Luzulo-Abietetum is an association of Abies alba forests with admixed Picea abies, Pinus sylvestris and to a limited extent also with deciduous trees. Their shrub layer is poorly developed, while the species-poor herb layer is dominated by graminoids and in some places Vaccinium myrtillus or ferns. It occurs on nutrient-poor acidic rocks, on both gentle and steep slopes. Many stands probably developed from natural beech forests under long-term human impact.
