00:28A
00:29A reedbed in Somerset and dragonflies glint in the early morning sun.
00:38They won't take to the air until their wings are dry.
00:49Others have spent the night in large communal roosts.
00:54And as the day warms, they slowly climb up the reeds.
01:01Until finally, they're ready.
01:10All dragonflies begin their lives as larvae in fresh water
01:15before emerging as adults for their summer in the sun.
01:23Their flying agility is second to none.
01:33Or almost none.
01:38A hobby.
01:44These small birds of prey spend the winter in Africa
01:48and time their arrival in Britain
01:50to take advantage of this mass emergence of dragonflies.
02:01But things don't always go their way.
02:10The dragonflies can dodge with the flick of their wings.
02:27So the hobbies turn their attention to the female dragonflies,
02:32who are busy laying their eggs on the water's surface.
02:45The hobby's come in low and fast.
02:49The hobby's come in low and fast.
03:06This summer spectacle is totally dependent on one thing.
03:13Fresh water.
03:28Here in Britain and Ireland, we have some of the loveliest rivers and lakes in the world.
03:36From the lochs of Scotland to the waterfalls of Wales.
03:42From the great Shannon River in Ireland to small intimate chalk streams like this one in Wiltshire.
03:52But today, less than half of our rivers and lakes are in good health for nature.
03:56In this episode, we will reveal the crucial role that fresh water plays in supporting wildlife of all kinds.
04:09Fresh water is the lifeblood of the natural world.
04:15We have over 150,000 miles of rivers in the British Isles.
04:20They flow through every landscape, connecting all our wildlife.
04:30The water's journey starts at the top of the mountains.
04:54Rivers shape the landscape.
05:00They feed and water a multitude of different rivers.
05:04Different habitats.
05:07And finally, they enter the sea.
05:11And here in Northern Scotland, ghostly shadows have gathered where they do so.
05:21Atlantic salmon.
05:27After four years at sea, they've returned to the very river where they were hatched.
05:34It's spring, and they will spend the next six months battling their way up river to their breeding ground.
05:43But their great numbers have attracted attention.
05:55Bottlenose dolphins.
06:00A pod has gathered at the mouth of the river Ness.
06:04The tide is rising, and this is when the fish will try to enter the river itself.
06:19The salmon may be over a meter long and difficult to swallow.
06:24But these intelligent hunters still find time to play with their food.
06:44The salmon that get past them swim through a hazy mix of waters, and at last reach the fresh.
06:57From this point on, they are freshwater fish.
07:05Their bodies change inside and out.
07:11Their sea-fresh silvery sheen dulls to a darker hue that camouflages them against the riverbed.
07:21But the river is low.
07:23Until there's rain, they can go no further.
07:27They may be stuck here for months.
07:30As they will no longer eat, conserving energy is key.
07:42Rain at last.
07:49Rain at last.
07:50The river rises so the fish can start moving further upstream.
08:01The rapids of the Lowlands are passed without much effort.
08:11But things soon start to get more difficult.
08:22The salmon push on ever higher before reaching the most demanding test on their journey.
08:33These falls are three meters high and right at the fish's limits.
08:41They gather beneath the thundering water.
08:48Some may practice leaps, assessing the best angles of attack.
08:59Finally the time is right.
09:06And now the real leaping begins.
09:16They use the white water to slingshot their bodies into the air.
09:23No other fish can clear waterfalls as high as this one.
09:31Some crash into the rocks.
09:34The thud of their muscular bodies audible even above the roar of the water.
09:43Every year fewer and fewer get to this point in the river.
09:49Returning salmon numbers have fallen by 70% in just 25 years.
10:00But those that have got here push on with astonishing vigor.
10:16By late autumn the survivors finally arrive at their traditional spawning grounds.
10:25It's time at last to breed.
10:31The females get straight to work digging their reds, shallow depressions in the gravel.
10:39This is where they will lay their eggs.
10:43The males, in full spawning colors and with newly developed hooked jaws, wait close by.
11:00A female releases thousands of eggs.
11:05And one of the males fertilizes them as they emerge.
11:14It's the culmination of a journey against the flow and the odds.
11:23The eggs will develop in the gravel throughout the winter and soon become tiny fry.
