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.

Global and regional biodiversity loss is caused by several drivers including urban development, land use intensification, overexploitation of natural resources, environmental pollution, and climate change. The main aim of our study was to adapt the GLOBIO3 model to the conditions of the Czech Republic (CR) to assess loss of naturalness and biodiversity vulnerability at the habitat level on a detailed scale across the entire CR. An additional aim was to assess the main drivers affecting the biodiversity of habitat types. The GLOBIO3 model was adapted to CZ-GLOBIO by adapting global to local scales and using habitat quality and naturalness data instead of species occurrence data. The total mean species abundance (MSA) index of habitat quality, calculated from the spatial overlay of the four MSA indicators by our new equation, reached the value 0.62. The total value of MSA for natural and near-natural habitats was found to be affected mainly by infrastructure development and fragmentation. Simultaneously, intensity of land use change and atmospheric nitrogen deposition contributed primarily to the low total value of MSA for distant natural habitats. The CZ-GLOBIO model can be an important tool in political decision making to reduce the impact of the main drivers on habitat biodiversity in the CR.

<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>

: At present, the coppice-with-standards system has become so rare in floodplain forests that it is considered a natural monument. In 1990, the coppice-with-standards system was not recorded in the territory of the Czech Republic. This state contradicts the increasing interest of nature protection organizations in the relict remainders of the coppice-with-standards system, which is to be considered the closest to naturally preserved lowland forest type, and is, therefore, recommended as the final state of the biocentres and biocorridors in today’s floodplain forests. The aim of this paper is to present the results of the inventory dealing with the present occurrence of the coppice-with-standards system in the floodplain forest of the Litovelské Pomoraví Protected Landscape Area (PLA) in a historical context.

AbstrakKekayaan Indonesia akan keanekaragaman hayati dengan komponen-komponennyamerupakan masa depan umat manusia sebagai sumber ketahanan pangan, kesehatan dan bahkan energi. Dengan potensi ini,Indonesia wajib melakukan upaya konservasi beserta legislasi yang efektif untuk mengatasi laju kerusakan dan kehilangan keaneragaman hayati yang telah mencapai tingkat yang sangat mengkhawatirkan.Tulisan ini membahas mengenai peran hukum dan kerangka hukum konservasi di Indonesia,utamanya kemampuan undang-undang konservasi dalam penyelamatan sumber daya alam hayati, serta saran perbaikan terhadap undang-undang yang saat ini ada.Saat ini kerangka hukum nasional konservasi keanekaragaman hayati berpusat pada Undang-UndangNo. 5Tahun 1990yang mengadopsi World Conservation Strategy IUCN tahun 1980 yang di tingkat internasional telah mengalami perubahan-perubahan mendasar. Terlepas dari keberhasilan UUini, diantaranya dengan mencadangkan lebih dari 25 juta ha ekosistem daratan dan lautan ke dalam sistem kawasan yang dilindungi (protected areas), undang-undang ini mengandung berbagai kelemahan untuk penerapannya saat ini dan perlu segera direvisi, termasuk harmonisasi yang mendalam dengan undang-undang terkait agar dapat dilaksanakan secara efektif di lapangan.  AbstractBiodiversity and its components: genetic resources, species and ecosystem with actual or potential use values to humanity is the future for the survival of humankind. With this potential, it is essential for Indonesia to conserve these resources equipped with effective national legislation to stop and reverse the unprecendented rate of biodiversity loss. This paper aims to discuss the conservation legal framework in Indonesia and the capability of the conservation law to halt unprecedented biodiversity loss and suggested revision for this law.The current legal framework for biodiversity conservation stems on the Act No 5 of 1990 which adopts World Conservation Strategy of IUCN 1980. Under the current framework,  more than 25 million hectares of terrestrial and marine areas have been totally protected within protected areas systems. However, this centralistic law has some weaknesses to be effectively implemented at the current contexts. This law needs substantial revision and harmonization with other laws in order to make the implementation effective.

Conservation of crops is based on <I>ex situ </I>collection into gene banks. Additionally, crop’s wild relatives can be conserved <I>in situ</I>, and landraces and obsolete cultivars also can be conserved using the on-farm method. The definition and methodology of on-farm conservation is discussed. On-farm conservation has been set up in the Czech Republic as model examples in several institutions dealing with nature protection, education, cultural conservation, as well as by some private farmers. Problems, plus positive and negative experiences are presented. On-farm conservation in open-air-museums in the natur (skansens) as well as in the national parks, seem to be suitable ways forward for the Czech Republic.
