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

This dataset is used for national and coarse-scale provincial reporting such as analyses of climate, demographics and watersheds.

Ecodomains are areas broad climatic uniformity, defined at the global level

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 “Terrestrial Ecozones of Canada” dataset provides representations of ecozones. An ecozone is the top level of the four levels of ecosystems that the National Ecological Framework for Canada defines. The framework divides Canada into 15 terrestrial ecozones that define its ecological mosaic on a sub-continental scale. Ecozones represent an area of the earth’s surface as large and very generalized ecological units. These units are characterized by interactive and adjusting abiotic and biotic factors.

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.

Ecodivisions are areas of broad climatic and physiographic uniformity, defined at the continental level.

This dataset provides treed area dynamics across Canada's 650 Mha forested ecosystems from 1984 to 2022, derived from Landsat-based annual land cover layers at a 30-m spatial resolution. It is developed within the framework of Canada’s National Terrestrial Ecosystem Monitoring System (NTEMS). This dataset identifies areas that remained treed, transitioned to treed (newly treed), or transitioned to other cover that is not treed vegetation (was-treed). The data enable national and regional assessments of long-term changes in treed area, capturing trends in treed area, post-disturbance recovery, and shifts in forest extent.When using this data, please cite as: Hermosilla, T., Wulder, M.A., White, J.C., Bater, C.W., Baral, S.K., Leach, J.A., 2025.

This dataset is a combination of landscape unit, biogeoclimatic zone/subzone/variants and Cariboo Chilcotin Land Use Plan (CCLUP) leading group type (PineGroup or FirGroup) used to roll up seral stage assessments in the Cariboo Natural Resource Region. Refer to the **Cariboo Regional Biodiversity Conservation Strategy Update Note #2: Amalgamation of Small NDT-BEC Units in Relation to Assessment of Seral Objectives and Old Growth Management Area Planning** and **Cariboo Regional Biodiversity Conservation Strategy Update Note #3: Definition of the Fir Group and Pine Group for Purposes of Seral Stage Assessments within NDT 4 of the Cariboo-Chilcotin** (see below under "Related Links") for more information on how seral stage assessment amalgamation units are derived.

The National Ecological Framework for Canada's "Land Cover by Ecoregion” dataset provides land cover information within the ecoregion framework polygon. It provides landcover codes and their English and French language description as well as information about the percentage of the polygon that the component occupies.
