1
00:00:14,200 --> 00:00:19,480
In these dark, ancient forests
lives a creature of legend.
2
00:00:23,080 --> 00:00:25,880
This is not an albino
or polar bear,
3
00:00:25,880 --> 00:00:30,600
but a rare North American
black bear known as a ghost bear.
4
00:00:33,600 --> 00:00:37,000
This white bear is a mother
with two black cubs.
5
00:00:40,720 --> 00:00:44,640
A bear family like this can be
found in only one place on Earth.
6
00:00:46,160 --> 00:00:49,120
The rainforest islands
on the west coast of Canada.
7
00:00:51,680 --> 00:00:55,200
My name is Jeff Turner and I'm
a Canadian wildlife film-maker.
8
00:00:56,520 --> 00:01:00,560
Alongside my own family, I'm heading
into this wilderness to tell
9
00:01:00,560 --> 00:01:02,480
the story of these special bears.
10
00:01:04,520 --> 00:01:07,160
There's a lot at stake
for this bear family.
11
00:01:07,160 --> 00:01:10,800
They only have a few critical
months to find enough food to
12
00:01:10,800 --> 00:01:12,880
survive next winter's hibernation.
13
00:01:15,320 --> 00:01:16,720
And they're not alone.
14
00:01:18,040 --> 00:01:20,920
Hungry wolves...
15
00:01:20,920 --> 00:01:23,680
and much larger bears
share their island home.
16
00:01:25,040 --> 00:01:28,480
It's going to take all the skills
of this mother bear to get her
17
00:01:28,480 --> 00:01:31,120
cubs through the many
challenges they'll face.
18
00:01:34,040 --> 00:01:36,680
This is their remarkable story.
19
00:01:52,960 --> 00:01:57,240
Canada's ghost bears live on
the west coast, in an area
20
00:01:57,240 --> 00:02:00,000
known as the Great Bear Rainforest,
21
00:02:00,000 --> 00:02:02,880
part of the world's largest
temperate rainforest.
22
00:02:06,760 --> 00:02:08,600
Here, the North Pacific Ocean
23
00:02:08,600 --> 00:02:11,440
meets the coastal mountains
of British Columbia.
24
00:02:14,640 --> 00:02:18,680
This is one of the most productive
landscapes on the planet,
25
00:02:18,680 --> 00:02:22,920
and the life here is sustained
by an abundance of fresh water.
26
00:02:44,960 --> 00:02:47,720
The Great Bear Rainforest
shelters thousands of different
27
00:02:47,720 --> 00:02:49,960
species beneath its branches...
28
00:02:52,480 --> 00:02:55,760
..but the one that we've come
here to find, the most famous
29
00:02:55,760 --> 00:02:59,280
and elusive, lives
deep within the forest.
30
00:03:00,680 --> 00:03:04,680
This isn't my first time I've been
here looking for ghost bears.
31
00:03:04,680 --> 00:03:07,480
25 years ago, my wife Sue and I
32
00:03:07,480 --> 00:03:10,720
were the first people to ever
make a film about these bears.
33
00:03:13,320 --> 00:03:18,040
We had some amazing experiences
and it changed the way
34
00:03:18,040 --> 00:03:21,200
I have understood and worked
around bears ever since.
35
00:03:23,440 --> 00:03:25,600
Today, we're heading to a spot
36
00:03:25,600 --> 00:03:28,360
where a ghost bear has been
seen in recent years.
37
00:03:30,440 --> 00:03:33,640
Although any bear could be
frightened by human presence,
38
00:03:33,640 --> 00:03:36,680
experience has taught me
that if you're relaxed,
39
00:03:36,680 --> 00:03:38,840
the chances are
the bears will be, too.
40
00:03:43,520 --> 00:03:47,920
And when we find her, this female is
just awakening from a long sleep.
41
00:03:52,720 --> 00:03:55,840
White black bears can
occur in other places,
42
00:03:55,840 --> 00:03:59,560
but it's one in a million
odds, whereas here,
43
00:03:59,560 --> 00:04:02,280
because these bears have been
isolated on these islands for
44
00:04:02,280 --> 00:04:06,440
so long, about one in ten
black bears are white.
45
00:04:10,480 --> 00:04:14,280
This year, she's come out of
the den with two little cubs
46
00:04:14,280 --> 00:04:16,240
that, unlike her, are black.
47
00:04:18,400 --> 00:04:22,200
The genes that create white
fur are not always expressed,
48
00:04:22,200 --> 00:04:25,600
and a ghost bear mother is as
likely to give birth to black cubs
49
00:04:25,600 --> 00:04:27,720
as she is to white ones.
50
00:04:33,560 --> 00:04:37,360
Getting both her cubs through their
first year will be a challenge.
51
00:04:40,360 --> 00:04:44,720
The main risk to cubs comes
from other bears and wolves,
52
00:04:44,720 --> 00:04:48,320
so when they're small, she'll
keep them back here in the forest.
53
00:04:52,000 --> 00:04:55,640
It's safer here because there's
relatively little to eat,
54
00:04:55,640 --> 00:04:58,080
and most animals are
out on the coast,
55
00:04:58,080 --> 00:05:02,200
where one of the year's greatest
feasts is getting underway.
56
00:05:04,320 --> 00:05:08,800
Hundreds of kilometres of shoreline
are covered with sticky, white eggs.
57
00:05:12,160 --> 00:05:15,160
Creatures from around the region
are here to take advantage
58
00:05:15,160 --> 00:05:16,680
of the abundant food.
59
00:05:18,040 --> 00:05:20,720
This hungry male bear could
easily kill the cubs.
60
00:05:23,440 --> 00:05:25,480
But right now, he
seems pretty content
61
00:05:25,480 --> 00:05:27,600
with just licking up
the rich eggs.
62
00:05:33,440 --> 00:05:37,440
Wolves are also a threat to the
cubs, and they're here, too.
63
00:05:46,880 --> 00:05:50,400
At this time of year, they'll spend
hours eating the rich eggs
64
00:05:50,400 --> 00:05:53,840
while trying not to ingest too
much of the seaweed underneath.
65
00:05:57,240 --> 00:06:00,080
All these eggs come
from Pacific herring
66
00:06:00,080 --> 00:06:02,440
that have come up from
deep water to spawn.
67
00:06:04,920 --> 00:06:08,480
Male herring broadcast
their sperm into the water,
68
00:06:08,480 --> 00:06:10,040
turning it milky white.
69
00:06:15,880 --> 00:06:18,280
This attracts females to the area,
70
00:06:18,280 --> 00:06:21,200
who deposit their sticky eggs
onto the vegetation.
71
00:06:22,280 --> 00:06:25,560
Each female can lay up
to 40,000 eggs.
72
00:06:27,200 --> 00:06:31,120
There's a pheromone in the sperm
that stimulates both the males
73
00:06:31,120 --> 00:06:34,160
and females into a frenzy
of spawning activity.
74
00:06:36,880 --> 00:06:41,320
Herring are the most abundant
fish on the coast,
75
00:06:41,320 --> 00:06:45,280
providing rich pickings for any
animal that can take advantage.
76
00:06:49,440 --> 00:06:51,200
Like these Steller sea lions.
77
00:06:52,720 --> 00:06:56,520
The big males can eat up
to 70kg in a day.
78
00:06:59,200 --> 00:07:01,520
DRAMATIC MUSIC
79
00:07:22,600 --> 00:07:26,280
The herring spawn is one of the most
important events of the year...
80
00:07:30,480 --> 00:07:33,120
..but our white bear mother
has not been able to take
81
00:07:33,120 --> 00:07:36,000
advantage of this spring feast.
82
00:07:36,000 --> 00:07:39,960
For now, she's continuing to
keep her cubs hidden away.
