The federal, provincial, and territorial government signatories under the Accord for the Protection of Species at Risk (1996) agreed to establish complementary legislation and programs that provide for effective protection of species at risk throughout Canada. Section 46 of SARA requires the competent minister to report on the implementation of the recovery strategy for a species at risk, and on the progress towards meeting its objectives within five years of the date when the recovery strategy was placed on the Species at Risk Public Registry, and in every subsequent five-year period, until its objectives have been achieved or the species’ recovery is no longer feasible.
Reporting on the progress of recovery strategy implementation requires reporting on the collective efforts of the competent minister, provincial and territorial governments, and all other parties involved in conducting activities that contribute towards the species’ recovery.Recovery strategies identify broad strategies and approaches that will provide the best chance of recovering species at risk. Some of the identified strategies and approaches are sequential to the progress or completion of others and not all may be undertaken or show significant progress during the timeframe of a Report on the Progress of Recovery Strategy Implementation (Progress Report).
The Minister of Fisheries and Oceans is the competent minister under SARA for the Northern Bottlenose Whale, Scotian Shelf Population and has prepared this Progress Report.
As stated in the preamble to SARA, success in the recovery of species at risk depends on the commitment and cooperation of many different groups that will be involved in implementing the directions set out in the recovery strategy and will not be achieved by Fisheries and Oceans Canada, or any other jurisdiction, alone. The cost of conserving species at risk is shared amongst these groups. All Canadians are invited to join in supporting and implementing the Recovery Strategy for the Northern Bottlenose Whale,Scotian Shelf population for the benefit of the species and Canadian society as a whole.
This Progress Report was prepared by Katherine Hastings (Species at Risk Management Division, Fisheries and Oceans Canada (DFO), Maritimes Region), with input from other DFO sectors, federal government departments, regulators, Aboriginal organizations, non-government organizations, and academic partners. DFO would like to express its appreciation to all individuals and organizations who have contributed to the recovery of the Northern Bottlenose Whale, Scotian Shelf Population.
The Northern Bottlenose Whale, Scotian Shelf population (NBW-SSP) was listed as Endangered under the federal Species at Risk Act in 2006. Threats to this species include acoustic disturbance, oil and gas activities, entanglement in fishing gear, contaminants, changes to food supply, and vessel strikes. A Recovery Strategy for this population was published as final on the Species at Risk Public Registry in May 2010.
Four recovery objectives were included in the Recovery Strategy for the NBW-SSP. This report outlines activities undertaken since May 2010 in support of these recovery objectives. Fisheries and Oceans Canada (DFO) is the authority responsible for the recovery of the NBW-SSP, and has been working to advance the implementation of the Recovery Strategy in several ways. These efforts continue to be strongly supported and complemented by those of the academic community, non-government organizations, Aboriginal organizations, and stakeholders.
Measureable progress has been made toward achieving each of the four recovery objectives, which broadly aim to improve understanding of (1) Northern Bottlenose Whale ecology, (2) population size, trend, and distribution, and (3) anthropogenic threats, while also (4) enhancing the awareness and engagement of stakeholders and the public. Significant progress was made toward addressing Recovery Objectives 2 and 4, in particular. For example, photos collected during dedicated visual surveys were used to build up the Northern Bottlenose Whale photo-identification database. This database facilitated the calculation of the most precise population estimate to date in 2013. Many activities were undertaken to address Recovery Objective 4, including efforts to engage ocean users directly, as well as raise awareness of the species and its threats among the public. Large-scale poster campaigns, public lectures, information booths, and social media are just a few examples of how audiences were reached.
The majority of the 16 performance indicators identified in the Recovery Strategy were either partially met or met. Areas where further work is required include: quantifying rates and sources of NBW-SSP mortality and injury; assessing and monitoring the threat of entanglement; measuring ecosystem contaminant levels; evaluating prey composition; delineating population range boundaries; and assessing habitat use outside of known critical habitat areas. The performance indicators that were met during the first five years of recovery strategy implementation will require continued attention over the next five years to maintain progress.
This Progress Report describes the progress made toward meeting the objectives listed in the “Recovery Strategy for the Northern Bottlenose Whale (Hyperoodon ampullatus), Scotian Shelf population, in Atlantic Canadian Waters” for the five-year period since it was published in May 2010. This report is one in a series of documents for this species that are linked and should be taken into consideration together, including the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) status report (COSEWIC 2011), recovery potential assessments (DFO 2007; 2011), a recovery strategy (DFO 2010a; 2016a), and an action plan (DFO 2016b). The protection and management of the Gully Marine Protected Area (MPA), designated in 2004 under the Oceans Act, continues to play an important role in the recovery of the NWB-SSP. More information on the Gully MPA can be found in the management plan (DFO 2008; 2015c) and the 10-year progress report (DFO 2014e).
