South Wales - an industrial landscape. | 0:00:24 | 0:00:27 | |
But step away and there's beauty. | 0:00:27 | 0:00:29 | |
Open countryside, vast beaches and sand dunes, tall and imposing. | 0:00:29 | 0:00:36 | |
These dunes are so important | 0:00:36 | 0:00:37 | |
that they've been designated a Site of Special Scientific Interest. | 0:00:37 | 0:00:41 | |
But all is not well here, | 0:00:41 | 0:00:42 | |
because they're turning from free-flowing sand | 0:00:42 | 0:00:45 | |
to giant, solid grass hills | 0:00:45 | 0:00:48 | |
and I'm going to be finding out | 0:00:48 | 0:00:50 | |
why they're moving sand on a massive scale | 0:00:50 | 0:00:53 | |
to restore life to these dunes. | 0:00:53 | 0:00:55 | |
I'm inland from Matt, unearthing a tale of deception. | 0:01:00 | 0:01:04 | |
68 years ago, the biggest escape | 0:01:04 | 0:01:06 | |
by German prisoners of war from the United Kingdom took place right here. | 0:01:06 | 0:01:11 | |
70 prisoners tunnelled their way to freedom from this hut | 0:01:11 | 0:01:14 | |
and now, with the help of a digger and 3D technology, | 0:01:14 | 0:01:18 | |
we're going to discover exactly how they did it. | 0:01:18 | 0:01:21 | |
Meanwhile, Tom's hot on the trail of our fastest-growing source of energy. | 0:01:25 | 0:01:30 | |
You might like to burn a log or two | 0:01:30 | 0:01:32 | |
to give your living room a bit of sparkle | 0:01:32 | 0:01:34 | |
but Government and industry are rebranding wood as biomass | 0:01:34 | 0:01:38 | |
and think it could be a good way to generate | 0:01:38 | 0:01:42 | |
lots of electricity to power our lives. | 0:01:42 | 0:01:45 | |
Environmental triumph, or a disaster? I'll be investigating. | 0:01:45 | 0:01:49 | |
And Adam's finding out how we satisfy the nation's sweet tooth. | 0:01:50 | 0:01:54 | |
This is a root crop called sugar beet | 0:01:56 | 0:01:59 | |
and there's around 20,000 tonnes of it down there, | 0:01:59 | 0:02:04 | |
and it's used to make this stuff - granulated sugar. | 0:02:04 | 0:02:08 | |
I'll be following this crop from the harvest in the field | 0:02:08 | 0:02:11 | |
right through to sugar here in the factory. | 0:02:11 | 0:02:13 | |
The vast beaches of South Wales - | 0:02:25 | 0:02:28 | |
glistening waters, lined by golden sands. | 0:02:28 | 0:02:30 | |
Endless rugged dunes hug this land. | 0:02:32 | 0:02:34 | |
We're on a stretch of the coast between Swansea and Bridgend | 0:02:36 | 0:02:40 | |
starting here at Kenfig sands. | 0:02:40 | 0:02:42 | |
This may look like a typical seaside scene, | 0:02:43 | 0:02:46 | |
apart from the hefty steelworks puffing away over there, | 0:02:46 | 0:02:48 | |
but there's a lot more to this place than a bucket-and-spade holiday. | 0:02:48 | 0:02:52 | |
It is, in fact, one of the most important nature conservation sites | 0:02:52 | 0:02:55 | |
in Britain, and that is all to do with these sand dunes. | 0:02:55 | 0:02:59 | |
But the ones here in Kenfig are disappearing. | 0:02:59 | 0:03:02 | |
Over the years, | 0:03:08 | 0:03:09 | |
they've changed from the exotic Lawrence of Arabia-style | 0:03:09 | 0:03:12 | |
dusty hues of yellow to a mass of matted green. | 0:03:12 | 0:03:15 | |
I can't imagine a caravan of camels sauntering across these! | 0:03:17 | 0:03:20 | |
Being overgrown with all this vegetation | 0:03:21 | 0:03:24 | |
is the beginning of the end for these sand dunes | 0:03:24 | 0:03:27 | |
and for what makes this place so special. | 0:03:27 | 0:03:29 | |
With one of the biggest issues being that some rare plants and insects | 0:03:29 | 0:03:33 | |
are being driven to the brink of extinction. | 0:03:33 | 0:03:36 | |
To find out more, I'm meeting botanist Andy Byfield. | 0:03:36 | 0:03:40 | |
So, Andy, what's going on here then? | 0:03:42 | 0:03:44 | |
Think about sand dunes from your childhood. | 0:03:44 | 0:03:47 | |
You remember these windy, open places, lots of bare sand, | 0:03:47 | 0:03:51 | |
lots of sand pricking the backs of your legs and that sort of thing. | 0:03:51 | 0:03:55 | |
Those days are over. | 0:03:55 | 0:03:56 | |
What's happened over the last 20 or 30 years | 0:03:56 | 0:03:59 | |
is that the sand dunes have become vegetated. | 0:03:59 | 0:04:03 | |
Wind the clock back 50 years, | 0:04:03 | 0:04:05 | |
nearly half this place was just open, bare sand. | 0:04:05 | 0:04:09 | |
The situation today is that the vast bulk of it | 0:04:09 | 0:04:12 | |
is covered with thick, choking grasslands. | 0:04:12 | 0:04:14 | |
Is it purely the problem that the grass has locked itself into the sand? | 0:04:14 | 0:04:17 | |
Yes, it starts open but if you don't do anything to it, | 0:04:17 | 0:04:21 | |
the vegetation starts to grow up and eventually, | 0:04:21 | 0:04:23 | |
you get a few brambles coming in, a few brushes and ultimately, | 0:04:23 | 0:04:27 | |
if the process continues, you get to a stage where willows | 0:04:27 | 0:04:30 | |
and birch trees and that sort of thing come in. | 0:04:30 | 0:04:33 | |
You go from a beautiful, romantic open habitat, | 0:04:33 | 0:04:36 | |
a very wild, windy, mobile habitat to a very stabilised woodland. | 0:04:36 | 0:04:41 | |
And it's this stabilisation that's now threatening | 0:04:43 | 0:04:46 | |
the future of many rare plant species. | 0:04:46 | 0:04:48 | |
These things have evolved to grow on bare sand. | 0:04:50 | 0:04:54 | |
They've just spent millennia doing that. | 0:04:54 | 0:04:56 | |
Things like this one - it's a classic dune plant. | 0:04:56 | 0:04:59 | |
You can see two things here, actually. | 0:04:59 | 0:05:01 | |
There, you can see the variegated horsetail and there, | 0:05:01 | 0:05:05 | |
a beautiful plant, that's the brick red form of the early marsh orchid. | 0:05:05 | 0:05:09 | |
That's one thing. What else have we got here? | 0:05:09 | 0:05:11 | |
That is the marsh helleborine. | 0:05:11 | 0:05:13 | |
The Americans call it "the chatterbox orchid" | 0:05:13 | 0:05:15 | |
because its lower lip sort of shakes as though it's sort of freezing. | 0:05:15 | 0:05:19 | |
The numbers of these must have drastically reduced? | 0:05:19 | 0:05:22 | |
Yeah, the classic one is the fen orchid, | 0:05:22 | 0:05:24 | |
which is this beautiful lime green orchid. | 0:05:24 | 0:05:27 | |
We know really only a few decades ago | 0:05:27 | 0:05:29 | |
-there were as many as eight or nine sites with the orchid. -Yeah. | 0:05:29 | 0:05:32 | |
And it's gone from eight or nine sites down to just one site | 0:05:32 | 0:05:36 | |
-in just a few decades. -Goodness me! | 0:05:36 | 0:05:38 | |
I can't think of any orchid in Britain | 0:05:38 | 0:05:40 | |
that's declining more rapidly than that. | 0:05:40 | 0:05:42 | |
But here at Kenfig, the fight back is under way | 0:05:50 | 0:05:52 | |
with a rather radical new project. | 0:05:52 | 0:05:55 | |
The diggers are in, | 0:05:55 | 0:05:56 | |
removing the top layer of grass to loosen up the sand. | 0:05:56 | 0:05:59 | |
Once the grass is removed, | 0:05:59 | 0:06:00 | |
the wind will blow freely through the dunes again, | 0:06:00 | 0:06:03 | |
distributing the seeds of the precious plants | 0:06:03 | 0:06:06 | |
that we're rapidly losing. | 0:06:06 | 0:06:07 | |
Reserve manager David Carrington is the man with the battle plan. | 0:06:07 | 0:06:11 | |
We like to call it rejuvenation. | 0:06:12 | 0:06:14 | |
We're sort of breathing life into | 0:06:14 | 0:06:17 | |
a dune system that's become over stable. | 0:06:17 | 0:06:20 | |
The diggers are giving mother nature a hand | 0:06:20 | 0:06:22 | |
but those of us out enjoying the coast can play our part too. | 0:06:22 | 0:06:26 | |
There are areas of the reserve where the only bare sand we've got | 0:06:26 | 0:06:29 | |
is because of people's footfall. | 0:06:29 | 0:06:31 | |
There is that tendency, where you've got some precious habitat, | 0:06:31 | 0:06:34 | |
to say, "Oh, keep off it, don't touch." | 0:06:34 | 0:06:37 | |
But it's not necessarily the right approach on a sand dune site, | 0:06:37 | 0:06:40 | |
where movement of sand and erosion and recovery, you know, | 0:06:40 | 0:06:45 | |
is critical really to the special plants and insects. | 0:06:45 | 0:06:48 | |
How often will you have to keep digging here? | 0:06:48 | 0:06:50 | |
It does depend a bit on the funding. | 0:06:50 | 0:06:52 | |
The Welsh Government have provided funding for this project. | 0:06:52 | 0:06:55 | |
Ideally, every few years, | 0:06:55 | 0:06:56 | |
there'll be another area that's done and we'll create another site. | 0:06:56 | 0:07:01 | |
-Lee, is it all right to come up and have a chat? -Yeah, no problem. | 0:07:10 | 0:07:13 | |
I love driving diggers and I love building sand castles. | 0:07:13 | 0:07:16 | |
-Is it all right if I have a little seat? -Yeah. | 0:07:16 | 0:07:18 | |
Right, you're going to have to tell me where to dig and what to do. | 0:07:18 | 0:07:22 | |
