Protecting Whale Migratory Corridors: A Call to Action · How To Protect The Ocean

0:00
Scientists have been yelling at the top of their lungs for decades
0:04
to get whale migratory corridors protected so
0:08
that these whales can be protected from their tens
0:11
of thousands of kilometers of where they travel summers and
0:14
winters, and make sure that specific areas, special areas
0:18
are protected where they feed, where they breed, where they rear their
0:21
young, and where they need best protection. And now with
0:24
the melting of the Arctic and Antarctic, it's getting more
0:28
and more sort of critical to get these
0:31
corridors protected and to help these whales out. We're going to talk about that
0:35
on today's episode of the How to Protect the Ocean podcast. Let's
0:38
start the show. Hey
0:43
everybody, welcome back to another exciting episode of the How to Protect the
0:47
Ocean podcast. I'm your host, Andrew Lewin, and this is the podcast where you find out what's
0:50
happening with the ocean, how you could speak up for the ocean, and what you can do
0:53
to live for a better ocean by taking action. And
0:57
I am back from a vacation, a well-deserved vacation, and
1:01
I'm rested. I'm a little bit more tan. I'm not sure if you can see
1:04
that. Lots of sun, went up to a cottage with the family and some
1:07
friends, and we had a great time, great weather. Love
1:11
it up in Northern Ontario, sort of Northern Ontario,
1:15
down near Georgian Bay and Parry Sound. It was a great time, really,
1:19
really loved it, and look forward to going back next year.
1:22
So but now that I'm back and rested, I'm relaxed, I've
1:25
got a new sort of energy about me and I'm ready to give
1:29
you ocean news. And today's ocean news has to do with
1:33
protecting whales and whale corridors. If you don't know what a
1:36
whale corridor is, is whales will go and they will migrate from
1:40
one place to another over the year. So for instance, humpback whales
1:43
will migrate from Hawaii where they go in the winter to
1:47
Alaska where they go in the summer. so that they can
1:51
feed and breed and do all the things that they need to do along the
1:54
way. And they will feed and go into special areas,
1:59
I like to call them, and a lot of scientists like to call them distinctive areas, so that they
2:02
can stop over just while they're going on these corridors.
2:05
Now, these corridors, they're stressful times. It's a long way to
2:09
go. It's a lot of body to move through the water. And
2:13
these animals, these whales, need the protection
2:17
from other sort of human activities, especially shipping, especially
2:21
fishing, all these different types of activities that
2:25
could cause harm that are human-induced, direct human-induced. So
2:29
the call has been there for a long time. And I'm gonna take
2:33
you back in time a little bit. I'm gonna take you back. to
2:37
the early 2000s when I was a graduate student and
2:40
I was doing my work on marine protected areas. My supervisor was
2:43
Dr. John Roth. I almost forgot his name. It's been a
2:47
long time. My supervisor was Dr. John Roth at Acadia University. He
2:50
had worked at the University of Guelph for quite a long time. Great guy,
2:54
really great supervisor. He, along
2:59
with John Day from the Great Barrier Reef Marine Park at the time, wrote
3:03
a document for World Wildlife Fund, who
3:06
is the author of the call now
3:10
for this new protection of whale blue
3:13
corridors. John
3:17
Day and John Roth, they wrote this document that
3:21
talked about two different types of marine protected areas
3:24
that we needed. And I've talked about this before, but I'm going to go over it because
3:28
if you're new to this podcast, first of all, welcome. And if you're not
3:31
new, you've heard this before, but you probably want to hear it again because it takes
3:35
a while to get into people's systems because it's not something we talk about each
3:38
and every episode. But essentially what you have is you have two types
3:42
of areas that you like to protect. You have the representative areas and you
3:45
have the distinctive areas. Now the representative areas are areas where
3:49
you'd expect to see, you know, fish, invertebrates
3:53
like crabs, lobster, octopus, squid,
3:58
shrimp, those types of things, those types of animals. And then
4:01
you have, that's where you find it. So you find those representative areas,
4:04
what you would expect to see in an area. So along the
4:08
Nova Scotian Shelf and along the Bay of Funny, you're expected to see a
4:11
certain type of animal. And sometimes you
4:15
expect to see assemblages of these animals. So communities of
4:18
these animals that are getting together, that are dominated by one
4:22
or two species, and then they have the rest that kind of fall in line. Those
4:25
things will change every once in a while, those areas, but overall, those
4:29
areas stay the same. The research that I did when I was a graduate student
4:32
was looking at macroinvertebrate areas, so like I
4:35
said, crabs, lobsters, shrimp, squid, octopus,
4:39
you know, that type, those types of animals. And then to see over
4:42
a four-year period, what was the representative areas? How many
4:46
were there? What was it dominated by? Did they change over
4:49
those four-year periods? And I'm not going to go into my
4:53
thesis, but essentially, we had four, sometimes five typified
4:57
areas. And so those are the ones that we expected to see. Now,
5:00
you have those types of assemblages. If you do the workup, you
5:03
have it for fish, demersal fish, which was done. by somebody
5:07
previous to me, and then you have all over the country you'll
5:10
have these types of assemblages and representative areas of what
5:14
you'd expect to see in particular areas. Now,
5:18
the distinctive areas is what we're going to talk about today. The distinctive areas are
5:22
areas that are not normally found. It's kind of
5:25
like special areas. And they're usually typified by an activity or
5:29
something that's special in the area. So it could be a nursery habitat.