Section 2 of this report reproduces the COSEWIC assessment summary and recaps the threats to individual Northern Bottlenose Whales and their critical habitat. Also reproduced in Section 2 are the recovery goal, recovery objectives, and performance indicators from the Recovery Strategy. During the reporting period (May 2010-May 2015), many activities were undertaken in support of the recovery objectives. These activities, along with an assessment of recovery progress according to the performance indicators, are presented in Section 3. Section 4 provides a concluding statement about the implementation of the Recovery Strategy during the reporting period, as well as suggestions on areas of focus to guide future recovery efforts.
2.1 COSEWIC assessment summary2
Assessment summary – November 2002
Common name: Northern Bottlenose Whale (Scotian Shelf population)
Scientific name: Hyperoodon ampullatus
Reason for designation: This population totals about 130 individuals and appears to be currently stable. Oil and gas development in and around the prime habitat of this population poses the greatest threat and will likely reduce the quality of their habitat. However, there is little information as to how this species is, or is not, affected by oil and gas development activities.
Occurrence: Atlantic Ocean
Status history: The Northern Bottlenose Whale was given a single designation of Not at Risk in April 1993. Split into two populations in April 1996 to allow a separate designation of the Northern Bottlenose Whale (Scotian Shelf population). Scotian Shelf population designated Special Concern in April 1996. Status re-examined and uplisted to Endangered in November 2002. Last assessment was based on an existing status report with an addendum.
2.2.1. Threats to the species at risk
Threats to the Northern Bottlenose Whale, Scotian Shelf populationhave been identified in the relevant COSEWIC assessment reports (COSEWIC 2002; 2011) and Recovery Potential Assessments (DFO 2007; 2011). Threats of current concern are summarized in Table 1.
Table 1: Table 1 includes a brief description of each threat identified in the Recovery Strategy for the Northern Bottlenose Whale (Scotian Shelf population). There are two columns and seven rows in the table, including the header row. The header row, from left to right, includes the column headers “Threat” and “Description”. In the Threat column there are six threats, which include entanglement in fishing gear; oil and gas activities; acoustic disturbance; contaminants; changes to food supply; and vessel strikes. In the Description column, a 1-2 sentence description of each threat is provided. End of Table 1.
|Entanglement in fishing gear||There have been nine documented cases of Northern Bottlenose Whale (NBW) entanglement in trawl or longline fishing gear in Atlantic Canada over the past 35 years. Evidence of past entanglement has also been observed in scarring patterns on individual whales.|
|Oil and gas activities||Offshore oil and gas development has occurred on the Eastern Scotian Shelf since 1992, and is projected to increase in coming years. Exploration and production activities have the potential to affect the NBW-SSP through acoustic disturbance (e.g. seismic surveys, drilling), accidental oil spills, and increased vessel traffic.|
|Acoustic disturbance||The NBW relies on sound to communicate, forage, and navigate. The introduction of anthropogenic noise into the marine environment can interfere with their ability to carry out these functions, and may lead to temporary or permanent hearing loss, displacement, behavioural changes, physical injury, stranding, and mortality.|
|Contaminants||Marine pollutants, including floating debris and chemical contaminants, have been known to have adverse effects on marine mammal health through ingestion, bioaccumulation, or entanglement. Little is known about the impact of pollution on the NBW-SSP, specifically. Sources of pollution include fishing (e.g. discarded or lost gear, plastics), commercial shipping (e.g. loss of cargo, accidental discharges), oil and gas activities, munitions dumpsites, and terrestrial run-off.|
|Changes to food supply||The preferred prey species of the NBW-SSP is squid of the genus Gonatus. The abundance of Gonatus squid is thought to be especially high in the submarine canyons where the NBW-SSP is concentrated. Disruption or diminishment of this food supply could pose a threat to the NBW-SPP.|
|Vessel strikes||Whales can be seriously or mortally injured by a collision with a vessel. To date, there have been no confirmed instances of an NBW being struck by a vessel on the Scotian Shelf; however, scarring patterns on certain individuals have been attributed to possible interactions with vessels.|
2.2.2 Threats to critical habitat
Critical habitat is identified for the NBW-SSP in the Recovery Strategy (DFO 2010a; 2016a), and includes the Gully, Shortland, and Haldimand submarine canyons, located at the edge of the eastern Scotian Shelf. Activities that could result in the destruction of critical habitat are also outlined in the Recovery Strategy, and are summarized in Table 2.
