Some animals are notoriously difficult to see.

0:00:020:00:04

Can you see it? You don't know what you're looking at, do you?!

0:00:040:00:08

Many only come out at night...

0:00:080:00:10

No, we can't come in here now.

0:00:100:00:12

Others hide in holes or up trees...

0:00:120:00:14

It's a bit deeper there, Gordon. Gordon!

0:00:140:00:18

And some just like to keep their heads down...

0:00:180:00:21

I'm checking whether this is one woozle or two weasels or whatever Christopher Robin said.

0:00:210:00:25

But this doesn't deter the devoted and plucky folk who make up Britain's secret wild army.

0:00:250:00:32

Four animals, four amateur naturalists, four inspiring stories.

0:00:320:00:38

BIRDSONG # Dee, de-de, dee, dee... #

0:01:010:01:03

Gordon, what have we got singing over there at the moment? Willow warbler, or a black cap?

0:01:030:01:08

It takes more than a spot of rain to put these three intrepid gentlemen off their regular wildlife mission.

0:01:080:01:13

We were waiting for that.

0:01:130:01:15

Think there was a stitchwort there, and a campion...

0:01:150:01:18

In the depths of a Devonshire wood are 50 nest boxes,

0:01:180:01:22

all carefully mapped and meticulously numbered, and all of them need inspecting.

0:01:220:01:27

This is more like jungle exploration!

0:01:290:01:32

Leading this dedicated band is retired biology teacher Tom Maddock.

0:01:350:01:39

Where is it?

0:01:390:01:41

Oh, there we are.

0:01:410:01:43

Right.

0:01:430:01:44

This is going on this stone, then I can open the box.

0:01:450:01:49

I always think this is like Christmas, cos you never quite know what you're gonna find.

0:01:490:01:54

And, in fact, what we've got is a brood of blue tits.

0:01:540:01:58

That was box number one and 49 to go!

0:01:580:02:02

Something's been in there, a slug...?

0:02:040:02:06

Finding a nest of blue tits might be treasure enough for some,

0:02:060:02:09

but Tom and his team are after something much more unusual.

0:02:090:02:14

I can see, um, shreds of plant material, so I'm gonna take this one down.

0:02:140:02:20

Ten or 15, Gordon?

0:02:200:02:22

Oh! Ha-ha! Now...

0:02:330:02:35

Wonderful, isn't it? Look at that. Isn't that brilliant?

0:02:370:02:40

What we have here is a torpid dormouse. There we are.

0:02:400:02:44

This is the reason for our quest.

0:02:480:02:51

It's a delightful find, but it's not just for personal pleasure.

0:02:510:02:57

Tom and his friends are part of the National Dormouse Monitoring scheme,

0:02:570:03:01

volunteers who are qualified to handle and study this rare and endearing mammal.

0:03:010:03:05

No other rodent spends half its life sleeping.

0:03:050:03:08

These will sleep for six months of the year, and they will normally

0:03:080:03:13

start to wake up about midday, they're late risers.

0:03:130:03:18

He doesn't want to show me his special parts. Hee-hee!

0:03:180:03:21

He's very coy, this one.

0:03:220:03:23

I would say...that we have...

0:03:250:03:28

We have a male here.

0:03:300:03:31

You can see a tiny penis.

0:03:310:03:34

So what I'm gonna do next is weigh the animal...

0:03:350:03:38

This one's 19.8.

0:03:410:03:43

19.8.

0:03:430:03:45

A good weight.

0:03:450:03:48

Tom's love of wildlife is part of a great British tradition.

0:03:500:03:54

For centuries, like-minded amateur naturalists have watched and recorded everything that moves

0:03:540:03:59

and grows, making Britain the best-studied place on Earth.

0:03:590:04:03

Like many others, Tom was first inspired when he was just a boy,

0:04:040:04:08

and it's all down to this man, HG Hurrell.