So, you're just taking off this corner here, are you? | 0:07:22 | 0:07:25 | |
-Just taking that off, yeah. So if you get this down here now. -Yep... | 0:07:25 | 0:07:28 | |
-There we are, we should be good to go. -And then we lift her up... | 0:07:28 | 0:07:31 | |
Well, while I'm having fun on the sand dunes here in Wales, | 0:07:39 | 0:07:42 | |
Tom is finding out why burning wood is coming back into fashion. | 0:07:42 | 0:07:45 | |
Britain by night - a land shining with man-made light. | 0:07:52 | 0:07:58 | |
It's a power that's created increasingly by renewable energy. | 0:07:58 | 0:08:02 | |
And our small island is leading the way | 0:08:02 | 0:08:05 | |
in the latest green fuel to find favour. | 0:08:05 | 0:08:08 | |
That revolutionary renewable isn't wind, solar or wave, | 0:08:09 | 0:08:13 | |
but mankind's original fuel - wood - | 0:08:13 | 0:08:17 | |
or, as it's being called today, biomass. | 0:08:17 | 0:08:20 | |
Some think it can make Britain and the world a cleaner, greener place. | 0:08:20 | 0:08:24 | |
Others fear it's an environmental time bomb. | 0:08:24 | 0:08:27 | |
'To find out the truth, I'm going to follow two very different projects | 0:08:29 | 0:08:32 | |
'from start to finish.' | 0:08:32 | 0:08:34 | |
-Hi, Tom, good to meet you. -Very nice to meet you. | 0:08:34 | 0:08:37 | |
'My journey begins here, in the woods of Richmond Park.' | 0:08:37 | 0:08:41 | |
I did actually feel the ground shake there! | 0:08:48 | 0:08:50 | |
'Biomass refers to any plant life harvested for energy, | 0:08:50 | 0:08:54 | |
'but most currently comes from wood. | 0:08:54 | 0:08:58 | |
'So here, they're felling trees to use as fuel, | 0:08:58 | 0:09:00 | |
'feeding a local business converting to biomass.' | 0:09:00 | 0:09:03 | |
So, I see there's great excitement, great drama in doing this, | 0:09:10 | 0:09:13 | |
but in what way is it actually good for the environment? | 0:09:13 | 0:09:16 | |
Well, for this species of tree in particular, | 0:09:16 | 0:09:18 | |
these have a detrimental effect on the wildlife in the park. | 0:09:18 | 0:09:22 | |
It's a non-native tree, the Turkey oak. | 0:09:22 | 0:09:24 | |
By removing them, it'll bring the light levels back into the woodland, | 0:09:24 | 0:09:27 | |
we retain all the native trees, | 0:09:27 | 0:09:29 | |
they then flourish, they put on girth, | 0:09:29 | 0:09:31 | |
put on a larger crown, more leaves, more insects, | 0:09:31 | 0:09:34 | |
which has a knock-on effect for the birds and the bats. | 0:09:34 | 0:09:37 | |
So as far as you're concerned, the demand for wood to burn - | 0:09:37 | 0:09:41 | |
biomass as it's called - is actually helping you to manage the place? | 0:09:41 | 0:09:45 | |
Absolutely. I'm sure that biomass boilers are fitted in | 0:09:45 | 0:09:47 | |
because of the climate change agenda | 0:09:47 | 0:09:49 | |
and that's looking at global conservation. | 0:09:49 | 0:09:52 | |
If you put the markets into your local woodlands | 0:09:52 | 0:09:54 | |
you're actually doing local conservation as well. | 0:09:54 | 0:09:56 | |
The use of biomass has shot up by 17% in the UK | 0:09:58 | 0:10:03 | |
in the last year alone - a rise driven by the race | 0:10:03 | 0:10:07 | |
to reduce our greenhouse gas emissions by 2020. | 0:10:07 | 0:10:10 | |
But in what way can burning wood be considered green? | 0:10:12 | 0:10:15 | |
Well, wood really has two destinies. | 0:10:15 | 0:10:17 | |
If it falls down and begins to rot like this, | 0:10:17 | 0:10:21 | |
that emits carbon dioxide into the atmosphere. | 0:10:21 | 0:10:24 | |
The same happens when you burn it. | 0:10:24 | 0:10:26 | |
The difference is that if that process of combustion is used | 0:10:26 | 0:10:30 | |
to create energy, you've avoided using a fossil fuel to do that | 0:10:30 | 0:10:34 | |
and also, whether it rots or whether it's burnt, | 0:10:34 | 0:10:37 | |
that carbon dioxide is reabsorbed when you plant more trees. | 0:10:37 | 0:10:42 | |
It seems like everyone's a winner. Or maybe not... | 0:10:45 | 0:10:49 | |
Some critics are concerned that the figures don't add up. | 0:10:49 | 0:10:53 | |
They say we're actually creating a carbon debt | 0:10:53 | 0:10:56 | |
by quickly releasing carbon into the atmosphere | 0:10:56 | 0:11:00 | |
that new trees will take decades to reabsorb. | 0:11:00 | 0:11:03 | |
All this at a time | 0:11:03 | 0:11:05 | |
when we should be urgently reducing our greenhouse gas emissions. | 0:11:05 | 0:11:08 | |
What most people do agree on is that small-scale schemes like this one | 0:11:10 | 0:11:14 | |
do make environmental sense. | 0:11:14 | 0:11:17 | |
What's proving more controversial are big projects | 0:11:17 | 0:11:20 | |
that are driving a huge surge in the demand for biomass | 0:11:20 | 0:11:24 | |
and that's where I'm heading next. | 0:11:24 | 0:11:26 | |
On his farm near Wetherby, | 0:11:29 | 0:11:31 | |
Gareth Gaunt is part of a cooperative | 0:11:31 | 0:11:33 | |
being paid by Britain's largest power station | 0:11:33 | 0:11:36 | |
to grow 2,000 acres of willow to feed their biomass machine. | 0:11:36 | 0:11:41 | |
I'm meeting him on site, a few miles from his own farm, | 0:11:41 | 0:11:44 | |
where the willow's only three years old | 0:11:44 | 0:11:47 | |
but already ripe for harvesting as an energy crop. | 0:11:47 | 0:11:50 | |
-Is this one ready to go, ready to be cut? -Yes, this one is ready. | 0:11:50 | 0:11:53 | |
-This one is three years old and ready to go. -With the big beast here? | 0:11:53 | 0:11:57 | |
With the big beast here. Here's your... | 0:11:57 | 0:11:59 | |
-It looks like one hell of a toy! Hi, are you in control of this? -I am. | 0:11:59 | 0:12:03 | |
-This is Dean. Tom. -All right, Tom? | 0:12:03 | 0:12:05 | |
-Can I have a go? -Yeah, if you want. | 0:12:05 | 0:12:09 | |
You'd better give me a lesson, then. | 0:12:09 | 0:12:12 | |
Throttle up to the top. | 0:12:12 | 0:12:14 | |
-Right up to the rabbit, here? -Yeah. | 0:12:14 | 0:12:16 | |
This operation is certainly impressive | 0:12:19 | 0:12:22 | |
but it's also taking up some land | 0:12:22 | 0:12:23 | |
that was previously used for growing wheat and barley - | 0:12:23 | 0:12:27 | |
staple food crops - and this is another concern for critics. | 0:12:27 | 0:12:30 | |
Yeah, that isn't bad at all. Let's call it a day there. | 0:12:32 | 0:12:35 | |
Yeah, well done. | 0:12:35 | 0:12:37 | |
How do the figures compare between growing willow like this | 0:12:38 | 0:12:41 | |
and growing an arable crop? | 0:12:41 | 0:12:43 | |
Well I'm making about £400 a hectare now on willow. | 0:12:43 | 0:12:46 | |
Previously, when I was growing wheat, some years I was losing money. | 0:12:46 | 0:12:52 | |
Doesn't it mean, though, that you would be producing less food in this country? | 0:12:52 | 0:12:57 | |
It is, whether you like it or not, a sort of food versus fuel battle. | 0:12:57 | 0:13:00 | |
It is, but I think if farmers really examined | 0:13:00 | 0:13:03 | |
some of the poorer-quality fields that they're not making a profit on, | 0:13:03 | 0:13:09 | |
I think they could improve the yields on some of the better quality land. | 0:13:09 | 0:13:13 | |
I don't think we need lose any land mass for growing food. | 0:13:13 | 0:13:19 | |
So the country can produce a bit more fuel | 0:13:19 | 0:13:21 | |
-and the same amount of food going forward? -Absolutely, absolutely. | 0:13:21 | 0:13:24 | |
How you grow biomass is where the debate starts over its green credentials | 0:13:27 | 0:13:31 | |
but the scale on which we use it is where things really heat up. | 0:13:31 | 0:13:35 | |
Some critics are claiming that big business biomass | 0:13:36 | 0:13:40 | |
could become dirtier than the fossil fuels it's set to replace | 0:13:40 | 0:13:43 | |
and that's what I'll be investigating later. | 0:13:43 | 0:13:46 | |
Whilst Matt's exploring the sand dunes | 0:13:55 | 0:13:57 | |
along this part of the South Wales coast, | 0:13:57 | 0:13:59 | |
I'm heading inland just a little to the home of a | 0:13:59 | 0:14:02 | |
man who made the most of the area's natural resources | 0:14:02 | 0:14:05 | |
and created an industrial landscape. | 0:14:05 | 0:14:08 | |
Christopher Rice Mansel Talbot, | 0:14:08 | 0:14:11 | |
known to his friends as Kit Talbot, | 0:14:11 | 0:14:14 | |
was an extremely wealthy and very savvy Victorian estate owner | 0:14:14 | 0:14:18 | |
who boosted his fortune by exploiting the minerals, the coal and the iron, | 0:14:18 | 0:14:24 | |
that lay beneath his land. | 0:14:24 | 0:14:26 | |
He built ironworks and dockyards over there by the coast | 0:14:26 | 0:14:30 | |
and the place was named in his honour - Port Talbot. | 0:14:30 | 0:14:34 | |
He lived here, on his estate covering 850 acres of woodlands, scrub, | 0:14:34 | 0:14:40 | |
grassland and streams - a vivid contrast to Talbot's industrial port. | 0:14:40 | 0:14:45 | |
