    The Decline of the North Atlantic Right Whale

    • The “Right Whale” to kill

    – Colonial Whaling (late 1600s)

    – Pelagic Whaling (late 1800s early 1900s )

    • 5,500 – 11,000 right whales taken

    Status:

    • The most endangered large whale - about

    500 remain, population increasing by 2%

    • Recovery hampered by a low reproductive

    rate and mortality from shipping and

    fishing.

  • Adults: length 55 feet (17 metres)

    weight ~ 60-70 tons

    82% have scars from fishing gear

  • • 60,985 records & 500,000+ photographs of 657 right whales, of which 509 alive

    • How do you tell these whales apart?

    The Right Whale Catalog

  • • Gestation (pregnancy) ~12 – 13+ months

    • Lactation ~1 year

    • Rest ~1 year +

    • Single calf every 3 – 6 years, average calving interval ~3.7 years

    • Average age for 1st calving ~9 years (range 5 – 21)

    • Reproduction is hampered by a low reproductive rate

    Right Whale Calving

  • • 1980 – 2000 ~11/yr = 227 calves in 21 yrs

    • 2001 - 2014 ~ 21/yr = 298 calves in 14 yrs

    •But not all are catalogued!

  • Since 1970:

    • 28 vessel strikes (~50% of known deaths) in

    Canada and US waters

    • 21/28 (75%) of vessel strikes occurred since

    1991

    • 6 strikes (1/5th) occurred in Canadian waters

    since 1987

    The Problem of Right Whales and Vessel Strikes

  • Delilah’s death in Sept. 1992

    Mariner Awareness Program:

    1993 – Fundy Traffic (DFO) Right Whale alert and Notice to Mariners (NOTMAR)

    Right Whale conservation areas Fundy and Roseway (DFO)

    1994 – DFO published Caution Mariners pamphlet

    1995 – Right whale sightings and info on back on nautical charts (CHS/DFO)

    1995 & 1997 – Two more right whale mortalities from vessel strikes in Bay of Fundy

    Mariner Awareness alone did not solved the problem!

    Call to Action

  • Unique partnership formed between researchers and industry in 1998.

    Goal: to make things better for right whales and promote species recovery in Canadian waters by reducing the risk of vessel strikes.

    Two Options considered:

    • Rerouting of vessels around right whale distribution

    • Speed reduction

    2000 – 2002: Researchers used 12 years of right whale sighting data and 1 year of vessel traffic data to assess the probability and risk of a vessel collision with right whales.

    Vessel – whale working group

  • After amendment to the TSS 90% reduction in risk where outbound lane of TSS intersects the Conservation Area

    Highest risk: occurs where outbound lane of TSS intersects Conservation Area

    Highest density of right whales and the highest density of vessel traffic

    Before amendment to TSS – notice the overlap between outbound shipping lane and high concentration of right whale sightings.

    Right whale sightings and Bay of Fundy Traffic Separation Scheme

    The new shipping lands were moved 4 nautical miles to the east and a turn out added for wet bound traffic to avoid the highest concentration of whales.

    Which option gave the least risk? Re-routing or Speed Restriction

    Rerouting gave a 62% reduction in overall risk in the Bay.

    Transit time in outbound lane increases by ~1.4%

    Speed reduction would have given a 52% reduction in overall risk.

    Transit time in outbound lane would have increased by ~20%.

  • IMO adopted lanes 2002 Implemented by Canada 2003

    Vessel Whale working group:

    Rerouting solutions presented to Transport Canada – Issue of marine (navigational) safety

    Proposal to International Maritime Organization, sub-committee on Safety of Navigation

    International support from U.S. and others at IMO – a 1st for IMO

    Completed in the absence of domestic legislation

    Amended Fundy Lanes

  • “CALVIN”

  • • Grand Manan Basin Conservation Area

    • Roseway Basin Conservation Area

    • Amended Fundy vessel traffic lanes

    Continued Mariner Awareness Program with industry and public

    Roseway Basin Vessel Strike Stewardship

    • 2003 and 2006 – two more right whale mortalities

    • Roseway Basin: no shipping lanes

    • Considered speed reduction, recommended routes and an Area To Be Avoided

    • Used right whale sighting data, vessel reporting data to assess overlap

    • Used passive acoustics to set timeframe

    • Lowest probability of encounter with ATBA

  • ATBA designed to encompass:

    majority of whales

    area of highest risk

    • The lowest probability of encounter between vessels and whales was with an Area To Be Avoided (ATBA) i.e. re- routing

    • The boundaries of ATBA were shaped to roughly parallel vessel traffic

    • Use AIS data from Vessel Avoidance and Conservation Area Transit Experiment, determine addresses for direct communication with shipping industry (owners and operators)

    • Avoider letter – recognize those vessels avoiding the area

    • Non avoider letter – to increase the awareness of vessels continuing to transit the ATBA with the goal of achieving 100% compliance

    • 2008 - 2012 ~ 80% compliance

    • Compliance decreased slightly in 2013

  • • High quality data – long term monitoring and robust analyses

    • Involved all marine users early and often (shipping, fishing, whale watching, and public) – issue of marine safety

    • International notification to marine industry through IMO instruments, domestic Notices to Mariners and VTS

    • Timeline – 12 yrs from 1st death to amended Fundy lanes, another 5 years for Roseway Basin ATBA = 17 years

    • Develop monitoring scheme for 3 years and report back to industry results of monitoring … (20 years!)

    • 320 right whales in 1998 to 509 in 2013!

    Model of Unique Partnership

  • Reduced the potential for lethal vessel encounters with right whales

    with

    Minimal disruption to vessel operations / maintain safe navigation

    and

    High, but not perfect, compliance

    In 2009 – identified as Critical Habitat by DFO under the Species at Risk Act

    Precedent setting measures that led the way for other mitigation measures for right whales and other species in the US and worldwide

    Vessel strike risk reduction measures in Atlantic Canada

  • Policy changes to reduce vessel strikes

    • 1999 U.S Mandatory ship reporting (educational) - southeast and

    northeast

    • 2003 Bay of Fundy shipping lane shifted – IMO precedent

    • 2006 U.S. Recommended routes – southeast Florida and northeast

    Cape Cod Bay

    • 2007 Boston shipping lanes shifted

    • 2008 Roseway Basin Area To Be Avoided – IMO precedent

    • 2008 U.S. Speed rule (≤ 10 knots) and Seasonal and Dynamic

    management areas

    • 2009 U.S. Great South Channel Area To Be Avoided and amended

    lanes

    • Right whales now have more protection from vessel strikes throughout

    their Canada/US range - compliance is low in the U.S.
