In spruce monocultures on Pohorje mountain range underplanted beech seedlings were analysed with izozyme genetic markers. Genetic variability was estimated on 17 polymorphic gene loci. Our results do not support the hypothesis on a common source of the used forest reproductive material for under-planting. A proposal for an expansion of the network of forest gene reserves of beech aimed for change of spruce monocultures on Pohorje was defined.

Changes of environmental conditions and silvicultural practices strongly affect evolutionary forces, leading to changes in the patterns of genetic diversity. To assist conservation and management of genetic diversity of forest tree populations, thus enabling continuous adaptability of forest tree populations to future environments, it is becoming increasingly important to monitor consequences of environmental changes and intended or unintended anthropogenic influences on populations. Genetic monitoring, also mentioned instrategic European and national documents, is a system that enables quantification of temporal changes in population genetic matrices or other population data. Its main objective is to answer the question whether populations can ensure sustainable development of the existing forest. Development of genetic monitoring system must include a definition of a robustas well as labour and financially feasible sampling and experimental design.