83
00:07:44,880 --> 00:07:46,880
They do seem nervous,
84
00:07:46,880 --> 00:07:50,280
but it's not because there
are wolves or other bears around.
85
00:07:54,680 --> 00:07:57,640
We are the first people that
these cubs have ever seen...
86
00:08:01,320 --> 00:08:03,800
..and even though
these cubs seem shy,
87
00:08:03,800 --> 00:08:06,240
we know what's possible
in a relationship
88
00:08:06,240 --> 00:08:08,000
between humans and bears.
89
00:08:11,080 --> 00:08:15,000
25 years ago, we lived side-by-side
with the bears of the
90
00:08:15,000 --> 00:08:18,880
Great Bear Rainforest, when our
daughter Chelsea was just a baby.
91
00:08:18,880 --> 00:08:21,000
SHE BABBLES
92
00:08:22,640 --> 00:08:26,120
We quickly came to realise
that these bears had never
93
00:08:26,120 --> 00:08:27,760
encountered people before.
94
00:08:28,960 --> 00:08:32,160
Over time, we were able
to gain their trust,
95
00:08:32,160 --> 00:08:34,280
so that they were
comfortable allowing us
96
00:08:34,280 --> 00:08:37,080
close enough to get a
special view of their world.
97
00:08:40,960 --> 00:08:44,920
Growing up with bears as her
neighbours became normal to Chelsea.
98
00:08:46,560 --> 00:08:48,720
CHELSEA: I don't remember
being here as a child,
99
00:08:48,720 --> 00:08:51,280
but the experience must
have rubbed off on me,
100
00:08:51,280 --> 00:08:56,000
because today, I feel instinctively
comfortable around bears.
101
00:08:56,000 --> 00:08:59,440
It's really special to be able
to share this again with my dad,
102
00:08:59,440 --> 00:09:02,840
only this time, I know how
lucky I am to have such close,
103
00:09:02,840 --> 00:09:04,800
personal encounters with bears.
104
00:09:09,120 --> 00:09:12,160
Looking at her, this
mother bear seems thin.
105
00:09:12,160 --> 00:09:13,720
She needs to build herself up
106
00:09:13,720 --> 00:09:16,960
if she's going to get her cubs
through their first summer.
107
00:09:21,600 --> 00:09:25,680
Black bear mothers produce
milk that is 30% fat,
108
00:09:25,680 --> 00:09:28,760
some of the richest milk of
any land animal in the world.
109
00:09:31,520 --> 00:09:34,480
And she's had to do this
with only plants to eat.
110
00:09:36,760 --> 00:09:40,200
Since coming out of the den,
she's been slowly losing weight.
111
00:09:42,960 --> 00:09:45,880
She needs high-protein food,
112
00:09:45,880 --> 00:09:48,600
but she'll have to wait
until the salmon arrive.
113
00:09:55,920 --> 00:09:58,000
Waiting in the forest does offer her
114
00:09:58,000 --> 00:10:02,000
and her cubs continued sanctuary,
but it must be hard to stay back
115
00:10:02,000 --> 00:10:05,040
from the coast, where the
pickings are much richer.
116
00:10:08,040 --> 00:10:11,720
Other inhabitants of these
islands can take full advantage
117
00:10:11,720 --> 00:10:13,840
of what this place has to offer.
118
00:10:17,800 --> 00:10:20,480
The Great Bear Rainforest
lies adjacent to the
119
00:10:20,480 --> 00:10:24,000
North Pacific Ocean,
one of the richest in the world.
120
00:10:26,720 --> 00:10:30,880
The wolves have readily adapted to
life in this marine environment.
121
00:10:33,440 --> 00:10:36,360
They are more sea wolves
than timber wolves.
122
00:10:39,720 --> 00:10:43,000
They are genetically distinct
from their cousins on the mainland
123
00:10:43,000 --> 00:10:45,680
and are incredible swimmers.
124
00:10:45,680 --> 00:10:49,600
They've been seen travelling up
to 12km between islands.
125
00:10:50,680 --> 00:10:52,640
SOMBRE MUSIC
126
00:11:06,760 --> 00:11:11,200
Most of the food these wolves
eat comes from the sea,
127
00:11:11,200 --> 00:11:12,880
but they also eat bears.
128
00:11:14,680 --> 00:11:18,320
A wolf pack kills at least
one or two bears a year
129
00:11:18,320 --> 00:11:21,120
in the Great Bear Rainforest.
130
00:11:21,120 --> 00:11:24,240
There's a good reason the mother
bear prefers the forest,
131
00:11:24,240 --> 00:11:26,160
even though there's less to eat.
132
00:11:30,640 --> 00:11:32,920
But with summer's imminent arrival,
133
00:11:32,920 --> 00:11:36,080
she shouldn't have to wait much
longer for a decent meal.
134
00:11:38,680 --> 00:11:42,480
Millions of salmon are migrating
from their distant offshore
135
00:11:42,480 --> 00:11:47,000
feeding grounds, returning to the
rivers where they were born,
136
00:11:47,000 --> 00:11:48,640
to spawn and then die.
137
00:11:54,720 --> 00:11:59,000
Many will swim hundreds
of kilometres inland,
138
00:11:59,000 --> 00:12:00,880
deep into the heart of the forest.
139
00:12:07,640 --> 00:12:11,600
And for some, it will mean
they have to travel underground.
140
00:12:15,200 --> 00:12:19,480
Underlying huge parts of the coast
is a type of bedrock that is
141
00:12:19,480 --> 00:12:23,440
so porous and permeable that
water flowing on the surface
142
00:12:23,440 --> 00:12:25,640
will suddenly disappear into a hole.
143
00:12:30,080 --> 00:12:33,960
The water flows underground,
often for kilometres,
144
00:12:33,960 --> 00:12:38,960
before re-emerging again, sometimes
in a completely different valley.
145
00:12:42,120 --> 00:12:45,880
In these regions,
known as karst landscapes,
146
00:12:45,880 --> 00:12:49,000
salmon may have to travel
through many of these underground
147
00:12:49,000 --> 00:12:51,600
river systems to reach
their spawning grounds.
148
00:12:53,880 --> 00:12:57,720
The water that flows through this
special bedrock becomes very
149
00:12:57,720 --> 00:13:02,040
alkaline and carries nutrients
leached from the rocks.
150
00:13:02,040 --> 00:13:03,560
Ideal for salmon.
151
00:13:08,760 --> 00:13:12,560
This salmon creek is fairly small,
but it's full of fish.
152
00:13:14,560 --> 00:13:18,400
This could be a great spot to set up
and wait for the mother bear...
153
00:13:21,160 --> 00:13:23,840
..even though there are other
bears here already.
154
00:13:29,640 --> 00:13:33,320
This huge male is one of the
biggest black bears I've ever seen.
155
00:13:33,320 --> 00:13:35,720
He must be the dominant
bear on the creek,
156
00:13:35,720 --> 00:13:38,760
and could be a real problem
for a mother bear with cubs.
157
00:13:41,120 --> 00:13:44,160
There is at least a dozen bears
that use this creek,
158
00:13:44,160 --> 00:13:46,960
so I'm not sure our mother
will make an appearance.
159
00:13:50,360 --> 00:13:55,480
The salmon only have a few weeks
to spawn before they die,
160
00:13:55,480 --> 00:13:57,720
but many won't get the chance.
161
00:14:03,760 --> 00:14:06,920
Those white paws definitely
belong to a ghost bear...
162
00:14:10,840 --> 00:14:14,080
..and I'm relieved to see
that it's the mother bear.
163
00:14:14,080 --> 00:14:17,640
She has been lured from the forest
by the chance of a good meal.
164
00:14:22,560 --> 00:14:26,640
This will be the first salmon
she's tasted in almost a year.