I'm meeting local historian, John Adams, | 0:14:45 | 0:14:47 | |
to hear more about this gentleman wheeler-dealer who, | 0:14:47 | 0:14:50 | |
from his mansion, owned all he surveyed. | 0:14:50 | 0:14:53 | |
Well, quite a place that Kit built for himself! | 0:14:53 | 0:14:56 | |
It really is a statement of how rich and powerful I am. | 0:14:56 | 0:14:59 | |
Yes, he was a very wealthy man. | 0:14:59 | 0:15:01 | |
He was a commoner but a wealthy commoner. | 0:15:01 | 0:15:04 | |
He really grasped the opportunity of the Industrial Revolution, didn't he? | 0:15:04 | 0:15:08 | |
He realised that there was money to be made for himself | 0:15:08 | 0:15:11 | |
and basically to benefit the district. | 0:15:11 | 0:15:14 | |
For instance, he was a pioneer in the introduction of the railways. | 0:15:14 | 0:15:17 | |
He invested heavily in the docks. | 0:15:17 | 0:15:19 | |
Much of the estate is on the coalfield. | 0:15:19 | 0:15:21 | |
So apart from agriculture, increasingly, | 0:15:21 | 0:15:25 | |
money was to come from beneath the soil and there was the coal, | 0:15:25 | 0:15:29 | |
there was the black band ironstone, | 0:15:29 | 0:15:31 | |
there was the limestone, all used for smelting. | 0:15:31 | 0:15:34 | |
A real Victorian entrepreneur, really. | 0:15:34 | 0:15:37 | |
A real Victorian entrepreneur. | 0:15:37 | 0:15:39 | |
And with all his achievements, | 0:15:39 | 0:15:40 | |
I'm surprised he wasn't offered a peerage or something like that. | 0:15:40 | 0:15:43 | |
But he was offered a peerage. | 0:15:43 | 0:15:44 | |
In 1869, Gladstone offered him a peerage, which he turned down, | 0:15:44 | 0:15:48 | |
and he was offered one on two further occasions. | 0:15:48 | 0:15:51 | |
At the end of the day, I think he preferred to be | 0:15:51 | 0:15:53 | |
head of the commoners rather than at the tail of the aristocracy. | 0:15:53 | 0:15:57 | |
With the fortunes he made on top of the one he inherited, | 0:15:58 | 0:16:02 | |
Kit Talbot could well afford to model his Margam estate | 0:16:02 | 0:16:06 | |
exactly to his tastes. | 0:16:06 | 0:16:08 | |
And though he died in the 1890s, | 0:16:08 | 0:16:10 | |
the landscape he created here has changed little. | 0:16:10 | 0:16:14 | |
Except, that is, that there are now several rare breeds living here, | 0:16:16 | 0:16:19 | |
some that you won't find anywhere else. | 0:16:19 | 0:16:22 | |
Park manager Mike Wynne is showing me | 0:16:22 | 0:16:25 | |
some of their really special residents, Glamorgan cattle. | 0:16:25 | 0:16:28 | |
So how is it that you have the only surviving herd here? | 0:16:29 | 0:16:32 | |
In 1979, an article appeared in Farmers Weekly, | 0:16:32 | 0:16:36 | |
and a Major Savage from East Sussex claimed to have the last | 0:16:36 | 0:16:41 | |
remaining herd of Glamorgan cattle, and this gentleman | 0:16:41 | 0:16:45 | |
was in his 80s at the time and wanted to give up farming. | 0:16:45 | 0:16:48 | |
And eventually, the West Glamorgan County Council purchased | 0:16:48 | 0:16:54 | |
seven females and three males from this last herd. | 0:16:54 | 0:16:57 | |
Well, you have a fine-looking bull there at the moment. | 0:16:57 | 0:17:00 | |
Is he a Glamorgan? | 0:17:00 | 0:17:02 | |
This is a Gloucester bull which we obtained about two years ago | 0:17:02 | 0:17:05 | |
-from Adam Henson's farm in the Cotswolds. -Really?! | 0:17:05 | 0:17:09 | |
The Rare Breeds Survival Trust thought that the Glamorgan cattle | 0:17:09 | 0:17:12 | |
were quite closely related to the Gloucester cattle, so this | 0:17:12 | 0:17:16 | |
is why we decided to introduce a Gloucester bull into the herd, | 0:17:16 | 0:17:20 | |
to see what we get, really. | 0:17:20 | 0:17:22 | |
So, at the moment, | 0:17:22 | 0:17:23 | |
things are looking quite good for the survival of this breed? | 0:17:23 | 0:17:26 | |
Well, it's early days and we've got a lot do to increase the numbers, | 0:17:26 | 0:17:30 | |
but, yes, we're hoping so. | 0:17:30 | 0:17:31 | |
And that's thanks in no small measure to our Mr Henson. | 0:17:32 | 0:17:36 | |
But it's not just local rare breeds the Margam estate is keeping alive. | 0:17:36 | 0:17:41 | |
Roaming this parkland is an animal from China which is now | 0:17:41 | 0:17:44 | |
so rare that it's extinct in the wild - the Pere David deer. | 0:17:44 | 0:17:49 | |
How did they get from China to the UK? | 0:17:50 | 0:17:53 | |
They were effectively discovered in the Western sense | 0:17:53 | 0:17:55 | |
by French Jesuit missionary Pere David, and he arranged for some | 0:17:55 | 0:18:02 | |
to be sent to Europe, to France, to Germany and to the UK, in the 1860s. | 0:18:02 | 0:18:08 | |
And all the Pere David that now exist in the world | 0:18:08 | 0:18:11 | |
are descended from those animals. | 0:18:11 | 0:18:13 | |
How many are there now left in the world? | 0:18:13 | 0:18:16 | |
I believe there are between 2,000 and 3,000 left in the world. | 0:18:16 | 0:18:20 | |
2,000 or more of them now exist in China, | 0:18:20 | 0:18:22 | |
they've been reintroduced, but they are kept in reserves and parks. | 0:18:22 | 0:18:26 | |
We maintain a herd of about 45 here at Margam. | 0:18:26 | 0:18:29 | |
Now, I must say, Mike, they're not the most attractive of deer species. | 0:18:29 | 0:18:34 | |
Well, yes, the Chinese name translated into English means | 0:18:34 | 0:18:38 | |
the four unlikes. | 0:18:38 | 0:18:39 | |
They're supposed to be made up of part coq, part ass, | 0:18:39 | 0:18:43 | |
-part camel and part deer. -Well, they seem to be thriving here. | 0:18:43 | 0:18:47 | |
Why do you think that is? | 0:18:47 | 0:18:48 | |
Well, Margam was selected as a suitable location | 0:18:48 | 0:18:51 | |
because we have got some marshy wet ground, | 0:18:51 | 0:18:54 | |
which replicates what they would have been used to in China. | 0:18:54 | 0:18:57 | |
So that's a real success story, isn't, for conservation? | 0:18:57 | 0:19:00 | |
Yes, a real success story. | 0:19:00 | 0:19:01 | |
Kit Talbot could never have guessed that one day his great estate | 0:19:06 | 0:19:09 | |
would be owned by the local council, but it means that his land | 0:19:09 | 0:19:13 | |
and the huge impact that he had on it will continue to be preserved. | 0:19:13 | 0:19:18 | |
Sand dunes like the ones on the South Wales coast | 0:19:23 | 0:19:26 | |
are for ever on the move, unless, that is, | 0:19:26 | 0:19:29 | |
these shifting, whispering sands have been too well stabilised. | 0:19:29 | 0:19:33 | |
But sticking out from the North Sea coast, there is a three-mile stretch | 0:19:33 | 0:19:37 | |
of land that's moving westwards at the rate of two metres a year. | 0:19:37 | 0:19:41 | |
It's Spurn Head at the mouth of the River Humber, | 0:19:41 | 0:19:44 | |
and Katie's been there to see what life is like. | 0:19:44 | 0:19:46 | |
Though this spit has been here for hundreds of years, | 0:19:49 | 0:19:51 | |
it's a very dynamic piece of land. It's always on the move. | 0:19:51 | 0:19:55 | |
The sea may have shaped it and built it, | 0:19:55 | 0:19:57 | |
but it also has the power to move it. | 0:19:57 | 0:19:59 | |
Despite this constant shift, people still live and work here. | 0:20:01 | 0:20:04 | |
There's a permanently-manned RNLI lifeboat station at the point, | 0:20:04 | 0:20:07 | |
and piloted boats are on hand to guide vessels through | 0:20:07 | 0:20:10 | |
one of our busiest shipping channels. | 0:20:10 | 0:20:12 | |
Out there on the horizon, just over two miles away, | 0:20:13 | 0:20:16 | |
you can just about make out a Met mast, | 0:20:16 | 0:20:19 | |
which is a piece of equipment used to measure weather conditions. | 0:20:19 | 0:20:22 | |
It also marks the point where the coastline was in Roman times | 0:20:22 | 0:20:26 | |
and that shows you just how much | 0:20:26 | 0:20:27 | |
this landscape has changed over time. | 0:20:27 | 0:20:30 | |
On average, the Spurn moves west up to two metres | 0:20:31 | 0:20:34 | |
or nearly seven feet every year. | 0:20:34 | 0:20:35 | |
It's all down to longshore drift, a natural process that never rests. | 0:20:35 | 0:20:39 | |
I'm meeting geologist Dr Jan Zalasiewicz | 0:20:39 | 0:20:42 | |
from Leicester University to find out more. | 0:20:42 | 0:20:44 | |
-Longshore drift, a classic geography term. -It is, yes. | 0:20:45 | 0:20:49 | |
Can you explain that? | 0:20:49 | 0:20:51 | |
Well, the Spurn is a classic spit which is formed by material | 0:20:51 | 0:20:55 | |
being washed by the sea out of these cliffs of boulder clay. | 0:20:55 | 0:20:59 | |
The waves attack them. | 0:20:59 | 0:21:01 | |
They break them down, literally, at the rate of one or two metres year. | 0:21:01 | 0:21:04 | |
The mud and the sand and the pebbles are washed out. | 0:21:04 | 0:21:07 | |
The waves will carry the pebbles up the beach like this, | 0:21:07 | 0:21:10 | |
normally coming at an angle, and then the backwash comes | 0:21:10 | 0:21:14 | |
