Genetic diversity is required as a basis for adaptability of forest tree populations under changing environmental conditions. Adaptation to extreme environments may lead to a short term genetic optimum, on the long run, however, to loss of diversity. The aim of this study was to estimate the amount of variation in spruce stands at the Schulterberg area. Isozyme analysis was employed to investigate three stands along an altitude transect. Although the number of polymorphic loci decreased at higher altitudes, no striking differences were found with respect to gene diversity. There is no indication of reduced adaptability in the marginal area close to the forest line.
