TITLE: Evaluation of ecosystem integrity and services on regional level with the use of participatory approaches AUTHOR: Mgr. Jakub Zelený DEPARTMENT: Environmental studies SUPERVISOR: Mgr. Davina Elena Vačkářová, Ph.D. ABSTRACT: The presented work proposes and applies a set of methods designed to describe ecosystem integrity, services and landscape values, including their interaction, on the example of several studied regions. The included publications describes 4 types of methods for evaluating these phenomena: remote sensing of the Earth, regional statistics, expert matrices, and qualitative interviews and mapping. Applied methods can be divided into natural sciences and social sciences, and part of the work is to evaluate the benefits and compare the compatibility between these very different methods in evaluating selected elements of landscapes. The methods are applied in a variety of ranges, ranging from urban areas (10 km2) to the federal states. Natural ecosystems and forests have been assessed best in terms of ecosystem integrity, with the relationship between ecosystem integrity and crop production being negative. Qualitative mapping of landscape values revealed that pristine and inaccessible areas, as well as single- purpose sites, had low societal value in terms of intensity and / or diversity...
Assessing ecosystem services and the alternatives of their future development in UNESCO Biosphere Reserves
Harmáčková, Veronika Zuzana ; Vačkářová, Davina Elena (advisor) ; Cudlínová, Eva (referee) ; Pechanec, Vilém (referee)
The provision of ecosystem services within social-ecological systems is influenced by multiple environmental and anthropogenic driving forces, affecting natural ecosystems. At the same time, the capacity of ecosystems to concurrently provide different types of ecosystem services is inherently limited. Thus, ecosystem changes and their effect on ecosystem services have direct implications for human existence and well-being. The aim of this thesis is to present a modelling approach to assess regulating, provisioning and cultural ecosystem services and to quantify their potential trade-offs, illustrated by two case studies carried out in selected UNESCO Biosphere Reserves in the Czech Republic, Třeboň Basin Biosphere Reserve and Šumava Biosphere Reserve. Both of the selected case study areas are characterized by high levels of natural and cultural assets and challenges regarding future landscape management. In this study, first the social-ecological dynamics within the study areas was analysed by creating participative scenarios through collaboration with local stakeholders, eliciting their preferences regarding future landscape development to 2050. Second, the impact of the scenarios on ecosystem services and their trade-offs were assessed using a combination of spatially explicit models and...

Most ecosystem services assessment tools attempt to quantify services on a landscape scale using simplified biophysical models or ecological functions. The most commonly used ecosystem classifications are land use / land cover or habitat, which can be combined with other information such as soil type or vegetation biomass. The aim of the study was to quantify selected ecosystem functions in the cities of Liberec and Děčín. For the evaluation of habitat biodiversity in 2003, a complete list of habitat types was prepared for the Czech Republic, which includes habitats processed in preparation of data for the creation of a national design of Natura 2000 sites of European importance (Habitat Catalog of the Czech Republic 2001 and 2010) and detailed description of more antropgenic influenced habitat (Sejak et al., 2003, Sejak et al., 2017). For 21 functional groups of habitat types, their production function, including oxygen production and the ability to minimize temperature fluctuations (to reduce the amount of radiated heat) was estimated to provide support and regulatory services to ecosystems (Seják et al. 2010). According to the assignment of the study, Elaboration of the layer of provision of selected ecosystem functions and services in the area of ​​interest of the cities of Liberec and Děčín, biodiversity values ​​determined according to BVM method, annual biomass, oxygen and evapotranspiration production for the entire cadastral territory of Liberec Kunratická and dam Harcov and for the cadastral area of ​​Děčín.
Geodiversity, secondary geodiversity and cultural heritage
Kirchner, Karel ; Kubalíková, Lucie ; Kuda, František ; Havlíček, M. ; Machar, I. ; Pechanec, V.
Within the framework of the NAKI II project – Cultural heritage of landscape of the Archdiocese of Olomouc - research, presentation and management (DGB 16P02B014), we focus on the results that will contribute to the sustainable development of regional cultural identity through applied cultural heritage research in the cultural landscape of the area of interest. As part of the material cultural heritage, we include the landforms that originated from the conscious activity of man - the anthropogenic relief forms. These landforms complement the geodiversity of the landscape and are referred to as secondary geodiversity, their identification and interpretation will make it possible to complement and enhance the diversity of cultural heritage and to specify the development of the cultural landscape. The first results from the Archdiocese of Olomouc are presented.

Therefore, their identification and interpretation will make it possible to complement and enhance the diversity of cultural heritage and to specify the development of the cultural landscape. The first results from the area of Central Moravia will be presented with the using of the historical maps, the digital model of the relief DMR5G and the field research.

Current possibilities for quantification and modeling of recreation services
Pechanec, V. ; Cudlín, Pavel ; Machar, I. ; Kilianová, H.
Ecosystems provide settings for a hugely diverse array of recreational activities. Recreational values are among the most well-recognized of all ecosystem services by the public, and human preferences for recreation have been well-studied by economists and other social scientists. From a spatial perspective, we can map sources of recreational value, sinks of recreational value, users of a particular recreation area for a given activity, and the spatial flow that connects users to specific recreational areas. The text presents two key approaches of modelling tools InVEST and ARIES. Methodological approaches are compared with each other and the requirements for data confronted with national data sources.
Prediction of changes in landscape and biodiversity development as important factors in maintaining the current state of forest ecosystems
Cudlín, Ondřej ; Pechanec, V. ; Purkyt, Jan ; Štěrbová, Lenka ; Holá, Š. ; Cienciala, E. ; Cudlín, Pavel
We used a combination of several analytical tools to analyse change and predict the land use, carbon storage and biodiversity assessment in the cultural landscape. First, the GIS layer, consisted of Habitat mapping (NCA CR 2014) for 138 natural and close to nature habitats and Corine LC for 54 more anthropically influenced habitats, was created. The Land Change Modeler (scenario type - business as usual, pixel resolution 500 m) was used to predict the development of land cover on the basis of data comparison in several historical periods (Corine LC from 1990, 2000, 2006, 2012). We also did prediction of carbon storage under climate change in model InVEST 3.0 – carbon. Changes in carbon storage were calculated from four carbon pools: above-ground biomass, below-ground biomass, necromass and soil organic carbon. To assess and predict the changes in biodiversity in the \nforest-agriculture landscape we used the model GLOBIO 3, which works with five basic driving forces for biodiversity loss: land use, infrastructure, fragmentation of territory, atmospheric nitrogen deposition and climate change. Last used model Marxan enables us to select up to now unprotected areas with a high degree of biodiversity and naturalness of habitats for environmentally friendly agriculture and forestry management.\n
