5. Review of Recovery activities

5.1. Recovery Objectives

This review considers recovery activities to address each recovery objective outlined in the North Atlantic right whale Recovery Strategy (DFO 2014). The Recovery Strategy describes seven objectives to achieve recovery:

  1. Reduce mortality and injury as a result of vessel strikes;
  2. Reduce mortality and injury as a result of fishing-gear interactions (entanglement and entrapment);
  3. Reduce injury and disturbance as a result of vessel presence or exposure to contaminants and other forms of habitat degradation;
  4. Monitor population and threats;
  5. Increase understanding of life history characteristics, low reproductive rate, habitat, and threats to recovery through research;
  6. Support and promote collaboration for recovery between government agencies, academia, environmental non-government groups, Aboriginal groups, coastal communities, and international agencies and bodies; and,
  7. Develop and implement education and stewardship activities that promote recovery.

Objectives 1-3 directly address reducing identified threats to North Atlantic right whales. Objectives 4-7 describe research and monitoring approaches that could further contribute to addressing threats, but only indirectly. As this review is focused on assessing effectiveness of recovery activities that directly reduce threats to North Atlantic right whales, only measures listed under Objectives 1-3 are evaluated (Section 6), while other relevant measures listed under Objectives 4-7 are considered separately (Section 7).

5.2. Threats

To review the effectiveness of recovery activities towards achieving the interim recovery goal, the efficacy of the measures towards reducing threats to the population was considered. The Recovery Strategy identifies three major threats to North Atlantic right whales: vessel strikes, fishing-gear entanglement, and disturbance and habitat degradation. The latter is further divided into four threats: contaminants, acoustic disturbance, vessel-presence disturbance, and changes in food supply (DFO 2014). Recovery activities to address these threats are considered in this review.

5.3. Review of Recovery activities

To address identified threats to North Atlantic right whales, several conservation initiatives and recovery activities have been implemented throughout Canada and the USA, and are presented in Table 1 and discussed in more detail in Section 6. In some cases, recovery activities implemented prior to 2005 are also discussed as they highlight important accomplishments or recovery activities that were unsuccessful in reducing threats.

Table 1. Recovery activities since 2005 that have been or are currently being implemented within Canada (the main focus of this review) and in some cases the USA and internationally (in italics) to address North Atlantic right whale recovery objectives. The broad strategies presented were obtained from the Recovery Strategy (DFO 2014). “Threat(s) Addressed” lists the relevant threats for each recovery activity; “indirectly” indicates that the listed threats are only indirectly addressed by the recovery activity. “Status” refers to the progress towards completion of each recovery activity, assigned as”Not yet initiated” (recovery activity has not yet begun). “Partially Completed” (some work has been done but further work is required), “Completed” (no further work is required), “Ongoing” (if the work is underway and continuous), or “Unknown” (at the time of this review there was no information available to assess the status of the recovery activities). The majority of the achievements are listed in the Progress Report (DFO 2016b). Note that several of the recovery activities could be listed under multiple objectives, but to reduce repetition are only listed once under the objective to which they are likely most relevant.

  • The North Atlantic right whale Fisheries Mitigation Working Group has developed and distributed questionnaires to gather information on the type of gear used in North Atlantic right whale habitat and migratory pathways

Objective 7: Develop and implement education and stewardship activities that promote recovery in Canada

Continue to expand, refine, and update programs to educate mariners about the problems facing North Atlantic right whales, available shore-based resources, and how changes to vessel operations will help address those problems.

Develop and provide a cetacean identification training program

All threats (indirectly)

Ongoing

  • DFO Maritimes region developed a cetacean identification training program and delivered training to commercial fishery observers, C&P Officers, Defense Research and Development Canada researchers and Canadian Wildlife Service (CWS) bird observers
  • DFO Newfoundland and Labrador region also offers a similar program for marine mammal observers aboard seismic vessels when requested
  • MARS offered cetacean training, as well as live and dead cetacean response training across the Maritimes
  • World Wildlife Fund provided live and dead cetacean identification training to at-sea observers in Nova Scotia and Newfoundland

Develop programs to educate the general public about North Atlantic right whale conservation strategies and stewardship actions

Develop a Marine Species Identification Guide Common to the Bay of Fundy and Scotia Shelf Region

All threats (indirectly)

Completed

  • DFO developed a marine animal identification key that was distributed to fishing industry, whale watching companies, C&P Officers, the Canadian Coast Guard, fisheries observers, and marine mammal observers (DFO 2013)

Develop programs to educate the general public about North Atlantic right whale conservation strategies and stewardship actions - continued

Develop websites with information about North Atlantic right whales

All threats (indirectly)

Ongoing

  • There are several websites that contain information on North Atlantic right whales including but not limited to:
  • DFO has websites about species at risk including North Atlantic right whales
  • The Canadian Whale Institute has a website that describes research and recovery efforts in Canada
  • The GMWSRS website has general information about North Atlantic right whales and whales observed in the Bay of Fundy each year
  • The MARS website includes information to help identify marine mammals
  • The North Atlantic Right Whale Consortium website has a North Atlantic right whale information page
  • NOAA's interactive North Atlantic right whale sightings map
  • The New England Aquarium has a blog for communicating updates of their research activities including field work in Canadian waters

Provide information on North Atlantic right whales and participate in outreach events

All threats (indirectly)

Ongoing

  • DFO Newfoundland and Labrador has a public outreach programme to collect sightings and distribute information about species at risk
  • DFO presents information on North Atlantic right whales to the public and participates in annual Oceans Day Events
  • GMWSRS hosted public lectures for tourists and produced "Right whale Stewards" booklet to middle schools and have also made presentations to university and high school students, whale camp groups, sea cadets, and student science fairs

Expand and refine collaboration efforts with fishing industry that promote best practices to reduce the number and severity of whale/fishing gear interactions

Review gear configuration to determine methods for minimising entanglement risk

Fishing-gear entanglements (indirectly)

Ongoing

  • DFO Newfoundland and Labrador has contract the Fish, Food, and Allied Workers Union (FFAW-Unifor) to review the development of trap mooring ropes with the goal of minimising entanglement risks for leatherback sea turtles and large whales

Promote a public reporting system for dead, stranded, injured, entangled, or entrapped right whales as part of the existing whale disentanglement program

Promote 24-hour hotlines

Vessel strikes and fishing-gear entanglements (indirectly)

Ongoing

  • In Atlantic Canada and in Québec, several regional response networks, including the Marine Mammal Emergency Response Network, and MARS provide widely-advertised 24-hour hotlines
