In the beginning of the 20th century in BiH, more than 50% of all forests were virgin forests. Old forestry expert, engineer Julius Fröhlich, Who was in BiH at that time, noticed that poor lines of transportation and mountain water currents inconvenient for transportation of wood are major reasons why so many forests remained untouched. First forest administration in Bosnia was Sarajevska, with main office in Srednje. Forest road, 20 km long up to the mountain Ozren, served for export of 2000-3000 m3 of wood per year for Sarajevo, and 20 000 m3 of logs and up to 15 000 m3 of charcoal were transported by railway, for blast furnaces in Vares. Exploitation of forests and destruction of virgin forests, by converting them into commercial forests, was expanding fast. So today, very small areas of "natural" forests remained preserved. In the beginning that process was unplanned. Not until 1912, the first assessment of forests in BiH has been done, and after that elaboration of management plans has started. In Republic of Srpska three virgin forests remained preserved. Those are: worldwide known virgin forest "Perucica", "Janj" and "Lom". Soon, the elaboration of the Study for NP Sutjeska, where Perucica is, will start, while the elaboration of management plan for other two virgin forests is the subject of this report. Previous plans for virgin forests have not fulfilled multifunctional principles and European standards, because they neglected the ecological component. Two plans were elaborated for virgin forest "Janj", more exactly forest management plans: first one for the period from 1966 to 1975, and second from 1976 to 1985. For virgin forest "Lom" separate management plans were not elaborated, but within elaboration of forest management plans, virgin forest has been distinguished into special management class. Fate of the two virgin forests has been threatened by the decision of the Executive Council of BiH (in 1960 for "Janj", and in 1962 for "Lom"), according to which both virgin forests were excluded from administration of Forestry Institute from Sarajevo, and given to local economic organizations for management. Those decisions planned to separate virgin forest "core" of 50-60 ha in both of them, while the remaining part of virgin forests area of 250 ha would be regularly managed. Panov and Fukarek (1967) expressed their regret in this way: "When that happens, we would observe the ecology on the small area of forests - areas surrounded from all sides with cut forest. No doubt that even that would represent a great interest, but from now only Perucica will represent virgin forest, as a large area and area without outer influence". Fortunately these decision were only partly realized, so virgin forest "Janj" and "Lom" remained preserved on the entire area. This plan sould establish actual conditions of these forests and forests measures for their preservation and improvement.
