BIRDSONG | 0:00:02 | 0:00:04 | |
Search and rescue teams are crossing Iceland's central plateau. | 0:00:14 | 0:00:18 | |
A few kilometres below them, a huge reservoir of molten magma | 0:00:21 | 0:00:25 | |
shakes the ground as it makes its way to the surface. | 0:00:25 | 0:00:28 | |
The question is not IF an eruption will take place, | 0:00:32 | 0:00:35 | |
but when...and where. | 0:00:35 | 0:00:37 | |
Icelanders have turned their unstable, cold, rugged island | 0:00:41 | 0:00:45 | |
into one of the most modern and culturally-rich nations on earth. | 0:00:45 | 0:00:48 | |
But they still keep one foot in the wild | 0:00:50 | 0:00:53 | |
and a very careful eye on the beast stirring beneath them. | 0:00:53 | 0:00:56 | |
Over what turns out to be an explosive year, | 0:00:59 | 0:01:02 | |
and through the eyes of wild foxes... | 0:01:02 | 0:01:04 | |
..an eider duck farmer... | 0:01:06 | 0:01:08 | |
..and Viking horsemen, | 0:01:11 | 0:01:12 | |
we'll see why everything on Iceland | 0:01:12 | 0:01:15 | |
remains uniquely connected to the land underfoot. | 0:01:15 | 0:01:18 | |
Under the eerie glow of the Northern Lights, | 0:01:33 | 0:01:36 | |
Iceland is in the iron grip of winter. | 0:01:36 | 0:01:39 | |
Lying close to the Arctic Circle, | 0:01:47 | 0:01:49 | |
with just a few hours of light a day, | 0:01:49 | 0:01:52 | |
it has endured months below zero. | 0:01:52 | 0:01:54 | |
At this time of year, it's hard to imagine Iceland's fiery origins, | 0:02:11 | 0:02:15 | |
but the island emerged as molten lava | 0:02:15 | 0:02:18 | |
from deep beneath the Atlantic Ocean. | 0:02:18 | 0:02:20 | |
It's one of the planet's newest pieces of land. | 0:02:22 | 0:02:25 | |
Everywhere are reminders of how little time it's had | 0:02:29 | 0:02:32 | |
to shed its raw, rocky character, | 0:02:32 | 0:02:34 | |
and how closely it's connected to the very centre of the earth. | 0:02:34 | 0:02:38 | |
Iceland is so new and so isolated in the North Atlantic | 0:02:48 | 0:02:52 | |
that, until relatively recently, | 0:02:52 | 0:02:54 | |
there were no land mammals here at all. | 0:02:54 | 0:02:57 | |
But during the last Ice Age, | 0:03:11 | 0:03:12 | |
when it was connected to Greenland by ice bridges and ice floes, | 0:03:12 | 0:03:17 | |
a very tenacious predator turned up. | 0:03:17 | 0:03:20 | |
The Arctic fox. | 0:03:26 | 0:03:28 | |
Iceland's first land mammal, | 0:03:31 | 0:03:33 | |
in its many colour variations, was here to stay. | 0:03:33 | 0:03:37 | |
But how it survived on Iceland without any of its regular prey, | 0:03:43 | 0:03:47 | |
like lemmings, has long fascinated scientist Ester Unnsteinsdottir. | 0:03:47 | 0:03:52 | |
'This is an Arctic species, it's adapted to the Arctic winter, | 0:03:54 | 0:03:58 | |
'which is really cold. | 0:03:58 | 0:04:00 | |
'And you can see it on the thick fur, | 0:04:00 | 0:04:03 | |
'it's the thickest fur in the universe, so very well insulating.' | 0:04:03 | 0:04:07 | |
It's actually better than a polar bear's | 0:04:08 | 0:04:11 | |
against the biting cold. | 0:04:11 | 0:04:12 | |
Enduring extreme weather is one thing - | 0:04:19 | 0:04:21 | |
its biggest challenge on Iceland is finding food. | 0:04:21 | 0:04:25 | |
They need to eat. | 0:04:27 | 0:04:28 | |
And if they don't have enough food in the wintertime, | 0:04:28 | 0:04:31 | |
especially before breeding, they don't manage to breed properly. | 0:04:31 | 0:04:37 | |
There is a remarkable lifeline. | 0:04:39 | 0:04:41 | |
An arm of the Gulf Stream helps to keep much of Iceland's | 0:04:42 | 0:04:46 | |
long, rocky coastline ice-free. | 0:04:46 | 0:04:49 | |
So even in winter, foxes can scavenge | 0:04:49 | 0:04:52 | |
the washed-up remains of fish, seabirds and sea mammals. | 0:04:52 | 0:04:56 | |
Only the toughest foxes hold on to a slice of good shoreline territory | 0:05:11 | 0:05:16 | |
and get the chance to breed. | 0:05:16 | 0:05:18 | |
But first, they have to find a mate. | 0:05:20 | 0:05:22 | |
A dark male appears to have won over a brown female. | 0:05:37 | 0:05:41 | |
A white male is desperate to mate with her, too. | 0:05:42 | 0:05:45 | |
And succeeds in grabbing her attention. | 0:05:51 | 0:05:54 | |
For a while, he seems to have outfoxed his rival. | 0:05:58 | 0:06:02 | |
But it doesn't end well for him. | 0:06:11 | 0:06:13 | |
The white male will have to try elsewhere. | 0:06:15 | 0:06:17 | |
Hopefully, this brown female, with the victor in tow, | 0:06:21 | 0:06:25 | |
has the strength she'll need to have a family. | 0:06:25 | 0:06:27 | |
For the weak or the inexperienced, winter is a punishing time. | 0:06:33 | 0:06:38 | |
Less than half of all foxes survive. | 0:06:39 | 0:06:42 | |
Sea mammals have an easier ride. | 0:06:54 | 0:06:57 | |
The ice-free waters offer | 0:06:57 | 0:06:58 | |
some of the best fishing in the North Atlantic... | 0:06:58 | 0:07:01 | |
..attracting not just seals, but whales and dolphins. | 0:07:03 | 0:07:07 | |
The fertile seas were a good reason for humans to settle here, too. | 0:07:09 | 0:07:13 | |