11:33Their heart beats visible through their translucent skin.
11:40The salmon's return will sustain the whole river ecosystem through the long winter months.
11:50But they need cold, clear, free-flowing water to thrive.
11:55And due to climate change, pollution and dams, all are in short supply.
12:03Atlantic salmon were once common across Britain and Ireland.
12:08But are now increasingly restricted to these remote northern rivers.
12:16At the current rate of decline, they may disappear from all our rivers in as little as 20 years' time.
12:25The grandchildren of these fish may be the last to make this astonishing journey.
12:37The rivers, having left the mountains, widen and slacken.
12:44In places, they enter lakes such as this loch in Perthshire.
12:53But here, something else may slow them.
13:00Beavers.
13:02400 years ago, they were hunted to extinction for their fur.
13:07But now they've been reintroduced to Scotland, and it hasn't taken them long to get established.
13:18Signs of their industry are easy to see.
13:28They're best known, perhaps, for their skill in building dams.
13:33And this family spends a lot of time making sure that theirs is in good shape.
13:47The dam has created a huge wetland.
13:55It's a beaver-built paradise that provides plenty of living space and unlimited access to food.
14:11At this time of year, branches on the move can only mean one thing.
14:18Newborn beaver kits.
14:24The kits will stay with their family for the first few years before setting out to find
14:30territories of their own.
14:36There are over 250 beaver territories in Scotland, and they're now being reintroduced into England
14:43and Wales.
14:52By slowing the river, the beavers create a rich habitat for a whole range of other species.
15:00Right to the top of the food chain, ospreys.
15:21Still clean water attracts all kinds of wildlife.
15:27On a heathland in Dorset, spiders' webs cover the bushes surrounding a pond.
15:36And one specialist species lives at the very edge of the water.
15:44A female raft spider.
15:47She's the size of your palm and a deadly assassin.
15:53She uses the surface of the water as her web and senses the presence of prey from its vibrations.
16:14A good start, but it's mating season, and she'll need much more food if she's going to breed.
16:24A pond skater could be a good snack, but it's not easily caught.
16:30A pond skater could be a good snack, and she'll need much more food if she's going to be a
17:00good snack, and she'll need much more food if she's going to be a good snack.
17:10Such a small meal is barely worth the effort.
17:17But she can also hunt under the surface.
17:24There are much bigger meals to be had down here.
17:30The lava of a diving beetle, itself a ferocious predator.
17:41But it has to come to the surface to breathe, through a tube in its rear.
17:48And that brings it within striking range of the spider.
17:57The lava of a diving beetle, itself a ferocious predator.
18:22The lava of a diving beetle, itself a ferocious predator.
18:29Now, she has the energy needed to find a mate.
18:36She lays down a thread of silk, laced with perfume.
18:46Before returning to her favorite spot.
18:51And it's not long before another raft spider picks up the trail.
18:57A male.
19:00He has a pair of large boxing glove-like organs called pedipalps, in which he stores his sperm.
19:09And this is what he's been looking for.
19:11A thread of silk that leads straight to her.
19:18Once close, he taps the water surface, to signal that he's about to approach.
19:27He's no bigger than her last meal.
19:31A wrong move now, and he could become dessert.
19:38She seems receptive.
19:42It's now or never.
19:54Carefully does it.
19:55Carefully does it.
19:55Carefully does it.
20:01They mate, in a tangle of legs.
20:04And he uses one of his calps to transfer his sperm into a sack in her body, where she will
20:11keep it until she's ready to use it.
20:15The male then beats a hasty retreat
20:19before she makes a meal of him, too.
20:29As rivers reach the middle stages of their journey,
20:33they increase in both size and power.
20:39And it is their force over millennia
20:42that has shaped our landscape.
20:49In limestone country,
20:51the freshwater carves its way underground.
20:59Britain and Ireland contain thousands of miles of caves,
21:03including these in County Cavern.
21:11The dripping water builds stalactites and stalagmites,
21:17like these teeth coming together in a rocky grimace.
21:24Over centuries, it can create all kinds of pillars and curtains.
21:30Yet even here, there is life.
21:35Thorbenton's bats roost in caves during the day.
21:40And as night falls, they head out to feed.