0:04:080:04:12

Oh, Lord, for what we are about to receive, make us truly thankful, for Christ's sake. Amen.

0:04:120:04:18

Hurrell's family is a family of naturalists.

0:04:180:04:22

His younger son, Kenneth, his daughter Elaine, who runs a section of the Bristol Naturalists Society.

0:04:220:04:27

Their mutual love of wildlife forms a deep family bond of understanding.

0:04:270:04:31

Hurrell was himself an amateur naturalist.

0:04:310:04:34

His knowledge and interest was infectious.

0:04:340:04:36

HG came to school once and showed films at school.

0:04:360:04:40

I was trapped by that, really.

0:04:400:04:43

And he was to me something of an idol.

0:04:430:04:46

And I thought, "This is what natural history's all about."

0:04:460:04:50

HG died in 1981, but his daughter Elaine, now in her 70s, is still a good friend, and mentor, to Tom.

0:04:520:05:00

Hello, Elaine.

0:05:000:05:01

Hello, Tom. Come inside.

0:05:010:05:03

Right, we've managed to complete the whole check. There's our first dormouse,

0:05:030:05:08

-in number nine, nicely torpid, so that made for ease of handling.

-Oh, really?

0:05:080:05:12

-Yeah, so that was good.

-Yeah.

0:05:120:05:14

So that was that one.

0:05:140:05:16

It means a lot to Elaine that Tom is carrying on the dormouse work

0:05:160:05:20

she and her father started back in the 1950s.

0:05:200:05:23

We've got three in here.

0:05:230:05:25

I suppose my father was very interested in recording anyway in all kinds of observations.

0:05:250:05:30

His diary was kept for something like 60 years.

0:05:300:05:34

You know, it's extremely interesting now to read them, of course,

0:05:360:05:41

because he said, "I saw a beautiful mouse tonight, absolutely perfect,

0:05:410:05:46

"lovely tail, and I had a really good view of it."

0:05:460:05:49

And that's what we were doing, was watching for dormice behaving naturally in the wild.

0:05:490:05:56

Through their dedicated dormice watching, the amateur naturalists made a significant discovery.

0:05:560:06:03

"Late October, I happened to walk under a large hazel bush

0:06:030:06:07

"about 100 yards from our house,

0:06:070:06:09

"and found that other creatures besides squirrels had shown interest in the nuts.

0:06:090:06:14

"I picked up over 30 shells from which the kernels had been extracted through a hole at one side.

0:06:140:06:20

"This could not possibly be the work of squirrels.

0:06:200:06:24

"It appeared even at a glance to be the work of mice."

0:06:240:06:28

They were very good carpenters, dormice, I always remember that.

0:06:280:06:31

And they have a tiny chiselling effect on the edge of the hole.

0:06:310:06:37

The discovery of these distinctive calling cards

0:06:370:06:40

mean that you no longer have to see dormice to know they're there.

0:06:400:06:44

So Elaine was asked by the Mammal Society to do a survey.

0:06:450:06:48

For the first time, it was possible to produce a dormouse map of Britain.

0:06:480:06:54

The survey was, when you look back on it, was great fun.

0:06:540:06:57

It was hard work as well, but...

0:06:570:07:00

Jumping in the bramble bushes to look for nuts!

0:07:000:07:04

Today Tom is building on that knowledge.

0:07:040:07:07

Ah, you can see its front feet quite well...

0:07:070:07:10

Ah, it's on the move, I'm gonna have a job to sex this one, I think.

0:07:100:07:14

The total weight now is 55.3...

0:07:140:07:15

So that's a gram or so more than that female.

0:07:170:07:21

All this weighing, sexing and measuring goes to the People's Trust For Endangered Animals.

0:07:210:07:26

Sadly, dormice are on their list.