and it will simply drop back down the beach here. | 0:21:14 | 0:21:17 | |
The next wave will come, pick it up, take it diagonally again, | 0:21:17 | 0:21:20 | |
and down it goes again, and so it will go on travelling. | 0:21:20 | 0:21:24 | |
It'll do a zigzag along the beach and simply will carry on. | 0:21:24 | 0:21:27 | |
So more and more material will be taken from one side | 0:21:27 | 0:21:30 | |
of the beach right along, and that is how the spit will form. | 0:21:30 | 0:21:33 | |
It helps the spit form. It's an ongoing conveyor belt | 0:21:33 | 0:21:35 | |
which is always coming out of the cliffs, that's the supply, | 0:21:35 | 0:21:38 | |
and it's carrying on down. | 0:21:38 | 0:21:40 | |
And it's just travelling. It will travel for miles and miles. | 0:21:40 | 0:21:43 | |
In the past, man has tried to check this movement | 0:21:47 | 0:21:50 | |
and prevent erosion by protecting the land | 0:21:50 | 0:21:53 | |
from the sea's natural passage. | 0:21:53 | 0:21:54 | |
The Victorians set up a series of sea defences to hold back the waves. | 0:21:54 | 0:21:58 | |
They were maintained by the MoD until the late 1950s. | 0:21:58 | 0:22:01 | |
Since then, the Yorkshire Wildlife Trust has been | 0:22:03 | 0:22:06 | |
responsible for the management of the Spurn, | 0:22:06 | 0:22:08 | |
now a designated national nature reserve. | 0:22:08 | 0:22:11 | |
Andrew Gibson is the full-time warden in charge, | 0:22:14 | 0:22:17 | |
and he's going to show me around the reserve. | 0:22:17 | 0:22:19 | |
-Now, the sea is just over this bank here. -It is, it's over on our left. | 0:22:20 | 0:22:23 | |
When you've got your spring tides, | 0:22:23 | 0:22:25 | |
-is the sea actually washing over this bit of land? -It will come over. | 0:22:25 | 0:22:29 | |
Believe it or not, that's what we want. | 0:22:29 | 0:22:31 | |
We want it to wash over and move westwards, | 0:22:31 | 0:22:34 | |
which is what it would do naturally. | 0:22:34 | 0:22:37 | |
-You want nature to shape this land. -We do. | 0:22:37 | 0:22:40 | |
But we need to manage it for our own benefit as well. | 0:22:40 | 0:22:43 | |
And it's striking that compromise between the two things. | 0:22:43 | 0:22:47 | |
Out we get! Oh, my goodness, it's blowing a gale! | 0:22:53 | 0:22:56 | |
So, what's the important thing | 0:22:59 | 0:23:01 | |
about this bit of road and that bit of road? | 0:23:01 | 0:23:03 | |
That's your traditional tarmac road, which we'd say, bad road. | 0:23:03 | 0:23:07 | |
This is good road. | 0:23:07 | 0:23:08 | |
This is a removable interlocking concrete block. | 0:23:08 | 0:23:11 | |
What it allows it to do is, you can see the sand | 0:23:11 | 0:23:14 | |
migrates over this very easily, and if the dynamic coastline, | 0:23:14 | 0:23:19 | |
as it moves, washes it away, we can pick this material up | 0:23:19 | 0:23:23 | |
and put it back in the recycler and bring it back out. | 0:23:23 | 0:23:25 | |
Whereas the tarmac road is fixed. It's hard. It needs a sub-base. | 0:23:25 | 0:23:30 | |
It's a hard scar on the landscape, shall we say, | 0:23:30 | 0:23:33 | |
whereas what we need is dynamism. | 0:23:33 | 0:23:35 | |
Flexible roads are one way of meeting | 0:23:47 | 0:23:49 | |
the challenge of living on the Spurn. | 0:23:49 | 0:23:51 | |
Keeping the scrub down is a different matter. | 0:23:51 | 0:23:53 | |
When the grass gets too long, you need the right tools for the job. | 0:23:53 | 0:23:57 | |
-So, why do you have sheep here? -To manage this, to manage the grass. | 0:23:57 | 0:24:02 | |
This is fixed dune, it's got its own unique, species-rich grassland, | 0:24:02 | 0:24:07 | |
very much like chalk grassland. | 0:24:07 | 0:24:09 | |
And these sheep are needed to take off all this longer grass, | 0:24:09 | 0:24:13 | |
otherwise it becomes very rank and long | 0:24:13 | 0:24:16 | |
and the flowers in the spring, the orchids, can't come through that. | 0:24:16 | 0:24:19 | |
You could come in and cut it and take it off manually, | 0:24:19 | 0:24:23 | |
but we use these guys. | 0:24:23 | 0:24:25 | |
It's a much more sustainable way of doing it. | 0:24:25 | 0:24:27 | |
These Hebrideans are built for this type of environment | 0:24:31 | 0:24:34 | |
but life on the spit is not for the fainthearted. | 0:24:34 | 0:24:37 | |
It gets a constant battering from the wind and the waves. | 0:24:37 | 0:24:41 | |
Andrew Wells and his wife Sue have been braving the elements here for 15 years. | 0:24:41 | 0:24:45 | |
So, Andrew, why did you decide to come and live here? | 0:24:47 | 0:24:50 | |
Well, basically, we were looking for a small dairy farm that we | 0:24:50 | 0:24:52 | |
could afford and because of the location of this place, | 0:24:52 | 0:24:56 | |
its remoteness and its closeness to the North Sea, | 0:24:56 | 0:24:59 | |
and the erosion problems down here, it was a very cheap dairy farm. | 0:24:59 | 0:25:04 | |
And we ended up as the last dairy farm in this area. | 0:25:04 | 0:25:07 | |
They were coming 40 miles every day to pick our milk up and then | 0:25:07 | 0:25:10 | |
going 40 miles back and it was just obvious that it wasn't sustainable. | 0:25:10 | 0:25:14 | |
So I sold the cows in 2008 and we now make a living doing a bit | 0:25:14 | 0:25:19 | |
of beef farming, but we make the most of our living from bed-and-breakfast. | 0:25:19 | 0:25:23 | |
What's it like to live here? | 0:25:23 | 0:25:25 | |
Well, I'll tell you what it's like in the summer. | 0:25:25 | 0:25:27 | |
I used to come down here to fetch my cows in, | 0:25:27 | 0:25:29 | |
first thing in the morning, in the summer at about 5:30, | 0:25:29 | 0:25:32 | |
and you would look down there and you could see the sun rising over | 0:25:32 | 0:25:35 | |
the sea and you look over there and you could see the ferries | 0:25:35 | 0:25:37 | |
coming in up the estuary. | 0:25:37 | 0:25:39 | |
I just used to stand somewhere around about here every morning, | 0:25:39 | 0:25:42 | |
just for a minute, then I would get on with my day's work, and at | 0:25:42 | 0:25:45 | |
the end of the minute, I used to say to myself, "You lucky, lucky man." | 0:25:45 | 0:25:49 | |
-Yeah. -Because it's absolutely gorgeous in the summer. | 0:25:49 | 0:25:52 | |
-And in the winter? -It's pretty bleak! | 0:25:52 | 0:25:54 | |
THEY LAUGH | 0:25:54 | 0:25:56 | |
Summertime it ain't but even in the depths of winter, | 0:25:58 | 0:26:01 | |
this wild and windswept spit of land has a charm all of its own. | 0:26:01 | 0:26:05 | |
Back on the South Wales coast, I've been seeing how engineering | 0:26:17 | 0:26:21 | |
has given conservation a helping hand to rejuvenate its sand dunes. | 0:26:21 | 0:26:25 | |
Well, this is the effect of the work that was done last year. | 0:26:31 | 0:26:34 | |
You can see there is still an enormous amount of open sand | 0:26:34 | 0:26:38 | |
and a lot of water, evidence of an incredibly wet year. | 0:26:38 | 0:26:43 | |
But fingers crossed, with a lot of wind and a much drier year, | 0:26:43 | 0:26:48 | |
this place should look like the Sahara of Wales come next January. | 0:26:48 | 0:26:52 | |
Later, I will be finding out for myself how running up | 0:26:53 | 0:26:56 | |
and down these dunes is helping to maintain them, | 0:26:56 | 0:26:59 | |
when I join the local college rugby team out on a training exercise. | 0:26:59 | 0:27:03 | |
But first, Tom has been discovering how we are burning wood | 0:27:03 | 0:27:07 | |
and crops to help fight climate change. | 0:27:07 | 0:27:10 | |
But as the use of biomass increases, could it actually | 0:27:10 | 0:27:13 | |
damage the very environment it is supposed to protect? | 0:27:13 | 0:27:17 | |
I have been visiting two very different biomass producers. | 0:27:21 | 0:27:25 | |
In Yorkshire, a farmer growing willow crops to satisfy | 0:27:25 | 0:27:28 | |
the demand of Britain's largest power producer. | 0:27:28 | 0:27:31 | |
And at Richmond Park in London, a small-scale scheme, | 0:27:33 | 0:27:37 | |
selling on the waste wood from routine forest management | 0:27:37 | 0:27:40 | |
to an expanding local business. | 0:27:40 | 0:27:42 | |
Although, as I'm discovering, it's not your average pub or cornershop. | 0:27:44 | 0:27:49 | |
Well, if you are wondering what this emerging building is, | 0:27:49 | 0:27:53 | |
step out here and the sight and sound should give you | 0:27:53 | 0:27:56 | |
a bit of a clue. | 0:27:56 | 0:27:58 | |
Yup, we're in the heart of Heathrow Airport. | 0:27:58 | 0:28:01 | |
There's a Jumbo just taking off. | 0:28:01 | 0:28:03 | |
And this entire building, the new Terminal Two, | 0:28:03 | 0:28:07 | |
will be at least partly heated and powered by burning wood. | 0:28:07 | 0:28:12 | |
25,000 tonnes of woodchip will be burned here every year, all coming | 0:28:12 | 0:28:17 | |
from forest management projects within 100 miles of the airport. | 0:28:17 | 0:28:22 | |
