Fisheries and Oceans Canada Species at Risk Distribution (Range)
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. As part of this mandate, this spatial database has been developed to identify areas in which aquatic species listed under SARA may be found.Distribution and range information are identified for species listed as Endangered, Threatened or Special Concern under SARA.Distribution (range) polygons and lines were assembled by regional SARA biologists using the best available information, including COSEWIC status reports, recovery potential assessments, academic literature, and expert opinion. These spatial data support the protection, recovery and conservation of species listed as Endangered, Threatened or Special Concern under SARA. Species distributions are also described and displayed in Recovery Strategies, Action Plans and/or Management Plans. Discrepancies may exist between the distribution data shown in a species’ SARA recovery document and the current spatial data. Please contact DFO for more information on any data discrepancies.
Critical Habitat for Aquatic Species at Risk - Canada
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.htmlCritical 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.
Morrison Creek Lamprey Survey Data
Morrison Creek lamprey, Lampetra richardsoni variety marifuga are found only in Morrison Creek in Courtenay, BC. In 1995, this variety was designated Endangered by COSEWIC and is currently protected under the Species at Risk Act (SARA). For the years, 2011-2013 and 2015-2017, efforts were made to live trap Morrison Creek lamprey on and around spawning time. In 2014, DFO worked collaboratively with Hancock Forestry Management to assess the extent of the distribution of lamprey within the headwaters of Morrison creek on the land owned by the company. This dataset includes data for 2011 to 2017 inclusive.
Speckled Dace Critical Habitat Survey Data
Speckled Dace (Rhinichthys osculus) are listed under the Species at Risk Act (SARA) as endangered. These fresh water fish, of the family Cyprinidae, are found in Canada only in the Kettle Valley of British Columbia. Proposed critical habitat was based on minimum viable population analysis and assumed densities of fish. From October 19th to the 22nd of 2015, night time pole seining surveys were conducted to enumerate Speckled Dace in proposed critical habitat on the West Kettle River; one of three rivers containing Speckled Dace. The estimated population abundance of Speckled Dace within the survey area was 8,978 (6,143-11,814), however only 1,014 of these are estimated to be adults.
Critical Habitat for Species at Risk National Dataset - Canada
This dataset shows locations that contain critical habitat for certain terrestrial species at risk across Canada. It is intended to provide general guidance only, not legally authoritative boundaries.The dataset includes active critical habitat records for terrestrial species listed on Schedule 1 of the Species at Risk Act (SARA) as Endangered, Threatened, or Extirpated, as well as archived records for species whose status has been downlisted to Special Concern, and for which Environment and Climate Change Canada (ECCC) and/or Parks Canada are responsible.Under SARA, critical habitat means 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. These documents, which are published in the Species at Risk Public Registry (https://www.canada.ca/en/environment-climate-change/services/species-risk-public-registry.html), describe the critical habitat and may include maps or geographic coordinates.Because new information becomes available over time, recovery documents—and the critical habitat they identify—can be updated or revised. The Species at Risk Public Registry is the main source for the most current official information. If there is any difference between this dataset and a recovery document, the recovery strategy or action plan is the authoritative source.Some habitat locations are considered sensitive. For these species, the data may be shown in a less detailed way, or at a broader geographic scale, to avoid increasing risks to the species. For more detailed information on critical habitat, contact the Canadian Wildlife Service at scf-geocarto-cws-geomapping@ec.gc.ca.The data is current as of the date of modification.

Index Site Surveys Data for Olympia Oysters, Ostrea lurida, in British Columbia – 2009 to 2023
The Olympia oyster (Ostrea lurida Carpenter, 1864) is one of four species of oysters established in British Columbia (BC), Canada, and the only naturally occurring oyster in BC (Bourne 1997; Gillespie 1999, 2009). O. lurida reaches the northern limit of its range in the Central Coast of British Columbia at Gale Passage, Campbell Island, approximately 52°12’N, 128°24’W (Gillespie 2009).First Nations historically utilized Olympia oysters for food and their shells for ornamentation (Ellis and Swan 1981; Harbo 1997). European settlers harvested Olympia oysters commercially from the early 1800s until the early 1930s when stocks became depleted and the industry moved towards other larger, introduced oyster species (Bourne 1997; Quayle 1988). Since that time, Olympia oysters have likely maintained stable populations in BC, but have not recovered to abundance levels observed prior to the late 1800s (Gillespie 1999, 2009).Olympia oysters were designated a species of Special Concern by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in 2000 and 2010 and listed under the Species at Risk Act (SARA) in 2003 (DFO 2009; COSEWIC 2011). A management plan was developed and posted to the SARA Public Registry in 2009 (DFO 2009). One of the objectives of this plan was to ensure maintenance of the relative abundance (density) of Olympia oyster at index sites. The plan also recommended development of a survey protocol for determining relative abundance (density) estimates. In response, a Canadian Science Advisory Secretariat (CSAS) Research Document was completed recommending a survey method for Olympia oysters (Norgard et al. 2010); a CSAS Science Advisory Report (DFO 2010) for selection of index sites was also completed.Thirteen index sites were chosen from a mixture of previously surveyed sites, and by random site selection. In 2014, a fourteenth site was added at Joes Bay in the Broken Group area in partnership with Parks Canada. The selected sites provided a representative sample of Olympia oyster populations in different geographic zones in the Pacific region and span the much of the range of Olympia oysters in BC. The number of sites was reduced to six in 2018 so that annual surveys could be completed to better understand population dynamics and identify long-term trends.
Critical habitat of the St. Lawrence estuary population of Striped Bass
Striped Bass critical habitat (St. Lawrence estuary population) defined by the analysis of available knowledge in 2011 and a scientific advice.PurposeThe status of the Striped Bass population of the St. Lawrence Estuary is in constant evolution. It went from indigenous population until the end of 1960 to designated extirpated in Canada under the Species at Risk Act (SARA) in 2011.Still in 2011, the status of the population of the St. Lawrence Estuary was reassessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) following the Ministère des Ressources naturelles et de la Faune du Québec re-introduction efforts and was designated endangered (COSEWIC 2012). Under SARA, critical habitat must be designated for all threatened, endangered or extirpated species.Additional InformationThe analysis of available knowledge on habitat quality assessment and its use by the Striped Bass was realized using two research documents: Pelletier et al. (2010) and Robitaille (2010). These documents were then reviewed during a scientific peer review meeting in April 2010. A Recovery Strategy was also established in 2011.Pelletier, A.-M., G.

Rocky Mountain Ridged Mussel Density Survey Data
Rocky Mountain Ridged Mussels (Gonidea angulata) are listed under the Species at Risk Act (SARA) as a species of special concern and have been re-assessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as endangered. These fresh water mussels are only found in Canada in the Okanagan Valley of British Columbia. As a continuation of previous work and to inform future assessments and conservation efforts within this geographic range, seven easily accessible sites known to have high densities of G. angulata were selected as prospective index sites to monitor relative abundance (i.e. mussel bed density) using snorkel surveys. For lake sites, a two-stage sampling design was conducted using transects and quadrats. For the river site, cumulative counts from sides of the river were collected. Some sites were sampled only once while others were sampled multiple times from 2011-2016. Mean mussel densities across all surveys ranged from 0.19 to 2.86 mussels/m2, corresponding to site abundance estimates ranging from 102 to 3,276 mussels. Depth measurements were also taken at most sites to inform the Fish Water Management Tool of the Okanagan Water Management Board.