5:33
It could be a breeding ground, spawning area, depending on the species.
5:37
It could be an upwelling that provides a lot of food
5:40
for fish, sea turtles, whales, dolphins,
5:45
seabirds, sharks, tuna, like all these different types of
5:48
animals that will congregate and aggregate in one area
5:52
because it's a great stop along their migration period,
5:55
right, or their migration corridor. See where I'm getting at, how it ties into
5:59
this? Now there is an article on www.ca, so
6:02
the Canadian Wildlife Federation, Foundation, I'm getting the wrestling federation,
6:06
WWF, which
6:12
is now WWE, World Wildlife Foundation. And
6:15
essentially what they did, they came up with this article for a new call
6:19
for protecting whale migratory
6:23
corridors, so specially managed areas. These
6:26
are specific areas that are distinct Because they
6:29
are these corridors that are necessary for
6:33
marine mammals, for whales to travel up
6:37
or travel down depending on the time of the year. These
6:40
are really important areas and we've seen these
6:44
types of corridors protected before. Not necessarily directly,
6:49
as in like here's where the whales are, but we've actually seen human
6:53
activities be managed around those areas. So for
6:56
instance, the North Atlantic right whale distribution
7:01
area was managed through shipping lanes. So the shipping lanes
7:05
of the ports that were along those areas where this North Atlantic right whale
7:09
would travel and migrate. Those were controls. So
7:12
they would look at, hey, here are the traditional shipping
7:16
routes. Here are where the North Atlantic right whales go based
7:20
on their patterns. And it would be a lot of data. So looking at airborne
7:24
sort of observations. And there would be autonomous
7:29
drones and things like that that would actually travel and spot and
7:32
preserve these types of animals. And
7:35
then we would map where they are. So we kind of knew their patterns. And
7:39
they usually stick to specific patterns because they want to go to
7:42
these distinctive areas at certain times of the year so that they
7:45
can feed and rest and recoup and then move along their
7:49
whale corridor. So the North Atlantic right whale would start off in
7:52
Jacksonville, Florida, in and around there. And they'd end up
7:56
sort of north of Maine. And they
7:59
would get into Canada. and so forth and so and
8:03
now the Gulf of St. Lawrence and you know those needed
8:06
to be protected now there's a lot of shipping that goes along there there's the transatlantic area
8:10
that gets that there's a lot a ton of shipping and we know
8:14
the mapping of that through AIS and so we
8:17
know where these and where these boats go so we can say
8:21
hey for the time during this time the boats
8:24
are going to be the shipping lanes are going to be here and that's where we're going to map them
8:27
out and you have to follow that so all shipping all any type of
8:30
shipping vessel that comes through has to go through those areas and
8:34
so it decreased in noise it decreased in ship
8:38
strikes and that was the idea the help now We
8:42
know that migratory corridors can shift based on
8:45
where the upwellings are, where the special areas are, how
8:49
the temperature is, how the currents are going. It really
8:52
depends on where these animals will go. And so these shipping
8:57
lanes need to be managed on an annual basis or even semi-annually
9:01
to make sure that the migratory routes of
9:05
these ships and these whales do not
9:08
conflict. And so that was just with one species, an
9:12
endangered species, or critically endangered species. Now
9:15
we're talking about, in this article, they're talking about the gray whales as
9:19
an example, which is the Pacific gray whale population, which
9:22
goes from Southern California all the way up to Alaska. In
9:26
the summers, they'll go up to Alaska to feed on fish. They'll
9:29
go up there. There's plenty of fish to get.