So when passengers are coming through here in | 0:28:22 | 0:28:25 | |
a year and a half's time, | 0:28:25 | 0:28:27 | |
how much are they going to be kept warm by wood? | 0:28:27 | 0:28:29 | |
So 20% of all of the heat | 0:28:29 | 0:28:31 | |
and also the electricity for the new Terminal Two will come from wood. | 0:28:31 | 0:28:35 | |
Heathrow is a big energy consumer, so this is one of the steps | 0:28:35 | 0:28:39 | |
we can take to cut our carbon emissions from the airport. | 0:28:39 | 0:28:42 | |
But in the grand scheme of things, | 0:28:44 | 0:28:45 | |
projects like this can only generate a small amount of power. | 0:28:45 | 0:28:48 | |
Surely something much bigger would be even better, wouldn't it? | 0:28:48 | 0:28:53 | |
Drax in Yorkshire is Britain's largest power station | 0:28:59 | 0:29:02 | |
and its biggest single polluter, burning coal to provide us | 0:29:02 | 0:29:08 | |
with the electricity we use every day. | 0:29:08 | 0:29:11 | |
But you might be surprised to learn that it is also increasingly | 0:29:11 | 0:29:15 | |
turning to renewable energy. | 0:29:15 | 0:29:16 | |
A massive transformation is taking place here as Drax | 0:29:18 | 0:29:21 | |
changes its diet, changes the fuel it consumes, | 0:29:21 | 0:29:24 | |
that means an awful lot of building. | 0:29:24 | 0:29:26 | |
Not least, this extraordinary space-age structure, | 0:29:26 | 0:29:30 | |
which is to store that most traditional of fuels, wood. | 0:29:30 | 0:29:34 | |
There will be enough in one of these to keep a million homes | 0:29:34 | 0:29:37 | |
powered for three weeks. | 0:29:37 | 0:29:40 | |
'From the outside, it looks big. | 0:29:40 | 0:29:44 | |
'From the inside, it is something else.' | 0:29:44 | 0:29:47 | |
-Whoa! -Impressive, isn't it? -It's amazing! | 0:29:47 | 0:29:50 | |
'Head of Environment Nigel Burdett is giving me the grand tour.' | 0:29:50 | 0:29:54 | |
It's an extraordinary space. | 0:29:54 | 0:29:55 | |
So if I was here later this year, I would be buried in wood, would I? | 0:29:55 | 0:29:58 | |
-You would indeed be buried in wood, yes. -Incredible building. | 0:29:58 | 0:30:01 | |
Feels a bit like a Bond villain's lair, doesn't it? | 0:30:01 | 0:30:03 | |
-Very much like that, yes. -Inside the volcano! | 0:30:03 | 0:30:07 | |
The willow I helped harvest earlier will be used to feed this | 0:30:07 | 0:30:11 | |
ambitious project, as are many other farms | 0:30:11 | 0:30:14 | |
and forests all brought on board to help supply this 7 million tonnes | 0:30:14 | 0:30:18 | |
of plants and wood that will be burned here every year. | 0:30:18 | 0:30:23 | |
What we have been doing over the last decade or so has been | 0:30:23 | 0:30:26 | |
gradually increasing the amount of biomass through the plant | 0:30:26 | 0:30:29 | |
and we are mixing biomass in relatively small amounts with | 0:30:29 | 0:30:32 | |
coal, so up to about 10% of our total throughput has been biomass. | 0:30:32 | 0:30:37 | |
Into the future, we are looking at a fairly major transformation, | 0:30:37 | 0:30:41 | |
taking three of our six units | 0:30:41 | 0:30:43 | |
and converting each of those to 100% biomass. | 0:30:43 | 0:30:46 | |
So, rather than being a minority biomass, it will be close to half and half? | 0:30:46 | 0:30:50 | |
Close to half and half in the next few years, absolutely. | 0:30:50 | 0:30:53 | |
Biomass gives you a very good saving compared to coal. | 0:30:54 | 0:30:57 | |
And we think the amount of CO2 emitted, 70% to 80% saving | 0:30:57 | 0:31:03 | |
compared to the coal we are burning at Drax at present. | 0:31:03 | 0:31:05 | |
This sounds like great news. | 0:31:05 | 0:31:09 | |
But groups including the RSPB claim that when you create | 0:31:09 | 0:31:13 | |
biomass on this scale, its carbon savings can disappear. | 0:31:13 | 0:31:18 | |
You get the danger that wood | 0:31:18 | 0:31:20 | |
is from unsustainably managed, intensive forests, | 0:31:20 | 0:31:24 | |
a long way away, because you can't source enough from your local area. | 0:31:24 | 0:31:27 | |
That then all has to be shipped, | 0:31:27 | 0:31:28 | |
potentially halfway across the world, it has to be processed, | 0:31:28 | 0:31:31 | |
it has to be delivered, | 0:31:31 | 0:31:32 | |
and you have already got a lot of carbon emissions right there, | 0:31:32 | 0:31:35 | |
plus you are probably not taking just waste wood, | 0:31:35 | 0:31:38 | |
you are probably taking, or are in danger of taking, whole trees, | 0:31:38 | 0:31:41 | |
and that is where we know we incur the biggest carbon debt, | 0:31:41 | 0:31:44 | |
because that wood is all being burned, | 0:31:44 | 0:31:45 | |
all that carbon is going into the atmosphere | 0:31:45 | 0:31:47 | |
and the atmosphere sees it as a greenhouse gas, just like any other. | 0:31:47 | 0:31:50 | |
Although Drax do use some local suppliers, | 0:31:52 | 0:31:54 | |
like the farmer I met earlier, 90% of its biomass | 0:31:54 | 0:31:59 | |
will be imported from forests in Canada and the USA. | 0:31:59 | 0:32:03 | |
But they insist this doesn't affect its green credentials. | 0:32:03 | 0:32:07 | |
We have a very important, | 0:32:07 | 0:32:09 | |
robust sustainability policy in place, which ensures that | 0:32:09 | 0:32:13 | |
all our wood is coming from forests which are essentially replanted | 0:32:13 | 0:32:17 | |
and we are not taking any more material from that forest | 0:32:17 | 0:32:20 | |
-than is actually growing. -And that really is the case, is it? | 0:32:20 | 0:32:23 | |
If I went over there, to those forests, | 0:32:23 | 0:32:25 | |
I would be able to see more trees growing than are being taken away? | 0:32:25 | 0:32:28 | |
-That is the absolute plan, yes. -Right, it's the plan, or is it the reality? | 0:32:28 | 0:32:31 | |
We do have a reality indeed, yes. We do audits as well to make sure that | 0:32:31 | 0:32:35 | |
we are in fact taking material from sustainable forests wherever we can. | 0:32:35 | 0:32:39 | |
All the signs are that biomass looks set to play an increasingly | 0:32:42 | 0:32:46 | |
important part in our energy mix and many are embracing its potential. | 0:32:46 | 0:32:51 | |
To take big chunks out of our carbon emissions, | 0:32:51 | 0:32:55 | |
we need to think big. | 0:32:55 | 0:32:57 | |
But when it comes to burning wood and other plant material, | 0:32:57 | 0:33:01 | |
greater scale must be accompanied by greater scrutiny. | 0:33:01 | 0:33:04 | |
What is being burned? How is it transported? | 0:33:04 | 0:33:07 | |
What is being planted in its place? | 0:33:07 | 0:33:09 | |
Without the right answers to those questions, | 0:33:09 | 0:33:12 | |
the green credentials of this fuel just go up in smoke. | 0:33:12 | 0:33:15 | |
We've been exploring the shores of South Wales. | 0:33:22 | 0:33:26 | |
Hidden inland, beyond the coast's undulating dunes, | 0:33:26 | 0:33:29 | |
is an astonishing story that I am about to uncover. | 0:33:29 | 0:33:33 | |
Towards the end of the Second World War, | 0:33:37 | 0:33:40 | |
in a prison camp on the outskirts of Bridgend, | 0:33:40 | 0:33:43 | |
German captives drew sketches of saucy ladies on the walls. | 0:33:43 | 0:33:47 | |
The alluring pictures were a distraction. | 0:33:48 | 0:33:51 | |
Because, in great secrecy, an audacious plot was being hatched. | 0:33:51 | 0:33:56 | |
In 1945, this stretch of coastline saw a mass escape - | 0:33:59 | 0:34:03 | |
the biggest breakout by German prisoners of war on UK soil | 0:34:03 | 0:34:07 | |
during the Second World War. | 0:34:07 | 0:34:09 | |
70 of them escaped through a tunnel, | 0:34:09 | 0:34:12 | |
which they dug right under the noses of their guards. | 0:34:12 | 0:34:15 | |
A dramatic story of deceit, courage | 0:34:15 | 0:34:18 | |
and, for them all, ultimate recapture. | 0:34:18 | 0:34:21 | |
It became known as the Welsh Great Escape. | 0:34:21 | 0:34:24 | |
Using the latest computer technology, | 0:34:25 | 0:34:28 | |
I am going to update this remarkable event. | 0:34:28 | 0:34:31 | |
It all happened here at an old farm that had been | 0:34:32 | 0:34:35 | |
converted into a prison camp. | 0:34:35 | 0:34:37 | |
It was in this hut that the German prisoners of war | 0:34:44 | 0:34:46 | |
hatched their plot to escape. | 0:34:46 | 0:34:48 | |
And in this room, beneath where a bunk would have stood, | 0:34:53 | 0:34:56 | |
was their secret gateway to freedom. This was the entrance of the tunnel. | 0:34:56 | 0:35:00 | |
It has been blocked up for decades, but we think the tunnel still exists. | 0:35:02 | 0:35:06 | |
So I have called in a crack team to help me unlock its secrets. | 0:35:06 | 0:35:10 | |
We have been granted special permission to dig down to it. | 0:35:10 | 0:35:14 | |
Nick Russell is a world-class laser mapping specialist and for the | 0:35:15 | 0:35:20 | |
first time, he's going to bring the escape tunnel to life in 3D. | 0:35:20 | 0:35:24 | |