The first Vikings colonised Iceland just over a thousand years ago. | 0:07:17 | 0:07:21 | |
Down the generations, through fishing and farming, | 0:07:23 | 0:07:26 | |
they have carved out a unique way | 0:07:26 | 0:07:28 | |
of dealing with the many limits to life. | 0:07:28 | 0:07:31 | |
Most of Iceland's people, just over 300,000 of them, | 0:07:33 | 0:07:37 | |
are descended from the original settlers. | 0:07:37 | 0:07:40 | |
And many still work the land in tried and tested ways. | 0:07:40 | 0:07:43 | |
Even their livestock traces back to the animals | 0:07:46 | 0:07:48 | |
the Vikings brought with them. | 0:07:48 | 0:07:50 | |
Purest and most admired is the Icelandic horse. | 0:07:57 | 0:08:01 | |
It's smaller and much hardier than most other breeds. | 0:08:03 | 0:08:06 | |
Owners give them a little help towards winter's end, | 0:08:08 | 0:08:11 | |
but mostly, they tough out the cruellest of weather. | 0:08:11 | 0:08:14 | |
The best way to raise livestock here is to keep the animals semi-wild. | 0:08:17 | 0:08:21 | |
It gives them the character and spirit to survive | 0:08:22 | 0:08:25 | |
in this austere volcanic landscape. | 0:08:25 | 0:08:27 | |
But with little prime grazing land, | 0:08:36 | 0:08:39 | |
Icelanders could never rely on their livestock alone. | 0:08:39 | 0:08:42 | |
Long ago, the arrival of squadrons of swans, ducks and geese | 0:08:46 | 0:08:50 | |
would have offered relief from dwindling winter rations. | 0:08:50 | 0:08:53 | |
One species offered much more than a meal. | 0:08:58 | 0:09:00 | |
Eider ducks are among the millions of birds that are drawn to Iceland | 0:09:04 | 0:09:08 | |
from all around the North Atlantic. | 0:09:08 | 0:09:10 | |
These days, Thor Bjornsson makes an unusual living from them. | 0:09:14 | 0:09:19 | |
But he can't start work until the eiders have finished pairing up | 0:09:19 | 0:09:23 | |
and have come ashore. | 0:09:23 | 0:09:25 | |
He, and the birds, are waiting for spring. | 0:09:38 | 0:09:42 | |
Exposed all winter to brutal Atlantic storms, | 0:09:52 | 0:09:56 | |
Iceland has been blanketed by huge volumes of snow. | 0:09:56 | 0:10:00 | |
When that melts, it fills thousands of streams and rivers. | 0:10:10 | 0:10:14 | |
And cascades over some of Europe's | 0:10:18 | 0:10:20 | |
largest and most powerful waterfalls. | 0:10:20 | 0:10:22 | |
Iceland is so new and remote | 0:10:49 | 0:10:51 | |
that relatively few species have made it here. | 0:10:51 | 0:10:55 | |
Its hardy pioneers are always under pressure. | 0:11:00 | 0:11:03 | |
Even now, it's a race to make the most of longer, warmer days ahead. | 0:11:05 | 0:11:10 | |
After a winter of famine, | 0:11:16 | 0:11:18 | |
male ptarmigan are hungry to reach the buds, packed with proteins, | 0:11:18 | 0:11:22 | |
which are swelling at the top of willows and birches. | 0:11:22 | 0:11:25 | |
It's a precarious high-wire act | 0:11:30 | 0:11:32 | |
for a bird that spends the majority of its time on the ground. | 0:11:32 | 0:11:36 | |
Down on the coast, Thor is impatient | 0:11:45 | 0:11:47 | |
for the eiders to get on with mating. | 0:11:47 | 0:11:50 | |
Millions of other migrating and resident birds | 0:11:58 | 0:12:01 | |
are already nursing eggs, set to take advantage | 0:12:01 | 0:12:04 | |
of what will be a very short, but bountiful summer. | 0:12:04 | 0:12:08 | |
BIRDSONG | 0:12:14 | 0:12:15 | |
Eventually, the eiders return to the western islands of Breidafjordur, | 0:12:22 | 0:12:27 | |
finding the same nest scrapes | 0:12:27 | 0:12:28 | |
that their mothers and grandmothers used before them. | 0:12:28 | 0:12:32 | |
The mother duck cradles her eggs in a pillow of down | 0:12:36 | 0:12:40 | |
collected from her own breast feathers. | 0:12:40 | 0:12:42 | |
There is no other duck down like it. | 0:12:45 | 0:12:47 | |
It's this down that Thor wants to harvest, | 0:12:51 | 0:12:54 | |
but he'll need his extended family to help gather it. | 0:12:54 | 0:12:57 | |
Thor's farm consists of nearly 300 small islands. | 0:13:01 | 0:13:05 | |
And they'll have to deal with over 3,000 wild eider ducks. | 0:13:05 | 0:13:09 | |
It's going to be a busy few weeks. | 0:13:14 | 0:13:16 | |
Spring has finally reached Hornstrandir, | 0:13:22 | 0:13:25 | |
the craggy, lonely, north-western corner of Iceland. | 0:13:25 | 0:13:29 | |
After a severe winter, this female fox | 0:13:37 | 0:13:40 | |
is hanging around one of only two den sites. | 0:13:40 | 0:13:44 | |
The lack of food over the past few months will have taken its toll, | 0:13:46 | 0:13:51 | |
but now she has to step up a gear. | 0:13:51 | 0:13:53 | |
She's looking after not just herself... | 0:13:54 | 0:13:57 | |
..but six newborn cubs. | 0:14:08 | 0:14:10 | |
Her work is cut out. | 0:14:16 | 0:14:17 | |
She's a mum with a sky-high milk bill. | 0:14:17 | 0:14:20 | |
Just to keep up production, she's going to have to spend | 0:14:20 | 0:14:23 | |
the next weeks hunting fulltime. | 0:14:23 | 0:14:26 | |
Arctic foxes are feisty opportunists. | 0:14:42 | 0:14:45 | |
