6. Ranked Species Lists – What are the details? The general status ranking process results in lists of species with general status ranks. These are detailed in the following pages. Common Names and Scientific Species Names Each species is listed using the accepted standard nomenclature for each group. Synonyms, old names, and local names can be found in the NWT Species Monitoring Infobase on www.nwtspeciesatrisk.ca. For some species groups, common names were not available. Common names were developed for this report with the help of experts in each species group, based on the scientific names and the species’ ecology and distribution. General Status Ranks Each species is given a general status rank according to the process described in this report. For some species with very high cultural and economic importance, (e.g., caribou, inconnu, Arctic char) we also provide a rank for each subspecies, population, stock, or ecotype present in the NWT. Range Notes All species marked by an “L” have a limited distribution in the NWT as many are at their limit or edge of their natural range. Species marked by an “X” are outside their usual range in the NWT. Extra information on habitat requirements is also provided for fish. Reasons for Change Reasons for changing the rank of a species between 2006 and 2011 are noted in the following pages using the codes described in Data Sources and Methods. Detailed Assessments in Canada and the NWT One of the main objectives of the General Status Ranking Program is to provide a prioritized list of species that “May Be At Risk” and may need to be assessed in a more detailed manner. The Committee on the Status of Endangered Species in Canada (COSEWIC) performs this detailed assessment for species in Canada. For your convenience, each table provides the COSEWIC status for all species (subspecies or populations) that occur in the NWT and have already been assessed in a detailed manner by COSEWIC as of 2010. Please consult current and additional status assessments on the COSEWIC web page. Link to www.cosewic.gc.ca. In Canada, species can be legally listed under the Species at Risk Act (SARA). Legal listing is based on the detailed assessments performed by COSEWIC. NWT species listed in Canada under SARA are not noted in this report; please refer to the official SARA registry for more information. Link to www.sararegistry.gc.ca. In the NWT, the Species at Risk Committee (SARC) is tasked under the Species At Risk (NWT) Act to assess species in more detail. As of 2010, no species has been listed under this Act. In future reports, for your convenience, we will add a note on species assessed by SARC. For more information on SARC Link to www.nwtspeciesatrisk.ca. Status Ranking at the Global Level Species that are in danger of extirpation in the NWT may be quite common in the rest of the world. On the other hand, species that are under threats in other countries may be secure in the NWT. For your convenience, each table provides the Global Rank for species of Global Conservation Concern (G1 - G3) according to NatureServe as of 2010. Please consult current and additional Global Ranks on the NatureServe web page. Link to www.natureserve.org. General Status Ranks of Wild Species in the Northwest Territories 17
