Representation
Ecological Representation - conserving some of everything
Canada’s nature is diverse; our protected and conserved areas network needs to represent that diversity.
Canada reports the amount of area conserved in each of 18 different ‘ecozones’ through the Canadian Environmental Sustainability Indicators (CESI) program. Ecozones are large, very broad areas of the Earth’s surface defined by both living and non-living features. Examples of ecozones are the Prairies, Boreal Shield and Hudson Plains.
‘Ecoregions’ are smaller areas that reflect the variability that occurs within an ecozone. There are 215 terrestrial ecoregions in Canada. Examples of ecoregions include Mixedgrass Prairie, Avalon Forest (in the Boreal Shield), and Coastal Hudson Bay Lowlands.
The Pathway National Advisory Panel recommended that ecological representation be evaluated at the ecoregion level. Measuring Canada’s progress at the ecoregion level, as well as the ecozone level, will help us conserve some of everything.
Canadian Terrestrial Ecological Framework
The Canadian Terrestrial Ecological Framework (CTEF) contains the updated spatial and attribute data on ecozones and ecoregions in Canada as of 2019. While not an official update to Canada’s ecoregions, the CTEF has been developed to support national reporting on ecological representation under the Pathway to Canada Target 1 initiative. It is compiled and managed by Environment and Climate Change Canada (ECCC), in collaboration with provincial and territorial jurisdictions. The CTEF is an ESRI™ geodatabase with a Canada Albers Equal Area Conic geographic projection. In addition, the geodatabase has been aligned to Canada's coastlines as defined by the Topographic Data of Canada - CanVec Series at a scale of 1: 1,000,000. While this coverage contains the most recent information available from jurisdictions at the time of compilation, all parties interested in using this layer should note that jurisdictions use different methodologies. The national data layer harmonizes these products by adjusting ecoregion boundaries at political boundaries, however; please refer to the data provided on the appropriate provincial or territorial website for the methodology used to define ecoregions in each jurisdiction.
