The “Terrestrial Ecoregions of Canada” dataset provides representations of ecoregions. An ecoregion is a subdivision of an ecoprovince and is characterized by distinctive regional ecological factors, including climate, physiography, vegetation, soil, water, and fauna. For example, the Maritime Barrens ecoregion (no. 114) is one of nine ecoregions within the Newfoundland ecoprovince.

The National Ecological Framework for Canada's "Elevation by Ecoregion” dataset provides elevation information for ecoregion framework polygons, in meters. It includes codes and descriptions for minimum elevation, maximum elevation, mean elevation and the difference in elevation.

The “Terrestrial Ecodistricts of Canada” dataset provides representations of ecodistricts. An ecodistrict is a subdivision of an ecoregion and is characterized by distinctive assemblages of relief, landforms, geology, soil, vegetation, water bodies and fauna. For example, the Jeddore Lake ecodistrict (no. 473) is one of five ecodistricts within the Maritime Barrens ecoregion.

An ecoregion is an area with major physiographic and minor macroclimatic or oceanographic variation. There are 43 ecoregion in British Columbia of which 39 are terrestrial. Ecodivsions are meant to be mapped at 1:500,000 for regional strategic planning

The National Ecological Framework for Canada's "Surficial Geology by Ecoregion” dataset contains tables that provide surficial geology information with the ecoregion framework polygons. It provides codes that characterize surficial geology (unconsolidated geologic materials) and their English and French-language descriptions as well as information about the area and percentage of the polygon that the material occupies.

The National Ecological Framework for Canada's "Land and Water Area by Province/Territory and Ecoregion” dataset provides land and water area values by province or territory for the Ecoregion framework polygon, in hectares. It includes codes and their English and French descriptions for a polygon’s province or territory, total area, land-only area and large water body area.

The National Ecological Framework for Canada's "Surface Form by Ecoregion" dataset contains tables that provide surface form information for components within the ecoregion framework polygon. It provides surface form codes and their English and French-language descriptions as well as information about the percentage of the polygon that the component occupies. Surface form descriptions describe assemblages of slopes or recurring patterns of forms that occur at the earth's surface. When applied to consolidated materials (material that has been transformed to hard rock), it refers to the form produced after modification by geological processes. The mineral soil surface forms are: dissected; hummocky (irregular); inclined; level, rolling; ridged; steep; terraced; undulating. The wetland surface forms are: bog; fen; marsh; swamp.

The National Ecological Framework for Canada's "Soil Development by Ecoregion” dataset contains tables that provide soil development information for components within the ecoregion framework polygon. It provides soil development codes and their English and French-language descriptions as well as the percentage of the polygon that the component occupies. The soil development descriptions are based on the second edition of the Canadian System of Soil Classification (Agriculture Canada Expert Committee on Soil Survey, 1987).

Ecoregion - Seven New Brunswick Ecoregions delineate areas that are different with regard to climate (precipitation and temperature), based principally on elevation above sea level and marine influences.Ecodistrict - Ecodistricts are nested subdivisions of Ecoregions based on geomorphologic and lithologic differences. The correct way to quote an ecodistrict number is to quote both its ecoregion and ecodistrict numbers, separated by a dash, e.g.: 2-1 denotes the Upsalquitch Ecodistrict in the Northern Uplands Ecoregion.Ecosection - Ecosections are nested subdivisions of Ecoregions based on topographic and relief differences. The correct way to quote an ecosection number is to quote its ecoregion, ecodistrict, and ecosection numbers, each separated by a dash, e.g.: 2-1-3 denotes Ecosection 3 of the Upsalquitch Ecodistrict in the Northern Uplands Ecoregion.Ecosite - Ecosites capture individual landforms that in theory outline a single forest ecosystem type at the 1:50,000 mapping scale. They are more-or-less uniform with regard soil moisture regime, soil nutrient regime, and topoclimate. Within ecoregions, each ecosite may be presumed to have similar vegetation potential in terms of native species composition, forest cover type, and timber growth rate (although the situation on the ground often deviates from what is mapped due to mapping imprecision and/or vegetation disturbance). To most narrowly describe an ecosite’s landscape context, the correct way to label it is to quote its ecoregion, ecodistrict, ecosection, and ecosite numbers, each separated by a dash, e.g.: 2-1-3-7 denotes Ecosite 7 in Ecosection 3 of the Upsalquitch Ecodistrict (1) in the Northern Uplands Ecoregion (2).For more information, see Department of Natural Resources 2007.

The National Ecological Framework for Canada's "Landform by Ecoregion” series contains tables that provide regional landform information for components within the ecoregion framework polygon. It provides landform codes and their English and French-language descriptions as well as information about the percentage of the polygon that the component occupies. Regional landforms generally describe a region and include the various shapes of the land surface resulting from a variety of actions such as deposition or sedimentation (eskers, lacustrine basins), erosion (gullies, canyons), and earth crust movements (mountains). The regional landform classes are: plateau or tableland, hill and mountain, organic wetland, plain, scarp or valley.