165
00:14:26,640 --> 00:14:28,240
Hopefully, the first of many.
166
00:14:36,120 --> 00:14:38,640
But she's left her
cubs behind in the forest.
167
00:14:39,880 --> 00:14:43,440
Although they'll be alone, with all
the other bears on the creek,
168
00:14:43,440 --> 00:14:45,600
it's probably the right call.
169
00:14:50,240 --> 00:14:52,760
There are so many salmon here,
170
00:14:52,760 --> 00:14:55,480
it's almost like she doesn't
know where to start.
171
00:14:56,920 --> 00:14:58,960
PLAYFUL MUSIC
172
00:15:18,240 --> 00:15:21,320
And it looks like she's not going
to settle for just one.
173
00:15:30,000 --> 00:15:32,800
I've never seen a bear with one
salmon in its mouth
174
00:15:32,800 --> 00:15:35,160
trying to catch another.
175
00:15:35,160 --> 00:15:38,000
She's either really experienced,
or very hungry.
176
00:15:45,920 --> 00:15:49,360
Right now, it's still too risky
to bring the cubs to the salmon...
177
00:15:59,200 --> 00:16:03,560
..instead it looks like she's
taking the salmon to the cubs.
178
00:16:07,040 --> 00:16:10,200
It didn't take me long to learn
that the mother bear
179
00:16:10,200 --> 00:16:13,040
liked to eat her salmon beneath
a particular tree
180
00:16:13,040 --> 00:16:15,320
that the cubs were often in.
181
00:16:15,320 --> 00:16:18,960
So I was able to set up a remote
camera right there
182
00:16:18,960 --> 00:16:23,080
to observe what the cubs thought
of their first salmon.
183
00:16:23,080 --> 00:16:25,360
One cub was quick to the dinner
table,
184
00:16:25,360 --> 00:16:29,400
but the other was definitely
a little more cautious.
185
00:16:35,880 --> 00:16:38,840
And he seemed far more curious
about my camera,
186
00:16:38,840 --> 00:16:42,520
than about the fresh salmon his
mother brought him to eat.
187
00:16:56,440 --> 00:16:58,520
While the mother bear seems
188
00:16:58,520 --> 00:17:01,400
completely unconcerned by my camera,
189
00:17:01,400 --> 00:17:03,080
she has other worries.
190
00:17:03,080 --> 00:17:05,440
Keeping the cubs in the forest
191
00:17:05,440 --> 00:17:08,400
will really limit her fishing-time.
192
00:17:08,400 --> 00:17:12,440
Soon she is going to have to risk
bringing them to the creek.
193
00:17:16,480 --> 00:17:19,240
And she doesn't wait long.
194
00:17:19,240 --> 00:17:21,120
With no other bears around,
195
00:17:21,120 --> 00:17:22,800
she makes the move.
196
00:17:24,360 --> 00:17:26,840
This is a big moment in
the cubs' lives.
197
00:17:28,960 --> 00:17:30,920
She's got to be careful, though,
198
00:17:30,920 --> 00:17:33,360
another bear could turn up
at any moment.
199
00:17:41,720 --> 00:17:44,720
The cubs are a bit nervous being
out in the creek,
200
00:17:44,720 --> 00:17:48,560
and they know they have to stick
close to her wherever she goes.
201
00:18:08,080 --> 00:18:10,760
While there are still lots of salmon
around,
202
00:18:10,760 --> 00:18:13,560
the mother bear can be selective
with what she eats.
203
00:18:14,760 --> 00:18:17,360
She takes a bite of this salmon...
204
00:18:17,360 --> 00:18:19,240
and then drops it.
205
00:18:19,240 --> 00:18:22,520
She can probably tell from the taste
it's a male.
206
00:18:24,520 --> 00:18:28,640
Bears need to target the richest,
most nutritious food source.
207
00:18:28,640 --> 00:18:32,280
What she really wants to find
are female salmon...
208
00:18:34,320 --> 00:18:36,880
..and she'll go out of her way
to catch one.
209
00:18:40,000 --> 00:18:41,840
Female salmon are loaded
210
00:18:41,840 --> 00:18:45,840
with thousands of brightly coloured,
nutrient-rich eggs.
211
00:18:48,320 --> 00:18:50,880
This is the best part of the salmon,
212
00:18:50,880 --> 00:18:54,120
high in calories and fat...
213
00:18:54,120 --> 00:18:56,400
and she doesn't want
to leave any behind.
214
00:19:04,560 --> 00:19:07,000
The cubs, though,
still need to learn
215
00:19:07,000 --> 00:19:09,120
which are the best parts to eat.
216
00:19:15,960 --> 00:19:17,840
Though the cubs are still nursing,
217
00:19:17,840 --> 00:19:21,480
they need these protein-rich salmon
as much as their mum does.
218
00:19:25,200 --> 00:19:28,600
The whole family has to put on
as much weight as possible
219
00:19:28,600 --> 00:19:30,440
before winter hibernation.
220
00:19:37,360 --> 00:19:41,200
The mother bear is always alert
to potential dangers to her cubs.
221
00:19:43,160 --> 00:19:46,000
Surprisingly,
it's another ghost bear.
222
00:19:46,000 --> 00:19:47,880
This one looks like a large male.
223
00:19:50,800 --> 00:19:53,280
The cubs know that when another
bear is around,
224
00:19:53,280 --> 00:19:55,400
they have to get out of there.
225
00:19:55,400 --> 00:19:57,960
They retreat to the safety
of the trees.
226
00:20:01,880 --> 00:20:04,120
The mother bear is much
smaller than him,
227
00:20:04,120 --> 00:20:06,280
but she's still going
right after him.
228
00:20:08,360 --> 00:20:10,880
I'm not sure that's such
a good idea -
229
00:20:10,880 --> 00:20:13,200
he could certainly do some
damage to her.
230
00:20:14,720 --> 00:20:17,720
And he doesn't seem much
deterred by her approach.
231
00:20:33,520 --> 00:20:36,120
That's a risky move on her part.
232
00:20:36,120 --> 00:20:38,800
Any time two bears
physically interact like that,
233
00:20:38,800 --> 00:20:41,160
there's a good chance one of them
could be hurt.
234
00:20:41,160 --> 00:20:43,120
They're very powerful animals.
235
00:20:44,880 --> 00:20:47,960
I don't know her character
well enough yet to decide
236
00:20:47,960 --> 00:20:50,040
if she's foolhardy or brave.
237
00:20:51,400 --> 00:20:53,000
Only time will tell.
238
00:20:54,760 --> 00:20:57,840
But her cubs knew what to do in
this situation -
239
00:20:57,840 --> 00:21:02,160
they knew that their best defence
was to get up as high into a tree,
240
00:21:02,160 --> 00:21:05,800
as quickly as possible.
241
00:21:09,000 --> 00:21:12,240
Bear cubs always seem so at ease
in these big trees,
242
00:21:12,240 --> 00:21:14,120
so far off the ground.
243
00:21:21,120 --> 00:21:23,720
They'll use their teeth as well
as their claws
244
00:21:23,720 --> 00:21:26,120
to hang on and move around.
245
00:21:37,800 --> 00:21:41,040
The mother bear seems to have won
the day,
246
00:21:41,040 --> 00:21:44,680
but these encounters with other
bears will be stressful for her.
247
00:21:48,720 --> 00:21:53,280
She wisely decides to take her cubs
back into the safety of forest.
248
00:21:57,640 --> 00:21:59,720
With the arrival of the salmon,
249
00:21:59,720 --> 00:22:03,560
the mother bear may also have to
worry about the resident wolf packs.
250
00:22:06,040 --> 00:22:10,360
Wolves on this coast are known
to catch salmon in these streams.
