Brunisols include Udolls and Udepts with good drainage and
Aquolls and Aquepts with imperfect drainage.

Conclusions
More than three-quarters (79%) of the soils of the Great
Lakes Coastal Zone have been identified, classified, and
mapped. Soil Taxonomy (US) and The Canadian System of
Soil Classification have been to classify the soils of the
region. Whereas ST is a global system, the Canadian
approach is strictly national. However, both schemes are
natural systems that delineate soils based on their properties
rather than their presumed genesis. Both systems are hierarchical, with ST having six levels and the Canadian system
having four. Both approaches map soil series and soil
associations. ST uses diagnostic horizons for taxonomic
levels; the Canadian system employs genetic and some
diagnostic horizons. Whereas ST uses formative elements to
build soil taxonomic names, the Canadian system employs
two levels of word modifiers. The two systems are somewhat
comparable. Difficulties in comparing the two soil classification systems center primarily on two Canadian orders—
the Gleysols and the Brunisols. Gleysols include Aquolls,
Aquepts, and Aquents saturated by water from below (Endo) or from above (Epi-) in ST. Brunisols include Udolls and
Udepts under good drainage and Aquolls and Aquepts under
imperfect drainage.
