The agri-environmental-climate measures (AECM) announced by the Ministry of Agriculture of the Czech Republic are intended to support management methods mitigating the negative effects of intensive farming on the landscape and its inhabitants, including insects. Despite their productive nature, permanent grasslands are an important landscape component hosting a wide range of invertebrates. The right balance of production practices and compensatory measures can make a significant contribution to maintaining the diversity of grassland organisms and the ecosystem services they provide. The Nature Conservation Agency of the Czech Republic (NCA CR) has therefore commissioned a study on the effects of temporarily unmown grass strips on the diversity and abundance of meadow organisms. The aim of the study was to verify whether the retained parts of grass stands have a positive effect on the biota on common managed meadows of various sizes.

Yes, this is possible. Although computer modelling will not save the Black grouse, its outputs can significantly help in planning various practical measures in the field, regulating tourists at high-risk sites, and educating visitors. Habitat modelling, which uses the possibilities of geo-information technologies, remote sensing data, and advanced spatial analysis methods (e.g. Hirzel & le lay 2008, ElitH & leatHwick 2009), is applied significantly in the study of ecological requirements of (not only) animal species. These methods, technologies, and data allow extensive analyses of the relationships between the occurrence of species of interest and relevant environmental factors (e.g. Franklin 2010, Guisan et al. 2017). A common approach is to model the current or potential occurrence of species (e.g. tHuiller et al. 2004, Hirzel et al. 2006, Basille et al. 2008); the aim is to determine the landscape potential for their perma- nent or temporary occurrence and to evaluate the significance of individual environmental factors for their spatial expansion. Thus, habitat modelling is currently one of the most widely used approaches in conservation biology (e.g. Huck et al. 2010, Basille et al. 2013, Guisan et al. 2013).

Ten years ago, the Nature Conservation Agency of the Czech Republic (NCA CR) began to conclude agreements on management through public contracts, setting up both management measures to be implemented and providing landowners or tenants with a subsidy / subvention. Consequently this practice has been step-by-step applied also by other State Nature Conservancy authorities, particularly Regional Offices. At present the agreements on management are one of the principal and commonly used tools in cooperation with land managers. The NCA CR is currently taking active steps to further expand the type of cooperation with landowners, our most important partners in practical nature conservation.

Shepherd dogs guarding livestock are rightly recommended as the most effective measure against grey wolves (Canis lupus) attacking livestock. Farmers are often criticized for hesitating to acquire shepherd dogs. However, few people can imagine the long and challenging journey to a reliable working shepherd dog.

The Moravský kras/Moravian Karst (central Moravia) is the most important karst area in the Czech Republic. In addition to underground karst phenomena, we can also find surface aboveground karst phenomena there, which include sinkholes and limestone pavements. All these karst phenomena are legally protected. The uniqueness of the area is also confirmed by the only internationally protected underground wetland in the Czech Republic, which is the Podzemní Punkva/Punkva Subterranean Stream Wetland of International Importance (Ramsar Site). The karst environment needs our protection, not only below the surface but also at ground level, from where nitrates and pesticides from intensively managed karst plateaus enter the underground areas. These substances pollute groundwater, which is used as a source of drinking water and harbours a lot of animals. Changes in management around the sinkholes and above the caves implemented in 2019 and 2020, resulted not only in positive shifts in the agricultural landscape, but they also significantly contributed to improving the quality of drip water that seeps down to the caves through the soil and rocks.

Mineral and rock mining carried out for centuries has had significantly negative impacts on the landscape and the environment in the Czech Republic. By size, the most extensive destruction in the whole country has been caused by surface open-pit brown coal mining in the Krušné hory/Ore Mountains Foothills Basin, also known as the North Bohemian Basin. More than 400 km² have been affected by mining and by related infrastructure and industry there. Nowadays, when a termination of active brown coal mining termination in the Sokolov and Most Basins¹ has been in sight, the future use of the closed quarries is being discussed extensively. Experts have long been aware of the great scientific significance of abandoned non-reclaimed excavations and spoil heaps. Therefore the question of applying ecosystem restoration to the above post-industrial habitats has been even more urgent than ever before.

The Nature Conservation Agency of the Czech Republic (NCA CR) has been for ten years elaborating together with academic institutions standards in nature conservation and landscape protection. Almost thirty such standards have been published yet and approx. the same number has been under preparation. Up-to-date experience shows that the concept of standardization in various activities has proved itself successful and has fulfilled its purpose: standards are used by designers, customers, planners, project implementers, contractors, evaluators of application for a subsidy/subvention/grant and they are also applied in the State/Public Administration performance. Moreover, they are sometimes misapplied. Thus, the standards at present have been serving as a basis for establishing unified code lists of activities in nature conservation and landscape protection linked to costs of common measures and consequently for planning and documenting the interventions having been made in nature and the landscape.

When presenting examples of particularly species-rich ecosystems, we will most probably name tropical coral reefs, tropical gallery forests or selected types of tropical rainforests. To visit these ecosystems, one must travel a long journey far outside of homeland, and even beyond borders of our continent. Still, a comparably species-rich ecosystem can be found, even in our conditions – yet escaping broader awareness when speaking about biodiversity. This is perhaps caused by simple fact, that thousands of species inhabiting this ecosystem could only rarely be observed by the naked eye, as they are mostly of the microscopic size. Indeed, healthy, and well-functioning soil – in our conditions mostly soil of broad-leaved deciduous or mixed forests – is a real biodiversity hotspot reachable just “beyond our courtyards” or next door. Presence of the particular species, overall species richness and relative numbers of soil organisms serves at the same time as great indicator of soil conditions, and often also of the quality of respective above-ground ecosystem at the place.

What comes to mind when you hear the word the Bílé Karpaty/White Carpathians Mts.? A hundred years ago it was still the most remote corner of the Czech Republic, from which people were leaving for America to find a job. Today it is a popular destination for an increasing number of visitors of the entire country. Everyone will come up with something else – probably most often meadows full of orchids stretching to the horizon, but also (from west to east) wine cellars near the municipality of Petrov and the town of Strážnice, old service/sorb trees (Sorbus domestica), the Horňácko/Upper Moravian Slovakia region folk culture, the Moravian Kopanice region with the Goddesses of Žítková, the virgin forest below the top of Mt. Velká Javořina/Great Maple Forest, beech forests in the Vlára Pass, or the well-preserved landscape of Southern Moravian Wallachia around the municipality of Nedašov. The landscape and nature of the picturesque mountains on the Slovak border has really extremely many faces.

The lunar landscape image of coalmine regions keeps clinging to people’s minds, despite the fact that a lot of good has happened since the boom of brown coal surface mining below the Krušné hory/Ore Mountains (northwestern Bohemia). Mining companies are in good faith fulfilling their mining obligations including the reclamation of spoil heaps and residue pits in extensive surface quarries as is imposed by law, primarily the Mining Act, the Forest Act and the Act on the Protection of Agricultural Land. An area of more than 12,000 hectares has already been technologically and biologically reclaimed, and at least CZK 20 billion (EUR 0.8 billion) have been invested there (figure converted to today’s value of the Czech Crown based on common reclamation prices) from the miners’ financial reserves as well as governmental resources (see www.15miliard.cz).