21:48Ghostly shapes appear over a starlit river.
21:56The bats navigate by sending out echo-location calls,
22:01which we can watch in operation
22:02if we slow down both sound and picture.
22:12It's soon clear why Thorbenton's bats are also called water bats.
22:20They patrol the river,
22:21searching for tiny movements on the surface of the slow-moving water.
22:26They use the echoes from their calls to lock on to their prey.
22:38And then skim it from the surface.
22:55Weighing about eight grams,
22:57these little bats can nearly double their body weight
22:59in a single night's hunting.
23:03And on this autumn night,
23:05the males in particular need all the energy they can get.
23:17A Thorbenton's bat circles in a woodland glade.
23:23And it's soon joined by others
23:25emerging from a cave at the base of a tree.
23:32Amongst their navigational cliques,
23:34there's a different sound.
23:40They're calling to one another.
23:48As their numbers increase,
23:50so do their calls.
23:55Soon, other species arrive,
23:57including natterers and brown long-haired bats.
24:03There can be up to ten species at any one time,
24:06whirling around in this pitch-black arena.
24:15This is a display ground,
24:17where male bats compete to impress the females.
24:36Some of these bats have traveled over 40 miles to be here.
24:52around midnight,
24:53the bats disappear back into the caves below,
24:57where they will soon settle down to hibernate.
25:12spring brings the end of hibernation for another animal.
25:19A common toad.
25:23This is a female.
25:27Common toads need fresh water,
25:30in which to lay their eggs.
25:32So she must find a pond.
25:35And that can involve a journey of several miles,
25:38which is full of obstacles and dangers.
25:45She's not the only one on the move tonight.
25:50Male toads are also about.
25:56They're in search of females.
25:58And when this male finds one,
26:00he locks on tight.
26:06But his rivals have the same idea.
26:10And then it's a wet-leg wrestling match,
26:13to stay in prime position.
26:22The competition is seen off.
26:24And the bonus is a free ride.
26:28But the biggest challenge lies ahead.
26:35Roads now cross many of the toads'
26:38traditional migration routes.
26:40And tens of thousands are killed every year.
26:44The toads are killed every year.
26:50The toads are killed every year.
26:52And the toads are killed every year.
26:56And the toad are killed every year.
26:58And the toads are killed every year.
27:00And the toad is killed every year.
27:03Be a cat.
27:07Made it.
27:11With toad numbers down by two-thirds in the past thirty years,
27:15we ought to be careful on warm, wet nights in March.
27:25At dawn, the female and her hitchhiker reach the end of their journey, the very
27:34pond in which she hatched as a tadpole. They get straight down to business and
27:43the female produces thousands of eggs in long links of spawn.
27:54The male, if he holds on tight, will fertilize them all.
28:02A few months later and summer is here.
28:08These tiny toadlets are now ready for their next stage.
28:15They must head for dry land.
28:20They will spend most of their adult lives in the woods from which their mother emerged.
28:29But to get there, they must cross a killing zone.
28:40Haunted by giant leeches.
28:51Some are 15 centimeters long.
28:57And they have an appetite for baby toads.
29:05They hunt using a keen sense of smell and five pairs of eyes.
29:24The toadlets must keep going if they want to reach the woods.
29:37If they're not quick enough, their fate is grim.
29:45Consumed whole.
29:56The leeches can grab with either end of their body.
30:01And three sets of teeth.
30:09Once caught, a toadlet has no escape.
30:31But for everyone that is taken, hundreds make it to the safety of the woods.
30:39For most of these toadlets, it's a horror story with a happy end.
30:50In the British Isles, we have one of the world's rarest and most beautiful freshwater habitats.
30:59Chalk streams.
31:03Only around 200 exist in the world, and over three quarters of those flow here in England.
31:14A reliable flow of cool, mineral-rich water bubbles up through the chalk below,
31:20and supports a rich freshwater community.
31:49On the riverbed, something stirs.
31:57This young insect has spent the last two years buried in the gravel.
32:03With strong front legs, feathery gills, and a streamlined body,
32:07it's excellently adapted to life underwater.
32:14But it's late May, and everything is about to change.
32:24Even breaking through the surface is a challenge when you're just two centimeters long.
