Action plan for the northern and southern resident killer whale (Orcinus orca) in Canada / [prepared by Sheila J. Thornton].: CW69-21/27-2016E-PDF

"The Northern and Southern Resident Killer Whale (Orcinus orca) were listed as Threatened and Endangered, respectively, under the Species at Risk Act (SARA) in 2003. This Action Plan is considered one in a series of documents that are linked and should be taken into consideration together, including the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) status report, a recovery potential assessment, and the Recovery Strategy. Principal among the anthropogenic threats to recovery are reductions in the availability or quality of prey, environmental contamination, and both physical and acoustic disturbance. As these threats are common to all three ecotypes, the measures identified in the Resident Killer Whale Action Plan are highly likely to benefit Transient (Bigg’s) and Offshore Killer Whale populations that frequent Canadian Pacific waters. This Action Plan outlines measures that provide the best chance of achieving the population and distribution objectives for the species, including the measures to be taken to address the threats and monitor the recovery of the species. The recovery strategy defined the population and distribution objective for the Northern and Southern Resident Killer Whale as: Ensure the long-term viability of Resident Killer Whale populations by achieving and maintaining demographic conditions that preserve their reproductive potential, genetic variation, and cultural continuity"--Executive summary, p. iii.