What we have now got available to us is an instrument called | 0:35:24 | 0:35:27 | |
a 3D laser scanner, | 0:35:27 | 0:35:29 | |
and that lets us record a three-dimensional model of the tunnel, | 0:35:29 | 0:35:33 | |
so we will be able to reconstruct the escape, | 0:35:33 | 0:35:35 | |
if you like, by flying through the hut and down the tunnel. | 0:35:35 | 0:35:39 | |
Brett Exton has been studying the great escape for 12 years | 0:35:41 | 0:35:45 | |
and hopes to make some new discoveries. | 0:35:45 | 0:35:49 | |
We are hoping we might be able to find all manner of things. | 0:35:49 | 0:35:52 | |
A second or third tunnel would be ideal. | 0:35:52 | 0:35:55 | |
-This one might have collapsed, even! -It could well have collapsed by now. | 0:35:55 | 0:35:59 | |
Nick and the digger are busy excavating a way into the tunnel, so | 0:35:59 | 0:36:02 | |
there is time for me to find out some more about the prisoners themselves. | 0:36:02 | 0:36:07 | |
Well, what do you know, Brett, about the men who were prisoners here? | 0:36:08 | 0:36:11 | |
Well, initially, when the prisoners came here in November 1944, | 0:36:11 | 0:36:16 | |
there was about 2,000 of them brought here. | 0:36:16 | 0:36:19 | |
And they were from all manner of the German military. | 0:36:19 | 0:36:23 | |
You had army personnel, you had Luftwaffe, you had sailors, | 0:36:23 | 0:36:27 | |
and so forth. So they were all ranks. | 0:36:27 | 0:36:30 | |
And when did these 70 men escape? | 0:36:30 | 0:36:32 | |
Well, they came in November 1944 and on March 10th, 1945, | 0:36:32 | 0:36:38 | |
they escaped through a tunnel. | 0:36:38 | 0:36:39 | |
So that only gave them five months to undertake an incredible feat | 0:36:39 | 0:36:44 | |
-of German engineering. -How did they do it? | 0:36:44 | 0:36:46 | |
How did they hoodwink the guards? | 0:36:46 | 0:36:48 | |
There is all sorts of different methods that they used. | 0:36:48 | 0:36:52 | |
The one for the tunnel itself, | 0:36:52 | 0:36:54 | |
directly above the tunnel entrance, they drew a scantily-clad lady. | 0:36:54 | 0:36:58 | |
As the guards came in to do the exploration of the room, | 0:36:58 | 0:37:02 | |
they would have been distracted by the scantily-clad lady. | 0:37:02 | 0:37:06 | |
It is clay, the soil, isn't it? How did they get rid of that? | 0:37:06 | 0:37:09 | |
Well, that is really ingenious, | 0:37:09 | 0:37:12 | |
because inside the toilet block, | 0:37:12 | 0:37:14 | |
they fastened onto the end of the wall a false cavity. | 0:37:14 | 0:37:17 | |
They made a cavity, put a little air vent in the top corner of it, | 0:37:17 | 0:37:21 | |
and as the soil came out of the tunnel, they would have | 0:37:21 | 0:37:23 | |
squished it into a ball and I've got one in my pocket to show you. | 0:37:23 | 0:37:27 | |
That is a genuine clay ball. | 0:37:27 | 0:37:28 | |
Then they would have taken the vent out of the wall | 0:37:28 | 0:37:30 | |
-and plopped the ball behind it. -And nobody spotted it? -Nobody spotted it. | 0:37:30 | 0:37:35 | |
The clay lay undetected until about the 1980s, | 0:37:35 | 0:37:39 | |
when the wall collapsed and all the soil spilt out. | 0:37:39 | 0:37:43 | |
By the night of March 10th, 1945, the tunnel was finished. | 0:37:43 | 0:37:48 | |
The men were ready. At 10 o'clock, the first prisoners made a run for it. | 0:37:48 | 0:37:53 | |
SIREN WAILS | 0:37:53 | 0:37:55 | |
By the next morning, 70 of them | 0:37:55 | 0:37:57 | |
were at large in the South Wales countryside. | 0:37:57 | 0:38:00 | |
Some got surprisingly far. | 0:38:00 | 0:38:02 | |
I'll mark the prison camp with the sentry there. | 0:38:05 | 0:38:07 | |
Well, four of them went about a mile up the road from here. | 0:38:07 | 0:38:12 | |
They found a doctor's car. | 0:38:12 | 0:38:14 | |
Obviously, cars would have been a luxury during the war. | 0:38:14 | 0:38:16 | |
And they had trouble getting the car started, | 0:38:16 | 0:38:19 | |
so they were pushing the car down the road when some guards | 0:38:19 | 0:38:22 | |
coming the other way back to the camp noticed them. | 0:38:22 | 0:38:25 | |
But the prisoners managed to convince them they were Norwegians. | 0:38:25 | 0:38:29 | |
And they said to the Norwegians, | 0:38:29 | 0:38:31 | |
"Get in the car and we'll give you a push start." | 0:38:31 | 0:38:33 | |
So the guards from the farm actually got the first four off and running! | 0:38:33 | 0:38:37 | |
They got hopelessly lost, ended up in Gloucester, | 0:38:37 | 0:38:39 | |
abandoned the car, went on foot towards Birmingham... | 0:38:39 | 0:38:42 | |
-And then got captured. -Then got captured. | 0:38:42 | 0:38:44 | |
What was the furthest distance that anybody got? | 0:38:44 | 0:38:46 | |
Well, some of them managed to catch a train | 0:38:46 | 0:38:49 | |
and they got down as far as Southampton. | 0:38:49 | 0:38:52 | |
-They made it to the coast. -Yes. | 0:38:52 | 0:38:54 | |
After a week, the last of them | 0:38:54 | 0:38:56 | |
were recaptured in a village just 20 miles away. | 0:38:56 | 0:38:59 | |
We've managed to find a lady who 68 years ago was there | 0:39:01 | 0:39:05 | |
when the final three German soldiers surrendered in her sitting room. | 0:39:05 | 0:39:09 | |
And she will be telling us the story later in the programme. | 0:39:09 | 0:39:13 | |
Down on the farm, | 0:39:18 | 0:39:19 | |
Adam is rounding up his flock for a routine pregnancy scan. | 0:39:19 | 0:39:24 | |
It is vital he has plenty of new lambs in spring, | 0:39:24 | 0:39:26 | |
so he is hoping for some good results. | 0:39:26 | 0:39:29 | |
Today we are scanning about a third of our ewes already in lamb, | 0:39:36 | 0:39:40 | |
which is about 250 sheep. | 0:39:40 | 0:39:42 | |
It is a skilled job, | 0:39:42 | 0:39:44 | |
so we have called in sheep scanner Wally Chandler. | 0:39:44 | 0:39:48 | |
-Hi, Wally. -Hi, Adam. | 0:39:48 | 0:39:49 | |
-Good to see you. It's been over a year. -Yeah! Yeah, it certainly has. | 0:39:49 | 0:39:52 | |
-It was your first year, wasn't it? -It was my first big season. | 0:39:52 | 0:39:56 | |
-And have you had a bit of experience since? -I have, yes, certainly. | 0:39:56 | 0:39:59 | |
I finished that season, so I scanned quite a few out of the UK. | 0:39:59 | 0:40:02 | |
And then I went to New Zealand at the end of June, | 0:40:02 | 0:40:05 | |
-for the best part of two months. -Crikey! -And that was brilliant. | 0:40:05 | 0:40:08 | |
So how many thousands of sheep have you scanned? | 0:40:08 | 0:40:10 | |
-Well, in New Zealand, I did about 52,000 in 28 days. -No! | 0:40:10 | 0:40:14 | |
That was pretty good going. So that's about 2,000 a day. | 0:40:14 | 0:40:17 | |
-Some days were easy. My biggest day was 2,500. -Wow! | 0:40:17 | 0:40:21 | |
One of the things we are worried about this year is a disease | 0:40:23 | 0:40:26 | |
called Schmallenberg. | 0:40:26 | 0:40:28 | |
It's spread by midges and can cause infertility | 0:40:28 | 0:40:30 | |
and deformity in unborn lambs and calves. | 0:40:30 | 0:40:34 | |
And often when the scanner is here, | 0:40:34 | 0:40:36 | |
he can tell if the ewes are empty | 0:40:36 | 0:40:37 | |
and if that is a higher than usual number, | 0:40:37 | 0:40:40 | |
then there is a risk that might be Schmallenberg. | 0:40:40 | 0:40:43 | |
Have you found any signs of it this year, Wally? | 0:40:43 | 0:40:45 | |
So far, everything has been absolutely fantastic. | 0:40:45 | 0:40:48 | |
I mean, admittedly, I am not going to go and see fused limbs on my scanner. | 0:40:48 | 0:40:53 | |
I will see aborted pregnancies and pregnancies that are about to abort, | 0:40:53 | 0:40:56 | |
and I'll see a dead lamb, but I'm not going to see a fused limb. | 0:40:56 | 0:40:59 | |
So if the pregnancy is fine when I scan it, that's all I can say. | 0:40:59 | 0:41:03 | |
From my point of view, everything is going really well. | 0:41:03 | 0:41:06 | |
And there's lots of lambs around, lots of lambs. | 0:41:06 | 0:41:08 | |
You're just like a breath of fresh air, Wally! Such a positive man! | 0:41:08 | 0:41:13 | |
This one's empty... I'm joking! | 0:41:13 | 0:41:15 | |
No, she's a late single. | 0:41:15 | 0:41:17 | |
With the Schmallenberg virus already affecting some farms, | 0:41:19 | 0:41:22 | |
you never know how the year will turn out. | 0:41:22 | 0:41:24 | |
And arable farming is no different. | 0:41:24 | 0:41:26 | |
It can be a huge gamble | 0:41:26 | 0:41:28 | |
and its success or failure is in the hands of mother nature. | 0:41:28 | 0:41:31 | |
Last year was the wettest year on record in England. | 0:41:31 | 0:41:35 | |
And farmers had a pretty tough time of it. | 0:41:35 | 0:41:38 | |
And now, the start of the new year, there is snow on the ground | 0:41:38 | 0:41:42 | |
and there are still people out harvesting root crops. | 0:41:42 | 0:41:45 | |
And there is one root crop that I know very little about. | 0:41:45 | 0:41:47 | |