32:36Finally, as its wings unfurl, the little creature starts a new life as an adult.
32:42A male mayfly.
32:48He now has just a few short days to live, so he quickly prepares for his first flight.
32:57And the sooner the better.
33:03The fish below are the first to notice this springtime bonanza.
33:17And it's not long before those above water also get their eye in.
33:23He needs to get airborne.
33:32But it's out of the flying pan and into the fire.
33:43At least the mayfly have the advantage of great numbers.
33:48In just a week, more than a million will emerge from this stretch of river alone.
33:56And the first thing the male does is head for the riverbank.
34:03Unique among insects, mayfly undergo a second adult molt before they're fully mature.
34:10His whole life has been building to this moment.
34:16And finally, he's ready.
34:22He flies high above the river and joins the mating dance.
34:35Rising and falling with the other males, he spreads out his tail, showing off his aerial prowess.
35:00It's all for the benefit of the females, who are now emerging from the water below.
35:08Soon, the riverbank is alive with mating pairs.
35:22Each male will continue to dance until he dies of exhaustion.
35:40A small hole in the riverbank.
35:44Home to one of the most secretive of the river's residents.
35:55A shrew.
35:58This one, a female, is pretty small about the size of your thumb.
36:06Being small means she loses heat quickly and must eat almost constantly.
36:12Three hours without food could be fatal.
36:19So when supplies on the bank get low, she must find food elsewhere.
36:29She's a water shrew.
36:33She's somewhat reluctant at first.
36:36Underwater, she will lose heat even faster.
36:39But needs must.
36:41So when she does take the plunge, she works at great speed.
36:57In real time, it's impossible to see what's going on.
37:01But slowing things down reveals how marvelously adapted she is to the underwater world.
37:11Stiff hairs on her feet act like flippers.
37:16And others on her tail turn it into a rudder.
37:24She swims with her eyes closed, fanning out her whiskers to help her sense her prey.
37:35And most remarkably, she can detect smells down here.
37:44She lets out tiny bubbles of air to pick up scent particles in the water.
37:52It's known as bubble sniffing.
38:00But using this technique means she quickly runs out of air.
38:10This time, everything comes together.
38:16A dragonfly larva is a huge meal, but hard to subdue.
38:23It's time to use her final weapon.
38:28Water shrews are the only mammal in Britain with venomous saliva.
38:37All wildlife is dependent, to some extent, on fresh water.
38:42But here in England, every single river is polluted.
38:49Runoff from farming and dumping of human waste causes algae to bloom.
38:55This reduces oxygen, chokes the plants and degrades the rivers on which our wildlife depends.
39:16As rivers approach the end of their journeys, they slow and beds of reeds are able to take root.
39:27Here in Suffolk, it's late winter.
39:41Red deer.
39:46This huge area is a little known winter refuge for Britain's largest land mammal.
40:00The paths the deer create make gaps in the reeds.
40:08And on the open water, great-crested grebes.
40:14It may be early in the year, but their mating dance is already well underway.
40:23As a prologue, the birds shake their heads, showing off their plumage and preening to make sure their feathers are
40:31in tip-top condition.
40:35Costumes ready, Act 1 reaffirms any bonds that were made in previous years.
40:43Single birds call for a partner, before adopting a posture known as the cat display.
40:57It's an invitation for a duet.
41:12It seems to have been accepted.
41:15The pair are falling into step.
41:24But they are interrupted by a rival.
41:29Another male is looking for a partner and starts a shark-beaked argument.
42:01This guy alwaysoppens his life.
42:04that ends well, the rival is seen off,
42:08and the pair begin the final act of their duet, the weed dance.
42:25These complex displays create a bond between the pair,
42:30which will keep the two together as they raise their young.
42:38A few weeks later, and the first chick appears,
42:43shortly followed by the second.
42:48Both parents care for the chicks,
42:50taking turns to babysit while the other finds food.
42:59They even take feathers from their own backs
43:02and feed them to the chicks to protect tiny tummies from sharp fish bones.
43:10This extraordinary caring behaviour depends on the firm bonds that were made back in the spring.
43:20Greeds that dance together stay together.
43:27We have lost huge areas of reed beds over the years,
43:31drained for agriculture,
43:34but recent conservation efforts have shown that they can be restored remarkably quickly.
