In order to preserve protected areas and to reduce their devastation, it is important to know the most common violations of these areas. The created map will provide the information about areas where the damage occurs most often. The Nemunas Loops Regional Park was selected for the research, the main aim of which was to identify the most common violations and the most problematic areas. The objectives of this research were to carry out a detailed analysis of violations in the Nemunas Loops Regional Park and protected areas for 2007- 2014 period of time and to create a dot distribution map of these violations. The main tasks were the following: 1) to review the aim of the Nemunas Loops Regional Park establishment, prohibited and promotional activities, 2) to carry out the classification of violations in these areas during 2007-2013 according to the Code of Administrative Offences of the Republic of Lithuania, 3) to group the violations of 2007-2013 according to the timing and to create a dot distribution map in order to provide its application possibilities. The study led to the following conclusions: most violations were made contrary to the requirements of the protected areas (Clause 76). For instance, arbitrary constructed mobile homes, environmental pollution, violations of visiting regime in the nature reservation, water protection requirements (Clause 55), parking a car in the protected area of the water reservoir, agricultural land, storing agricultural equipment which is not used etc. The map highlights the most problematic areas where violations occur every year. These are: Punios Šilas Strict Nature Reserve and the areas around it, Pociūnai and Balbieriškis towns, Birštonas. In 2014 the form of reports was changed and it was not possible to analyse the violations in detail. It was a negative factor for this research because no accurate violations and areas could be recorded. For this reason the map was not created. 230 various violations happened in the Nemunas Loops Regional Park during the period of 2007-2014. The created map can be used as an additional measure for prevention of violations.

The aim of the article is to analyse the land use of selected areas and its impact on the ecological condition of the area. 3 (Ignalina, Molėtai and Zarasai) from 15 districts (which are characterized by considerable forest cover and exceptional recreational characteristics) of Lithuania were selected as the object of research. The largest part of the area of these districts (44–57%) consists of agricultural areas; a slightly smaller area (32–42%) is occupied by forests and other natural areas. Artificial covers occupy from 8 to 11 percent of the total area of districts. Analysing the change of these land cover areas over a period of 12 years, a practically stable (4-6%) decrease of agricultural areas and growth of forests and other natural areas (3–5%) as well as artificial covers (1%) in all three municipalities are observed. Taking into account the prevailing land cover structure in the districts in 2018, the estimated degree of polarization of all districts/ecological stability indicator of the area exceeded 0.67, i.e., areas have been found to be ecologically stable. However, after assessing the ecological stability of the surveyed areas using a multi-criteria analysis method and introducing more criteria influencing the ecological condition of the area, not only the land cover structure, it was found that the ecological condition of Molėtai district is still the worst according to the ranking indicators, while that of Zarasai and Ignalina districts is very similar. Such a negative multi-criteria assessment of the ecological condition of Molėtai district was influenced by all criteria: lower area of protected and natural territories, forests in the district, higher population density, road length, area of artificial covers and emissions (carbon monoxides, nitrogen oxides, etc.) quantity. Meanwhile, when assessing the ecological condition of Ignalina district, 4 criteria were favourable, namely: relatively low population density, road length, and lower emissions of gases and liquids, carbon monoxide, and for Zarasai district 7 criteria: higher areas of protected territories, forests and other natural, agricultural areas as well as artificial cover areas and lower population density, emissions of nitrogen oxides, gaseous and liquid substances. The results of the study unambiguously revealed that the ecological stability of the territory is influenced not only by the land use structure, but also by other environmental elements related to the area, therefore for full sustainable development, it is necessary to responsibly assess all possible factors influencing the ecological condition of the area.

Analysis of the condition of the Agila Dune is presented in this Article. The analysis is based on data collected during accurate geodetic measurements using LIDAR technology. The current state of the Agila Dune was compared to the data of the previous year's LIDAR points in order to ensure the reliability and value of the research. In the course of the study, eleven cross sections were compared by height differences with previous year‘s measurements. The condition of the Agila Dune was found to be the worst in three cross sections. First cross section‘s erosion measured at 13,98 meters, erosion in the fifth cross section – 9.90 meters, and erosion in the eighth cross section – 11.34 meters. The main reasons for the deterioration of the natural values of the Kursiu Nerija National Park are climate, wind, high visitor flows and the persistent failure to carry out comprehensive research. Therefore, in order to preserve these unique natural values, it is important to collect large-scale and high-precision data on the status of these values, to systematize, to analyse and take appropriate protective measures.

The need for recreational territories in urban areas has recently become increasingly relevant. In order to create and develop an effective urban green space system, it is necessary to study its main structural components. The aim of the research is to perform the analysis and evaluation of recreational territories of Biržai town. During the research, the territory of Biržai town, green spaces were analysed, the main cadastral data of recreational territories as real estate objects were determined: areas, land use purposes, land use types, special land use conditions and easements. The influence of cadastral indicators in adapting objects to recreation and tourism has been determined. Possibilities of recreational activities in Biržai town were evaluated. Following the SWOT, a generalized analysis of the situation was provided. The performed research revealed that the town of Biržai is dominated by built-up and water-occupied territories. The areas of the territories intended for recreation do not correspond to the areas provided for in the Master plan of Biržai town. The green space system is uneven; the recreational territories do not ensure a full life for the townspeople. The town lacks green spaces adapted to various activities, and the integration of water bodies into the urban living environment is moderate. It is proposed to activate communities in the development of living environment in Biržai.