They may be small, but when livestock arrived on Iceland, | 0:14:47 | 0:14:50 | |
they soon worked out how to kill animals much larger than themselves. | 0:14:50 | 0:14:54 | |
In response, the early settlers began hunting foxes | 0:14:56 | 0:15:00 | |
to keep their numbers under control. | 0:15:00 | 0:15:02 | |
Today, foxes still take livestock | 0:15:04 | 0:15:07 | |
and the hunting quotas enshrined in law in the 13th century | 0:15:07 | 0:15:11 | |
are still in force. | 0:15:11 | 0:15:13 | |
On Iceland's marginal land, | 0:15:16 | 0:15:18 | |
the challenges facing both fox and farmer cannot be underestimated. | 0:15:18 | 0:15:23 | |
Making a living out here is tough. | 0:15:25 | 0:15:27 | |
For farmers like Halldor, horses are their pride and joy. | 0:15:30 | 0:15:34 | |
These days, Halldor and his son-in-law, Snorri, | 0:15:39 | 0:15:42 | |
mostly breed them for riding. | 0:15:42 | 0:15:44 | |
Horses are still better than 4x4s | 0:15:51 | 0:15:53 | |
on Iceland's rough tracks and mountain passes. | 0:15:53 | 0:15:56 | |
Just as sturdy and dependable | 0:15:56 | 0:15:59 | |
as when they were the backbone of Icelandic communities. | 0:15:59 | 0:16:02 | |
HE SPEAKS OWN LANGUAGE: | 0:16:06 | 0:16:09 | |
The finest horses became highly-regarded status symbols. | 0:16:52 | 0:16:55 | |
SNORRI IN ENGLISH: You had a lot of respect if you had the best horse. | 0:17:15 | 0:17:19 | |
Even if you were a poor farmer, | 0:17:19 | 0:17:20 | |
if you had the best horse, you had respect. | 0:17:20 | 0:17:23 | |
HALLDOR SPEAKS OWN LANGUAGE | 0:17:23 | 0:17:27 | |
SNORRI TRANSLATING: "Really important for the young guys to have a nice horse | 0:17:27 | 0:17:30 | |
"when they were looking for girls. | 0:17:30 | 0:17:32 | |
"When you came with good clothes, on a nice horse, | 0:17:32 | 0:17:36 | |
"you had a good chance." | 0:17:36 | 0:17:37 | |
Every spring, Halldor checks on his pregnant mares. | 0:17:47 | 0:17:51 | |
He hopes his favourite stallion will be the father. | 0:17:51 | 0:17:54 | |
The very best foals will be much admired at the end-of-year round-up, | 0:17:56 | 0:17:59 | |
but Halldor has no control over their arrival. | 0:17:59 | 0:18:02 | |
They give birth to their foals in secret. | 0:18:04 | 0:18:06 | |
Often after dark, and without help. | 0:18:06 | 0:18:09 | |
Halldor has to trust that his mares are robust enough to cope. | 0:18:14 | 0:18:18 | |
Over 3,000 eider ducks are now settled on eggs on Thor's islands. | 0:18:32 | 0:18:37 | |
He and his family carefully comb each rocky outcrop, | 0:18:45 | 0:18:49 | |
looking for nests. | 0:18:49 | 0:18:50 | |
Thor's unusual livelihood allows him | 0:18:53 | 0:18:55 | |
to spend time in the wildest parts of Iceland, | 0:18:55 | 0:18:58 | |
among the nature he loves so much. | 0:18:58 | 0:19:01 | |
'I started about 1970. | 0:19:01 | 0:19:04 | |
'And I was 14 years old then. | 0:19:05 | 0:19:08 | |
'I found it very, very nice to be with the birds, like this. | 0:19:08 | 0:19:13 | |
'Collecting down and all the wildlife around it.' | 0:19:13 | 0:19:17 | |
Thor carefully sets the eggs aside, removes the down, | 0:19:18 | 0:19:22 | |
and will re-cushion the eggs in soft, warm hay. | 0:19:22 | 0:19:26 | |
The female ducks can then return to their duties with no harm done. | 0:19:28 | 0:19:33 | |
His yield is limited by the number of birds that return each year. | 0:19:33 | 0:19:37 | |
Some years are better than others and... | 0:19:41 | 0:19:44 | |
..we get up to 55 kilos of eiderdown. | 0:19:45 | 0:19:49 | |
Normally, it's about 65 nests in one kilo of down. | 0:19:51 | 0:19:57 | |
Eiders have proved tricky to domesticate. | 0:19:59 | 0:20:02 | |
Their down can only be farmed from wild birds. | 0:20:02 | 0:20:05 | |
To increase overall numbers, | 0:20:05 | 0:20:08 | |
Thor collects and rears a few offspring | 0:20:08 | 0:20:11 | |
that may not otherwise survive. | 0:20:11 | 0:20:13 | |
'A lot of young ones, eider ducklings, die in many ways. | 0:20:13 | 0:20:18 | |
'Bad, er...weather, wet and windy. | 0:20:18 | 0:20:23 | |
'They cannot get enough food. | 0:20:23 | 0:20:25 | |
'So normally, they maybe raise up one duckling, | 0:20:25 | 0:20:28 | |
'two ducklings, something like that. | 0:20:28 | 0:20:30 | |
'We take one or two eggs from the nest, | 0:20:30 | 0:20:32 | |
'depends how many eggs are in the nest. | 0:20:32 | 0:20:35 | |
'When we started here, it was about something between 500 or 600 eiders | 0:20:35 | 0:20:40 | |
'nesting in the homeland area, but now it's more than 1,000, | 0:20:40 | 0:20:43 | |
'so they come back.' | 0:20:43 | 0:20:45 | |
While his eggs are incubating, Thor gets down to business. | 0:20:48 | 0:20:51 | |
Nearly three quarters of all eider duck down comes from Iceland, | 0:20:54 | 0:20:59 | |
and it's all gathered by hand. | 0:20:59 | 0:21:01 | |
Thor's family painstakingly pick the down clean | 0:21:02 | 0:21:06 | |
before it's bagged up for sale. | 0:21:06 | 0:21:08 | |
Most becomes a cosy filling for high-end duvets, quilts and jackets. | 0:21:08 | 0:21:13 | |