43:48The journey of fresh water ends when rivers reach the sea.
43:53Here, they may create vast mudflats.
43:56Together, they constitute over 2,000 square miles of our coastline.
44:03From above, they look lifeless.
44:07But they are full of opportunities.
44:14It's low tide, and there's plenty of space to forage.
44:24Every winter, millions of migratory birds from all over the northern hemisphere
44:29arrive in our estuaries to refuel.
44:37But the tide has turned, and the sea starts rushing in.
44:46The restaurant is closing, and the birds are driven from the mud.
44:54The most common birds here, not, take to the air en masse.
45:20Watching from above, a peregrine.
45:25He may be the fastest animal on the planet,
45:28but it won't be rushed.
45:34It surveys the flock from on high.
45:41And then, tucks in its wings,
45:44and dives at speeds of up to 200 miles an hour.
45:57The lot bunched tightly together.
46:01There's safety in the middle of the flock.
46:09It's difficult for the peregrine to select an individual bird.
46:15So it changes its tactics.
46:21Coming in low, it's easier to pick out an individual knot.
46:30Using the hard-packed mud as a weapon,
46:33it drives its victim into the ground.
46:46The knot is left with a damaged wing.
46:53But the peregrine will be back.
47:03Every winter, peregrines come to the coasts of the British Isles
47:08to take advantage of this seasonal bounty.
47:38The flock is reduced by one.
47:41The flock is reduced by one.
47:42But when you're 100,000 strong,
47:45that is a small price to pay.
47:52With the tide now at its highest,
47:56the birds settle down to rest.
48:01The position of the British Isles on the planet
48:05makes our estuaries globally important.
48:13They provide vital refueling stations
48:16for migratory birds from different parts of the globe.
48:26On its journey from the mountains to the sea,
48:29fresh water has fed and refreshed the natural world.
48:34It's the lifeblood of our wild isles.
48:50One of the greatest spectacles in the British Isles
48:53is the migration of Atlantic salmon.
49:00Despite the numbers being in free fall,
49:02the freshwater team were determined to find new ways
49:06to film these astonishing fish.
49:09The story begins near Inverness in northeast Scotland.
49:14Every summer,
49:16a pod of bottlenose dolphins gather just offshore.
49:19drawn here by the salmon.
49:22They come along a very narrow channel
49:24that runs just off the beach here.
49:28The dolphins have clucked that
49:30and they can basically just sit
49:32off the point in this deep channel
49:33and wait for the fish to come
49:35and just pick them off.
49:38The dolphins only hunt for about an hour.
49:41So the crew get into position early.
49:44But they're not the only ones.
49:47Crowds of people soon join
49:49to see the action.
49:53This is one of the best places in the world
49:55to see this behavior so close to shore.
50:00The next stage for the salmon
50:01is to swim up into the freshwater.
50:05Here, they're nervous and extremely wary of people.
50:09So it's almost impossible to film
50:11using standard techniques.
50:14But the crew have a trick up their sleeve.
50:17An underwater drone.
50:20This is another what could possibly go wrong moment.
50:22This is another what could possibly go wrong moment.
50:49Can I find a screw?
50:52Whoa, whoa, whoa!
50:53What?
50:54Oh, you beauty!
50:57With the sub back up and running,
50:59the team begin to record the salmon's underwater world.
51:03A glimpse into this extraordinary migration
51:07that few people have seen.
51:09One of the most beautiful things I've ever seen.
51:13Absolutely mesmerizing.
51:17The next and greatest challenge for the salmon
51:20is ascending the three-meter waterfall.
51:25Filming the salmon leaping here
51:27is the team's biggest challenge, too.
51:31For the first shot,
51:33the camera needs to be positioned
51:34directly above the falls.
51:38That means getting more than
51:39a hundred kilograms of kits into position
51:42four meters above the roaring water.
51:45The fish still aren't jumping at the moment
51:47but that's fine
51:47because they're waiting for the water to drop
51:49and hopefully in the next few hours
51:50they'll start to jump
51:51and once they do start
51:52there should be repeated attempts at this.
51:55The new camera position pays off
51:57The team filmed the salmon
51:59leaping head-on for the first time.
