Ecozones and ecoprovinces of Canada, 2017

Canada is divided into 15 ecozones, forming the country's first level of ecological land classification. They represent areas of the earth's surface representative of large and very generalized ecological units characterized by interactive and adjusting biotic and abiotic factors. These 15 ecozones can be further subdivided into 53 ecoprovinces, 194 ecoregions, and 1,027 ecodistricts.[1]

History

In 1995, Agriculture and Agri-Food Canada, Environment and Climate Change Canada, and the Commission for Environmental Cooperation established the 15 terrestrial ecozones, 5 marine ecozones, and 194 ecoregions of Canada to provide an spatial framework for the research, assessment, and monitoring of ecosystems and ecosystem components across North America. A second report published in 1999 established the 53 ecoprovinces of Canada.[1]

On November 20, 2017, Statistics Canada approved the Ecological Land Classification (ELC) framework as the official government standard in classifying the ecological regions of Canada. This framework mirrors that which was originally established in 1995, but increases the number of ecodisiricts to 1,027 in order to better align them with the Soil Landscapes of Canada (SLC) database of Agriculture and Agri-Food Canada. Though this framework originally included 5 marine ecozones, these were never formally adopted by Statistics Canada.[1]

Marine ecozones

The Canadian marine ecozones adjoin to each other, except for the Pacific ecozone which is adjacent to international marine ecozones and terrestrial Canadian ecozones. The largest is the Arctic Archipelago, which actually extends to subarctic regions.

Ecozone Area (km²)

Total 2,788,349 5,543,913 37.7 100.0

Terrestrial ecozones

Canada is divided into 18 terrestrial ecozones covering a total area of 9,891,584 km2 (3,819,162 sq mi).[2]

Ecozone Area (km²)[2] Percent total area[2] Percent protected (2019)[2]
