The mapping of land capability for ungulates follows a national system developed with the aid of the Canadian Wildlife Service and the game branches of the provinces. The ungulate sector uses seven classes, like the others. In addition to class and subclass, the system indicates the ungulate species to which the classification refers. Capability for ungulate production implies a sufficient quantity and quality of food, protective cover, and space to meet the needs for survival, growth, and reproduction.

The land surface is mapped in homogeneous units based on physical characteristics significant to ungulates. The assignment of a class number to each land unit is based on known or inferred relevant information, including parent material, soil profile, depth, moisture, fertility, landform, climatic factors, and vegetation, which reflect the quality and quantity of food and cover available to wildlife. Classification is based on the natural state of the land under good practical and feasible wildlife management practices.

Capability mapping is accomplished through interpretation of air photographs and by field surveys. Location of the land, access to it, ownership, distance from cities or roads, and present condition of the land unit are not considered in assigning a capability class. Present cover and ungulate production in an area is used only as additional information. Excessive or insufficient hunting pressures do not limit the capability of the land and are not used in assigning classification values. Capability ratings are also established on the basis of the optimum vegetational stage (successional stage) that can be maintained with good wildlife management practices.

On the map above, capability classes are indicated by large numerals. The letters following the numeral indicate the subclasses (limitations). The letter beneath the numeral indicate the species to which the capability classification refers. On the above map, the species indication is M, E, and D, representing moose, elk, and deer, respectively. The colours of the map provide a quick reference to the classes.
