Evaluation of landscape permeability and migration potential - A Case Study on the motorway D10
Novák, Libor ; Keken, Zdeněk (advisor) ; Kušta, Tomáš (referee)
This thesis deals with the influence of technical barriers to accidents with wild animals. On the highway D10 during the years 2006-2014 a total of 598 accidents with animals happened. Six categories of barriers were determine: 1) no barrier, 2) metal guardrails, 3) concrete dividers, 4) reinforced metal guardrails, 5) noise barrier wall, 6) fence, which had been given spatial location during the field survey. The paper also addressed the impact of urbanized areas and created the density of accidents per 1 km of the highway. The results show that there was no evidence for an effect of technical barriers (p = 0.73164). An analysis of accidents density implies some hotspots where there is > 19 accidents / km.

Environmental Impact Assessment Follow up analysis of Pankrác administrative centre
Franclová, Alena ; Keken, Zdeněk (advisor) ; Karel, Karel (referee)
This diploma thesis evaluates issues of environmental impact assessment, focusing on post-project analysis of the Pankrác administrative center. Follow-up evaluation is one of the most important practice through EIA which can fulfil one's potential. Major contribution is mainly the EIA feedback which will be compared between real and predicted impact. Follow-up will provide knowledge to avoid possible non-conformances in EIA evaluation process in the future. Methodical of this thesis is based on international standards of good practice in EIA follow-up, which should always correspond with the specific circumstances of the project and the specific context. The main principles are results-oriented approach, learning, institutional commitment and responsibility. Meaning of the follow-up is the main research question to evaluate the environmental impact assessment. The thesis evaluates the implementation of the main comments from the various point of views. All opinions, changes and views of all participants must be reviewed in implementation and operation phases of the EIA process. Another sub-section provides a comparison of the noise pollution before and after realization of the project and analytical part concludes evaluate compliance with the general principles of good practice. The results collect comprehensive assessment of the EIA process. The follow-up for Pankrác administrative center was important and it proved that positive cooperation with the investor made processes more effective in the terms of the environmental protection of the area. In the future it would be appropriate to dedicate more effort and time for the follow-up. Especially raising awareness of the existence and positive impact of the entire EIA process and also to protect the environmental and public health.

Temporal and spatial changes of woody vegetation at the landscape - case study (former Vrchlabi estate)
Juřičková, Beata ; Skaloš, Jan (advisor) ; Keken, Zdeněk (referee)
This dissertation deals with a temporal and spatial changes of woody vegetation at the landscape in West Bohemia. The case study helps to recognise a historical development of the landscape and focuses on landscape elements of forest and non-forest woody vegetation.
Focused area was determined by borders of former Vrchlabi manor and based on historical documents. The chosen area partly belongs to zone 1, 2 and 3 of Krkonose National Park.
Forest and non-forest woody vegetation was compared from different sources- a map of Imperial imprints of the stable Cadastre from 1843, an aerial images from 1950 and an orthophoto images from 2014 - using ArcGIS software. Woody vegetation was divided into forest category and other three non-forest woody category- draws, acompanying woody vegetation and line.
The results have shown that the most consistent category has always been the forest, spreading on 42,25% of the area in last 171 years. The non-forest woody vegetation was developing erratically and was covering the largest area of 335,21 ha in 1950. Data analysis have shown that each period of forest and non-forest woody vegetation has its own specific trends.

Environmental risks Assessment arising from the implementation and operation of biogas-stations
Onderková, Petra ; Keken, Zdeněk (advisor) ; Pavel, Pavel (referee)
Environmental pollution, natural resources consumption and global climate change have been threats for mankind since 21 century. In order to antedate environmental pollution in many countries of the world including The Czech Republic we use legislative tool as a process of influence of the environment EIA. Substitution of non-renewable energy sources for renewable ones may retard global climate change markedly.
This thesis deals with analysis of specific biogas plants located in Moravian-Silesian region in relation to the environment and population.
It means that it deals with biomass utilization as a renewable source of energy. Within EIA process, it assesses the unity rate between prediction, said
in documentation, and the real state after implementation. As far as the population perspective is concerned, poeple assess great strength, weaknesses, opportunities
and threats.
Results of the research showed different perceptions of biogas before and after project implementation. The risk of discomfort housing (smell, increased traffic congestion, noise) threatens residents in older facilities where an EIA was not yet part of the legislation. The results also showed compliance with the information provided in the EIA documentation in relation to the population and the environment, and the state after realizing the plan of a biogas plant.
The thesis brings us new information within post-project analysis, it shows us the importance of EIA process and publicity involvement into this process. Defining the specific effects of biogas plants by mutual cooperation between the investor
and the public authorities can be achieved some functioning device with regard
to population and environmental components.
