The chapter presents information about in situ conservation of forest genetic resources in Bulgaria. The activities have resulted in establishment of many in situ units for gene conservation. A survey of all such object is done for 9 coniferous and 39 broad-leaved species. The units are classified into three categories: reserves, maintained reserves, and natural permanent seed production stands. The total number of the units is 6032 coniferous stands and 15,772 stands of broadleaved species. All they contribute to gene resources conservation and their sustainable use in forest trees in Bulgaria.