251
00:22:15,880 --> 00:22:19,560
It's lucky for her the ocean
provides such a bounty
252
00:22:19,560 --> 00:22:22,200
that the wolves seem content
to spend their time
253
00:22:22,200 --> 00:22:24,240
patrolling the shoreline.
254
00:22:34,400 --> 00:22:38,320
And they find a dead sea lion
that has washed up onto shore.
255
00:22:44,280 --> 00:22:47,680
The whiter wolf is the old
grandmother of the pack.
256
00:22:47,680 --> 00:22:49,600
Her teeth aren't strong enough
257
00:22:49,600 --> 00:22:52,080
to chew through the tough,
rubbery hide,
258
00:22:52,080 --> 00:22:54,400
as this younger wolf is
starting to do.
259
00:23:08,080 --> 00:23:11,440
For now, the old wolf must scavenge
the beach for smaller prey.
260
00:23:14,320 --> 00:23:16,600
THEY HOWL
261
00:23:16,600 --> 00:23:18,920
Wolves use howls to communicate.
262
00:23:21,120 --> 00:23:25,560
When they find food they alert the
other pack members to the discovery.
263
00:23:32,480 --> 00:23:36,680
The abundance of food from the ocean
means that these sea wolves
264
00:23:36,680 --> 00:23:40,200
can survive on just
60 square kilometres,
265
00:23:40,200 --> 00:23:44,680
whereas wolves inland can range
well over 1,000.
266
00:23:47,640 --> 00:23:50,000
This is a real bonanza for them -
267
00:23:50,000 --> 00:23:52,640
many kilos of fat-rich meat -
268
00:23:52,640 --> 00:23:57,080
and it will feed the pack
for a week or more.
269
00:24:02,880 --> 00:24:07,440
Eventually, even the old grandmother
wolf gets her chance to feed.
270
00:24:09,880 --> 00:24:12,520
The younger pack members have peeled
back the hide
271
00:24:12,520 --> 00:24:15,720
and the heat from the sun
has softened the carcass
272
00:24:15,720 --> 00:24:17,640
so she is able to eat her fill.
273
00:24:20,200 --> 00:24:23,160
While the summer sun has helped
this old wolf get a meal,
274
00:24:23,160 --> 00:24:26,320
it brings tougher times for some
of the other residents
275
00:24:26,320 --> 00:24:28,200
of the Great Bear Rainforest.
276
00:24:30,760 --> 00:24:33,040
Water levels on the creek
are dropping,
277
00:24:33,040 --> 00:24:36,080
and it's getting harder for
the bears to catch salmon.
278
00:24:38,520 --> 00:24:41,840
The salmon can't make it up and over
the falls now...
279
00:24:43,400 --> 00:24:47,040
..so they hole up in the remaining
deepwater pools.
280
00:24:50,480 --> 00:24:52,560
The bears keep trying...
281
00:24:52,560 --> 00:24:55,680
but salmon are very deep difficult
to catch in deep water.
282
00:25:06,160 --> 00:25:09,240
Chelsea and I are going to set up
our underwater camera
283
00:25:09,240 --> 00:25:13,440
in one of the pools to get
a salmon's-eye view.
284
00:25:13,440 --> 00:25:18,040
We wanted to test a theory about why
ghost bears are so prevalent here.
285
00:25:19,960 --> 00:25:23,200
We want to find out if white bears
catch more fish than black ones.
286
00:25:24,320 --> 00:25:27,520
There's new research that indicates
they can catch 30% more salmon
287
00:25:27,520 --> 00:25:29,960
during the day than black bears,
288
00:25:29,960 --> 00:25:32,000
because their white fur
289
00:25:32,000 --> 00:25:33,760
is less visible against the sky.
290
00:25:33,760 --> 00:25:37,120
This would give them a distinct
survival advantage.
291
00:25:42,360 --> 00:25:46,560
Salmon have excellent vision -
surprisingly similar to humans.
292
00:25:48,400 --> 00:25:50,240
We need to place the camera
293
00:25:50,240 --> 00:25:53,600
so that it's just the right spot
to see the bears against the sky.
294
00:25:56,160 --> 00:25:59,240
My dad asks me to do my best
bear imitation!
295
00:26:06,000 --> 00:26:08,680
Once we are happy with the camera
replacement,
296
00:26:08,680 --> 00:26:10,280
we just have to wait.
297
00:26:12,360 --> 00:26:15,160
It's not long before a black
bear arrives.
298
00:26:18,840 --> 00:26:20,840
From the salmon's perspective,
299
00:26:20,840 --> 00:26:23,720
he seems to blend in very well
against the trees.
300
00:26:27,120 --> 00:26:29,080
He even makes a lucky catch.
301
00:26:34,360 --> 00:26:38,360
On this narrow creek, the forest
obscures most of the sky above...
302
00:26:40,160 --> 00:26:42,560
..then I see our mother bear
approaching.
303
00:26:45,240 --> 00:26:48,320
She seems to stand out even more
against the trees
304
00:26:48,320 --> 00:26:49,760
than the black bear.
305
00:26:54,000 --> 00:26:56,200
But she still makes
a successful catch.
306
00:27:02,360 --> 00:27:05,240
Later we pointed the camera
more towards the sky
307
00:27:05,240 --> 00:27:07,440
and she did seem better camouflaged.
308
00:27:08,720 --> 00:27:11,240
It wasn't a very scientific test,
309
00:27:11,240 --> 00:27:13,200
but I think a bear's fishing
ability
310
00:27:13,200 --> 00:27:15,560
is as much to do with its age
and experience,
311
00:27:15,560 --> 00:27:17,560
as it does with its fur-colour.
312
00:27:24,880 --> 00:27:27,360
The more time we get to spend around
this bear,
313
00:27:27,360 --> 00:27:29,960
the more we are learning about
her skills.
314
00:27:29,960 --> 00:27:34,640
So far, she's managed to catch lots
of fish and keep her cubs safe.
315
00:27:36,240 --> 00:27:39,440
But the busiest and most important
part of the salmon season
316
00:27:39,440 --> 00:27:41,120
is still to come.
317
00:27:46,000 --> 00:27:49,880
While the mother bear lives on
these islands year-round,
318
00:27:49,880 --> 00:27:53,720
there are other creatures
that only come for a visit.
319
00:28:09,360 --> 00:28:11,840
These are North Pacific
humpback whales...
320
00:28:13,400 --> 00:28:17,160
..and 25 years ago you rarely
saw them on this coast.
321
00:28:21,040 --> 00:28:25,480
Today, there are about 2,000 that
spend the summer on BC's coast.
322
00:28:29,520 --> 00:28:33,240
The humpbacks feed by lunging
sideways into the water...
323
00:28:34,760 --> 00:28:38,680
..gulping down millions of
tiny krill in massive mouthfuls.
324
00:28:46,800 --> 00:28:48,960
The humpbacks share their summer
feeding grounds
325
00:28:48,960 --> 00:28:50,960
with Steller sea lions.
326
00:28:50,960 --> 00:28:52,920
GURGLING, BARKING GROWLS
327
00:29:00,240 --> 00:29:01,760
The juvenile sea lions
328
00:29:01,760 --> 00:29:04,800
are very curious about
their giant neighbours.
329
00:29:08,160 --> 00:29:12,720
Filming at sea level, it wasn't
clear exactly what was going on.
330
00:29:12,720 --> 00:29:15,760
Were the sea lions trying to feed
around whales,
331
00:29:15,760 --> 00:29:17,760
or were they trying to play
with them?
332
00:29:17,760 --> 00:29:19,240
We just couldn't tell.
333
00:29:21,280 --> 00:29:25,160
By using our small remote-control
aerial camera,
334
00:29:25,160 --> 00:29:27,560
my son Logan was able to capture
335
00:29:27,560 --> 00:29:28,960
a bird's-eye view.
