The material in this tier establishes in whole or in part the subgroup classification. Three kinds of fibric horizons are named: 1) Fennic horizons are derived from rushes, reeds, and sedges; 2) Silvic horizons are derived from wood, moss with less than 75% of the volume composed of sphagnum spp., and other herbaceous plants; and 3) Sphagnic horizons are derived from sphagnum mosses. Ed. they are found in the coastal rain forests where precipitation levels can reach 3000 mm per year, and great thicknesses of leaf litter and woody forest material accumulates.

Histic subgroupSoils of this subgroup are dominated by F or H horizons and are directly underlain by a O horizon greater than 10 cm. Humic material usually is classified on the van Post scale of decomposition as class 7 or higher and rarely as class 6.

Organic soils in these regions are commonly referred to as peats, bog or fen soils, or mucks. The placement of wetland organic soils into the three main great groups of the Organic order depends on depth relationships of the organic layers within the control section. Fibric material has undergone relatively little decomposition and most of the plant material can be readily identified as to its botanical origin. In the mineral soils, organic matter content may vary from 0-20 per cent. Soils of the Organic order are the dominant wetland soils found in forested regions of Canada but they also occur in non-wetland positions in upland sites where leaf litter accumulates.
