Abstract
Canada has defined a hierarchical classification of ecosystems.
At a simple level there are 20 ecozones, fifteen terrestrial and five marine.
An ecozone is an area of the earth’s surface that represents a large ecological
zone and has characteristic landforms and climate. Each ecozone is distinguished
from others by its unique mosaic of plants, wildlife, climate, landforms, and
human activities. Ecozones are useful for general national reporting and for
placing Canada’s ecosystem diversity in a North American or global context.