Table 2: Table 2 provides an overview of the threats to the critical habitat identified for the Northern Bottlenose Whale (Scotian Shelf population). There are three columns and five rows in the table, including the header row. The header row, from left to right, includes the column headers “Threat”, “Activities”, and “Effect-Pathway”. In the Threat column there are four threats, which include acoustic disturbance; changes to food supply; contaminants; and alteration of biological and physical oceanographic conditions. In the Activities column, examples of activities likely to destroy critical habitat are listed. In the Effect-Pathway column, the ways in which each identified threat or activity may destroy critical habitat are described. End of Table 2.
|Acoustic disturbance||Seismic surveys|
In-water or land-based industrial activities (such as pile driving, dredging and construction)
Underwater noise production causing:
|Changes to food supply||Capture and removal of prey species (e.g. a fishery, bycatch)|
Reduction in the abundance and availability of prey (such as Gonatus squid) causing:
|Contaminants||Dumping and discharges of contaminants / pollution (e.g. ocean dumping, industrial developments and persistent vessel discharges, oil and gas production)|
Release of pollutants (such as marine debris or chemical pollutants) into the marine environment causing:
|Alteration of biological and physical oceanographic conditions||Large-scale industrial development (e.g. offshore mining, dumping of aggregates, renewable energy development and generation)|
Modifications to the seabed causing:
A final Recovery Strategy for the NBW-SSP was included in the Species at Risk Public Registry in May 2010 (DFO 2010a), and was recently amended to include a more detailed description of existing critical habitat (DFO 2015a). Recovery of this population was deemed to be both biologically and technically feasible. The overall recovery goal, as stated in the recovery strategy, is “to achieve a stable or increasing population and to maintain, at a minimum, current distribution”. Four recovery objectives, outlined in Table 3, were developed to support the achievement of the overall recovery goal. To facilitate the evaluation of progress toward the recovery of the NBW-SSP, measurable performance indicators were included in the Recovery Strategy (DFO 2010a). These performance indicators are reproduced in Table 3.
The overall recovery goal and objectives in the Recovery Strategy remain relevant. The technical feasibility of some of the recovery objectives is challenged by the remote offshore distribution of this species. However, this reality has not prevented progress. Funding has already been secured for continued NBW research on the Scotian Shelf over the next five years. This research is expected to address several of the recovery objectives and corresponding strategies.
Table 3: Table 3 provides the four recovery objectives and associated performance indicators as put forward in the Northern Bottlenose Whale (Scotian Shelf population) Recovery Strategy. There are two columns and five rows in the table, including the header row. The header row, from left to right, includes the column headers “Recovery objective” and “Performance indicator”. In the Recovery Objective column each of the four recovery objectives are described. Briefly, these objectives correspond to 1) improving understanding of Northern Bottlenose Whale biology and ecology; 2) improving understanding of Northern Bottlenose Whale population size and distribution; 3) improving understanding of threats to Northern Bottlenose Whales; and 4) engaging stakeholders in recovery efforts. In the Performance Indicator column, 3-5 performance indicators are listed for each recovery objective. End of Table 3.
|Recovery Objective||Performance Indicator|
Improve understanding of NBW ecology, including critical habitat requirements, carrying capacity, breeding, trophic interactions, links with other populations (e.g. Davis Strait), and sources of mortality.
Improve understanding of the population size, trend and distribution.
Improve understanding of and monitor anthropogenic threats, including fishing gear interactions, petroleum development, noise, and contaminants, and develop management measures to reduce threats where necessary.
Engage stakeholders and the public in recovery action through education and stewardship.
3. Progress towards recovery
3.1 Recovery activities
Table 4 outlines recovery activities that have been initiated or completed during the five years since the Recovery Strategy was published as Final in 2010. These activities are organized under three broad headings: (1) research and monitoring; (2) management; and (3) engagement, education, and outreach. The particular recovery objective(s) and performance indicator(s) related to each activity are also listed. The activities that occurred during the reporting period (May 2010-May 2015) contributed to meeting all four recovery objectives. The extent to which each of the performance indicators were met during the first five years of recovery strategy implementation is discussed in Section 3.3. Many of the activities listed in Table 4 were undertaken specifically to advance the recovery of the NBW-SSP. Others were undertaken for different or broader purposes but still resulted in benefits to the population (e.g. Gully MPA management activities, broader marine mammal conservation initiatives).
Table 4: Table 4 outlines the activities undertaken in support of Northern Bottlenose Whale (Scotian Shelf population) recovery during the period May 2010 to May 2015. The table contains five columns and many rows that span several pages. From left to right, the column headers are as follows: Recovery activity; Description and results; Recovery objective; Performance indicator; and Participants. Each row describes a particular activity and links it to one or more of the recovery objectives and performance indicators outlined in Table 3. A list of the participants in each activity is also provided. End of Table 4.