And most of us eat it most days. | 0:41:47 | 0:41:50 | |
And I'm hoping over here in the Eastern counties, | 0:41:50 | 0:41:53 | |
they're going to be lifting some today. | 0:41:53 | 0:41:55 | |
MUSIC: "Sugar Sugar" by The Archies | 0:41:55 | 0:41:59 | |
If you haven't guessed already, that crop is sugar beet. | 0:41:59 | 0:42:03 | |
The average person consumes 2.3 tonnes of sugar in their lifetime. | 0:42:03 | 0:42:08 | |
And it is our love and addiction to the stuff | 0:42:08 | 0:42:10 | |
that creates such a huge demand. | 0:42:10 | 0:42:12 | |
Here we are, this is the stuff I'm after. Sugar beet. | 0:42:12 | 0:42:15 | |
And I'm going to be following it from the fields to the factory, | 0:42:15 | 0:42:19 | |
all the way through to a bag of sugar. | 0:42:19 | 0:42:21 | |
'Ken Rush and Jamie Gwatkin have worked in the sugar beet | 0:42:24 | 0:42:27 | |
'industry most of their lives and even on a snowy morning, | 0:42:27 | 0:42:31 | |
'nothing stops them lifting the crop.' | 0:42:31 | 0:42:33 | |
-Hi, Jamie. -Hello, Adam, how are you? | 0:42:33 | 0:42:35 | |
-Very well, thanks. Hi, Ken. -Morning. -Goodness me, it's all go! | 0:42:35 | 0:42:38 | |
Absolutely. I tell you, even on a day with two inches of snow, | 0:42:38 | 0:42:42 | |
-everything is happening in the fields still. -And you help co-ordinate it? | 0:42:42 | 0:42:46 | |
We do, yeah. | 0:42:46 | 0:42:47 | |
Well, I'm the administrator of the Bury Beet Group, | 0:42:47 | 0:42:50 | |
which is a group of 34 farmers today, delivering 153,000 tonnes | 0:42:50 | 0:42:56 | |
of sugar beet into the Bury St Edmunds factory. | 0:42:56 | 0:42:58 | |
Now, a lot of people imagine sugar comes from sugar cane from abroad | 0:42:58 | 0:43:02 | |
and wouldn't realise that it is grown in this country. | 0:43:02 | 0:43:05 | |
Well, I don't know if you are aware, but 50% of the sugar that is | 0:43:05 | 0:43:09 | |
consumed in the UK is grown from sugar beet, rather than | 0:43:09 | 0:43:13 | |
cane sugar, which is grown in the Afro-Caribbean countries. | 0:43:13 | 0:43:16 | |
And how long have you been involved in growing | 0:43:16 | 0:43:18 | |
and delivering sugar beet? | 0:43:18 | 0:43:20 | |
Well, this is my 60th year. | 0:43:20 | 0:43:23 | |
Which is making me age a bit, | 0:43:23 | 0:43:26 | |
but I still enjoy the job, | 0:43:26 | 0:43:29 | |
and I hope I can do a few more years yet. | 0:43:29 | 0:43:31 | |
And what was it like in the old days, how has it changed? | 0:43:31 | 0:43:34 | |
Well, I've got a hook here and it's changed. | 0:43:34 | 0:43:37 | |
In the old days, we used to have to get sugar beet | 0:43:37 | 0:43:40 | |
out of the ground like this | 0:43:40 | 0:43:41 | |
and chop the tops off, | 0:43:41 | 0:43:43 | |
put them on a heap, then somebody would come along with a fork | 0:43:43 | 0:43:46 | |
and put them in a horse and tumble, that's how we started... | 0:43:46 | 0:43:48 | |
-Goodness me! -..when I first left school. | 0:43:48 | 0:43:50 | |
Well, you did that very skilfully, you haven't lost the touch, | 0:43:50 | 0:43:53 | |
and now you've got this massive machine that's worth what? | 0:43:53 | 0:43:57 | |
About 350,000. | 0:43:57 | 0:43:58 | |
'The harvested sugar beet is stored in heaps and another | 0:44:06 | 0:44:09 | |
'specialist piece of equipment is used to load the lorries.' | 0:44:09 | 0:44:13 | |
Oh, this is a pretty fancy bit of kit, Ken. | 0:44:13 | 0:44:15 | |
Yes, it's a new, comparatively new, machine to this country over the last few years, | 0:44:15 | 0:44:19 | |
a load of 30 tonnes in around four to five minutes on average. | 0:44:19 | 0:44:22 | |
And time is of an essence, isn't it, Jamie? | 0:44:24 | 0:44:27 | |
Absolutely, I mean, the most critical thing is to deliver | 0:44:27 | 0:44:30 | |
the sugar beet into the factory as soon as possible. | 0:44:30 | 0:44:32 | |
Well, that's where I'm off to now. I'm off to the sugar beet factory. | 0:44:32 | 0:44:36 | |
It's great to see you both and good luck with the rest of the harvest. | 0:44:36 | 0:44:39 | |
-Thank you very much. -Bye. -Bye. | 0:44:39 | 0:44:40 | |
'The lorries travel a short distance to the factory | 0:44:40 | 0:44:45 | |
'where the long process of turning this root crop into granulated sugar begins. | 0:44:45 | 0:44:49 | |
'Agricultural business manager Dan Downs has kindly offered | 0:44:50 | 0:44:53 | |
'to show me around.' | 0:44:53 | 0:44:56 | |
-Hi, Dan. -Hello. -Got our protective clothing on now. | 0:44:56 | 0:44:59 | |
I've often driven past the factory here and seen the steam | 0:44:59 | 0:45:03 | |
billowing into the sky and wondering what goes on in here. | 0:45:03 | 0:45:06 | |
-It's pretty busy, isn't it? -Yes, we're going well at the moment. | 0:45:06 | 0:45:10 | |
We have 550 lorryloads a day coming into this site, | 0:45:10 | 0:45:13 | |
so anybody who travels round near this factory at some point | 0:45:13 | 0:45:17 | |
will have followed a beet lorry at some point. | 0:45:17 | 0:45:19 | |
And so we weigh the lorries in and that's where | 0:45:19 | 0:45:22 | |
we test for the amount of sugar in each individual load of beet. | 0:45:22 | 0:45:26 | |
And then where does it go? | 0:45:26 | 0:45:27 | |
And then, from here, they go up to be offloaded up onto the big area | 0:45:27 | 0:45:30 | |
of concrete where it gets ready for going into the factory. | 0:45:30 | 0:45:33 | |
-Can we have a look at that? -Yeah, let's go. | 0:45:33 | 0:45:35 | |
Goodness me! What a sight! That is a serious scale, isn't it? | 0:45:40 | 0:45:44 | |
Yeah, like, we've got about 20,000 tonnes of beet here, | 0:45:44 | 0:45:48 | |
Adam, on here at the moment. Really what happens is, | 0:45:48 | 0:45:51 | |
this factory processes about 13,000 tonnes of beet a day | 0:45:51 | 0:45:56 | |
and about just over half of this will disappear. | 0:45:56 | 0:45:58 | |
How do you get all this sugar beet into the factory? | 0:45:58 | 0:46:00 | |
It actually all starts with a yellow loading shovel | 0:46:00 | 0:46:03 | |
and it pushes the beet into a central flume that washes | 0:46:03 | 0:46:06 | |
the beet round by using lots of water at high pressure | 0:46:06 | 0:46:09 | |
and then we clean the beet off. | 0:46:09 | 0:46:12 | |
'These machines remove soil, stones and any unwanted material, | 0:46:12 | 0:46:16 | |
'before they're washed in what is basically a huge washing machine. | 0:46:16 | 0:46:20 | |
'Once they're cleaned, they're shredded.' | 0:46:22 | 0:46:25 | |
These are the same beet that you saw in the park, | 0:46:25 | 0:46:27 | |
they have now been sliced up in big slicing machines. | 0:46:27 | 0:46:30 | |
You can see them on the belt behind you, carrying on for processing. | 0:46:30 | 0:46:34 | |
We then mix those with hot water | 0:46:34 | 0:46:36 | |
and it's just the same as you'd have a teacup at home - | 0:46:36 | 0:46:39 | |
the sugar naturally comes out of the slices of beet into the water | 0:46:39 | 0:46:44 | |
and then it goes on from there to the next stage in the process. | 0:46:44 | 0:46:48 | |
'And it's these huge vats that extract the sugar from the beet. | 0:46:49 | 0:46:52 | |
'Eventually crystallisation occurs and the granules are formed. | 0:46:52 | 0:46:56 | |
'The sugar is then packed by a neighbouring factory, | 0:46:57 | 0:47:01 | |
'where it's ready for the shelf.' | 0:47:01 | 0:47:02 | |
We've now come from the main factory into the final packaging plant | 0:47:03 | 0:47:07 | |
here in Bury St Edmunds, so we've come all the way from the field, | 0:47:07 | 0:47:11 | |
all the way now to here, which has only been an average of 28 miles | 0:47:11 | 0:47:15 | |
from the farm, all the way to getting fine, white crystal in the packet. | 0:47:15 | 0:47:19 | |
It's just a great story, isn't it? From when the farmer planted | 0:47:19 | 0:47:22 | |
the beet back in the spring, I suppose it's a year's hard work | 0:47:22 | 0:47:26 | |
to get to the final product from those dirty beet I saw this morning. | 0:47:26 | 0:47:30 | |
-It's just fantastic. -That's the full story. | 0:47:30 | 0:47:32 | |
'Next week, I'm back on the farm, | 0:47:36 | 0:47:38 | |
'tending to my animals in some challenging conditions.' | 0:47:38 | 0:47:41 | |
'I've left behind the dunes at Kenfig | 0:47:50 | 0:47:52 | |
'and travelled seven miles along the coast to visit | 0:47:52 | 0:47:55 | |
'what is the granddaddy of the whole dune system - the Big Dipper at Merthyr Mawr. | 0:47:55 | 0:47:59 | |
'Its soft sand and steep incline | 0:48:02 | 0:48:03 | |
'make it the perfect natural training ground. | 0:48:03 | 0:48:06 | |
'Many sporty sorts have endured a muscle-burning workout | 0:48:06 | 0:48:09 | |
'on these dunes, even Olympic gold medallist Steve Ovett.' | 0:48:09 | 0:48:12 | |
Go on, Tom, off you go. Big dive. Good dive, well done. | 0:48:12 | 0:48:15 | |
Back you come, bring the ball back. | 0:48:15 | 0:48:17 | |