336
00:29:40,760 --> 00:29:43,760
With the footage from above,
we could see that the sea lions
337
00:29:43,760 --> 00:29:46,800
were taking turns swimming closer
and closer to the humpbacks -
338
00:29:46,800 --> 00:29:49,320
like dare-devilish teenagers.
339
00:29:52,080 --> 00:29:55,400
And we could see now that the
humpbacks were clearly not happy
340
00:29:55,400 --> 00:29:57,000
with the sea lions' antics.
341
00:29:58,720 --> 00:30:02,680
This tail side-swiping is a sign
of aggression in whales.
342
00:30:06,360 --> 00:30:09,520
For the sea lions,
it's a dangerous game -
343
00:30:09,520 --> 00:30:12,240
a smack from a humpback's tail
would be deadly.
344
00:30:17,960 --> 00:30:21,840
The humpbacks slap the water
with their pectoral fins and tails
345
00:30:21,840 --> 00:30:24,280
in an effort to drive off the pesky
sea lions.
346
00:30:33,880 --> 00:30:37,320
While the humpbacks have made
a remarkable recovery,
347
00:30:37,320 --> 00:30:41,000
on this part of the coast,
their future is far from secure.
348
00:30:44,520 --> 00:30:48,600
There are plans to ship oil and gas
in massive tankers
349
00:30:48,600 --> 00:30:51,800
right through the heart of
the Great Bear Rainforest.
350
00:30:53,240 --> 00:30:56,200
Humpbacks have no biosonar
capacities
351
00:30:56,200 --> 00:31:00,080
and are therefore very vulnerable
to collisions with large ships.
352
00:31:03,240 --> 00:31:05,080
The traffic in these waters
353
00:31:05,080 --> 00:31:08,440
is expected to climb more than
100-fold
354
00:31:08,440 --> 00:31:11,360
if the planned pipelines and tanker
depots get built.
355
00:31:15,000 --> 00:31:17,280
It's not just whales that may
be impacted...
356
00:31:19,040 --> 00:31:22,360
..these rich, coastal waters
provide foraging opportunities
357
00:31:22,360 --> 00:31:23,960
for lots of other wildlife.
358
00:31:25,120 --> 00:31:27,840
Sea birds like these gulls,
loons and guillemots
359
00:31:27,840 --> 00:31:31,440
are all here to take advantage of
the schools of young herring
360
00:31:31,440 --> 00:31:33,360
living in these inland waters.
361
00:31:36,760 --> 00:31:39,840
The guillemots are expert
underwater hunters.
362
00:31:41,160 --> 00:31:44,240
They can easily dive up
to 100 metres.
363
00:31:48,680 --> 00:31:52,000
Herring will avoid swimming
through bubbles.
364
00:31:52,000 --> 00:31:55,400
The guillemots take advantage
of this to corral the herring
365
00:31:55,400 --> 00:31:57,560
and drive them up to the water's
surface.
366
00:32:01,800 --> 00:32:05,320
The trails of bubbles are air
trapped in the guillemots' feathers
367
00:32:05,320 --> 00:32:08,160
and squeezed out by the
water pressure as they dive.
368
00:32:11,360 --> 00:32:15,400
The guillemots remain underwater
for several minutes as they herd
369
00:32:15,400 --> 00:32:18,720
the frenzied herring into bigger
and bigger bait balls.
370
00:32:23,680 --> 00:32:27,240
Forming a bait ball is the herrings'
last-ditch defence.
371
00:32:30,520 --> 00:32:33,400
With the guillemots pushing them
up from below,
372
00:32:33,400 --> 00:32:35,880
the herring are driven
to the surface
373
00:32:35,880 --> 00:32:38,360
where the gulls have been waiting
to attack.
374
00:32:44,440 --> 00:32:47,960
Many dive into the bait ball
to try and make a catch.
375
00:32:53,880 --> 00:32:55,960
But some try a different
technique...
376
00:32:58,160 --> 00:32:59,960
Piracy!
377
00:33:14,680 --> 00:33:18,720
These feeding frenzies don't
last long, though,
378
00:33:18,720 --> 00:33:22,400
the herring eventually escape diving
deep out of reach
379
00:33:22,400 --> 00:33:24,200
of these surface predators.
380
00:33:28,040 --> 00:33:30,120
Back on the salmon creek,
381
00:33:30,120 --> 00:33:33,760
the water is low and the mother bear
is spending more time
382
00:33:33,760 --> 00:33:37,160
out here with her cubs scavenging
salmon carcasses.
383
00:33:38,520 --> 00:33:40,120
Fishing is tough right now.
384
00:33:46,960 --> 00:33:50,360
What's nice to see is how
increasingly tolerant
385
00:33:50,360 --> 00:33:52,480
she's becoming of us.
386
00:33:52,480 --> 00:33:55,040
She just goes about her day
like we're not even here.
387
00:34:02,840 --> 00:34:05,480
This is because the people she has
met before
388
00:34:05,480 --> 00:34:07,960
have treated her well.
389
00:34:07,960 --> 00:34:10,800
We're collaborating with local
bear guide
390
00:34:10,800 --> 00:34:14,440
Marvin Robinson, a member
of the Gitga'at First Nation.
391
00:34:18,120 --> 00:34:19,680
He spent a lot of time
392
00:34:19,680 --> 00:34:22,720
among the white bears in his
traditional territory,
393
00:34:22,720 --> 00:34:25,480
protecting them and guiding
photographers and tourists
394
00:34:25,480 --> 00:34:27,040
to see them.
395
00:34:30,240 --> 00:34:33,440
He has treated the bears
with respect and tolerance.
396
00:34:39,640 --> 00:34:42,400
This has really helped us
establish a relationship
397
00:34:42,400 --> 00:34:43,840
with this mother bear.
398
00:34:45,120 --> 00:34:47,640
She is so comfortable
in our presence -
399
00:34:47,640 --> 00:34:50,320
she'll even take a nap
right in front of us.
400
00:34:54,000 --> 00:34:58,600
In fact, she's looking so relaxed
it's actually a little worrying.
401
00:34:58,600 --> 00:35:01,960
While she doesn't need to be
concerned with us,
402
00:35:01,960 --> 00:35:04,720
she still does need to watch out
for other bears.
403
00:35:06,240 --> 00:35:08,320
At least the cubs are up in a tree.
404
00:35:11,600 --> 00:35:14,400
If she wants to avoid a close
encounter with another bear,
405
00:35:14,400 --> 00:35:17,440
she needs to literally sleep
with one eye open.
406
00:35:31,160 --> 00:35:33,280
And this is what I was worried
about.
407
00:35:38,280 --> 00:35:40,840
This big male doesn't know
the mother bear
408
00:35:40,840 --> 00:35:43,000
is asleep on the other side
of the tree.
409
00:35:51,400 --> 00:35:54,120
His sudden appearance startles her.
410
00:35:54,120 --> 00:35:56,360
LOUD GROWLING
411
00:35:56,360 --> 00:35:58,840
She has no idea of his intentions.
412
00:36:05,640 --> 00:36:07,640
LOW GROWLING
413
00:36:11,360 --> 00:36:14,800
She is very upset
by how close he got
414
00:36:14,800 --> 00:36:16,960
and reacts with real aggression.
415
00:36:26,800 --> 00:36:29,640
GROWLING CONTINUES
416
00:36:38,800 --> 00:36:40,880
This is just the sort of encounter
417
00:36:40,880 --> 00:36:43,840
that most mother bears try to avoid.
418
00:36:48,320 --> 00:36:52,400
It was a dangerous situation for her
to get yourself into.
419
00:36:56,560 --> 00:36:59,560
She is lucky the big male
didn't fight back.