THEY SPEAK OWN LANGUAGE | 0:21:13 | 0:21:15 | |
Its secret may lie in the way the fibres flex and lock together, | 0:21:19 | 0:21:23 | |
creating thousands of minuscule air pockets. | 0:21:23 | 0:21:26 | |
It's such effective insulation | 0:21:27 | 0:21:29 | |
that it's been used to keep astronauts warm in space. | 0:21:29 | 0:21:32 | |
This is duck down that's flown to the moon and back. | 0:21:36 | 0:21:39 | |
CHIRPING | 0:21:41 | 0:21:43 | |
After a few days under a heat lamp, Thor's ducklings begin to hatch. | 0:21:46 | 0:21:51 | |
They grow quickly. | 0:21:51 | 0:21:53 | |
In the wild, eider ducklings can fledge after just a month. | 0:21:53 | 0:21:57 | |
CHIRPING | 0:21:57 | 0:21:59 | |
But under Thor's wing, | 0:22:03 | 0:22:04 | |
they stand a much better chance of making it to adulthood. | 0:22:04 | 0:22:08 | |
CHEEPING | 0:22:08 | 0:22:10 | |
For these first days, at least, | 0:22:24 | 0:22:26 | |
they only have eyes for their new duck dad. | 0:22:26 | 0:22:29 | |
They won't follow him around long-term, | 0:22:33 | 0:22:35 | |
but Thor will have to spend the rest of the summer | 0:22:35 | 0:22:38 | |
as a stay-at-home father, | 0:22:38 | 0:22:40 | |
teaching them skills they'll need to become wild birds. | 0:22:40 | 0:22:44 | |
The longest days of the year are approaching, | 0:22:48 | 0:22:51 | |
when the sun barely dips below the horizon. | 0:22:51 | 0:22:54 | |
The fullness of summer | 0:22:54 | 0:22:56 | |
is only really felt around the island's edges. | 0:22:56 | 0:22:59 | |
Hardly anything lives on the vast, ash-covered central plateau. | 0:23:06 | 0:23:10 | |
Its many volcanoes erupt too frequently and violently | 0:23:13 | 0:23:16 | |
to give life much chance. | 0:23:16 | 0:23:19 | |
It's like a sleeping giant that everyone's turned their back on, | 0:23:21 | 0:23:25 | |
but dares not forget is there. | 0:23:25 | 0:23:28 | |
Watching over the fox family, | 0:23:41 | 0:23:43 | |
Ester is spending more and more time on the Hornstrandir peninsula. | 0:23:43 | 0:23:47 | |
The cubs have been weaned, | 0:23:51 | 0:23:53 | |
but Mum's workload just gets bigger by the day. | 0:23:53 | 0:23:56 | |
Sibling rivalry can be lethal. | 0:23:59 | 0:24:02 | |
It's thought that each fight reinforces their rank in the family. | 0:24:04 | 0:24:08 | |
Dogged determination decides who gets most food | 0:24:10 | 0:24:13 | |
and who, ultimately, survives. | 0:24:13 | 0:24:16 | |
This mum seems to be made of particularly stern stuff | 0:24:37 | 0:24:40 | |
and is providing for all six of the cubs. | 0:24:40 | 0:24:43 | |
She's raising her family close to one of the most prolific | 0:24:54 | 0:24:57 | |
seabird colonies in Iceland. | 0:24:57 | 0:25:00 | |
There's lots of tempting food on offer. | 0:25:02 | 0:25:04 | |
The problem is that it's perched on sheer walls of rock. | 0:25:04 | 0:25:08 | |
If ever there was a high-stakes game, this mother is playing it. | 0:25:27 | 0:25:32 | |
One false step and she will plunge hundreds of metres | 0:25:43 | 0:25:47 | |
onto the rocks below. | 0:25:47 | 0:25:49 | |
Her cubs will effectively die with her. | 0:25:49 | 0:25:51 | |
SQUAWKING | 0:25:52 | 0:25:55 | |
She's found a kittiwake. | 0:26:18 | 0:26:20 | |
But with a growing family, | 0:26:23 | 0:26:24 | |
she will have to risk her life over and over again. | 0:26:24 | 0:26:28 | |
Today, she has the cliffs to herself, | 0:26:30 | 0:26:33 | |
but until the 1950s, foxes were in direct competition | 0:26:33 | 0:26:37 | |
with the people who eked out a living on this far-flung peninsula. | 0:26:37 | 0:26:41 | |
'It was very harsh, even for humans, you know. It was really tough. | 0:26:42 | 0:26:48 | |
'Bad winters and, er...not easy to survive. | 0:26:48 | 0:26:52 | |
'So, both for humans and foxes. | 0:26:52 | 0:26:56 | |
'And they were probably using the same resources, | 0:26:56 | 0:26:59 | |
'both space and food, | 0:26:59 | 0:27:01 | |
'so they were feeding on birds and eggs. | 0:27:01 | 0:27:03 | |
'And that's what people were also feeding on.' | 0:27:03 | 0:27:05 | |
On the remote island of Grimsey, | 0:27:08 | 0:27:10 | |
they still gather eggs from the massive summer colonies. | 0:27:10 | 0:27:13 | |
Its long coastline and towering cliffs of resistant volcanic rock | 0:27:17 | 0:27:21 | |
provide ledge space for thousands of kittiwakes and guillemots. | 0:27:21 | 0:27:25 | |
And burrows above for puffins. | 0:27:27 | 0:27:30 | |
BIRDSONG | 0:27:30 | 0:27:32 | |
Across Iceland, there is still the taste for seabird eggs. | 0:27:41 | 0:27:45 | |
A traditional and free-range alternative | 0:27:45 | 0:27:47 | |
to battery-farmed chicken eggs. | 0:27:47 | 0:27:49 | |
These days, the kit may be relatively modern, | 0:27:51 | 0:27:54 | |
but it still requires an old-fashioned head for heights. | 0:27:54 | 0:27:57 | |
Timing is crucial. | 0:28:11 | 0:28:14 | |
Eggs are scooped up right after laying. | 0:28:14 | 0:28:16 | |
The theory being that as soon as the birds realise | 0:28:16 | 0:28:19 | |
their egg has gone, they'll re-lay. | 0:28:19 | 0:28:21 | |
