Proposed Expansion of Killer Whale “Critical Habitat”

Recent amendments to the Recovery Strategy for the Northern and Southern Resident Killer Whales (Orcinus orca) in Canada 2018 (proposed)  expand the area to be included as critical habitat. Under the recovery strategy action plan, this area will be subject to measures that respond to perceived threats to killer whale survival. The threat of “Reduced prey availability” identifies “Fishing for Chinook Salmon, Chum Salmon, and other important prey species” and “Other activities that are detrimental to habitat and survival of prey (e.g. fishing for forage fish species)” as activities likely to result in the destruction of critical habitat. The images here are from the above linked document, and show the areas proposed.