420
00:36:59,560 --> 00:37:01,720
He's so much bigger than her
421
00:37:01,720 --> 00:37:05,960
that one swipe of his paw could've
injured or even killed her.
422
00:37:10,200 --> 00:37:12,600
For bears at this time of year,
423
00:37:12,600 --> 00:37:14,360
the stakes are high.
424
00:37:14,360 --> 00:37:18,600
And the next morning brings a stark
reminder of just how high.
425
00:37:21,640 --> 00:37:23,760
It's a little male black bear.
426
00:37:24,840 --> 00:37:28,240
He was most likely killed in a fight
with another bear -
427
00:37:28,240 --> 00:37:29,840
possibly the big male.
428
00:37:32,640 --> 00:37:36,880
Competition for salmon can be
fierce and, occasionally, fatal.
429
00:37:41,360 --> 00:37:43,240
The presence of this dead bear
430
00:37:43,240 --> 00:37:45,680
appears to have really upset
the mother.
431
00:37:47,200 --> 00:37:48,880
She needs the salmon,
432
00:37:48,880 --> 00:37:52,720
but the risk to her cubs is too high
to stay out on the creek right now.
433
00:37:56,280 --> 00:38:00,080
Luckily, this stressful situation
is about to change.
434
00:38:05,040 --> 00:38:08,680
The autumn rains finally arrive
after a long, dry summer.
435
00:38:12,120 --> 00:38:16,080
This place is called the Great
Bear Rainforest for a reason -
436
00:38:16,080 --> 00:38:20,120
more than three metres of rain falls
on these forests every year.
437
00:38:21,400 --> 00:38:24,360
It is one of the wettest places
in the northern hemisphere.
438
00:38:31,640 --> 00:38:33,960
This huge influx of fresh water
439
00:38:33,960 --> 00:38:36,960
cascades off the rocky
mountain slopes
440
00:38:36,960 --> 00:38:41,080
filling the streams and creating
surging waterfalls.
441
00:38:51,480 --> 00:38:53,280
Rising water levels
442
00:38:53,280 --> 00:38:56,000
mean that the salmon that have been
trapped in shallow water,
443
00:38:56,000 --> 00:38:58,640
can now continue their migration
upstream.
444
00:39:03,040 --> 00:39:06,640
But the higher water means that
it can sometimes take 24 hours
445
00:39:06,640 --> 00:39:08,840
and dozens of attempts
446
00:39:08,840 --> 00:39:11,040
for them to leap a single waterfall.
447
00:39:21,520 --> 00:39:24,520
The salmons' efforts are made even
more challenging
448
00:39:24,520 --> 00:39:26,600
by the presence
of hungry black bears.
449
00:39:34,400 --> 00:39:36,640
These two bears are very skinny.
450
00:39:36,640 --> 00:39:39,000
They've both been drawn
to the falls
451
00:39:39,000 --> 00:39:42,200
in a desperate attempt to catch one
of the leaping salmon.
452
00:39:50,120 --> 00:39:53,160
But they have to be in exactly
the right position,
453
00:39:53,160 --> 00:39:54,760
just a little bit off the mark
454
00:39:54,760 --> 00:39:56,240
and they won't catch a thing.
455
00:39:58,880 --> 00:40:02,160
This bear knows he needs a better
position to fish,
456
00:40:02,160 --> 00:40:04,080
but there is a real danger -
457
00:40:04,080 --> 00:40:07,280
a fall into this surging water
could be fatal.
458
00:40:38,320 --> 00:40:41,000
Not only does he have to stand
in this fast water,
459
00:40:41,000 --> 00:40:45,000
but he has to be secure enough
to reach for leaping fish.
460
00:41:06,880 --> 00:41:08,960
The other bear needs to get closer,
461
00:41:08,960 --> 00:41:11,560
but there's no place for him
to stand.
462
00:41:22,880 --> 00:41:24,360
They are so close...
463
00:41:24,360 --> 00:41:26,120
And yet, just out of reach.
464
00:41:33,960 --> 00:41:37,040
The bear on the other side of
the fall looks on in vain...
465
00:41:37,040 --> 00:41:39,040
He is just too high above the water.
466
00:41:40,720 --> 00:41:44,720
But this bear's precarious
position finally pays off.
467
00:41:57,920 --> 00:41:59,880
With water levels up on the creek,
468
00:41:59,880 --> 00:42:02,360
the salmon are
able to push further upstream
469
00:42:02,360 --> 00:42:06,240
and the bears have more
opportunities to catch them.
470
00:42:12,000 --> 00:42:15,160
With higher water, the mother bear
has moved to the falls
471
00:42:15,160 --> 00:42:17,600
where the salmon are most active.
472
00:42:17,600 --> 00:42:21,120
But the big male has taken over
the best fishing spot.
473
00:42:23,640 --> 00:42:25,520
She needs to keep herself safe,
474
00:42:25,520 --> 00:42:28,560
but she also needs access
to salmon.
475
00:42:31,600 --> 00:42:34,120
She cautiously moves closer
to the big male.
476
00:42:36,320 --> 00:42:38,800
She's probably still a little
unsure of him
477
00:42:38,800 --> 00:42:40,560
after their last encounter.
478
00:42:46,200 --> 00:42:48,920
There's lots of salmon swimming
through the falls now,
479
00:42:48,920 --> 00:42:51,120
but with big male so close by,
480
00:42:51,120 --> 00:42:54,920
she can't really move around
as freely as she needs to.
481
00:43:18,960 --> 00:43:22,240
The big male has control
of the best fishing site.
482
00:43:22,240 --> 00:43:24,960
But due to the closeness
of the mother bear,
483
00:43:24,960 --> 00:43:27,920
he also seems to be losing some
of his focus.
484
00:43:27,920 --> 00:43:30,440
MALE BEAR GROWLS
485
00:43:32,040 --> 00:43:34,240
Then he manages to grab
another salmon.
486
00:43:36,440 --> 00:43:39,520
However, this one is a male,
and he lets it go.
487
00:43:41,320 --> 00:43:43,640
The mother bear is less fussy
right now,
488
00:43:43,640 --> 00:43:46,800
but she's unable to take advantage
of the opportunity.
489
00:43:49,200 --> 00:43:52,080
Neither bear is very happy
with the presence of the other.
490
00:43:55,440 --> 00:43:57,360
The mother bear decides to move in
491
00:43:57,360 --> 00:44:00,400
and take advantage of the scraps
the big guy's left behind.
492
00:44:18,520 --> 00:44:20,520
Something has to give.
493
00:44:20,520 --> 00:44:23,560
At this rate, neither bear
is going to be successful.
494
00:44:31,680 --> 00:44:35,400
The mother is getting more
confident...
495
00:44:35,400 --> 00:44:37,840
growling at the big male,
496
00:44:37,840 --> 00:44:40,400
letting him know she wants him
out of there.
497
00:44:44,000 --> 00:44:46,680
Finally, she builds up the nerve
to storm his position.
498
00:44:48,280 --> 00:44:50,960
GROWLING
499
00:44:55,680 --> 00:44:58,920
LOW, SUSTAINED GROWLING
500
00:45:02,360 --> 00:45:06,240
Even though she's much smaller
than him, she's not backing down.
501
00:45:06,240 --> 00:45:09,240
She wants access to the salmon
more than he does.
502
00:45:15,000 --> 00:45:18,000
The big male tries to intimidate
her with his much larger size...
503
00:45:20,680 --> 00:45:23,800
..but she holds her nerve -
refusing to leave.
504
00:45:30,040 --> 00:45:32,200
Finally, the big male's
had enough,
505
00:45:32,200 --> 00:45:34,600
and moves on to other
fishing grounds.
506
00:45:40,800 --> 00:45:43,720
Now the mother bear has the falls
all to herself.