0:07:260:07:29

It's an amazing creature that has been in this country for

0:07:290:07:33

thousands of years, and up till, well, perhaps maybe...only about

0:07:330:07:41

50 years ago, we started to get to grips

0:07:410:07:44

with how this animal behaved, and what it was doing,

0:07:440:07:48

and because we now have more data about dormice

0:07:480:07:52

than maybe any other small mammal in this country,

0:07:520:07:57

any effects of global warming might first

0:07:570:07:59

appear in a creature like this, which has a completely different strategy from all the others.

0:07:590:08:04

It's vital that amateurs like these keep an eye on animals like dormice,

0:08:040:08:10

and it's lucky their sleeping habits allow us to see them easily.

0:08:100:08:13

But hidden in a wooded valley in Gloucestershire, other mammals

0:08:130:08:18

have chosen a less accessible, but much grander place for a bedroom.

0:08:180:08:22

Woodchester estate was bought by William Leigh in 1845.

0:08:250:08:28

He commissioned architects to build a forbidding gothic mansion, but the house was never finished.

0:08:280:08:34

It was mysteriously abandoned 23 years later.

0:08:340:08:38

Visitors have reported sightings of a headless horseman, and even a floating coffin!

0:08:440:08:49

No wonder it has the reputation of being one of the most haunted houses in Britain!

0:08:520:08:57

And up in the ancient rafters are some residents who certainly add

0:08:590:09:02

a frisson to the place - but to see them, you have to wait until after dark.

0:09:020:09:07

SQUEAKING

0:09:110:09:13

The horseshoe bats are famous for their noses.

0:09:170:09:21

It just blasts its echo-location sounds through its nostrils

0:09:210:09:26

into what is like a parabolic reflector, it's like a torch beam.

0:09:260:09:30

Then they get these beautifully focused beams of ultrasound,

0:09:300:09:34

which make them incredibly good at distinguishing fine detail.

0:09:340:09:39

They can discriminate between different types of insects

0:09:410:09:44

while there are flying, in ways that are very difficult to understand.

0:09:440:09:48

Despite being the largest and longest-living bat in Britain,

0:09:480:09:53

its numbers have plummeted by 90% over the last 100 years,

0:09:530:09:58

making it one of our rarest species.

0:09:580:10:01

But this is the first file I had to do my project.

0:10:010:10:05

We did basic descriptions of the habitat...

0:10:050:10:09

Roger Ransome was the ultimate schoolboy naturalist.

0:10:090:10:12

I started working on bats in 1956 as part of a school project.

0:10:120:10:17

I felt that this was a really good area to get into

0:10:190:10:22

because there was very little known about the natural history of bats.

0:10:220:10:25

It was known that bats live a long time.

0:10:250:10:27

They actually can live up to 40 years.

0:10:270:10:31

I got the art prize for Cheltenham Grammar School in the first year.

0:10:310:10:35

We had heard that there were lots of bats coming out of Woodchester mansion.

0:10:350:10:39

And we made an attempt to get in while we were at school.

0:10:390:10:45

The man who had the lease on the mansion wasn't too keen on sixth-formers wandering around,

0:10:450:10:51

and it wasn't until 1959 that I persuaded him that, really, I was an upright and honest person...

0:10:510:11:00

Roger's schoolboy persistence has continued for 51 years.

0:11:020:11:07

His study of the bats in Woodchester has been going on longer

0:11:070:11:11

than any study of any mammal in the whole world!

0:11:110:11:14

When I started, I was doing all the basic biometric measurements that I still do today.

0:11:140:11:21

We're now through something like 10 generations, it's just keeping it

0:11:210:11:26

going consistently for that period of time which makes it become valuable.

0:11:260:11:30

The computer says 107 bats went out.

0:11:350:11:38

Nowadays, the computer is the saving grace.

0:11:410:11:44

I could not process data without it.

0:11:440:11:46

That's where Michael, my grandson, comes in, cos he's my IT adviser.

0:11:470:11:51

Are yours coming out, Gemma?

