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 research is to find out the causes of emergence of uninhabited dwelling houses, to state the criteria of their defining and identification, to work out possible solutions for improvement of the situation. The information from the Central Statistical Bureau, the data from the census of 2011 and the information about buildings or slums gathered by the local municipalities have been used in the research. As a result, the classification of uninhabited buildings and recommendations have been worked out.