'And if it's good enough for an Olympic champion, | 0:48:17 | 0:48:20 | |
'it's good enough for Bridgend College Rugby Club.' | 0:48:20 | 0:48:23 | |
-So, Dean, you're one of the coaches of this lot. -Yeah. | 0:48:23 | 0:48:25 | |
You've trained on sand before, I'm taking it? | 0:48:25 | 0:48:27 | |
I've trained here before, yes. | 0:48:27 | 0:48:29 | |
All of this comes from training on the sand? | 0:48:29 | 0:48:31 | |
I don't know about that, yeah, it's very tough. | 0:48:31 | 0:48:33 | |
Why do you like to bring your lads down here? | 0:48:33 | 0:48:35 | |
It's just going to improve their fitness and their skills as well. | 0:48:35 | 0:48:38 | |
When they're tired, it's good decision-making. | 0:48:38 | 0:48:40 | |
And some of these lads have got a match tomorrow. | 0:48:40 | 0:48:42 | |
I think a few of them have, yes. | 0:48:42 | 0:48:43 | |
So you've got to be a little bit careful. | 0:48:43 | 0:48:45 | |
Don't tell the club coaches! | 0:48:45 | 0:48:47 | |
'The lads practise their gameplay over and over again, | 0:48:47 | 0:48:50 | |
'up the strength-sapping Big Dipper. | 0:48:50 | 0:48:52 | |
'These individual training benefits are about to become clear to me.' | 0:48:52 | 0:48:56 | |
Matt, we're subbing you in, in you go, into the second row. | 0:48:56 | 0:48:59 | |
Here we go, lads, ready? | 0:48:59 | 0:49:01 | |
Oh, it's lovely, it was high! | 0:49:06 | 0:49:08 | |
'I feel slightly guilty for setting them off on yet another drill, but who knows? | 0:49:08 | 0:49:12 | |
'Maybe one day with the help of their local dunes, | 0:49:12 | 0:49:15 | |
'some of these lads will be scoring in the Six Nations. | 0:49:15 | 0:49:19 | |
'Well, it was a good warm-up but they're not finished with me yet. | 0:49:19 | 0:49:22 | |
'Can I hold my own in a race to the top?' | 0:49:22 | 0:49:25 | |
Yeah, I'll let the wingers crack on, I'll pace myself. | 0:49:29 | 0:49:33 | |
Now, in a moment, John will be revealing | 0:49:33 | 0:49:35 | |
the results of the 3D mapping of the tunnel dug by 70 Germans, | 0:49:35 | 0:49:38 | |
but while I crack on with the rest of this hill, why don't you | 0:49:38 | 0:49:41 | |
have a look and see what the weather is got in store for the week ahead? | 0:49:41 | 0:49:44 | |
. | 0:51:50 | 0:51:57 | |
On the south coast of Wales, I've been discovering | 0:52:08 | 0:52:11 | |
the story of the Welsh Great Escape. | 0:52:11 | 0:52:14 | |
During the Second World War, 70 German prisoners | 0:52:14 | 0:52:17 | |
fooled their guards by digging a tunnel | 0:52:17 | 0:52:20 | |
out of their rural prison camp. | 0:52:20 | 0:52:23 | |
For the first time in almost 70 years, | 0:52:23 | 0:52:25 | |
we're going to bring the escape tunnel back to life | 0:52:25 | 0:52:29 | |
with the help of Nick Russell, a 3D imaging expert. | 0:52:29 | 0:52:32 | |
We're hoping to reveal new secrets of this incredible prison break | 0:52:32 | 0:52:36 | |
but before the tunnel's ready to be scanned, there's a chance for me | 0:52:36 | 0:52:40 | |
to meet someone who remembers the story very well and with good reason. | 0:52:40 | 0:52:44 | |
She helped detain the final fugitives. | 0:52:44 | 0:52:47 | |
'Elaine Jones was 18 at the time.' | 0:52:47 | 0:52:50 | |
Tell me exactly what happened, that Saturday night. | 0:52:51 | 0:52:55 | |
Well, as usual, we were sitting, | 0:52:55 | 0:52:56 | |
listening to the Nine O'Clock News and waiting for the play to start. | 0:52:56 | 0:53:00 | |
-NEWSREEL: -This is the BBC Home Service. Here is the news... | 0:53:00 | 0:53:04 | |
We heard them announce on the news that the last three German prisoners | 0:53:04 | 0:53:09 | |
were still at large. | 0:53:09 | 0:53:11 | |
Before the news bulletin finished, | 0:53:11 | 0:53:13 | |
there was a knock on the door. My mother thought that someone | 0:53:13 | 0:53:16 | |
had come to ask for something from the shop but next minute, | 0:53:16 | 0:53:19 | |
the three Germans walked into the room with the farmer who had | 0:53:19 | 0:53:22 | |
met them on the mountain road. | 0:53:22 | 0:53:24 | |
Elaine's mother, the local postmistress, | 0:53:24 | 0:53:26 | |
phoned the local police while the farmer set off to get help. | 0:53:26 | 0:53:30 | |
They were obviously three very cold, tired men. | 0:53:30 | 0:53:34 | |
They'd been living rough | 0:53:34 | 0:53:35 | |
and eaten what they could forage in the fields. | 0:53:35 | 0:53:38 | |
'Amazingly, for an hour, the women guarded the enemy.' | 0:53:38 | 0:53:42 | |
When the police arrived, they thanked my mother profusely for her kindness | 0:53:42 | 0:53:47 | |
and shook hands with us before being handcuffed and marched out. | 0:53:47 | 0:53:51 | |
What's your great memory of it all? | 0:53:51 | 0:53:53 | |
Well, the fact that it happened to us as it did, I suppose, | 0:53:55 | 0:54:00 | |
because it's not the sort of thing that happened very often. | 0:54:00 | 0:54:04 | |
Back at the site of the prison camp, our excavations are going well. | 0:54:06 | 0:54:09 | |
The tunnel is still there. | 0:54:09 | 0:54:11 | |
Brett Exton, who's been studying the site for 12 years, | 0:54:11 | 0:54:15 | |
is itching to get in and have a look. | 0:54:15 | 0:54:18 | |
It's going to be an exciting moment for you, isn't it? | 0:54:18 | 0:54:20 | |
Oh, absolutely, I've waited all my life for a moment like this. | 0:54:20 | 0:54:24 | |
Oh, my word! | 0:54:30 | 0:54:32 | |
It's the first time he's ever seen inside. | 0:54:32 | 0:54:34 | |
Is it what you expected? | 0:54:36 | 0:54:38 | |
I'm almost speechless. It must go a good 30 feet down. | 0:54:38 | 0:54:41 | |
That is German technology for you, from the Second World War, isn't it? | 0:54:41 | 0:54:45 | |
Nick is anxious to get his 3D images but first how about this? | 0:54:47 | 0:54:51 | |
Well, Nick, you're a man who appreciates technology. | 0:54:53 | 0:54:55 | |
Just before you start your 3D experiments, what do you reckon to this? | 0:54:55 | 0:54:59 | |
It's something I've brought along and I think it could give us | 0:54:59 | 0:55:02 | |
a bit of tunnel vision. | 0:55:02 | 0:55:04 | |
-Is it working, Nick? -It's fallen over. | 0:55:12 | 0:55:15 | |
JOHN LAUGHS | 0:55:15 | 0:55:16 | |
Oh, no! | 0:55:16 | 0:55:17 | |
So much for my bright idea but now it's Nick's turn. | 0:55:17 | 0:55:22 | |
It's time for the lasers. | 0:55:22 | 0:55:24 | |
I'm going to go down the hole, Dave, | 0:55:24 | 0:55:26 | |
if you can pass me the laser scanner, once I'm in position. | 0:55:26 | 0:55:29 | |
The scanner fires invisible lasers up the tunnel | 0:55:29 | 0:55:33 | |
and before long, the first images are coming together. | 0:55:33 | 0:55:37 | |
BEEPING | 0:55:37 | 0:55:38 | |
That is pretty impressive, isn't it? | 0:55:39 | 0:55:41 | |
Because of the way the scanner operates, | 0:55:41 | 0:55:44 | |
there's no darkness. | 0:55:44 | 0:55:45 | |
We can see absolutely everything in the tunnel, | 0:55:45 | 0:55:47 | |
so you can see the detail of those pit props and every little stone | 0:55:47 | 0:55:51 | |
and then, right at the back, you can see where a bit of the roof | 0:55:51 | 0:55:54 | |
has come down but it does tantalisingly seem to continue. | 0:55:54 | 0:55:58 | |
-Is there any trace of a second tunnel? -There's just one tunnel. | 0:55:58 | 0:56:02 | |
It does curve around a bit to the right at the end. | 0:56:02 | 0:56:05 | |
'Brett's search for another tunnel will have to continue.' | 0:56:05 | 0:56:08 | |
So this is just your preliminary data, isn't it, Nick? | 0:56:08 | 0:56:11 | |
I look forward to seeing the finished product. | 0:56:11 | 0:56:14 | |
And a couple of days later, the final 3D model is ready | 0:56:16 | 0:56:19 | |
and here it is now exclusively on Countryfile. | 0:56:19 | 0:56:23 | |
The tunnel reveals its secrets in great detail for the first time | 0:56:23 | 0:56:27 | |
since those 70 men scrambled through it in 1945 | 0:56:27 | 0:56:31 | |
and made history in the Welsh Great Escape. | 0:56:31 | 0:56:34 | |
-Well, what a story that is. -Isn't it, yeah? Fantastic. | 0:56:42 | 0:56:45 | |
And to think that when they escaped, | 0:56:45 | 0:56:47 | |
they could well have been running over all of these dunes. | 0:56:47 | 0:56:50 | |
-Just like you now! -I don't suppose you fancy recreating that bit? | 0:56:50 | 0:56:53 | |
No, I don't! But what is wonderful, I think, | 0:56:53 | 0:56:56 | |
is that we can use 3D technology now | 0:56:56 | 0:56:58 | |
to recreate those events of so long ago. | 0:56:58 | 0:57:00 | |
And it's a lovely way to end the programme | 0:57:00 | 0:57:02 | |
because that is all we've got time for this week | 0:57:02 | 0:57:04 | |
because next week we're going to be in the Yorkshire Dales, | 0:57:04 | 0:57:08 | |
trying to recreate authentic Wensleydale cheese. | 0:57:08 | 0:57:10 | |
-Hope you can join us then. -Bye for now. -Bye-bye. | 0:57:10 | 0:57:13 | |