52:03But there's one angle
52:05that Taff has been dreaming about for years.
52:09We're going to try the dream shot.
52:12The fish are actually
52:13leaving the water from below.
52:16OK, so this is it.
52:18The moment of truth.
52:19OK.
52:21Yeah, yeah, I'm getting it.
52:22Yeah.
52:24Away she goes.
52:25Below the falls,
52:27the water flow is at its highest
52:30putting the slug and Taff's skills
52:32under serious pressure.
52:35You know, probably nobody's
52:36watched this behavior
52:37but they nervously go and look at it
52:40and then they go around
52:42and they do a little test
52:43and then they come back
52:44and then they go for it.
52:46That's the amazing.
52:47All these years filming salmon
52:48it's the first time I've seen this.
52:50This was the first time
52:52salmon had been filmed
52:53leaping from underwater.
53:00Finally, just a few salmon
53:02make it to the top of the river.
53:05The place in the river
53:06where they themselves hatched
53:08there's young salmon.
53:11When breeding
53:12they're at their most sensitive
53:15and getting these intimate moments
53:17needs some serious dedication.
53:20I'll film every day
53:21other than Christmas Day
53:22and Boxing Day
53:23and I would film on Christmas Day
53:25if my wife would let me
53:26but she does not let me do that.
53:27I've been doing this
53:28for about five years
53:29so we know when and where
53:30the fish are going to spawn now
53:31so that's the key thing
53:33is knowing where they are.
53:35With spawning complete
53:36the salmon's journey is done
53:40but for the crew
53:41there's one final part
53:42of the story
53:44and they've waited
53:45three years
53:46for the perfect conditions.
53:54Not very elegant slide
53:56but this is a really cool slide.
53:59An otter slide
54:01a clear indication
54:03there's one nearby.
54:06Otters are usually
54:07very elusive
54:08during the day.
54:09These cold conditions
54:11gave Raymond his chance.
54:13See the otter
54:14further down river
54:15it's just come out
54:16onto the ice shelf
54:17on the side there.
54:19It's only staying for like
54:20three or four seconds
54:21and it's back in the water.
54:23It's hard work this.
54:29At the very end
54:31of their journey
54:31the salmon
54:32the salmon not only provide
54:33a much-needed meal
54:34for this otter
54:35their dying bodies
54:37will provide
54:38essential nutrients
54:39enriching the upper reaches
54:41of our rivers.
54:43Salmon once swam
54:45in rivers throughout
54:46the British Isles
54:47in huge numbers
54:48but in the last
54:49twenty-five years
54:50the number returning
54:51from the sea
54:52has dropped
54:53by seventy percent.
54:55In England and Wales
54:56the situation is critical
54:58with over ninety percent
55:00of salmon river populations
55:01at risk of collapse.
55:03And we fill them in all
55:05these different places
55:05in all these different
55:06environments.
55:07It's kind of really
55:07brought home that
55:09you know,
55:10we really are
55:10messing with them
55:11every step of the way.
55:13Our man-made barriers
55:15block their migration
55:16routes
55:18sewage from towns
55:19and cities
55:20and agricultural
55:21runoff from farms
55:23pollute our rivers
55:25making the salmon
55:26more susceptible
55:27to disease
55:28On top of all this
55:30climate change
55:31presents them
55:32with even greater
55:33challenges
55:33They need cold,
55:35clean water
55:36that's what they need
55:37and a lot of areas
55:38they're not getting that.
55:39Anything over
55:40twenty-three degrees
55:41they stop feeding
55:42and anything over
55:43thirty they die
55:44within minutes.
55:46We need to look at
55:47trying to manage
55:48those water temperatures
55:49and if we can bring
55:50that habitat back
55:51in effect
55:52rewild those
55:53bits of rivers
55:53to put them to
55:54how they should
55:55historically have been
55:56it's going to have
55:56a knock-on benefit
55:57for all the species
55:59that use the ecosystem.
56:02Salmon are resilient
56:03animals.
56:05If we can improve
56:06the quality
56:07of our fresh water
56:08remove barriers
56:10to its flow
56:10and better manage
56:12the challenges
56:13at sea
56:15Salmon could
56:16once more
56:17become abundant
