X = Usual range of species not in NWT. b Describes reasons for a change in status rank between 2006 and 2011. : Increasing Risk, : Decreasing Risk, ∃: Error correction, #: Species new to the NWT, T: Taxonomic change, : Information added, Π: New rank category, A: Changed due to detailed assessment by COSEWIC since 2006. See Data Sources and Methods for more details. c For your convenience, the status derived from other processes than the one presented in this report is described in this column. COSEWIC Status: Status for a species in Canada if it has already been assessed in a detailed manner by COSEWIC as of 2010. The year of each assessment is given with each status. After 2010, please consult current and additional status assessments on the COSEWIC web page (www.cosewic.gc.ca). Global Conservation Concern: Rank of a species in the world as assessed by NatureServe. GH: Possibly Extinct, G1: Critically Imperilled, G2: Imperilled, G3: Vulnerable.
