The research is analysis of forest cadastre plots in Lithuania, which are not on forest land, but are covered with forest. The research was carried out in Dubrava regional division of the Lithuanian State Forest Enterprise. The study covers the forest districts of Ežerelis, Karmėlava, Padauguva, Sitkūnai and Vaišvydava. The main aim of the article is analysis of self-growing forest growth on non-forest land. Data from the Forest Cadastre of Lithuania (non-forest plots covered with forest) were used for the research. In this research were analysed orthophotographic maps of different periods (1995–2023), soil spatial data and other spatial data set. 135 non-forest land plots covered with forest in the Forest Cadastre, with a total area of 146 ha were found after analysing 5 forest districts. Reasons of self-growing is land abandonment, small plots sizes, less productivity of the land and lack of land reclamation.
