Abstract: In the context of dynamic socio-economic development and globalization of the economy, modern society places higher requirements for optimal use of the various forest resources. The need to preserve the integrity of forest ecosystems and maintain a sustainable balance between all forest functions implies improvement of the forest management systems. In the forest planning process, it is expedient to prepare scenarios for multifunctional forest management with the help of Sibyla, decision-making support information system partially adapted for use in Bulgaria. Sibyla is a growth simulator that, on the basis of mensuration data, as well as of planned forestry treatments, generated a model development of forest plantations in Jenda State Forestry and Hunting Enterprise in Kardzhali Municipality for a period of 50 years. An analysis of the results has been carried out using the following indicators: total volume of the standing wood, potential yield by wood volume and grade and total biomass production under different forest management regimes in the selected plots. The results obtained provide a good basis for revealing the opportunities for achieving integrated forest management in Jenda State Forestry and Hunting Enterprise in Kardzhali Municipality.
