Soils in Canadian Ecozones
Canadian System of Soil Classification
Many different classification systems can be developed for the same group of objects. The Canadian System of Soil Classification is a scientific classification based on the natural relationships between soils and on characteristics that are important and precise. Five taxa are recognized in the hierarchical scheme used for the Canadian System of Soil Classification:

Orders differentiated on the basis of characteristics of the soils that reflect the nature of the total soil environment and the effects of the dominant soil forming processes
Great Groups differentiated on the basis of characteristics that reflect the differences in the strengths of the dominant processes or a major contribution of an additional process
Subgroups differentiated on the basis of the kind and arrangement of horizons that reflect a conformity to the central concept of the Great Group, a gradation towards another soil Order, or the presence of a special horizon
Family differentiated on the basis of the parent geologic material characteristics such as texture, mineralogy, depth, and/or reaction and on differences in soil climatic factors
Series groupings of pedons with similar arrangements of horizons whose color, texture, structure, consistence, thickness, reaction, and composition fall within relatively narrow and well defined ranges
