Paper Parks? Why Marine Protected Areas Are Failing Sharks

1
00:00:01,140 --> 00:00:07,517
On this episode of the How to Protect the Ocean podcast, we're gonna talk about why
submarine protected areas are failing sharks.

2
00:00:07,517 --> 00:00:11,281
A protected area without enforcement is really just a map.

3
00:00:11,281 --> 00:00:12,443
It's a paper park.

4
00:00:12,443 --> 00:00:19,910
And if you care about staying informed on the ocean every weekday, hit that follow button
right now so you don't miss tomorrow's story.

5
00:00:22,466 --> 00:00:25,868
So here's the situation, here's what we've discovered, here's what's happened.

6
00:00:25,868 --> 00:00:31,270
Shark populations are declining in some MPAs.

7
00:00:31,270 --> 00:00:37,683
There was a study that was done with silky sharks and it was tracking silky sharks around
an MPA.

8
00:00:37,683 --> 00:00:42,286
It's a highly mobile predator and it demonstrates a serious gaps in MPA effectiveness.

9
00:00:42,286 --> 00:00:47,208
So essentially these silky sharks were tracked by satellite tags and researchers found
that they...

10
00:00:47,208 --> 00:00:54,181
spent significant time outside of marine protected areas, even if MPAs existed in their
range.

11
00:00:54,181 --> 00:01:04,406
So while MPAs in the Galapagos Marine Reserves do offer some refuge, the sharks often
travel beyond the safe zones into areas where intense industrial fishing happens,

12
00:01:04,406 --> 00:01:11,430
especially purse sains and long lines target tuna, where bycatch and fin trade risk
remains high.

13
00:01:11,430 --> 00:01:12,556
So having

14
00:01:12,556 --> 00:01:17,089
you know, these sharks in a uh marine protected area either tells you one thing.

15
00:01:17,089 --> 00:01:20,290
These sharks go beyond the border, so the borders have to be bigger.

16
00:01:20,290 --> 00:01:29,775
And a lot of times when you're protecting sharks, you see these massively large MPAs
happen, but they have to because they have to encapsulate the entire range of the shark.

17
00:01:29,775 --> 00:01:33,107
Now we're just talking about silky sharks, we're not talking about any other types of
sharks.

18
00:01:33,107 --> 00:01:41,804
We know great whites, we know thresher sharks, we know other, a lot of other sharks have,
hammerheads, have very large migration ranges.

19
00:01:41,804 --> 00:01:46,836
And so certain MPAs have to be built for these types of sharks.

20
00:01:46,836 --> 00:01:56,940
Illegal and unregulated fishing persists within these marine protected areas and highly
migratory species cross these MPA boundaries all of the time, not just sharks, but we have

21
00:01:56,940 --> 00:02:03,243
whales, sea turtles, all these different types of species that will actually do that.

22
00:02:03,243 --> 00:02:05,804
MPAs often fail to protect mobile predators.

23
00:02:05,804 --> 00:02:07,084
We just talked about that.

24
00:02:07,084 --> 00:02:08,917
Enforcement gaps are...

25
00:02:08,917 --> 00:02:18,444
reduces found in another study from nature communications and fishing pressure often
concentrates along the borders which we've talked about in past episodes but i'll reaffirm

26
00:02:18,444 --> 00:02:25,269
this you know it in in argentina just off the coast of argentina there's a squid species
that is highly uh...

27
00:02:25,269 --> 00:02:35,737
fished or or or sustainably fished within argentinian the exclusive economic zone of
argentina or arson of arch of of argentina my apologies

28
00:02:35,737 --> 00:02:44,843
But along the border of that exclusive economic zone, you often see fishing fleas that
line up at certain times of the season when they know that the squid will come across that

29
00:02:44,843 --> 00:02:46,014
exclusive economic zone.

30
00:02:46,014 --> 00:02:48,616
And of course, you know, that border is imaginary.

31
00:02:48,616 --> 00:02:50,708
It's not a physical border.

32
00:02:50,708 --> 00:02:59,994
So these boats can come in like across that EEZ zone or EEZ line and then come back and
then fish whatever they want.

33
00:03:00,114 --> 00:03:04,235
Enforcement has to be taken, but it's very difficult to do enforcement.

34
00:03:04,235 --> 00:03:11,088
when you have such a long area or such a large area to enforce as well as like these
fishing fleets are relentless.

35
00:03:11,088 --> 00:03:14,620
will go after these fish as soon as they cross that border.

36
00:03:14,620 --> 00:03:21,853
know, MPAs once they go once they're out of the exclusive economic zone or once these fish
are out of that, it doesn't matter if there's an MPA around there.

37
00:03:21,853 --> 00:03:26,855
Once they're out of the easy for now, hopefully the high seas treaty will help with that.

38
00:03:26,855 --> 00:03:30,541
You get extensive fishing pressure along those borders.

39
00:03:30,541 --> 00:03:37,895
Now, Global Fishing Watch did a search and did a study and they found that many MPAs show
detectable fishing activity.

