The article deals with Norway spruce (Picea abies), silver fir (Abies alba) and larch (Larix decidua) forests of the orders Piceetalia and Athyrio-Piceetalia (Vaccinio-Piceetea) in Slovenia. A total of 934 releves of spruce, larch and fir forests within the Piceetalia and Athyrio-Piceetalia were collected from the literature. After resampling, 319 releves remained, originating from 28 associations. Classification revealed two major groups of spruce, larch and fir forests, one thriving on non-carbonate bedrock and the other on carbonate. We further divided forests on non-carbonate substrate into two major groups - one thriving at high altitudes and the other in lowlands, both assigned to Piceion abietis. The second major group contains mesophilous, species-rich communities found mostly on carbonate bedrock. This major group can be further divided into four groups. The group of secondary forest on sites of beech forests, as well as the group of forest found in frost hollows can be assigned to Abieti-Piceion. The group of herb-rich, mesophilous communities forming zonal spruce and larch forests can be assigned to Chtysanthemo-Piceion and the group of forests on boulder scree to Calamagrostio-Abietion. Analysis of structural, functional, phytogeographical and geomorphological features, as well as ecological conditions estimated by bioindicator values, demonstrated the usefulness of this classification.