The collectors simply delay the hatch by a few days. | 0:28:23 | 0:28:26 | |
The length of cliff which each collector sweeps | 0:28:54 | 0:28:57 | |
is strictly controlled. | 0:28:57 | 0:28:59 | |
Today, these eggs are sold through supermarkets, | 0:29:04 | 0:29:07 | |
or traded for autumn berries from the mainland. | 0:29:07 | 0:29:10 | |
For many, foraging remains a part of everyday life, | 0:29:29 | 0:29:33 | |
tapping into the rich natural resources around them. | 0:29:33 | 0:29:36 | |
The most remarkable resource of all is the heat beneath their feet. | 0:29:45 | 0:29:49 | |
The island lies over the edge of two continental plates | 0:29:55 | 0:29:58 | |
that are pulling away from each other. | 0:29:58 | 0:30:01 | |
Iceland is being stretched apart in the middle. | 0:30:01 | 0:30:04 | |
It's the easiest place for boiling molten rock | 0:30:06 | 0:30:09 | |
to rise towards the surface. | 0:30:09 | 0:30:11 | |
This readily heats groundwater, | 0:30:14 | 0:30:17 | |
which, day to day, can be rather useful. | 0:30:17 | 0:30:19 | |
Long ago, Icelanders discovered how it could slow-cook | 0:30:20 | 0:30:24 | |
one of their most celebrated foods, lava bread. | 0:30:24 | 0:30:27 | |
Every household has its own secret recipe for roobrau, | 0:30:30 | 0:30:34 | |
but each loaf will be baked in much the same way. | 0:30:34 | 0:30:37 | |
Once the dough is bucketed up, it will be placed in a hot spring - | 0:30:41 | 0:30:45 | |
nearly every rural community has one - | 0:30:45 | 0:30:48 | |
and then left for 24 hours. | 0:30:48 | 0:30:51 | |
The immense geothermal power on offer | 0:31:03 | 0:31:06 | |
has transformed the lives of all Icelanders. | 0:31:06 | 0:31:09 | |
They live just south of the Arctic Circle. | 0:31:10 | 0:31:13 | |
Yet, modern, ground-heated greenhouses | 0:31:13 | 0:31:15 | |
allow them to ripen vegetables and fruits | 0:31:15 | 0:31:18 | |
that wouldn't otherwise stand a chance of growing here. | 0:31:18 | 0:31:21 | |
They've created a sustainable bubble | 0:31:28 | 0:31:30 | |
in which plants and their pollinators | 0:31:30 | 0:31:32 | |
defy the limits of growing on raw, northern rock. | 0:31:32 | 0:31:36 | |
But along with their daily bread, Icelanders are fed updates | 0:31:40 | 0:31:44 | |
on the many earthquakes that occur on the island. | 0:31:44 | 0:31:47 | |
It's as routine as the weather forecast. | 0:31:47 | 0:31:50 | |
And this year, it seems, more important than ever. | 0:31:50 | 0:31:53 | |
In late May, a swarm of 200 earthquakes | 0:31:56 | 0:32:00 | |
register under the Bardarbunga volcano in central Iceland. | 0:32:00 | 0:32:04 | |
It lies under Europe's largest glacier, Vatnajokull. | 0:32:05 | 0:32:09 | |
And eruptions in the past have caused catastrophic floods. | 0:32:09 | 0:32:13 | |
There's no evidence as yet that magma is on its way to the surface, | 0:32:19 | 0:32:24 | |
but pilots overflying the area | 0:32:24 | 0:32:26 | |
are asked to keep an eye on any changes to the ground below them. | 0:32:26 | 0:32:30 | |
On this extraordinary island, | 0:32:37 | 0:32:39 | |
ordinary life simply goes on. | 0:32:39 | 0:32:41 | |
There have been over a dozen eruptions | 0:32:44 | 0:32:46 | |
in Halldor's lifetime alone. | 0:32:46 | 0:32:48 | |
Right now, he has more immediate concerns. | 0:32:48 | 0:32:51 | |
One of his mares has just given birth. | 0:32:58 | 0:33:01 | |
Like many creatures that evolved on open grassland, | 0:33:03 | 0:33:06 | |
the foal's instinct is to get on its feet as quickly as possible. | 0:33:06 | 0:33:10 | |
It seems healthy. | 0:33:39 | 0:33:40 | |
The new foals will stay close to their mothers | 0:33:55 | 0:33:58 | |
for most of their first year. | 0:33:58 | 0:34:00 | |
But it may be the last Halldor sees of them for a long while. | 0:34:04 | 0:34:07 | |
Soon, all his horses will move up the valley and into the mountains. | 0:34:12 | 0:34:17 | |
It will give these lower pastures a break. | 0:34:17 | 0:34:20 | |
But the move is also important to encourage the foals to run free. | 0:34:22 | 0:34:26 | |
If they're to survive their first winter, | 0:34:27 | 0:34:30 | |
they need to become resilient. | 0:34:30 | 0:34:32 | |
Horses from all the farms around here | 0:34:39 | 0:34:41 | |
are allowed to return to their roots. | 0:34:41 | 0:34:44 | |
Just like the ancestral wild horse of the Eurasian Steppes, | 0:34:44 | 0:34:48 | |
they'll roam in large herds | 0:34:48 | 0:34:50 | |
and won't see their owners | 0:34:50 | 0:34:52 | |
for many months. | 0:34:52 | 0:34:54 | |
You want to keep this wildness a little bit in the horses. | 0:34:54 | 0:34:58 | |
And this is the best place to do that. | 0:34:58 | 0:35:00 | |
And it's also really important that young horses go there, foals, | 0:35:00 | 0:35:05 | |
to learn this as quickly as possible. | 0:35:05 | 0:35:08 | |
This strengthens their mind a lot to do this. | 0:35:08 | 0:35:13 | |
Because you never know in Iceland, if... Just... | 0:35:13 | 0:35:17 | |
If it gets lost on the mountains, | 0:35:17 | 0:35:20 | |
