Ecosystems of Ontario, Part 1: Ecozones and Ecoregions

Summary

Ecological Land Classifi cation (ELC) systems are used to classify and describe ecosystems. Ecosystems are recognizable because of unique interactions (functions) among the components (composition) and the patterns (structure). Organized into a spatial framework, ecosystems can be defi ned and characterized on the basis of common features such as bedrock geology or climatic features, which set them apart from other units. Ecosystem classifi cation delineates areas of similar ecology at different scales, often within a nested or hierarchical framework. In Ontario, Angus Hills developed the fi rst comprehensive, multi-scale, hierarchical ELC describing ecosystems at two scales, distinguished by climatic patterns, physiographic differences and successional trends exhibited by the predominant vegetation type on those physiographic features (Hills, 1959). Subsequently, he revised the system as new information became available (see Hills, 1961, 1964, 1976) and demonstrated how the system could be used to provide a broad-scale ecological context for resource management and planning activities in Ontario.
