This wooded peatland, dominated by Pinus rotundata, occupies shallow depressions in deep mires at least partially fed by oligotrophic ground water. Trees are sparse. The herb layer is poorer in species than that of the previous two associations. The moss layer is well developed and composed of different Sphagnum species. This association occurs in some mountain ranges of the Bohemian Massif and in the Třeboň Basin.