they know how to help themselves. | 0:35:20 | 0:35:23 | |
I think also for the growing of the horses and the young horses, | 0:35:23 | 0:35:28 | |
it's, like, it grows much better and stronger on the mountains. | 0:35:28 | 0:35:33 | |
The Skagafjordur region prides itself | 0:35:36 | 0:35:38 | |
on producing the very best Icelandic horses. | 0:35:38 | 0:35:41 | |
Strict rules control the breed. | 0:35:44 | 0:35:47 | |
A horse sold abroad is never allowed to return, | 0:35:49 | 0:35:52 | |
having lost the magic mix of wildness and trainability. | 0:35:52 | 0:35:56 | |
This is the trait Halldor's foals must develop | 0:35:58 | 0:36:01 | |
if they are to do him proud at the end-of-year round-up. | 0:36:01 | 0:36:04 | |
The short summer is pressing on. | 0:36:20 | 0:36:23 | |
Wild eider ducks are already leading their young broods out on the water. | 0:36:23 | 0:36:27 | |
The eider is a diving duck | 0:36:36 | 0:36:38 | |
that spends the whole winter living at sea. | 0:36:38 | 0:36:41 | |
It's vital they become powerful swimmers. | 0:36:41 | 0:36:43 | |
Thor's ducklings, too, | 0:36:49 | 0:36:51 | |
must begin learning how to face the trials ahead. | 0:36:51 | 0:36:54 | |
Younger members of the family lead the way. | 0:36:59 | 0:37:02 | |
They get very quickly very big and strong. | 0:37:06 | 0:37:10 | |
And we bring them to the sea every day, or sometimes twice a day, | 0:37:10 | 0:37:14 | |
to feed in the sea and swim a little bit. | 0:37:14 | 0:37:17 | |
Here, they'll build up their muscles and sharpen their instincts. | 0:37:20 | 0:37:23 | |
They're still vulnerable to the cold | 0:37:25 | 0:37:27 | |
and to ravenous black-backed gulls, | 0:37:27 | 0:37:29 | |
so the children must guide and protect them. | 0:37:29 | 0:37:32 | |
First days, we have to look very well after them | 0:37:35 | 0:37:38 | |
because they want to go away. | 0:37:38 | 0:37:40 | |
So we try to gather them and so they don't swim away. | 0:37:40 | 0:37:44 | |
This wilful streak is good. | 0:37:46 | 0:37:49 | |
It means they haven't been tamed. | 0:37:49 | 0:37:51 | |
All in all, it's a fun way for the kids to connect with nature. | 0:38:07 | 0:38:10 | |
And the smallest member of the family | 0:38:20 | 0:38:23 | |
gets to talk down to someone else. | 0:38:23 | 0:38:25 | |
It's home-time. | 0:38:48 | 0:38:50 | |
The ducklings are gently herded and counted back in. | 0:38:50 | 0:38:55 | |
Where they'll fluff themselves back up | 0:38:55 | 0:38:57 | |
in readiness for the next stage of their training. | 0:38:57 | 0:39:00 | |
For now, it's job done. | 0:39:07 | 0:39:09 | |
BIRDSONG | 0:39:14 | 0:39:16 | |
In Hornstrandir, the Atlantic Ocean is slowly gnawing | 0:39:16 | 0:39:20 | |
at what remains of a very ancient and immense lava flow. | 0:39:20 | 0:39:24 | |
On its unforgiving edge, the mother fox has defied the odds. | 0:39:29 | 0:39:33 | |
All six of her cubs are still alive. | 0:39:41 | 0:39:45 | |
Although life is a challenge, they currently stand | 0:39:45 | 0:39:47 | |
a better chance in Iceland than elsewhere in the Arctic. | 0:39:47 | 0:39:51 | |
'There's very few Arctic foxes left in Scandinavia. | 0:39:54 | 0:39:59 | |
'And they have been endangered for many, many years. | 0:39:59 | 0:40:03 | |
'But they're facing troubles that we are not facing here in Iceland.' | 0:40:03 | 0:40:08 | |
Ester believes the big problem for Arctic foxes in Scandinavia | 0:40:08 | 0:40:13 | |
is the northward march of the red fox, due to climate change. | 0:40:13 | 0:40:16 | |
As it moves into Arctic fox territory, | 0:40:18 | 0:40:21 | |
the red fox takes over their den sites, | 0:40:21 | 0:40:23 | |
competes for food and even kills adults and young. | 0:40:23 | 0:40:27 | |
The Arctic foxes on Iceland remain out of reach. | 0:40:31 | 0:40:36 | |
The island is an important stronghold for them. | 0:40:36 | 0:40:38 | |
Mum's job is nearly done. | 0:40:41 | 0:40:43 | |
In the next few weeks, the cubs will leave home. | 0:40:45 | 0:40:48 | |
Hunger may force them into taking livestock, | 0:40:56 | 0:40:58 | |
where they risk being shot. | 0:40:58 | 0:41:00 | |
The odds are that not all of these cubs will survive | 0:41:12 | 0:41:15 | |
the coming winter, or go on to breed. | 0:41:15 | 0:41:18 | |
But the Arctic fox has an almost heroic ability | 0:41:20 | 0:41:23 | |
to turn hardship into opportunity. | 0:41:23 | 0:41:26 | |
This mum's given them the best possible start in life. | 0:41:29 | 0:41:32 | |
This far north, the limits to life | 0:41:50 | 0:41:53 | |
for animals and humans, are very stark. | 0:41:53 | 0:41:56 | |
So Icelanders have never been shy of taking from nature. | 0:41:57 | 0:42:00 | |
Traditionally, they've harvested everything from seabirds to whales, | 0:42:03 | 0:42:07 | |
fish to seals, some of which they still take today. | 0:42:07 | 0:42:11 | |
But it's clear that if you live on an island, | 0:42:15 | 0:42:17 | |
especially one so remote and northerly, | 0:42:17 | 0:42:20 | |
you cannot take more than you need. | 0:42:20 | 0:42:22 | |