40
00:03:37,895 --> 00:03:45,599
So satellite monitoring reveals and force inconsistencies and there are a lot of
transparency gaps within this type of compliance.

41
00:03:45,979 --> 00:03:53,944
So if this is the kind of clear, so we're gonna break down this information, but if you
want this information uh more and you find this helpful, make sure you hit that follow

42
00:03:53,944 --> 00:03:55,265
button for the show.

43
00:03:55,265 --> 00:03:57,776
Trying to grow this show even bigger.

44
00:03:57,776 --> 00:03:59,937
I want more people listening to Ocean News.

45
00:03:59,937 --> 00:04:09,875
And the fact that you hit that follow button if you're listening to this each and every
weekday, this helps uh grow and allow us to be in front of more and a bigger audience for

46
00:04:09,875 --> 00:04:10,596
people to get it.

47
00:04:10,596 --> 00:04:14,969
We release an episode every weekday morning, so it's really important.

48
00:04:14,969 --> 00:04:16,914
So I'm talking to you this stuff and I want to break it down.

49
00:04:16,914 --> 00:04:20,383
I want to talk to you why this stuff is so important.

50
00:04:20,464 --> 00:04:24,107
When we look at sharks, sharks regulate the food webs, right?

51
00:04:24,107 --> 00:04:25,918
They are great predators.

52
00:04:25,918 --> 00:04:28,054
They are apex predators in lot of places.

53
00:04:28,054 --> 00:04:38,180
and they will regulate the the the the way the food web works structurally the food web
has a specific structure in every unique habitat by geographical habitat around the ocean

54
00:04:38,180 --> 00:04:48,235
you have sharks a lot of times at the top or close to the top those sharks will regulate
the populations of their prey dope those prey will be predators to other prey it just goes

55
00:04:48,235 --> 00:04:57,270
down the food web and it can kind of branch out these two words could be very very complex
you remove the top predators and the prey that they eat

56
00:04:57,270 --> 00:05:06,507
get huge and they'll start putting more pressure on prey below them that prey will that
play will shrink that prey will shrink and then vice versa vice versa it just goes down

57
00:05:06,507 --> 00:05:15,113
and down and down the food web and that's what we talk about fishing down the food web is
when you start to take all those predators away and you start the top predators in the

58
00:05:15,113 --> 00:05:24,129
food web and you fish down and down and down until you get down to what plankton is that
what we're going to be eating soon it can collapse fisheries very very quickly and of

59
00:05:24,129 --> 00:05:25,660
course we don't want

60
00:05:25,678 --> 00:05:33,843
So having sharks to regulate those food webs and having them as a healthy population will
stabilize diversity, stabilize food webs, and stabilize the ocean.

61
00:05:33,843 --> 00:05:38,325
So having a declining of top predators will destabilize this area.

62
00:05:38,325 --> 00:05:44,919
A paper park creates sort of a false confidence in protection metrics.

63
00:05:44,919 --> 00:05:53,513
so having that enforcement, having that management plan, having a monitoring plan really
helps, but it requires funding.

64
00:05:54,382 --> 00:05:56,883
put up MPA together, are we designated MPA?

65
00:05:56,883 --> 00:05:57,984
That's just the beginning.

66
00:05:57,984 --> 00:06:00,305
It is a tough process.

67
00:06:00,305 --> 00:06:08,590
If you've watched any of this episode before, if you've listened to any of the How to
Protect the Ocean podcast, from the beginning when I started this back in 2015, I've

68
00:06:08,590 --> 00:06:13,252
talked about how hard it is and how long it takes to designate a protected area.

69
00:06:13,252 --> 00:06:16,194
The larger the area, the harder it is to designate.

70
00:06:16,194 --> 00:06:20,556
But that is just the beginning of the journey, right?

71
00:06:20,556 --> 00:06:22,797
Unfortunately, it takes a long time to do.

72
00:06:22,797 --> 00:06:27,377
You know, I often use the analogy of starting a podcast.

73
00:06:27,377 --> 00:06:32,477
When I create a podcast, when I record, I do the research, I do the recording, it's a lot
of work.

74
00:06:32,477 --> 00:06:42,577
I come in, I record this episode, I try and keep it within an entertaining way, and I try
and keep it within a good timeline so that everybody can listen to it, and then I have to

75
00:06:42,577 --> 00:06:43,457
advertise it.

76
00:06:43,457 --> 00:06:47,137
And a lot of times, once I publish it, I'm like, oh, my work here is done.

77
00:06:47,137 --> 00:06:48,331
It's not done.

78
00:06:48,331 --> 00:06:56,116
then i have to market it i have to advertise after put in front of different people so
that they have a chance to listen to it if they want to listen to it i have to do the work

79
00:06:56,116 --> 00:07:05,473
at the continued to the work over and over and over again after refine my process to find
new audiences and to get if i want to grow my show if i want my show to be effective in

80
00:07:05,473 --> 00:07:15,299
making sure that people are aware of what's happening in the ocean and how they can live
for a better ocean but if i just stop at the publication part if mpa stop at the

81
00:07:15,299 --> 00:07:18,059
designation part of managers don't go through with it

82
00:07:18,059 --> 00:07:22,991
then you are going to feel this false sense of protection and have a paper park.