9:32
They feed and they stock up on all these fat deposits and
9:36
things, and then go back down to do their breeding and so
9:39
forth. And it's a very important population. It's
9:43
a huge population. But unfortunately, as
9:47
the Arctic is melting,
9:51
and there's more shipping that's happening in
9:55
these areas, this poses a huge
9:58
risk for these whales. This is not something that's
10:02
easy. It's not just gray whales. You get humpback whales as well. There's bowhead whales
10:06
and beluga whales that are up there. And there are a number of seals and
10:09
sea lions that are up in the Arctic that can be affected by
10:12
these ships, that could be affected by the warm water, the lack of
10:17
sea ice. Now, when you have lack of sea ice, you have lack of plankton. So
10:20
these baleen whales that are up there looking for plankton, you're not going to
10:23
get as much phyto and zooplankton. So
10:27
there's always there's always a loss of food. There's a loss of production and
10:30
fish as more and more people are going to be fishing in these areas. There's
10:34
going to be a loss of fishing in that if it's not managed properly. And
10:37
let's be honest. this is not that great.
10:40
And at the end of a long migration that these gray whales and humpback whales
10:44
are taking, it's believed to be like
10:47
one of the primary causes of unusual mortality event
10:51
declared by the US government between the years of 2018 and 2021 for
10:56
the gray whales, during which time more than 500 malnourished
11:00
gray whales washed up along the coast of these blue corridors. The
11:03
size of the gray whale population dropped by half from around 28,000 to 14,000. That's
11:09
a huge huge loss when we're looking at species that are
11:13
long-lived species. This is these are species where It
11:16
takes a long time for them to get to the size that they are, to
11:20
get to reproducing, to get them healthy. And then you have other things
11:23
like climate change. You have plastic pollution that can affect them. You
11:27
have fishing, where they can get entangled by fishing gear like crab
11:30
pots and lobster pots, as well as nets like gill
11:33
netting and things like that, long lining. There's a lot of
11:37
different things that can affect them. And then, of course, there's shipping. And
11:40
there's noise that throw off their migratory patterns. So
11:44
many things need to be managed around these
11:47
whales that are human-induced that we have to
11:51
be able to manage those. So these corridors, this call from
11:54
WWF to manage these corridors is extremely important
11:58
and of course is the timing can't be more
12:02
perfect. I mean, the timing would have been perfect. It was done in the early 2000s or even before
12:05
that when there was a call to do that. But right now it's needed,
12:09
especially now because, you know, things have just
12:12
doubled, you know, over the last 10 years in terms of, you
12:16
know, volumes like shipping volumes and
12:20
fishing fleets and things like that. have pushed deeper into
12:24
Arctic waters. And so, you know, the
12:27
time is now to recognize migratory corridors as
12:31
essential components of ocean connectivity and
12:34
marine species conservation, and to include these in
12:37
ocean protection measures. Now, the timing of this call is
12:41
kind of timed to the, there's a
12:44
new meeting in October 2024, of
12:48
the Conference of the Parties to the Convention of
12:52
Biological Diversity. It'll be the 16th meeting, where
12:55
this is an internationally recognized convention on
12:59
biological diversity. It's ratified by
13:02
a lot of countries, including Canada and the US, as well as other countries around
13:06
the world. And so there has been
13:10
sort of this international pressure for these countries to
13:13
do what's possible to protect these areas. And now
13:16
when there's that, there's the International High Seas Treaty. There's
13:24
also the need to protect 30 by 30, so 30% of
13:28
land and oceans by 2030. There is
13:31
a lot of pressure for countries such as Canada and the U.S., especially when we're
13:35
talking about the Great Whales, to protect their waters, including whale
13:38
corridors. So not just you know these representative areas
13:42
where there are some interesting areas or what we expect to see
13:45
but also not just hydrothermal vents where nobody's
13:49
really been in that area in the past so it's a little bit of low-hanging fruit.
13:53
These corridors are going to be difficult to put in as marine protected areas
13:57
but they're going to be necessary and they're going to shift As
14:01
climate change changes everything with wind patterns and currents,
14:05
migratory corridors are going to change. That means shipping lanes
14:08
are going to have to change. The fishing fleet is going to have to change over
14:12
time. And obviously, the way we manage water
14:16
quality in terms of plastic pollution and nutrients and so forth, that's
14:19
going to have to be really managed as well. There are a lot
14:23
of things that need to be managed, but the big initial thing is let's protect these corridors,
14:26
whether they be at certain times of the year or they're all
14:30
year round, something has to be done. And I'll be honest, I
14:33
agree with WWF here. I feel like this call, you know,
14:36
WWF is where I'd worked with, you know, on my, when I did my
14:40
research on graduate research at a Canadian university, they've been
14:43
working on the East coast and West coast and Arctic, you
14:47
know, to get more marine protected areas for decades. And
14:50
it's something that they've been pushing for a long time into the call for this. you
14:53
know, during this time when there's going to be a meeting in October is going
14:57
to be really important. It's not going to be the last that we hear of
15:00
this. I'm going to try and get some of the contacts at WWF to come on the
15:03
show to be able to talk more about this and why the
15:06
timing now, why October 24th, why the 16th
15:10
meeting on the conference of the parties to the convention on biological diversity.