Ever since the Vikings first landed, | 0:42:28 | 0:42:30 | |
fishing the rich offshore waters | 0:42:30 | 0:42:32 | |
have been fundamental to the country's economy. | 0:42:32 | 0:42:35 | |
In the 1970s, Iceland even used gunboats | 0:42:36 | 0:42:39 | |
to defend a 200-mile fishing limit around their coast. | 0:42:39 | 0:42:43 | |
Today, with careful management, | 0:42:47 | 0:42:49 | |
their fisheries are some of the most sustainable in the world. | 0:42:49 | 0:42:52 | |
Their long-term thinking has helped other countries, too. | 0:43:01 | 0:43:04 | |
Icelandic rivers are important spawning grounds | 0:43:07 | 0:43:11 | |
for the Atlantic salmon. | 0:43:11 | 0:43:13 | |
But in the 1980s, salmon started to decline, | 0:43:16 | 0:43:20 | |
due mainly to overfishing | 0:43:20 | 0:43:22 | |
by commercial operations on the high seas. | 0:43:22 | 0:43:24 | |
By raising funds to buy out the netting operations, | 0:43:29 | 0:43:32 | |
effectively paying them not to fish, | 0:43:32 | 0:43:35 | |
millions of salmon were given a chance | 0:43:35 | 0:43:38 | |
to return to rivers, from Norway to North America. | 0:43:38 | 0:43:41 | |
The problem is far from over. | 0:43:46 | 0:43:48 | |
Striking a balance between harvesting and protecting | 0:43:48 | 0:43:51 | |
is an ongoing effort, | 0:43:51 | 0:43:53 | |
but Icelanders manage it in their own unique way. | 0:43:53 | 0:43:56 | |
It's a country where hunting and gathering | 0:43:58 | 0:44:00 | |
sit side by side with modern life. | 0:44:00 | 0:44:03 | |
A nation with a dynamic economy, built around Reykjavik, | 0:44:10 | 0:44:13 | |
the most northerly capital city in the world. | 0:44:13 | 0:44:16 | |
Cheap, clean, renewable power warms homes, | 0:44:18 | 0:44:21 | |
keeps the lights on and provides mains' hot water. | 0:44:21 | 0:44:24 | |
Even city pavements have underfloor heating. | 0:44:26 | 0:44:29 | |
Reykjavik's Opera House celebrates music and drama | 0:44:31 | 0:44:34 | |
inspired by the original Icelandic sagas. | 0:44:34 | 0:44:37 | |
But Icelanders are necessarily rooted in reality. | 0:44:38 | 0:44:42 | |
They can never forget they're living over a huge | 0:44:45 | 0:44:48 | |
and widening tear in the earth's crust. | 0:44:48 | 0:44:51 | |
And as summer draws to a close, | 0:44:53 | 0:44:55 | |
the giant reservoir of molten rock under them is beginning to stir. | 0:44:55 | 0:45:00 | |
Back on the Breidafjordur islands, wild eider offspring | 0:45:07 | 0:45:11 | |
are learning what to eat by watching their parents. | 0:45:11 | 0:45:14 | |
It's Thor's job to introduce his ducklings to the kind of food | 0:45:31 | 0:45:35 | |
that will keep them going out on the open water. | 0:45:35 | 0:45:37 | |
When they grow up, they'll be diving mainly for molluscs, | 0:45:40 | 0:45:43 | |
which they eat, shell and all. | 0:45:43 | 0:45:46 | |
Tiny crustaceans, stirred up from the shoreline, | 0:45:46 | 0:45:50 | |
are good starter foods. | 0:45:50 | 0:45:51 | |
In the end, Thor, as a surrogate duck dad, | 0:45:58 | 0:46:01 | |
can only give them a helping hand. | 0:46:01 | 0:46:03 | |
Little by little, they spread their wings, | 0:46:10 | 0:46:13 | |
foraging a little further from home, | 0:46:13 | 0:46:15 | |
becoming a little wilder every day. | 0:46:15 | 0:46:18 | |
But they swim then between here, close to the island | 0:46:21 | 0:46:25 | |
and go on their own trips feeding, | 0:46:25 | 0:46:28 | |
but they always come home in the evening. | 0:46:28 | 0:46:31 | |
So they find something in this ocean to eat, | 0:46:31 | 0:46:35 | |
so it make them a good start in their new life in the world. | 0:46:35 | 0:46:40 | |
Eventually, Thor leaves them on their own. | 0:46:46 | 0:46:48 | |
His nurturing work is done. | 0:46:50 | 0:46:52 | |
Nature will take over from here. | 0:46:54 | 0:46:56 | |
But Thor hopes their homing instinct | 0:47:00 | 0:47:02 | |
will bring them back to his islands next year. | 0:47:02 | 0:47:05 | |
In the high pastures, ripening blueberries | 0:47:17 | 0:47:20 | |
and the turning leaves mark the slide to autumn. | 0:47:20 | 0:47:24 | |
Even though the first snows are dusting the mountains, | 0:47:29 | 0:47:32 | |
it's a time eagerly awaited by farmers | 0:47:32 | 0:47:35 | |
in the northern area of Skagafjordur, | 0:47:35 | 0:47:37 | |
for it also heralds the event of their social calendar, | 0:47:37 | 0:47:42 | |
the annual round-up. | 0:47:42 | 0:47:43 | |
The horses might die up here in winter blizzards, | 0:48:21 | 0:48:24 | |
so farmers join forces to gather up the different herds | 0:48:24 | 0:48:28 | |
and drive them all down the valley. | 0:48:28 | 0:48:30 | |
For this year's foals, | 0:48:33 | 0:48:34 | |
it's a complete surprise to be near humans again | 0:48:34 | 0:48:37 | |
and it goes against the grain. | 0:48:37 | 0:48:39 | |
But this independent spirit | 0:49:02 | 0:49:04 | |
is exactly what Halldor and Snorri want. | 0:49:04 | 0:49:07 | |
It's what the Vikings saw in the ancestors of these horses | 0:49:07 | 0:49:10 | |
when they traded them from Mongolia | 0:49:10 | 0:49:13 | |
