Ecological farming is relevant to protected areas. The aim of the study is to perform an analysis of farms applying organic farming measures as well as the analysis of the change of their areas in Aukštadvaris and Krekenava regional parks (RP). The object of the investigation - the farms of Aukštadvaris and Krekenava regional parks. The study is carried out to determine how many farms, forming the regional parks‘ territory, are managed according to the principles of organic farming. The change of the above- mentioned farming area for 2009-2011 is analyzed as well. Paluknys and Naujamiestis subdistricts, not incorporated into the territory of regional parks, were chosen for the comparison analysis. The analysis of the 2009 – 2011 period showed that the declared areas in Krekenava RP have decreased, and the area of farms applying organic measures has increased by 81.69 hectares (nearly 2.5 times). The number of organic farms increased by 1.5 times in Aukštadvaris RP over the period of 2009-2011, and the area has increased by 187.36 ha. The percentage calculations revealed that in 2011 the area of farms applying organic farming measures in Aukštadvaris RP made up 18.89 per cent of the total area declared, the number of farms - 6.61 per cent. The area of farms applying organic farming measures in Krekenava RP was only 1.71 per cent, measures were applied only by 1.89 per cent of all the declared.

The study focuses on protected landscape aesthetic quality assessment where the main problem is how to associate aesthetical and ecological approaches. High ecological quality does not often correlate with high landscape aesthetic quality, and this relationship may differ depending on specific ecosystem. The landscape aesthetic quality assessment historically developed on two approaches. One of them - expert approach, which has dominated in landscape planning and management practice, and the second - perception approach, which has dominated in research. In protected landscape aesthetic quality assessment traditional approaches will be revised by ecology and green philosophy aspects. The study example regards important natural and protected areas around river Lielupe - from Jelgava city to Kalnciems. This is the landscape with high heritage, natural, biological values and it is also living, recreation place for people. Therefore, cooperation between aesthetic and ecological approaches in landscape assessment is needed. The outdoor investigations were carried out in autumn 2006. There were photographs and video materials on the first stage of investigation. In the second part aesthetic quality of views was analyzed with expert approach. There were three main groups of evaluation criteria of protected landscape aesthetic quality. These covered design and compositional outlines - features, their quality and relationship among these features. The results showed that not all criteria are suitable and effective for evaluation of protected landscape aesthetic quality because of restriction of specific ecological conditions.

The information about gardens of the Duchy of Courland in the 17th century is scarce and fragmentary, as part of documents is lost or exported abroad during the war. The time of the Duchy and its baroque gardens is attributed to reign of E. J. Biron in the first half of the 18th century, when impressive palace ensembles were created the help of architects F. B. Rastrelli and S. Jensen, building of summer residences in Rundāle, Vircava, Svēte, Luste. They served as summer amusement gardens or parks. In their arrangement, a compositional connection with the palace, the front courtyard, outbuildings and the garden was sought. These summer residences were located in rural plain areas, thus, the features of natural area - water, floodplains, terrain, nature of plantations and materials were used. The choice of planting materials was influenced by the climatic conditions - harsh winters, short summers, late spring frosts or early autumn frosts. Therefore, in the Duke’s time gardens, there are no delicate plants such as jews, boxwood plants, peach and mandarin fruit trees imported from the Western Europe. The local trees and shrubs, fruit trees, spice plants were used, vegetable beds made. The study examines two of the Duchy’s summer residences at Vircava (Wūrzau) and Svēte (Swethof), the study of which, as already mentioned, is made difficult due to the relatively scarce information.

The study deals with issues related to the impact of Natura 2000 sites on local development of rural communes in Poland. The purpose of the study is an attempt at comparing the level of social-economic development of rural communes in which Natura 2000 sites are located within their borders against other communes where there are no such sites, based on an analysis of selected indices. The selected indices of social-economic development were analysed in 424 rural communes in six Polish provinces. The study uses statistical data from the Central Statistical Office from the years 2000-2013. The analysis indicates that rural areas with Natura 2000 network sites do not differ from other units of local government as far as the level of social-economic development is concerned and in some cases show even better results. In the ‘Natura’ communes – compared to units where there are no such sites – the level of total income is higher, along with the commune’s own income, and there is a higher level of investment expenditure. The conducted analysis allows for the statement that the presence of Natura 2000 sites does not hinder economic development of communes and only modifies the manner of preparation and implementation of an investment. It does not constitute a barrier to human activity on the condition that any such activity complies with the principles of sustainable development. This testifies to the higher economic activity of inhabitants in comparison to other units.

Development of tourism, understood as the result of human activity aimed at adapting space to the needs of tourism, requires a variety of specific spatial determinants recognized from the viewpoint of multi-dimensionality of tourist space. One of the major determinants of tourism intensity in an area are landscape values, including natural values. Natural elements of the environment (including the terrain, water reservoirs, and natural forms of land cover), sustainable landscape, or the unique cultural objects are the basis for long-term development of tourist activities. These values are characteristic of the so-called naturally valuable areas, including areas under the national and international law of different forms of nature protection. The paper aims at examining the relationship between the existing natural determinants affecting the development of tourism and the intensity of tourist movement as well as tourism intensity and the level of development of tourist facilities in the gminas of the Warmińsko-Mazurskie voivodship. The overall objective will be implemented in three stages. The first one will be to identify the existing natural determinants for the development of tourism in the Warmińsko-Mazurskie voivodship. The second phase will consist of an examination of the intensity of tourist movement and the level of the development of tourism by designating Schneider’s, Baretje’s and Defert’s indicators and the share of recreational areas. The final step will be to identify relationships between the variables obtained in the process of obtained in the two previous stages.

Semi-natural grasslands (SNG) are essential in the context of farmland biodiversity. The Common Agricultural Policy (CAP), on the other hand, is an important tool for the continuation of the management of semi-natural grasslands. Explicit knowledge on the pattern of grassland area changes is important to foster a more effective use of CAP for grassland biodiversity conservation. Our aim was to determine the habitat-specific changes in the distribution of Latvian SNG across different management regimes. Based on state-owned geospatial data of SNG distribution in 2014 and 2022, we assessed changes in semi-natural grassland areas over nearly ten years by analysing grassland management and spatial distribution including areas inside and outside the Natura 2000 network. The spatial distribution of SNG remained similar in both periods. Eastern Latvia retained the highest share of SNG while the central part showed the most pronounced increase in new localities of SNG due to extensive habitat mapping carried out in recent years. Abandonment appeared as a more important threat to SNG in the Natura 2000 network and more profoundly to unproductive habitat types while transformation into arable land and grassland intensification was a considerable threat to SNG outside the network and to more productive habitat types. We suggest that agri-environment schemes should address the different needs of SNG in the Natura 2000 network and outside it.
