There are very few economically valuable forests in the karst region (about 22,000 ha) of which only 3,617 ha are accessible in high forests. According to the Law on Forests, karst is managed on the basis of a long-term, 10-year programme of management. In order to develop forestry in the area of karst, as well as to improve the condition of the forest fund, a special organizational unit, the "Centre for management of the karst" was established at the Public Enterprise "Sume RS" in Trebinje. The work of this Centre is based primarily on raising new cultures and providing maximum protection of the forest fund in the karst areas.