and brought them to Iceland over 1,000 years ago. | 0:49:13 | 0:49:16 | |
This is horse-trading nature's way. | 0:49:26 | 0:49:30 | |
THEY NEIGH | 0:49:45 | 0:49:46 | |
Somehow, each farmer must separate their own horses from the crowd. | 0:49:54 | 0:49:58 | |
But they're judging everyone else's at the same time. | 0:50:00 | 0:50:02 | |
No horse is broken in until it's at least four years old, | 0:50:11 | 0:50:14 | |
so most of them have a mind of their own. | 0:50:14 | 0:50:17 | |
But this is what they love about them. | 0:50:17 | 0:50:20 | |
It's been the only way to raise horses | 0:50:23 | 0:50:25 | |
in Iceland's harsh environment. | 0:50:25 | 0:50:27 | |
Their return from the mountains, though, always brings deep relief. | 0:50:32 | 0:50:36 | |
When all is done, Halldor and Snorri | 0:51:13 | 0:51:16 | |
will lead the horses back to the farm, | 0:51:16 | 0:51:18 | |
as generations have done before them. | 0:51:18 | 0:51:21 | |
The land under their feet demands respect. | 0:52:05 | 0:52:08 | |
And in this, of all years. | 0:52:09 | 0:52:11 | |
High in the central plateau, | 0:52:14 | 0:52:16 | |
the Bardarbunga volcano has sprung into life. | 0:52:16 | 0:52:19 | |
Over a thousand earthquakes in a single day | 0:52:20 | 0:52:22 | |
suggest a huge volume of molten rock trying to reach the surface. | 0:52:22 | 0:52:28 | |
But where? | 0:52:28 | 0:52:29 | |
Fearing massive floods | 0:52:30 | 0:52:32 | |
should the eruption melt the Vatnajokull glacier, | 0:52:32 | 0:52:36 | |
search and rescue teams evacuate a vast area. | 0:52:36 | 0:52:39 | |
Hour by hour, scientists track the earth tremors | 0:52:41 | 0:52:45 | |
that mark the movement of the magma. | 0:52:45 | 0:52:47 | |
The column of hot rock is snaking northwards. | 0:52:47 | 0:52:50 | |
Eventually, it breaks through a fissure in the plains, | 0:53:01 | 0:53:05 | |
just beyond the edge of the glacier. | 0:53:05 | 0:53:07 | |
It's big. Probably the biggest lava eruption | 0:53:08 | 0:53:13 | |
that we have seen for 30 years or so, I would guess. | 0:53:13 | 0:53:17 | |
As it turns out, nothing like it | 0:53:19 | 0:53:22 | |
has been seen on Iceland for over 200 years. | 0:53:22 | 0:53:25 | |
The fissure is about 400 metres long, | 0:53:37 | 0:53:40 | |
but lava pours out at nearly 300 cubic metres a second, | 0:53:40 | 0:53:45 | |
like a cut that won't stop bleeding. | 0:53:45 | 0:53:47 | |
Underneath Iceland, the Eurasian plate is pulling eastwards | 0:53:49 | 0:53:53 | |
and the North American plate is pulling westwards. | 0:53:53 | 0:53:58 | |
Until this eruption, the island has been spreading apart | 0:53:58 | 0:54:01 | |
at two centimetres a year. | 0:54:01 | 0:54:04 | |
Here, it's opening up ten times faster. | 0:54:04 | 0:54:07 | |
The lava is a ferocious 1,200-degrees centigrade. | 0:54:10 | 0:54:16 | |
It would melt even cast iron | 0:54:16 | 0:54:18 | |
and incinerate a human being in seconds. | 0:54:18 | 0:54:21 | |
This is as close as we get to seeing into the centre of the earth. | 0:54:23 | 0:54:27 | |
The ground shakes as the fissure splits open even further, | 0:54:49 | 0:54:53 | |
creating a rift that's 1.5 kilometres long. | 0:54:53 | 0:54:57 | |
Pumped by pressure that's been building for centuries, | 0:55:11 | 0:55:14 | |
superheated gas and water causes tonnes of lava | 0:55:14 | 0:55:18 | |
to fountain up to 100 metres into the air all along its length. | 0:55:18 | 0:55:22 | |
These are the same monumental forces | 0:55:24 | 0:55:27 | |
that created Iceland in the first place. | 0:55:27 | 0:55:29 | |
Over the next six months, | 0:56:33 | 0:56:34 | |
the lava flow covers over 85 square kilometres. | 0:56:34 | 0:56:38 | |
85,000 tonnes of poisonous sulphur dioxide | 0:56:45 | 0:56:49 | |
is released into the atmosphere every day. | 0:56:49 | 0:56:52 | |
In 1783, an eruption on Iceland | 0:56:58 | 0:57:02 | |
threw up so much ash and sulphur dioxide | 0:57:02 | 0:57:05 | |
that it's thought to have caused famine on a global scale | 0:57:05 | 0:57:08 | |
and the deaths of six-million people worldwide. | 0:57:08 | 0:57:12 | |
Miraculously, this fissure allows the colossal pressure | 0:57:15 | 0:57:18 | |
under Bardarbunga to be released slowly. | 0:57:18 | 0:57:22 | |
Had it gone off just a few kilometres away, | 0:57:22 | 0:57:25 | |
explosively, under the Vatnajokull glacier, | 0:57:25 | 0:57:28 | |
the picture would be very different. | 0:57:28 | 0:57:30 | |
It's the ultimate reminder that the lives of all Icelanders | 0:57:37 | 0:57:41 | |
depend on the raw forces beneath them. | 0:57:41 | 0:57:43 | |
A wild life, | 0:57:51 | 0:57:53 | |
uniquely connected to nature, it may be, | 0:57:53 | 0:57:55 | |
but the remarkable people and animals that live here | 0:57:55 | 0:57:59 | |
have learned how to work with the land, | 0:57:59 | 0:58:02 | |
rather than fight against it. | 0:58:02 | 0:58:04 | |
They've taken all of Iceland's opportunities | 0:58:06 | 0:58:09 | |
and challenges in their stride. | 0:58:09 | 0:58:11 | |