507
00:45:49,200 --> 00:45:51,200
This has been a hard-won salmon,
508
00:45:51,200 --> 00:45:54,720
but I think there's going to be
lots more where this came from now.
509
00:45:57,600 --> 00:45:59,840
Watching her these past months
510
00:45:59,840 --> 00:46:03,000
I've really been impressed
by how well she's done
511
00:46:03,000 --> 00:46:05,120
for herself and her family.
512
00:46:05,120 --> 00:46:07,880
She's a committed mother, who will
do what it takes
513
00:46:07,880 --> 00:46:10,640
to provide for her cubs
and keep them safe.
514
00:46:12,120 --> 00:46:16,040
As winter approaches, they should be
in good shape for hibernation.
515
00:46:20,680 --> 00:46:23,920
But she still had one more surprise
in store for me.
516
00:46:26,360 --> 00:46:28,520
On the very last day of filming,
517
00:46:28,520 --> 00:46:32,360
she allows me to get the camera
close enough to her cubs
518
00:46:32,360 --> 00:46:35,680
to see the world through the eyes
of an individual bear.
519
00:46:40,760 --> 00:46:43,960
25 years ago, when Sue and I
first came here,
520
00:46:43,960 --> 00:46:47,760
we had never before been in a place
where the wildlife allowed us
521
00:46:47,760 --> 00:46:49,960
to get so immersed in their world.
522
00:47:00,160 --> 00:47:03,800
It's been such a privilege to be
able to come back here
523
00:47:03,800 --> 00:47:05,200
all these years later
524
00:47:05,200 --> 00:47:09,040
and have the opportunity to see even
closer into the world of bears.
525
00:47:13,320 --> 00:47:18,280
It's a testament to just how special
the Great Bear Rainforest is -
526
00:47:18,280 --> 00:47:20,680
this temperate rainforest right
next to
527
00:47:20,680 --> 00:47:22,840
the cold, rich North Pacific Ocean
528
00:47:22,840 --> 00:47:27,440
combine to make this a unique
environment full of life.
529
00:47:32,560 --> 00:47:34,800
And nowhere else on the planet
530
00:47:34,800 --> 00:47:37,440
can you find a family of bears
like this.
531
00:47:41,360 --> 00:47:44,400
With such a great role model
to follow,
532
00:47:44,400 --> 00:47:47,520
I don't think these cubs will have
any trouble
533
00:47:47,520 --> 00:47:51,920
eventually making their own way
on these islands they call home.
534
00:48:00,560 --> 00:48:02,400
As a wildlife film-maker
535
00:48:02,400 --> 00:48:05,880
I've had the opportunity to film
all around the world,
536
00:48:05,880 --> 00:48:09,880
but coming back here to the
Great Bear Rainforest with my family
537
00:48:09,880 --> 00:48:14,720
reminds me again what a unique
and extraordinary place this is.
538
00:48:16,840 --> 00:48:18,680
There's nowhere like it in the world
539
00:48:18,680 --> 00:48:21,720
and it needs to be celebrated
and protected.
540
00:48:23,640 --> 00:48:27,880
There is such richness and diversity
everywhere you look,
541
00:48:27,880 --> 00:48:30,160
but during our filming we discovered
542
00:48:30,160 --> 00:48:33,120
that it still had some amazing
secrets to reveal.
543
00:48:46,560 --> 00:48:49,920
The Great Bear Rainforest
on the west coast of Canada,
544
00:48:49,920 --> 00:48:52,920
is a huge, largely intact,
wilderness
545
00:48:52,920 --> 00:48:55,880
74,000 square kilometres in size.
546
00:48:57,760 --> 00:49:00,040
British Columbia contains
one fourth
547
00:49:00,040 --> 00:49:02,680
of all the temperate rainforests
left on Earth.
548
00:49:04,080 --> 00:49:06,800
It's a forested archipelago
of thousands of islands,
549
00:49:06,800 --> 00:49:08,880
fjords and inlets.
550
00:49:08,880 --> 00:49:10,880
What makes this place so unique
551
00:49:10,880 --> 00:49:14,440
is the fact that it's adjacent
to the rich North Pacific Ocean.
552
00:49:17,240 --> 00:49:20,600
The sea here supports
an abundance of life.
553
00:49:20,600 --> 00:49:23,640
Harbour seals spend all year
here feeding.
554
00:49:27,720 --> 00:49:29,480
Surf scoters...
555
00:49:31,120 --> 00:49:34,080
..and the aptly named
goldeneye ducks,
556
00:49:34,080 --> 00:49:36,360
travel here to feed
on the abundant fish.
557
00:49:43,560 --> 00:49:45,520
During our past visits
558
00:49:45,520 --> 00:49:48,160
we've always focused our filming
efforts on the land,
559
00:49:48,160 --> 00:49:51,400
but there's an incredibly rich
world beneath the surface.
560
00:49:53,920 --> 00:49:57,080
Kelp thrive in these cold
fast-moving waters.
561
00:49:57,080 --> 00:50:00,320
It's one of the fastest-growing
plants on Earth
562
00:50:00,320 --> 00:50:02,640
and can reach up to 30 metres
in height.
563
00:50:04,800 --> 00:50:08,080
This is the first time we've taken
our cameras underwater
564
00:50:08,080 --> 00:50:09,480
to film the kelp forests.
565
00:50:11,920 --> 00:50:14,120
And for the seals that lived here,
566
00:50:14,120 --> 00:50:17,880
they were just as curious of our
cameras as we were of them.
567
00:50:29,360 --> 00:50:33,440
Each kelp strand provides
a habitat for up to 200 species
568
00:50:33,440 --> 00:50:36,160
and tens of thousands of individual
creatures.
569
00:50:38,080 --> 00:50:40,080
When we first filmed here
25 years ago,
570
00:50:40,080 --> 00:50:43,760
there were no sea otters in
this part of the central coast.
571
00:50:43,760 --> 00:50:45,840
They were hunted to extinction
572
00:50:45,840 --> 00:50:48,480
all along British Columbia's coast.
573
00:50:48,480 --> 00:50:51,000
A small number were reintroduced
about 40 years ago
574
00:50:51,000 --> 00:50:53,040
and the richness of this environment
575
00:50:53,040 --> 00:50:56,640
has allowed the population to grow
to more than 5,000 today.
576
00:50:58,280 --> 00:51:00,640
They are re-colonising areas of
the coast
577
00:51:00,640 --> 00:51:03,320
that have not had sea otters
for 100 years.
578
00:51:03,320 --> 00:51:06,320
Another success story on this
coast
579
00:51:06,320 --> 00:51:09,160
has been the arrival of the Pacific
white-sided dolphin.
580
00:51:11,120 --> 00:51:14,440
These agile hunters can reach
speeds of up to 40km an hour.
581
00:51:16,360 --> 00:51:20,240
25 years ago, they were virtually
non-existent here.
582
00:51:20,240 --> 00:51:25,280
Now, about 20,000 are making these
inshore waters their home.
583
00:51:27,600 --> 00:51:29,640
The productivity of life
beneath the sea,
584
00:51:29,640 --> 00:51:32,640
is directly linked to
that of the forest above.
585
00:51:39,280 --> 00:51:42,440
Along the boundary between the sea
and the forest,
586
00:51:42,440 --> 00:51:45,120
sandhill cranes arrive
to spend the summer.
587
00:51:46,640 --> 00:51:49,440
CROAKING CALLS
588
00:51:49,440 --> 00:51:53,280
Pairs return from California
every year to breed
589
00:51:53,280 --> 00:51:56,880
and raise their young in this rich
forest environment.
590
00:51:56,880 --> 00:52:00,800
Their distinctive resonant cry
can carry up to 5km.
591
00:52:04,480 --> 00:52:08,080
These temperate forests harbour
a greater abundance of life
592
00:52:08,080 --> 00:52:10,480
than any other type of forest
on earth.
