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 “Terrestrial Ecoprovinces of Canada” dataset provides representations of ecoprovinces. An ecoprovince is a subdivision of an ecozone and is characterized by major assemblages of structural or surface forms, faunal realms, and vegetation, hydrology, soil, and macro climate. For example, the Newfoundland ecoprovince (no. 6.4) is one of six ecoprovinces within the Boreal Shield Ecozone

The National Ecological Framework for Canada's "Land and Water Area by Province/Territory and Ecozone” dataset provides land and water area values by province or territory for the Ecozone 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 "Elevation by Ecozone” dataset provides elevation information for ecozone framework polygons, in meters. It includes codes and descriptions for minimum elevation, maximum elevation, mean elevation and the difference in elevation.

The National Ecological Framework for Canada's "Surficial Geology by Ecozone” dataset contains tables that provide surficial geology information with the ecozone 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 "Surface Form by Ecozone" dataset contains tables that provide surface form information for components within the ecozone 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 "Landform by Ecozone” series contains tables that provide regional landform information for components within the ecozone 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.

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

The Environmental Studies Research Fund (ESRF) Regions are legally described in Part I and Part II of the Schedule in the Environmental Studies Research Fund Regions Regulations in the Canada Petroleum Resources Act. This data collection is for illustrative purposes only and includes:• 1 dataset illustrating ESRF prescribed regions 1 to 31 as they are described in the ESRF Regions Regulations.• 1 dataset illustrating the areas where levies are no longer applied to ESRF prescribed regions. These areas include lands that are described in the ESRF Regions Regulations but have since been devolved to the Government of Yukon or the Government of Northwest Territories as part of the 2003 Yukon Devolution and 2014 Northwest Territories Devolution, respectively. Once the Yukon Act and Northwest Territories Act came into effect, lands subject to devolution were no longer considered frontier lands or Canada lands, and therefore no longer subject to ESRF levies under the Canada Petroleum Resources Act. The geospatial extents used in this dataset represent those identified in the Devolution Agreements. Future updates to Part II, section 3 of the Schedule in the ESRF Regions Regulations will reflect the Yukon and Northwest Territories Devolutions.• 3 maps (National, North, South).• 1 table compiling the historical levies for each ESRF prescribed region.Context:The Environmental Studies Research Fund (ESRF) is a research program which sponsors environmental and social studies designed to assist in the decision-making process related to oil and gas exploration and development on Canada's frontier lands. The ESRF is directed by a 12-member Management Board which includes representation from the federal government, the Canada-Newfoundland and Labrador Offshore Petroleum Board (C-NLOPB), the Canada-Nova Scotia Offshore Energy Regulator (CNSOER), the oil and gas industry, and the public. The ESRF is administered by a secretariat which resides in the Offshore Management Division in Natural Resources Canada.Since 1987, the ESRF has received its legislative mandate through the Canada Petroleum Resources Act. The ESRF regions are described in the Environmental Studies Research Fund Regions Regulations. As well, the Canada-Newfoundland and Labrador Atlantic Accord Implementation Act and the Canada–Nova Scotia Offshore Petroleum Resources Accord Implementation and Offshore Renewable Energy Management Act provide legislative direction in the southern ESRF regions.Funding for ESRF is collected annually through levies paid by lease-holding oil and gas companies active in a specific ESRF region. In accordance with the legislation, levies are recommended by the Management Board to the Ministers of Natural Resources and Crown-Indigenous Relations and Northern Affairs for approval. Levies in the southern regions in areas governed by an offshore Accord are subject to final approval by the respective offshore regulator (i.e., the C-NLOPB, or the CNSOER). Levies are calculated by multiplying the levy rate of a region by the number of hectares of land under lease.The ESRF has sponsored studies on biodiversity; environmental effects and monitoring; social and economic issues; ice, icebergs, and ice detection; oil spill research and countermeasures; sea bottom ice scour; sediment transport; Indigenous Knowledge; and waves.

Ecologically and Biologically Significant Areas (EBSAs) are areas within Canada's oceans that have been identified through formal scientific assessments as having special biological or ecological significance when compared with the surrounding marine ecosystem.Failure to define an area as an EBSA does not mean that it is unimportant ecologically. All areas serve ecological functions to some extent and require sustainable management. Rather, areas identified as EBSAs should be viewed as the most important areas where, with existing knowledge, regulators and marine users should be particularly risk averse to ensure ecosystems remain healthy and productive.Why are EBSAs identified?EBSA information is used to inform marine planning, including environmental assessment and the siting of marine-based activities, by:- Informing and guiding project-specific or regional environmental assessments;- Informing and guiding industries and regulators in their planning and operations, for example: EBSAs have been acknowledged and referred to (often as "Special Areas" or "Potentially Sensitive Areas") in oil and gas related assessments;- EBSA information has been provided to proponents of submarine cable projects to be used for route planning purposes;- Informing and guiding Integrated Oceans Management (IOM) process within five Large Ocean Management Areas (LOMAs) and twelve marine bioregions;- Serving as a basis for the identification of Areas of Interest (AOIs) and of Marine Protected Areas (MPAs) (individually and in the context of planning bioregional networks of MPAs).How are EBSAs identified?The process used to identify EBSAs is generally comprised of two phases. The first phase involves compiling scientific data and knowledge of a marine area's ecosystems - notably fish species, marine mammals, sea birds, marine flora, marine productivity, physical and chemical conditions and geology. "Knowledge" includes experiential knowledge of long-time uses of the areas. In some cases (e.g., in the Arctic), substantial efforts are taken to collect traditional knowledge on ecosystems and environmental conditions from community members, fish harvests, hunters and individuals whose knowledge of the study area complement often helps fill scientific data gaps.In the second phase, the available information for a marine area (e.g. a bioregion) is assessed against five nationally-established science-based criteria including:- Uniqueness: How distinct is the ecosystem of an area compared to surrounding ones?- Aggregation: Whether or not species populate or convene to the study area?- Fitness consequence: How critical the area is to the life history of the species that use it (e.g. is it a spawning or feeding ground)?- Naturalness: How pristine or disturbed by human activities is the study area?- Resilience: What is the ability of the ecosystem to bounce back if it is disturbed?Progress to date and next stepsEBSAs have been identified for large portions of Canada's Atlantic and Pacific Oceans as well as most of the Arctic oceans. EBSAs will continue to be identified in priority areas as resources become available to carry out the process. The boundaries or locations of existing EBSAs may be modified to reflect both new knowledge and changing environmental conditions.
