ECO-GEOGRAPHIC CRITERIA FOR MAPPING FOREST HABITATS IN SOUTHEASTERN MANITOBA

Eco-geographic criteria for forest habitat mapping in southeastern Manitoba are presented in form of (a) an air-photo orientation key that is intended for making preliminary type lines on standard (1:15,840) air photographs and (b) a field key that can be used for checking the type lines and for independent field mapping. The ecological relations of the habitat types are summarized by tabulation (Table 1) and by a profile diagram showing the habitat types as generalized ecological series (Fig. 1).
