Biotopes associated with railway corridor in valley of the river Tichá Orlice (Eastern Bohemia, Czech Republic) ABSTRACT Expansion, invasion or decline of plant species caused by environmental changes belong to the most important phenomenons associated with vegetation cover development. In spite of their often initiation by human activities the above mentioned processes continue then spontaneously and uncontrollably. This study is concentrated to the effect of these mechanisms on the biotope structure along the Tichá Orlice River (Eastern Bohemia, Czech Republic) - in its lowland landscape segment of the canyon character where the second axis of the valley (river flow is the first one) is created by railway line more than 150 years of local history. The case study has the general aim: to treat the present and/or future impact of described trends to plant biota and the degree of its influencing. My diploma thesis investigates functional impact and mutual interaction of the two main migration pathways of exotic species - the T.Orlice river and the railway corridor. It presents qualitative and quantitative changes in plant components of local (semi)natural biotopes by mean of interrelationships among selected ecological groups of species (neophytes, expansive species, and ephemeroids). At the same time, this...

The impact ofthe construction ofthe golf courseon the environment- the project EIA Český Krumlov
HÁVOVÁ, Nikol
The theme of this diploma thesis was effect building a golf course on the environment - EIA Czech Krumlov. On location Kvítkův Dvůr in Czech Krumlov was suggested build an 18-hole golf course. Construction of a golf course in this area may significantly distort the historical landscape. On the given locality conducted a biological exploration. Research has proved that there are no rare or endangered plant and animal species, therefore, the realization was possible. However Kvítkův Dvůr is an important cultural monument, which falls into the protection zone urban conservation.

The peat quality and vegetation composition depending on land use
LEŠTINOVÁ, Iveta
Borkovická blata (moors) represent the largen bog in Třeboň Basin Area. Previously, there was mined pea tuntil 1979. The best preserved part of the moors was declared aprotected area in 1980. The mining impacted not only them so their immediate surroundings and landscape use. The work deals with the management of the surrounding areas, and how it may affect the quality of peatand its vegetation cover in nature reserve Borkovická blata. Fieldwork consisted of two parts: the first collection of peat and its chemical analysis (conducted in 20102011); second relevés with the development of land use surrounding areas (fieldwork was carried out from July to October 2014). On the moor were selected four phytocenological sites on the size of 5x5 m, on which were carried out sampling and survey. Selected sites showed at first glance significant differences by way of former use.