|Population analysis, including size, trend, and sex ratio||Digital photographs of individuals from the NBW-SSP were collected during the summers of 2010 and 2011 for identification purposes. Analysis of the photographs using mark-recapture techniques rendered an updated estimate of population size (143 animals, with a 95% confidence interval of 129-156 animals). This is considered the most precise NBW population estimate obtained to date, with a margin of error less than +/-10%. The population trend (1988-2011) was also assessed, and the results suggest the population is currently stable. Changes in sex-ratio over time (1988-2011) were evaluated statistically and the demographics of the population were found to be unchanged.|

|Analysis of social structure and organization within the NBW-SSP||Using digital photographs and video collected since 1988, the social behaviours of NBW on the Scotian Shelf were examined. Areas of study included the strength and variability of associations among individuals over different time scales and breathing synchrony. Such studies contribute to establishing baseline knowledge of natural behaviours, which is needed to monitor the effects of human activities on the whales. |

|Collection of biopsy samples||Six biopsy samples were collected from six different NBW during field work in the Gully in 2013. These biopsy samples have been stored for future analysis, which may include hormone analyses to determine nutritional stress or reproductive status in females. Lipid content may also be analyzed. The 2013 field work presented a valuable opportunity to test the effectiveness of biopsy sampling methodologies on NBW. |

|Deployment of accelerometer tags||Five different NBW were tagged with data loggers during Gully field studies in 2011 and 2013. These tags record information such as depth, heading, acceleration, and water temperature that is used to learn about diving behaviour. The tag data retrieved in 2011 was the second set of dive records ever to be collected for this species. In 2013, one Digital Acoustic Recording Tag (D-TAG) was deployed, which also recorded whale vocalizations. Both tagging studies resulted in important lessons learned regarding tagging technique and tag placement on NBW.|

|Maintenance of NBW-SPP sightings and incidents records||DFO Maritimes and NL Regions maintain Cetacean Sightings Databases that include live sightings records obtained from multiple sources, such as research scientists, marine mammal observers, at-sea fisheries observers, and the Canadian Coast Guard. All stranding, entanglement, injury, and mortality events are recorded and maintained by regional marine mammal response networks. Data is collected and incorporated into these databases on an ongoing basis.|

|Collection and maintenance of digital multimedia data (e.g. photos, videos, audio)||All of the NBW-SSP photographs, video, and acoustic recordings taken since 1988 have been collected, centralized, and digitized to facilitate future research, analyses, and monitoring. New data is being added on an ongoing basis. NBW-SSP sightings and incident data will be integrated into this collection in the future. |

|Development of NBW digital photo-identification catalogue||All NBW film photographs have been digitized, and both the digitized and more recent digital photographs and associated metadata have been organized into a photo-ID catalogue to facilitate analysis. These photographs have been collected by research scientists and at-sea observers. DFO has supplied digital cameras and identification training to at-sea observers in NL Region.||2||6, 7, 8, 9, 11||DFO|
|Characterization of NBW vocalizations||Using acoustic recordings collected from the Gully, NBW echolocation pulses (clicks) were analyzed and their characteristics described. NBW pulse reflections were also described for the first time. These results are being used to refine the automated click detectors often applied to raw acoustic data. This will help increase the accuracy of detections. |

|Review of mitigation and monitoring measures for seismic survey activities in and near the habitat of cetacean species at risk||On March 25-27, 2014, a DFO science advisory process was held on the topic of seismic noise and its impact on at-risk whale species. The purpose of this process was to (a) identify sound exposure criteria, (b) identify whether the current “Statement of Canadian Practice with respect to the Mitigation of Seismic Sound in the Marine Environment” (SOCP) is adequate for avoiding harm to whales and their critical habitat, and (c) to identify additional mitigation and monitoring measures if necessary. The NBW-SSP was used as a case study in this process. The advice generated through this process will be used by DFO in regulating and managing relevant activities.|

