Profile ZT6, Cryic Rego Gleysol* (Appendix I : Table 26)
L-H- 23 to 0 m, dark brown (l0YR 3/3, moist), undecomposed sphagnum
peat with a thin layer of dark brown to black cladonia forest
peat ; extremely acid ; clear, wavy boundary .
Cyg- 0 to 29 cm, very dark gray (5Y 3/1, moist), loam ; cryoturbed ;
intrusions of organic material, organic stains and smears ;
slight build-up of organic matter in the lower portion of this
horizon ; weal-, medium subangular blocky ; slightly sticky,
slightly plastic ; friable when moist, slightly hard when dry ;
medium acid ;, abrupt, wavy boundary .
Cygz- 29+ cm, frozen cryoturbed loam ; slight build-up of organic
matter in the top of this horizon ; vein ice, ice crystals ;
ice content approximately 50 percent .
Topography :
Gleysolic soils have developed on all of the poorly drained
materials mapped iri~the study area .
The topography is flat to gently
sloping on lacustrine deposits and moderately to strongly sloping on
hillsides and high mountain plateaus .
Vegetation :
Black spruce dominates these soils along with birch and larch .
The shrub and herb layers indicate a transition to peatland .
Potentilla fruticosa and Betula glandu losa are the most common tall
shrubs present with the dwarf shrubs being Ledum groenlandicum ,
Vaccinium spp . and Empetrum nigrum . The herb layer is dominated by
feather mosses and Spha num fuscum .
Physical and Chemical Characteristics :
Most of the Gleysolic soils are shallow with various amounts of
surface peat .
These soils are slightly to medium acid and medium to
moderately fine in texture .
* Influenced by cryoturbation .
