Rila-Pirin region is one of the location and preservation centres of natural coniferous forests on Balkan Peninsula. The pure and mixed stands formed by Pinus nigra Arn., Abies alba Mill., Pinus sylvestris L., Fagus sylvatica L., Picea abies L.,Karst., Pinus peuce Grieseb., Pinus heldreihii Christ., Pinus mugo Turra are with high productivity, good vital status and regeneration, which determines their importance as a standard of growth, development, normal structure and stability of composition of all the complex anthropogenically adapted forest ecosystems in the region. The data were obtained in 37 permanent and temporal sample plots located in the range of 1180 to 2010 m a.s.l. on slopes with different exposure and different edaphic conditions. An ecological and silvicultural characteristic of the natural coniferous dendrocoenoses was established. The contemporary dendrometric parameters were obtained as well as the sortiment structure of the biomass stored according timber categories. Section: Relic populations in the refugium area
