This biotope is a mixed peat-bog extending partly over the saddles and partly over the slopes of the mountain range of the upper Val di Non. The vegetation is typical of the plain aquifer peat-bogs and of the high peat-bogs of transition (very wide and well-kept sphagnum bogs); on the external edge, there is a zone of mugho pine and a more restricted zone of Norway spruce, both on peat (wooded peat).