|Monitoring for presence of NBW-SSP outside of Eastern Scotian Shelf canyons||In 2013 and 2014, aerial cetacean surveys were conducted off Newfoundland and Labrador (NL), including areas off southern Newfoundland where the NBW-SSP may occur. In addition, several underwater acoustic recorders were deployed. The acoustic data collected will be examined to determine if it can be used to document the presence of this species in these areas throughout the year. Similarly, an underwater acoustic recorder was deployed in Logan Canyon (west of the Gully) in June through September 2014. The recordings are being analyzed for NBW clicks. Between May and September 2015, several acoustic recorders were deployed at deep-water locations along the shelf break and slope, from Nova Scotia to NL, where NBW may be observed. These recorders will be at these locations for 1-2 years.|
Sightings data from cetacean surveys, and collected opportunistically during other activities, have also helped to build an understanding of the NBW-SSP’s presence outside of the Eastern Scotian Shelf canyons. These data are obtained from various sources, including aerial cetacean abundance surveys conducted over Canadian waters by the US National Oceanic and Atmospheric Administration (NOAA), as well as from Canadian Wildlife Service seabird observers, marine mammal observers, fisheries officers, and others.
|Scientific evaluation of Gully MPA monitoring needs and available data||Two regional DFO science advisory processes (2010 and 2012) have informed the development of a draft Gully MPA monitoring plan. Many indicators, monitoring protocols, and methodologies were considered during the advisory processes. The resulting science advice proposed 47 indicators to track and assess progress toward meeting the MPA’s conservation objectives. Several of the indicators are related specifically to NBW-SSP, while others are related to their threats or habitat.|

|Processing and analysis of mesopelagic and bathypelagic survey samples and data||Four mid-water trawl surveys were carried out in the Gully between 2007 and 2010. The surveys primarily targeted organisms that feed on phytoplankton and zooplankton. The survey samples were expected to include the prey of Gonatus squid, which are in turn the prey of NBW. Laboratory work and data analyses are currently ongoing, and are expected to reveal new information about food web dynamics and energy flow in the Gully canyon ecosystems. Learning more about these lower prey layers is helping to build understanding of the ecology of NBW and threats to the Scotian Shelf population. In addition, a small number of Gonatus squid were caught during the same surveys, and samples were taken for stomach-content analyses. |

|Analysis of offshore vessel traffic patterns||Using Long Range Identification and Tracking (LRIT) data, a retrospective analysis of offshore vessel traffic in Atlantic Canada was completed for the period February 2010-February 2011. This study indicated that vessel traffic density is moderate to high in and around NBW-SSP habitat relative to other offshore areas in Atlantic Canadian waters. |
A pilot study was also initiated to determine whether satellite-based Automatic Identification System (AIS) data, which is higher resolution than LRIT data, can be used to effectively track and analyze marine traffic within and between the three Eastern Scotian Shelf canyons. Analyses of 2014 AIS data showed that vessel traffic was most dense from July to September, and that cargo vessels were the most common vessel type transiting through the area. Specifically within the Gully MPA boundaries, ~56% of transiting vessels, all carrying foreign flags, travelled at speeds higher than the recommended 10 knots. This analysis has helped to characterize vessel traffic as a possible threat to NBW within the Gully MPA. Similar analyses will be conducted on an ongoing basis to monitor the presence of this threat. A targeted letter campaign is being planned to increase awareness of recommended transit speeds.

|Habitat suitability modeling exercise applied to NBW-SSP||A recent study tested the use of a habitat suitability model as a potential means of predicting NBW-SSP distribution in the Maritimes Region. This model was based on a statistical analysis of the relationship between occurrence data and environmental variables, such as water depth, temperature, seafloor slope, and primary productivity. The results of the study suggested that with further refinement, this method could be effectively used to identify important habitat areas and improve our understanding of habitat use and distribution. An augmented version of this approach was also initiated in the NL Region to produce a comparative habitat use model. |

|Species status reassessment by COSEWIC||In 2011, COSEWIC reassessed the status of NBW in Canadian waters based on the best available scientific information and found no change in the status of the Scotian Shelf population. For the first time, a geographic boundary was used to delineate the two known genetically distinct populations (also known as designatable units or DUs) in Canada. The status report acknowledged the uncertainty regarding the boundary between the DUs. Specifically, it is unclear to which DU animals sighted in the easternmost range of the Scotian Shelf DU, and the southernmost range of the Baffin Bay-Davis Strait-Labrador Sea DU, truly belong. Additional scientific study is needed to better understand the distribution of these two populations. |

This work, to occur over a five-year period, will include photo-identifications, scarring analysis, biopsy collection and analysis, and vocalization descriptions. It will help to increase knowledge of population dynamics, genetics, contaminant loads, diet, threats, and communication.

