ENIn Lithuania, as in other analyzed countries, greatest attention is concentrated on the protection and monitoring of state forests, while the situation in the private forest sector is quite unclear and uncertain. In most European countries, as well as in Lithuania, there are a lack of socio-economic data, and there are no planned forest monitoring methods and permanent programs. We claim that the problem of achieving sustainability in the forest sector, in the case of the estates of the private forest owners, could be partially solved by implementing the monitoring of social and economic indicators. This study proposes the need for the establishment of a social and economic database of private forest owners in Lithuania. In this article, we have carried out a detailed analysis of scientific sources and selected socio-economic indicators to help the adoption of optimal management solutions for sustainability in the private forest sector. To explore the need to establish a social and economic database of private forest owners in Lithuania, we conducted an empirical study by applying the method of semi-structured interview to a group of experts/specialists in the forestry field. Summarizing the results of the research, it can be concluded that the need for socio-economic information about the owners of private forests in Lithuania is obvious, as it would clarify the most pressing problems that forest owners face when farming in their forest estates. This information would also allow the improvement of policy formulation and implementation, the adoption of legal regulations, and the organization of the necessary changes in private forestry. Therefore, it is necessary to establish criteria and indicators that could ensure more sustainable forest management. Keywords: private forest owners; legal data of private forests owners; social and economic indicators. [From the publication]
