Milk thistle is grown in the Czech Republic as a medicinal herb; silymarin is isolated from its achenes and used for the production of liver and gallbladder medicine. The quality and content of the active compound is influenced not only by environmental factors, but also by pests and pathogens. The occurrence of pests of milk thistle variety Silyb was observed in two localities during the years 2011 2013. In the year 2011 the mycoflora of seeds of four milk thistle varieties was determined. Representatives of 15 species were isolated from the seeds, most of them saprophytic. 21 fungal species were isolated and identified from milk thistle plants during the vegetation; Septoria silybi among the most important ones. Possibilities of protection of milt thistle against pathogens are discussed.

<p>Establishing legal protection to a geosite (or geodiversity site) is considered one of the key tools of how to conserve its values and how to avoid degradation and devastation. The proper management measures (usually included in care plans or other planning and strategic documentation) then help to balance the conservation needs and sustainable use of the sites and allow to gain public finances for these purposes.</p><p>In the Czech Republic, nature conservation is anchored in Act n. 114/1992 Coll. (Nature Conservation Act) which defines several levels of protected areas that can be applied also on geoheritage. However, there are other legislative tools that protect other entities (e.g. agricultural land, water, or forests). The special relationship to geodiversity has Act n. 44/1988 Coll. (Mining Act) which aims to protect the mineral deposits including their deposit areas. Various tools for the protection applied to a single area can cause ambiguities because every protected entity has different management and limitations.</p><p>This is the case of Hády Hill, an area situated in the outskirts of Brno, the second-largest city in the Czech Republic. The area is important from the Earth Science point of view (tectonics, paleontology, geomorphology, stratigraphy, hydrogeology) and has high ecological and cultural values, e.g. occurrence of endangered species linked to the subsoil, remnants of old landscape structures (orchards, pastures), historical mining, use of the building material for Brno monuments. Earth-science and ecological values are protected according to Nature Conservation Act within one National Nature Reserve, two Nature Monuments, and four Important Landscape Elements and partly included in Special Area of Conservation (according to the Habitats Directive - Council Directive 92/43/EEC). Moreover, due to the occurrence of quality limestone, which was extracted from the Middle Ages up to the end of the 20<sup>th</sup> Century, the part of the study area is declared as a reserved mineral deposit and protected deposit area (according to Mining Act). All these areas mutually overlap.</p><p>Concerning geoheritage, some phenomena still have no degree of protection, but they are included in the Database of Geological Localities (kept by the Czech Geological Survey) and proposed for legal protection.</p><p>Last but not least, the site undergoes tourist and recreational pressure which is continuously increasing due to the COVID-19 situation (lack of indoor possibilities of how to spend the free time).</p><p>To find the balance between the various conservation needs, management measures, limitations, tourist/recreation pressure, and urban development, it was necessary to do a complex analysis of the various types of protected areas and their values. Based on the SWOT analysis and Risk Assessment, the main threats, risks, and possible conflicts of interest were identified and assessed. Then, specific proposals and possible solutions were designed with an emphasis on effective geoconservation (e.g. declaration of the new or enlarging the currently protected areas), development of sustainable forms of tourism, and future rational use of an area (e.g. via volunteer activities or participative planning of management).</p>

AbstractThis paper aims to analyze the regional cooperation which ensures stability and good relations to neighbours and other V4 countries and helps to enforce collaborations across Europe in many fields such as education, tourism and economic development. Another field of activity of the Visegrad Group is a joint positioning in international tourism which will be addressed in this article on the background of the current coronavirus crisis. The empirical part consists of a SWOT analysis for Visegrad group challenges and a PASTA Analysis with which the effects of the coronavirus pandemic on the tourism industry in the V4 countries are researched. Lastly, recommendations for possible further actions in times of the coronavirus will be given, and potential future collaborations with the WB6 and EaP countries, also with regard to tourism, will be dealt with briefly. This article summarizes aspects related to tourism market, transport, cultural offer, economy, industry, and environment. The particular focus is also paid to political, economic, sociological, technological, legal and environmental factors of the Czech Republic, Poland, Hungary and Slovakia and how the current coronavirus and the resulting measures against the spread of it affects the tourism industry in the Visegrad Group countries.

The joint impact of human activities and climate change on natural resources lead to biodiversity loss. Therefore, it is important to select protected areas through systematic conservation planning. The present study assessed how representative natural habitats are protected under the nature conservation network, and to identify new—but so far insufficiently—protected areas containing these habitats for sustainable management. We used the Marxan model to select the most valuable insufficiently protected natural habitats in the Czech Republic as a representative example for a conservation strategy for Central–Eastern European environments. We set three conservation targets (25%, 50%, and 75%), defining how much percent area of valuable representative natural habitats should be added to the area of the habitats already included in the Nature Protection Network. To implement these conservation targets it is necessary to preserve 22,932 ha, 72,429, ha and 124,363 ha respectively of the conservation targets occurring in the insufficiently protected areas, and 17,255 ha, 51,620 ha, and 84,993 ha respectively of the conservation features in the areas without protection status. Marxan was revealed to be an appropriate tool to select the most valuable and insufficiently protected natural habitats for sustainable management.