83
00:07:22,991 --> 00:07:28,533
And all those protection metrics are gone if you don't enforce them and you don't regulate
them.

84
00:07:28,653 --> 00:07:33,636
So, the big key question, when protection exists on paper only, does it count?

85
00:07:33,636 --> 00:07:36,277
In a way, it does, in a way, it doesn't.

86
00:07:36,277 --> 00:07:38,558
The overall is no, it doesn't.

87
00:07:38,558 --> 00:07:47,301
But when you first start to designate an area because it's so difficult to designate,
sometimes that first process being a paper park could help.

88
00:07:47,544 --> 00:07:50,555
However, it doesn't mean it should stay like that forever.

89
00:07:50,555 --> 00:07:52,086
It should be as quickly as possible.

90
00:07:52,086 --> 00:07:55,137
Managers should work to make sure that those areas are enforced.

91
00:07:55,137 --> 00:07:56,477
We get funding and stuff.

92
00:07:56,477 --> 00:08:03,140
So to prevent the paper parks, when you designate, make sure that there is a constant
thing of funding.

93
00:08:03,140 --> 00:08:08,762
People are doing, countries are doing some really creative ways of funding protected
areas.

94
00:08:08,762 --> 00:08:17,313
The island of Newey in the South Pacific, they have done a very good campaign of getting
people to invest in those protections

95
00:08:17,313 --> 00:08:25,117
by like I could pay for a square kilometer to help manage a square kilometer for 20 years
if I pay like 200 bucks US.

96
00:08:25,117 --> 00:08:27,438
That's a great, great commodity for me.

97
00:08:27,438 --> 00:08:32,461
I don't own any of that, but I know that that area is protected and I had a piece in
protecting that.

98
00:08:32,461 --> 00:08:33,511
I had a part of it.

99
00:08:33,511 --> 00:08:36,483
I don't own any of it, but I know people are gonna be protected.

100
00:08:36,483 --> 00:08:40,886
That area is gonna be protected and more people that pay for it gets protected as well.

101
00:08:40,886 --> 00:08:46,849
What I love about the Island of Nui, they kept a number of different acreage for their own
people.

102
00:08:46,849 --> 00:08:51,393
to invest in to protect because that it can feel like they're part of it, right?

103
00:08:51,393 --> 00:08:53,234
I don't, I've never been to the island of Newey.

104
00:08:53,234 --> 00:08:54,679
I don't know anybody in the island of Newey.

105
00:08:54,679 --> 00:09:03,222
I know a few people actually, cause I've interviewed them before, but that create, that
campaign has really helped in ensuring that there's funding to monitor and manage that

106
00:09:03,222 --> 00:09:06,375
marine protected area for 20 years down the road.

107
00:09:06,375 --> 00:09:09,297
I'm not saying that this will work for everybody, but this could work.

108
00:09:09,297 --> 00:09:16,577
And I'll be honest, I am on a push for people to invest more in local conservation as well
as

109
00:09:16,577 --> 00:09:27,386
conservation abroad, instead of getting a bracelet back or something else back, you know
that you've actually protected this area or you've helped protect this area, you helped to

110
00:09:27,386 --> 00:09:29,187
contribute to protect that area.

111
00:09:29,187 --> 00:09:31,899
All of these things encapsulate that.

112
00:09:31,899 --> 00:09:42,328
what my goal is is to bring light and cover and accelerate the amount of information
that's coming out of those local areas that people get to uh donate to and get to

113
00:09:42,328 --> 00:09:43,159
contribute to.

114
00:09:43,159 --> 00:09:46,402
So it's a lot of fun that can happen, but Marine Protect Areas need funding.

115
00:09:46,402 --> 00:09:47,783
They need management protections.

116
00:09:47,783 --> 00:09:49,583
They need people dedicated to enforce.

117
00:09:49,583 --> 00:09:53,925
They need to make sure that these areas are protected fully.

118
00:09:53,925 --> 00:10:02,008
Not just having lack of transparency, not having people go in, turn off their GPS if
they're fisheries and they start fishing in there.

119
00:10:02,008 --> 00:10:03,038
That just doesn't work.

120
00:10:03,038 --> 00:10:04,439
You need to make sure that that works.

121
00:10:04,439 --> 00:10:06,330
There's a lot of work that goes into an MPA.

122
00:10:06,330 --> 00:10:10,541
It's different than a land protected area because it's harder to cover.

123
00:10:10,541 --> 00:10:15,613
It's a lot of times it's in isolated places and it costs a lot to protect.

124
00:10:15,617 --> 00:10:18,958
Protection must not be measurable, but it must be symbolic.
