Visitors Monitoring Importance for Protected Areas on the NPR Vůznice Case Study
Skalková, Petra ; Patzelt, Zdeněk (advisor) ; Třebický, Viktor (referee)
Protected areas, which now cover 11 % of the earth's surface (Rodrigues et al., 2004), play a vital role in tourism and they are being visited by more and more people (Buckley, 2003). These areas have been declared to protect species and habitats from being disturbed by visitors and from habit degradation (Kelly et al., 2002; Boo, 1990). This thesis deals with the monitoring and evaluation of tourism impact of illegal traffic to the National Nature Reserve Vůznice. In this study I have focused on three main units: firstly the vegetation - we mapped the specially protected plant species and habitats assessed valuables in ArcGIS, secondly the evaluation of the impact on bird and finally the monitoring of tourism. Valuable habitat is mixed and very valuable habitats are mainly located in the valley of NPR Vůznice, including roadsides. In contrast, less valuable habitats are spread irregularly. I found 11 kinds of plants protected by law while monitoring endangered plants in the area. Among specially protected species in the area surrounding roads are spring snowflake Leucojum vernum (Spring Snowflake), Lunaria Rediviva (Perennial Honesty), Lilium martagon (Martagon Lily) and a greater proportion of important species is located off roads on slopes, e.g. Aurinia saxatilis (Basket of Gold), Dictamnus...

The proposed project focusing on the use of fluorescent properties during tracer tests reflects the absecne of tracer substances not modifying the hydrochemical properties of the environment and not being radioactive. A positive result of the proposed research will enable more accurate evalutation of absorption properties of the rock environment in case of leakage of hazardous substances than it is for chemical tracers. Fluorescence salts offer the possibility of continuous monitoring of fluorescence changes without endangering the environment and without negative effects on hydrochemistry. Research will proceed according the fillowith scheme: bibliography-laboratory research-field tests-mathematical modeling. The project proposer has already acquired a patent and design rights in the frame of previous research project concerning the developed facility and technology enabling continuous monitoring and evaluation of fluorescence changes in liquids. The investigation of interaction between fluorescent salts and migratory pproperties of the rock environment will focus on rock with fracture permeability. Further selection of fluorescence salts accomplishing the objectives of the project will be based on the detailed bibliographic study. Particular fluorescent salts will be investigated in laboratory scale on selected rocs. Most promising fluorescence solutions will be consequently used for migration tests in specified rock environment with fracture permeability. The research polygon will be equipped with small-diameter boreholes interconnected by fracture network with two network section - with and without sorption properties. The results of both, laboratory and field tests, will be validated by mathematical models.
