These are coniferous forests dominated by Abies alba with frequent occurrence of Picea abies. The herb layer is composed of generalist species of mesotrophic forest soils, nutrient-demanding species and acidophytes. This vegetation type is associated with cambisols developed over gneiss, granite, flysch sediments and other soil and bedrock types. These forests developed from natural fir-beech forests under the impact of forest grazing, litter raking and selective logging. Beech is currently spreading and replacing fir in some parts of the range of this association. In the Czech Republic these forests are most common in south-western Bohemia and north-eastern Moravia, but also occur elsewhere at mid-altitudes.
