The National Red List Project

Please note, this National Red List website contains a subset of data whilst we transition to national focal point driven data uploads. We thank you for your patience with this and welcome national contributors to get in touch to update their national dataset. Terms of Use including citation guidance are found here.

Assessment rationale/justification
Population size is low and has declined by 7% over the past four years (population size in 2001 was 201 killer whales of all ages). Northern residents are subject to high levels of human interaction (boat traffic) and may be vulnerable to declines in the abundance of salmon and the effects of contaminants on reproduction and survival.; La taille de la population est faible et a connu un déclin de 7 p. 100 au cours des quatre dernières années (la taille de la population en 2001 était de 201 épaulards de tous les à¢ges). Les résidents du Nord sont sujets à un niveau élevé d'interaction humaine (circulation de bateaux) et peuvent être vulnérables aux déclins du nombre de saumons et aux incidences des contaminants sur la reproduction et la survie.