|Activity plan approval process under the Gully MPA Regulations||Over the five-year reporting period, 21 activity approvals were issued for the Gully MPA. All proposed activities within the MPA follow the approval process as described in Sections 5 and 6 of the Gully Marine Protected Area Regulations. This includes an assessment of potential environmental or cumulative impacts, and the consideration of appropriate mitigation measures to minimize disturbance to NBW. Activities within Zones 1 and 2 must have a scientific research or monitoring component. |

|Identification of the “Eastern Scotian Shelf Canyons” as an Ecologically and Biologically Significant Area (EBSA)||The “Eastern Scotian Shelf Canyons”, which encompasses the NBW-SSP critical habitat areas, is one of 18 offshore EBSAs identified through a regional peer review science advisory process (February 18-20 and March 24, 2014). EBSAs are areas that warrant a greater-than-usual degree of risk aversion in the management of activities. The identification of EBSAs on the Scotian Shelf will inform regional oceans planning and management, including the design of an MPA network. |

|Oil and gas activities|
|Completion and review of strategic environmental assessments for offshore oil and gas exploration and development activities||During the reporting period, seven strategic environmental assessments (SEAs) were completed for large areas of the Scotian Shelf and Slope. Each SEA evaluated the potential impacts of oil and gas activities on the marine environment, including the NBW-SSP, within a certain geographic area. Public comments on the SEAs were sought and recorded on the CNSOPB Public Registry. DFO reviewed and provided extensive comments on each SEA, which included raising concerns regarding the completeness of the NBW information considered in the SEA and making recommendations regarding potential enhanced mitigation measures for beaked whales. |
SEAs conducted for areas in the NL Region were also reviewed, with consideration given to all species at risk, including the NBW-SSP.

|Completion and review of environmental assessments for seismic programs||During the reporting period, project-specific environmental assessments (EAs) were completed for two seismic exploration programs on the Scotian Shelf and Slope. Both EAs evaluated impacts to the NBW. Public comments on the EAs were sought and recorded on the CNSOPB Public Registry. DFO provided extensive comments, including comments relating to beaked whales. Background was provided on the particular challenges associated with detecting beaked whales and recommendations were made to maximize the probability of detection and enhance threat mitigation. For example, in the 2014 BP Tangier 3D seismic program, the standard observation time prior to airgun ramp-up was increased from the standard 30 minutes to 60 minutes if a beaked whale was detected. This enhanced mitigation measure was made a requirement through the environmental assessment process. A Marine Mammal Monitoring Plan must be approved by CNSOPB as part of the EA process for seismic programs. |
EAs conducted for areas in the NL Region were also reviewed, with consideration given to all species at risk, including the NBW-SSP.

|Ongoing operation of the Marine Mammal Response Program (MMRP)||DFO supports regional marine mammal response networks through the umbrella MMRP. The mandate of the program is to work with partners to track and respond to incidents involving marine mammals, quantify threats, and provide information in support of SARA recovery planning. The funds, expertise, and other resources this program contributes represent an important contingency plan for mobilizing appropriate responses to incidents involving NBW. |

|Ongoing operation of regional marine animal response networks||There are two primary whale response networks operating in Atlantic Canada: the Marine Animal Response Society (MARS), which covers all three Maritime provinces, and Whale Release and Strandings-NL (WRS-NL). Both organizations maintain a widely-advertised, toll-free phone line 24 hours a day, seven days a week. Trained experts are available through these networks to respond directly to reported incidents (e.g. live or dead stranding, entanglement) or provide advice on the most appropriate course of action. MARS and WRS-NL have been in operation since 1990 and 1979, respectively.|
In 2013, a National Stranding Network Steering Committee was formed to oversee the coordination of marine mammal response efforts across the country. The intent of the committee is to maintain and improve the operations of regional networks, foster consistency in response standards across regions, and encourage collaboration and knowledge-sharing.

|Ongoing fisheries compliance monitoring and surveillance in the Gully MPA||Section 4 of the Gully Marine Protected Area Regulations (SOR/2004-112) prohibits all fishing in Zone 1 of the MPA, and restricts fishing in Zones 2 and 3 to certain fixed gear fisheries (i.e. longline directing for halibut, tuna, swordfish, and shark). DFO monitors compliance with this regulation through various means and in cooperation with other departments. Fishing activities in or near the Gully MPA are subject to close surveillance by DFO, and any suspicious activities are investigated. Such cases are rarely observed, and there have been no prosecutions under the Oceans Act. Fisheries compliance monitoring in the Gully MPA is important for minimizing the risk of NBW entanglement.|

|Tourism and whale watching|
|Proposed amendments to the Marine Mammal Regulations for the purpose of reducing disturbance to marine mammals||Marine mammals in Canadian waters are subject to the provisions of the Marine Mammal Regulations (MMRs) under the Fisheries Act. These regulations contain a prohibition against disturbing a marine mammal, except when fishing for marine mammals under the authority of the regulations. Proposed amendments to these regulations were put forward for public consultation in 2012. These amendments elaborate on the concept of disturbance and include enforceable guidelines for viewing marine mammals, such as minimum approach distances. The amendments are not yet in force, but would apply to NBW. The proposed amendments to the MMRs influenced the content of whale watching guidelines for the Gully MPA (see next entry). |

