The change in the use of agricultural and forestry land for other purposes is the natural process of rural areas urbanisation. In municipalities located nearby big cities this transformation is inevitable and indeed desirable, while in municipalities located close by protected areas is a symptom of negative processes, especially from an environmental perspective. Moreover, such transformations have many other economic and social consequences which are worth to pay special attention to. This paper is an attempt to determine what is the level of negative changes introduced in the planning documents in municipalities located within the borders of National Parks. The indicator analysis based on statistical data of local date bank [BDL] in the fields of local government and spatial planning was conducted. The analysis enabled to present the differences between municipalities with very high natural values in terms of decreasing the area of agricultural and forestry landscape. Furthermore, to elaborate the typology of the studied administrative units the obtained results were verified by comparing them with recommended percentage share of forest and agricultural lands which potentially will guarantee good conditions for the development of tourism in rural municipalities.