15:14
in October 2024. Why are we going to be worried
15:17
about this? Obviously, there's going to be other things that are going along in the world. You
15:21
know, the US election is going to happen too. But we need countries
15:25
to really put forth solutions and to act
15:28
on these protections. And hopefully, these corridors can be a big
15:32
part of the conversations that go on at the convention. And
15:35
it's going to be something that we need to talk about. Now, one thing
15:39
that's interesting, too, in terms of marine protected areas and connectivity, one
15:44
of the things that I was going to do in my PhD, I never ended up doing it. I decided to
15:47
go to just kind of start my life and start all
15:50
the things that I need to do during my time as
15:54
a marine scientist. But one of the things I was going to do is look at connectivity
15:58
in terms of how these areas, these network
16:02
of marine protected areas, just similar to the Great Barrier Reef, how
16:05
we could put that elsewhere and how everything is so unique in
16:09
different spots and how it would be and how like the politics would
16:12
work and how the stakeholder engagement work with fisheries and
16:16
other ocean users as well as protecting habitats and
16:20
environments. One of the things I was going to look at was that connectivity between
16:23
the different areas in a marine protected network. area
16:27
network. give
16:45
way to larvae and eggs. And they would
16:49
go through the currents. And some would go really far. Some wouldn't go that far.
16:53
Some would go like hundreds of kilometers. Some would go maybe a kilometer. Some
16:56
would go tens of kilometers. And so we would look at where,
17:00
based on models, we would look at where those areas were. And that's
17:03
how we kind of did our, that was how we were
17:06
going to do our prediction of where specific areas needed to
17:09
be in our network. I never ended up going through it, of course other people have
17:13
and there's been lots of research on that and it's been really cool to
17:16
see. Paul Snellgrove is a really big player in that. When I
17:20
was at Acadia University and I was going to go to Dalhousie to
17:23
do that, it was quite interesting work and I'm looking forward to
17:27
catching up and seeing what's happening with that. The ocean
17:31
is connected, you know, it's three-dimensional. There's a water column
17:34
to worry about, there's the depths, there's the surface, and
17:38
everything in the middle, and it's very difficult to manage, very complex system,
17:42
and we have to be careful of how we manage it, but one thing we know is we need
17:45
to manage it. We need to put more of these sort
17:48
of legislative tools in place to be able to protect them, especially
17:52
over international boundaries, especially when we talk about complex migratory corridors
17:56
that go over boundaries, multiple boundaries, whether they be state,
18:00
provincial boundaries, or even international boundaries. These
18:03
are things that we need to talk about. These are things that we need to meet
18:07
on. And there are regions like the Gulf of
18:10
Maine, It has a committee that looks at that
18:13
on the East Coast of North America. I'm sure they have some on
18:17
the West Coast and the Salish Seas. And it's
18:20
really interesting to see how these are managed by each country and how
18:24
a combination of countries manage these corridors or how they will manage these
18:28
corridors or just conservation in general. But I want to kind of just give you an update
18:31
on that and let you know about these corridors and this call for more
18:35
protection of these corridors. It's obviously needed, especially now with
18:38
the melting of the Arctic, for these whales, these gray whales,
18:42
as well as others. And so something we need to keep an
18:45
eye on. So I thought I would share that
18:48
story with you. I'd love to hear what you think. You can go on
18:52

19:06
just kind of get in touch with me, you can just hit me up on Instagram, DM me
19:10
at HowToProtectTheOcean. Let me know your thoughts on these corridors and
19:13
the protection and how you would protect them. But I would love to
19:16
hear from you about these episodes, so don't be
19:19
shy. Feel free to reach out. I'd love to have a conversation with
19:23
you, because that's what this episode is all about. It's what this podcast is all about, starting
19:26
a conversation about the ocean, sharing news, and getting you to
19:30
listen to news and getting your feedback on it. So thank
19:33
you so much for listening to this episode of the How to Protect the Ocean podcast. I'm
19:37
your host, Andrew Lewin. Have a great day. We'll talk to you next time, and