593
00:52:18,160 --> 00:52:20,320
A big part of the reason for this
594
00:52:20,320 --> 00:52:23,320
is due to what's
happening beneath the surface.
595
00:52:25,800 --> 00:52:28,360
It has to do with the way water
flows through,
596
00:52:28,360 --> 00:52:30,720
and even beneath, this forest.
597
00:52:39,080 --> 00:52:42,920
Many of the trees grow on
the permeable karst bedrock.
598
00:52:42,920 --> 00:52:44,760
Here the land is so soft
and fractured,
599
00:52:44,760 --> 00:52:46,680
that water flowing on the surface
600
00:52:46,680 --> 00:52:49,560
can suddenly disappear through
a hole in the ground.
601
00:52:51,920 --> 00:52:55,920
Down here there are many kilometres
of underground tunnels and chambers
602
00:52:55,920 --> 00:52:57,880
that the water flows through.
603
00:53:03,600 --> 00:53:07,280
It's this water that's the key
to the forest's success.
604
00:53:08,800 --> 00:53:11,520
Wherever this soluble karst bedrock
occurs,
605
00:53:11,520 --> 00:53:14,120
the trees grow to incredible
heights.
606
00:53:20,040 --> 00:53:23,640
The soil that develops on top
of this bedrock is well-drained,
607
00:53:23,640 --> 00:53:26,080
so the tree roots
don't get waterlogged.
608
00:53:28,120 --> 00:53:30,160
If the soil was removed
you could see
609
00:53:30,160 --> 00:53:33,160
the convoluted and cracked surface
of the bedrock
610
00:53:33,160 --> 00:53:35,080
that the rainwater flows through.
611
00:53:37,520 --> 00:53:40,760
This type of carbonate bedrock
is rich in nutrients.
612
00:53:42,080 --> 00:53:44,800
The eroding rainwater
carries these nutrients
613
00:53:44,800 --> 00:53:48,280
throughout the karst system
feeding the trees.
614
00:53:50,720 --> 00:53:53,880
And this makes them highly prized
by timber companies.
615
00:54:00,640 --> 00:54:03,280
Many of them, especially on
Vancouver Island,
616
00:54:03,280 --> 00:54:04,880
have already been logged.
617
00:54:12,040 --> 00:54:13,640
When the trees are cut down,
618
00:54:13,640 --> 00:54:15,760
the thin topsoil is vulnerable.
619
00:54:17,200 --> 00:54:18,800
If a fire occurs,
620
00:54:18,800 --> 00:54:21,960
this soil can be washed away
exposing the bare karst rock below.
621
00:54:23,440 --> 00:54:26,640
It could take hundreds of years
before a site recovers.
622
00:54:41,280 --> 00:54:44,160
I was keen to document life
beneath these forests.
623
00:54:44,160 --> 00:54:47,120
It's an important part
of the salmons' story.
624
00:54:49,080 --> 00:54:51,000
Filming in these underground rivers
625
00:54:51,000 --> 00:54:53,680
was something that had never been
attempted before,
626
00:54:53,680 --> 00:54:56,080
and I knew I needed help
to make it happen.
627
00:55:02,800 --> 00:55:05,040
Whoa!
628
00:55:05,040 --> 00:55:07,840
So, let's put it down there,
try to run it through the tunnel.
629
00:55:07,840 --> 00:55:10,640
If it doesn't fit, we'll leave it
back on the left, then assemble it
630
00:55:10,640 --> 00:55:12,920
and we can just form a little
line in.
631
00:55:14,920 --> 00:55:16,600
Travelling light today.
632
00:55:18,160 --> 00:55:20,920
'The first challenge was getting
hundreds of kilograms
633
00:55:20,920 --> 00:55:23,560
'of diving and underwater camera
gear into the caves.'
634
00:55:23,560 --> 00:55:26,560
Put it just below you, and then
we'll stage everything down to here.
635
00:55:32,240 --> 00:55:33,920
All this for one shot!
636
00:55:33,920 --> 00:55:36,720
THEY LAUGH
637
00:55:36,720 --> 00:55:39,680
'This was no place for anyone who
might suffer with claustrophobia!'
638
00:55:39,680 --> 00:55:41,920
Go ahead of me there.
639
00:55:44,320 --> 00:55:46,280
That's a bit of a squish, isn't it?
640
00:55:46,280 --> 00:55:48,680
It's quite exciting. OK. Yeah.
641
00:55:50,320 --> 00:55:52,000
'This was a first for all of us.
642
00:55:52,000 --> 00:55:54,880
'We were exploring a hidden world.'
643
00:55:54,880 --> 00:55:57,360
It's an amazing experience being
under here.
644
00:55:57,360 --> 00:56:00,640
These formations you just had
no idea existed here.
645
00:56:00,640 --> 00:56:03,400
'Once we got through the narrow
part of the cave,
646
00:56:03,400 --> 00:56:05,600
'it opened up into larger chambers.'
647
00:56:09,000 --> 00:56:12,680
During the wet season,
these tunnels can fill with water.
648
00:56:13,840 --> 00:56:16,720
But eventually, we arrived at this
underground lake,
649
00:56:16,720 --> 00:56:19,600
where we heard the salmon had been
seen in the past.
650
00:56:22,000 --> 00:56:25,280
This is one of the deepest
freshwater cave dives in Canada.
651
00:56:27,440 --> 00:56:30,320
The water is connected to the river
that flows above ground,
652
00:56:30,320 --> 00:56:34,280
so fish like this sculpin can move
in and out of the caves.
653
00:56:36,120 --> 00:56:39,080
For the dive team,
this is a cause for concern.
654
00:56:39,080 --> 00:56:41,560
I heard that the current can get up
to eight knots
655
00:56:41,560 --> 00:56:44,600
in certain places here. That's way
too strong to swim against.
656
00:56:49,000 --> 00:56:50,600
It looks OK, Alex?
657
00:56:50,600 --> 00:56:53,280
I think it looks good.
658
00:56:53,280 --> 00:56:56,960
'Once the guys decided the current
was safe, they were in the water,
659
00:56:56,960 --> 00:57:00,000
and their camera gear was lighting
up this dark underwater world.
660
00:57:04,000 --> 00:57:06,720
It didn't take long until
the salmon showed up,
661
00:57:06,720 --> 00:57:09,000
drawn to the sudden appearance
of light.
662
00:57:10,960 --> 00:57:13,440
This is the first time that
salmon have been filmed
663
00:57:13,440 --> 00:57:15,840
in these underground karst caves.
664
00:57:21,000 --> 00:57:23,960
While the salmon may have to
navigate these cave systems,
665
00:57:23,960 --> 00:57:27,640
the water here offers them
something extra.
666
00:57:27,640 --> 00:57:30,040
Thanks to the alkaline karst
bedrock,
667
00:57:30,040 --> 00:57:33,360
the water here is particularly rich
in nutrients and aquatic insects
668
00:57:33,360 --> 00:57:36,120
offering rich pickings
to hungry salmon.
669
00:57:38,600 --> 00:57:41,920
Research in Alaska shows that
salmon living in karst streams
670
00:57:41,920 --> 00:57:45,520
tend to be larger and more numerous
than in other rivers.
671
00:57:48,960 --> 00:57:51,800
It's become clear to me that
the karst landscapes
672
00:57:51,800 --> 00:57:53,520
of the Great Bear Rainforest
673
00:57:53,520 --> 00:57:56,600
are vitally important to the animals
that make their home here.
674
00:57:58,480 --> 00:58:00,720
But it's also a fragile landscape.
675
00:58:00,720 --> 00:58:03,800
Without stronger protection
for these karst regions,
676
00:58:03,800 --> 00:58:05,800