|Development and distribution of whale watching guidelines for the Gully MPA||DFO whale watching guidelines for the Gully MPA were completed in 2013, and continue to be distributed to tour operators. Included are guidelines for approaching and observing whales; leaving whales; observing friendly whales that approach the vessel; and what to do in the event of contact or collision with a whale. These guidelines were developed primarily due to the concentration of NBW-SSP in the area and the interest shown in viewing this species.|

|Monitoring of an individual NBW in Spry Bay, NS||In October 2013, a single NBW was observed in Spry Bay, NS, following a similar sighting in Prospect Bay earlier that week. Such occurrences of live NBWs so near the coast are extremely rare. DFO’s Conservation and Protection Branch was notified and Fishery Officers visited Spry Bay to monitor activities and ensure the whale was not harmed or harassed. MARS and staff from DFO’s Ecosystem Management Branch also visited the site multiple times to monitor the situation. The whale did not appear to be in poor health and was observed feeding. After several days it left the bay and did not return. An attempt was made to photo-ID the individual, but no match was made.||3||13||DFO|
|Ongoing oil pollution prevention and compliance monitoring||Transport Canada’s National Aerial Surveillance Program (NASP) and Environment Canada’s Integrated Satellite Tracking of Pollution (ISTOP) program are used to monitor Canada’s oceans for illegal or accidental oil discharges from vessels. Both programs have contributed to decreasing oil discharges through deterrence and successful prosecutions. The Gully MPA coordinates were provided to the NASP flight planner in 2010, and since then the Gully has been included in aerial patrols whenever feasible. Gully coverage is variable, but averages 1-2 times a week. These patrols contribute to monitoring the threat of oil contamination in NBW-SSP critical habitat. |

Wider distribution within the Maritimes Region is planned for 2015/16.|
MARS and WRS-NL have developed and distributed outreach materials that raise awareness of their respective response networks and what to do if a stranded whale is encountered. For example, in 2011, MARS created an informational brochure, and in 2012, WRS-NL sent stickers with their toll-free number to ocean users in the region.
Awareness campaigns increase the likelihood that trained personnel can respond to NBW incidents, and as a result more can be learned about the species and its threats.

3.2 Activities supporting the identification of critical habitat
Recognizing that other areas of critical habitat may exist, Section 1.9.2 of the Recovery Strategy (DFO 2010a) included a Schedule of Studies (SOS) to support the identification of additional critical habitat. The recently amended Recovery Strategy (DFO 2015a) expands upon the SOS, and progress toward its implementation will be reported following the next five-year reporting period. Table 5 outlines the implementation of the SOS to date. Each study has been assigned one of four statuses:
- Completed: the study has been carried out and concluded
- In progress: the study is underway and has not concluded
- Not started: the study has been planned but has yet to start
- Cancelled: the study will not be started or completed
Table 5: Table 5 summarizes the progress made toward implementing the Schedule of Studies from the Northern Bottlenose Whale (Scotian Shelf population) Recovery Strategy. There are seven columns and two rows in the table, including the header row. From left to right, the column headers are as follows: Study; Timeline; Status; Details; Recovery objective; Performance indicator; and Participants. The single table entry describes the current status of the study included in the 2010 Recovery Strategy and links it to one or more of the recovery objectives and performance indicators outlined in Table 3. A list of study participants is also provided. End of Table 5.
|Study||Timeline||Status||Details||Rec. Obj.||Perf. Ind.||Participants|
|Acoustic and visual monitoring of shelf break between the Gully, Shortland Canyon, and Haldimand Canyon||2010-2011*|
*As put forward in the 2010 Recovery Strategy. Due to the complexity and volume of work involved in this project, it could not be completed in one year.
|In progress||An analysis of underwater acoustic recordings collected on the Scotian Slope between 2006 and 2009 was completed in 2012. The results of this analysis demonstrated that passive acoustic monitoring methods could be successfully used to study the occurrence of NBW over time. The data revealed that NBW are year-round residents of the Eastern Scotian Shelf canyons, and that the areas between the canyons are used for foraging as well as migrating between canyons.|
Days- to week-long deployments of acoustic recorders were conducted in the Gully in 2010 and 2011 to test newer units for recording NBW clicks. Between October 2012 and October 2014, these acoustic recorders were deployed at three sites for 5-7 month periods with 1-2 month breaks between deployments: 1) in the Gully, 2) between the Gully and Shortland Canyon, and 3) between Shortland and Haldimand Canyons. Beaked whale vocalization frequencies were recorded for two minutes at 15-20 minute intervals. The resulting passive acoustic data are more extensive than previous acoustic datasets and are being analyzed for NBW clicks to make more detailed inferences about the species’ presence in, and use of, these areas throughout the year. The data are also being analyzed for ambient and anthropogenic noise sources and levels. An acoustic recorder was again deployed in May 2015 in the Gully. This unit is expected to be in place until 2017.

