Critical habitat is identified for species listed as Endangered or Threatened under the federal Species at Risk Act (SARA) and where federal critical habitat protection orders are in effect. Fisheries and Oceans Canada (DFO) is the responsible authority for the protection, recovery and conservation of all listed aquatic species at risk in Canada. Critical habitat is defined as the habitat that is necessary for the survival or recovery of a listed wildlife species and that is identified as such in the recovery strategy or action plan for the species (https://www.canada.ca/en/environment-climate-change/services/species-risk-public-registry.html). SARA makes it illegal to destroy any part of the critical habitat of a listed species and may impose restrictions on development and construction. Species in this layer have federal protection of critical habitat under a Critical Habitat Order pursuant to subsections 58(4) and (5) of SARA, which brings into force the subsection 58(1) prohibition against the destruction of any part of critical habitat. This dataset delineates an area or extent in which the species and its critical habitat may be found. Exterior extent polygons are derived from the detailed data provided in DFO's Fisheries and Oceans Canada Species at Risk dataset, reproduced under the Open Government Licence - Canada. Alberta Environment and Protected Areas Fish and Wildlife Management Information System (FWMIS) Hydrology Arc and Polygons data, and a surrounding larger buffer. This dataset communicates to users the following information: the proximity of aquatic critical habitat. the prohibition against the destruction of any part of aquatic critical habitat. directs users to DFO to ensure compliance with federal legal instruments. and ensures that any activities which may result in the destruction of critical habitat are managed to the extent required under SARA. Users must consult Fisheries and Oceans Canada (Projects Near Water webpage: www.dfo-mpo.gc.ca/pnw-ppe/index-eng.html. Fisheries Protection Program: FisheriesProtection@dfo-mpo.gc.ca) in relation to the application of the Species at Risk Act and published Critical Habitat Orders (SARA Public Registry).

The Species at Risk (SAR) Program is responsible for carrying out DFO’s mandate under the Species at Risk Act (SARA) to protect, recover and conserve all listed aquatic SAR in Canada. Critical habitat is identified for species listed as Endangered or Threatened under the Species at Risk Act (SARA). This mapping tool is for general guidance only. “Mapped” representations of waterbodies and watercourses are based on authoritative provincial geospatial products, guidance and standards. Due to the nature of dynamic systems and the resolution/accuracy of these data sets, areas within which critical habitat is found as displayed on the mapping tool may not align exactly with natural watercourses. If discrepancies occur, refer to the relevant species recovery strategy and/or action plan for additional information on critical habitat. If additional guidance is required, please contact the Fish and Fish Habitat Protection Program: https://www.dfo-mpo.gc.ca/pnw-ppe/contact-eng.html Critical habitat is defined under section 2 of SARA as: "the habitat that is necessary for the survival or recovery of a listed wildlife species and that is identified as the species' critical habitat in the recovery strategy or in an action plan for the species". Section 49(1)(a) of SARA requires that a species' Recovery Strategy/Action Plan include an identification of the species' critical habitat to the extent possible, based on the best available information, including information provided by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). SARA makes it illegal to destroy any part of the critical habitat of SAR and may impose restrictions on development and construction. Critical habitats were assembled by SARA regional biologists and recovery teams. They are designed to support the protection and recovery of species listed as Endangered or Threatened under the Species at Risk Act. They are also described and displayed in species' Recovery Documents and Action Plans.

This dataset displays the geographic areas within which critical habitat (CH) for terrestrial species at risk, listed on Schedule 1 of the federal Species at Risk Act (SARA), occurs in Canada. Note that this includes only terrestrial species and species for which Environment and Climate Change Canada (ECCC) and Parks Canada Agency (PCA) lead. Under SARA, critical habitat is “the habitat that is necessary for the survival or recovery of a listed wildlife species and that is identified as the species’ critical habitat in the recovery strategy or action plan for the species.” To precisely define what constitutes critical habitat for a particular species it is essential that this geospatial information be considered in conjunction with complementary information provided in a species’ recovery document. Recovery documents are available from the Species at Risk (SAR) Public Registry (https://www.canada.ca/en/environment-climate-change/services/species-risk-public-registry.html) for two posting stages (proposed and final posting). The recovery documents contain important information about the interpretation of the geospatial information, especially regarding the biological and environmental features (“biophysical attributes”) that complete the definition of a species’ critical habitat. Within any defined critical habitat geospatial boundary, not all of the area is necessarily critical habitat. It is important to note that recovery planning documents (and, therefore, critical habitat) may be amended from time to time as new information becomes available, which may occur after a document has been posted as proposed or final on the SAR Public Registry. The SAR Public Registry should always be considered as the main source for critical habitat information. In cases where the data are sensitive, the geographic area within which critical habitat occurs may be represented as grids. These are coarse grids (1, 10, 50 or 100 square kilometres) that serve as indicators to locate critical habitat in the recovery planning document. More detailed information on critical habitat may be made available on a need-to-know basis by contacting Environment and Climate Change Canada – Canadian Wildlife Service at ec.planificationduretablissement-recoveryplanning.ec@canada.ca. The data is current as of the date of the most recent revision.

The Endangered Species Act (ESA) requires the Federal government to designate critical habitat, areas of habitat essential to the species' conservation, for ESA listed species. This dataset is a compilation of the NOAA National Marine Fisheries Service and the U.S. Fish & Wildlife Service designated critical habitat in coastal areas of the United States. Critical habitat is defined as: (1) Specific areas within the geographical area occupied by the species at the time of listing that contain physical or biological features essential to conservation, which may require special management considerations or protection; and (2) specific areas outside the geographical area occupied by the species if the agency determines that the area itself is essential for conservation. See metadata for online linkages to reference full listings of proposed and final critical habitat areas.

Critical habitat is habitat needed to support recovery of listed species. When a species is listed under the Endangered Species Act, NOAA Fisheries is required to determine whether there are areas that meet the definition of critical habitat. Once critical habitat is designated, other federal agencies consult with NOAA Fisheries to ensure actions they fund, authorize, or undertake are not likely to destroy or adversely modify the critical habitat. Critical habitat is defined as: Specific areas within the geographical area occupied by the species at the time of listing that contain physical or biological features essential to conservation of the species and that may require special management considerations or protection; and Specific areas outside the geographical area occupied by the species if the agency determines that the area itself is essential for conservation.
