis. The monitoring took place in July of 2016. A 1:10 000 map was used for recording of the occurrence of above mentioned neophytes into their respective extension categories. 20 fytocenologic images from respective biotops were created during fieldwork. Forest type Groups were then assigned to their respective images. Turboveg 2.0, Microsoft Excel 2016, and ArcGIS 10.3.1 were used for the elaboration of the results, where a map in digital form was created. The most abundant type was Glandular nettle, which occurres mostly in ruderal biotops. Other types, such as Reynoutria japonica or Telekia speciosa participate in the invasions greatly as well. The rest of the taxons from Reynoutria genus were not observed in the incriminated area. The biotop of gravel river bedding was evaluated as the most threatened by the cooperation of Reynoutria, Telekia a Impatiens. When compared to similarly focused works, we can say that Impatiens confirmed its dominant role even in this work, as well.

Botanical survey of a restored segment of the Jedlový stream (Šumava National Park)
PADRTOVÁ, Markéta
The Jedlový Potok is a tributary of the Teplá Vltava River and is situated in the Upper Vltava Floodplain in the Šumava National Park. Part of the Jedlový Potok has been restored in 2015. The aim of the thesis was to record the flora on permanent plots in the Jedlový potok floodplain in the third year after its restoration. Four type of habitats were distinguished in the Jedlový potok floodplain. An extensively mown wet Cirsium meadow and Phalaris arundinacea marsh occurred in the riparian zone with a more fluctuating water table while a short-sedge fen and an Eriophorum vaginatum mire formed a peatland zone further away from the watercourse. Phytosociological relevés were recorded and groundwater table level was measured on two permanent plots within each habitat. Eighty plant species were recorded on the permanent plots. A total of 124 vascular plants was identified in the whole area of interest in the Jedlový Potok floodplain, 17 endangered species included. The botanical survey confirmed the spatial pattern of biotopes typical in the Teplá Vltava River floodplain and a high richness of the floodplain flora.

Landscape assessment of a selected river landscape
Kotápišová, Kateřina ; Halamová, Jana (advisor) ; Lucie, Lucie (referee)
Diploma thesis deals with landscape evaluation of river Vltava on its lower stream in area between Roztoky and Mělník.
The theoretical part is focused on definitions of terms associated with watercourse and landscape of river floodplain. This part is describing function of river floodplain, human effect on landscape, shows the issues which are presented in landscape and describe ways of using landscape. Further it is deals with understanding of landscape, pattern of river landscape in art,characterizes the ideal state and negatively affected state of flux and provides approaches to the formation of river alluvium.
In the practical part are defined the boundaries of area and done a detail analysis of natural conditions, the historical development and exploitation of river flow at first.
The part of project was a creation of method useful for evaluations landscape. Based on in situ examination, area was divided into separate categories according visual quality of environment (landscape). The framework recommendations were created for each area categories and it should lead to conservation and protection the values of the landscape or improve its state. The detailed analysis of landscape evolution in terms of size and shape of areas and land cover was performed with use of historical maps. Thereafter the most affected area by human activity with the worst evaluation was chosen. For this chosen area were developed other analyzes as a base for suggestion of the solution.
Due to intensive use of river landscape the concept solution is focused on improve permeability, the habitability and landscape restoration of landscape structures.

Botanical survey of a restored segment of the Jedlový stream (Šumava National Park)
PETRŮ, Jan
The thesis is part of project "Bohemian Revitalization of wetlands and peatlands". The aim is to catch up the current state (before revitalization) of vegetation and flora with possibility of the existence of rare endagered species in Fir Stream plains in the Southern Bohemia, district Prachatice, cadastral area Volary. There was engaged generic list of plants in this interest locality. There was defined by the 6 permanent areas with dimensions 4x4 m. I made a complete inventory of all found species. Overall, it was found 38 plant species: 11 monocotyledonous plants, 25 dicotyledonous plants and 2 bryophytes.