3.3 Summary of progress
Table 6 provides a summary of the progress made toward meeting the performance indicators outlined in Table 2. Each indicator has been assigned one of four statuses:
- Not met: The performance indicator has not been met, and little to no progress has been made.
- Partially met, underway: Moderate to significant progress has been made toward meeting one or more elements of the performance indicator, and further work is ongoing or planned.
- Met, ongoing: The performance indicator has been met, but efforts will continue until such time the population is considered to be recovered (i.e. the indicator will be reported against in the next five-year progress report).
- Met: The performance indicator has been met and no further action is required.
Table 6: Table 6 summarizes the progress made toward meeting the performance indicators listed in Table 3 during the reporting period. The table contains four columns and many rows that span several pages. From left to right, the column headers are as follows: Performance indicator; Status; Comments; and Next steps/recommendations. The “Status” column is described in detail within the text of Section 3.3. Each row corresponds to one of the performance indicators and provides some commentary regarding progress to-date and areas to focus on during the next reporting period. End of Table 6.

4. Concluding statement
The information presented in Tables 4-6 provides many examples of how, and to what extent, the NBW-SSP Recovery Strategy has been implemented by DFO and its partners during the reporting period. Activities have been undertaken in support of all four recovery objectives. Half of the 16 performance indicators have been met; however, all of these will require ongoing action to maintain the progress made on recovery strategy implementation. One quarter of the performance indicators were partially met and three were not met during the reporting period. Two of the indicators that were not met related to the quantification of the rate and sources of NBW mortality.
The primarily offshore distribution of this species makes it challenging to observe and respond to incidents involving the NBW-SSP. A poster campaign is ongoing to raise awareness among ocean users about the need for information on encounters with dead, entangled, or injured whales. One of the anticipated outcomes of this campaign is an increased likelihood of dead or injured whales being reported and documented. There are also plans to evaluate how to effectively respond to offshore incidents, so that there may be a greater chance of saving an NBW in distress or retrieving a carcass for necropsy. Other elements of recovery strategy implementation that require more attention include quantifying the threat of entanglement, assessing prey composition, and measuring food chain contaminant levels. Acoustic disturbance continues to be a threat of particular concern for this population, as noise from several sources is becoming increasingly pervasive in the marine environment. Furthering our understanding of the effects of noise on this species will continue to be a high priority, as will the development of appropriate mitigation measures.
Work done by the Whitehead Lab (Dalhousie University), in partnership with DFO, has contributed significantly to addressing Recovery Objective 2. The high quality and number of digital photographs collected over the past decade, coupled with the availability of powerful photo editing software, has advanced the NBW photo-identification catalogue significantly. This has allowed for progressively more rigorous and precise estimates of population size and trend to be calculated. Regular visual and acoustic surveys have also contributed to a better understanding of abundance and distribution. While the Gully, Shortland, and Haldimand canyon habitats continue to be areas of concentration for the NBW-SSP, less is known about how the population uses other areas of the Scotian Shelf/Slope and the Grand Banks. The Action Plan for the NBW-SSP includes measures aimed at obtaining the scientific information needed to delineate the population’s range and to better understand distribution outside of the submarine canyons.
Considerable work has been done to address Recovery Objective 4, including efforts to engage ocean users directly, as well as raise awareness of the species and its threats among the public. Public exposure to this species is limited due to its predominantly offshore distribution. Through the activities profiled in this report, the NBW-SSP has been introduced to Canadians of all generations. Although it is difficult to measure the impact of outreach and education on species recovery directly, the existence value placed on the NBW-SSP by the public is expected to have long-term benefits. Targeted engagement of resource users in NBW-SSP recovery likely has more immediate effects, but these are also challenging to quantify. Methods to better understand the influence of stakeholder and public engagement on NBW recovery could be explored in the future.
Overall, progress was made toward implementing the NBW-SSP Recovery Strategy during the first five-year reporting period; particularly in advancing the understanding of the population and promoting management measures that mitigate threats to its recovery. The recovery goal, which is to “achieve a stable or increasing population and to maintain, at a minimum, current distribution”, was reached at least in part. A recent study conducted by O’Brien and Whitehead (2013) revealed a stable population trend over the period 1988-2011. The extent to which distribution patterns were maintained cannot be fully assessed since habitat use outside of the Eastern Scotian Shelf canyons (including the inter-canyon areas) is not well-studied and has not been monitored. However, the use of critical habitat and surrounding areas has been consistent over time. The work started and completed to date has built a strong foundation for continued research and successful management of this species over the next five years.