0:11:540:11:56

We've only got three out so far.

0:11:560:11:58

Every week, Roger and his army of volunteers use a mass of technology to monitor the bats.

0:11:580:12:04

Ted and Gemma are...have swung the cameras around, so that they are counting the bats flying out to feed.

0:12:040:12:12

If the bats go out when it's very, very bright, we know they're diet-stressed.

0:12:120:12:17

If they go out when it's very dark, we know they've got plenty to eat, and they're fine.

0:12:170:12:22

This one...

0:12:220:12:24

Well, this is to look for

0:12:240:12:27

behaviour patterns between animals that we know are related to each other.

0:12:270:12:33

And the associations seem to be mainly between the females.

0:12:330:12:38

This is a female-dominated society,

0:12:380:12:41

er, and what we have is a series of matrilines,

0:12:410:12:46

lines of bats that go back to a single female.

0:12:460:12:51

And all together, we've got something like 15-17 matrilines in the colony, so it's a large number.

0:12:520:12:59

The more I find out, the more there is to find out.

0:12:590:13:02

The complexity of this animal is just utterly amazing.

0:13:020:13:05

It's been around 40 million years, and, er, we're pretty recent arrivals on the scene.

0:13:050:13:11

They have an incredibly complex social organisation,

0:13:110:13:16

vocal communications, which we're only just beginning to understand.

0:13:160:13:20

Right, so, I'm going through this hole...

0:13:200:13:22

But it's not all hi-tech, and you do need to stay in shape.

0:13:220:13:26

Once the bats have left the roost, Roger can get in.

0:13:280:13:31

Well, how else can you collect your weekly bat droppings?

0:13:310:13:36

This yellow sheet is beneath the attic space that we were looking at.

0:13:360:13:41

I'm gonna take them back to my house,

0:13:420:13:44

dry them all out, and then we'll treat them in solutions,

0:13:440:13:50

and we're left with the skeletons of the insects, which we can recognise under the microscope.

0:13:500:13:56

And all jolly good fun.

0:13:570:14:00

We do it week in, week out, and we see how the diet changes.

0:14:000:14:04

That's quite a lot, really, for one week.

0:14:040:14:07

They're feeding well at the moment.

0:14:070:14:09

The other thing we have to do is to check the state of our cameras.

0:14:090:14:14

Roger has contributed to 34 scientific papers.

0:14:140:14:17

And in 2002, he co-wrote the European Action Plan,

0:14:170:14:21

which gives better protection to greater horseshoe bats.

0:14:210:14:26

They do say scientists have their most productive work by the time they are 30 or 40.

0:14:260:14:31

I think that depends on the type of work you're doing.

0:14:310:14:34

To make generalisations about what's going on, you do need long periods of time.

0:14:340:14:39

When you've got a bat that lives 30 years,

0:14:390:14:42

then really you should do 60 years to be sure that the first 30 years is the same as the second 30!

0:14:420:14:48

But will Roger ever feel like he's done enough?

0:14:480:14:52

First of all, I thought when you got to 40, you were past doing these sorts of things,

0:14:520:14:57

then I thought, "Well, perhaps when you get to 50, you're past it."

0:14:570:15:00

And at the moment my wife thinks that it's high time that I hung up my boots.

0:15:000:15:06

To be fair to her, it will have to come one day.

0:15:060:15:11

Determination is the watchword for mammal lovers.

0:15:130:15:16

Their dedication spans decades.

0:15:160:15:19

These long-term studies often provide the information others need

0:15:190:15:23

when planning our modern world.

0:15:230:15:25

Thank goodness amateur naturalists have the stamina and commitment

0:15:250:15:29

to keep going.

0:15:290:15:31

I want to be someone who knows as much as possible

0:15:310:15:35

about European brown hares.

0:15:350:15:37

And I'd much rather be here even though it's raining

0:15:380:15:41

than sitting in an office.

0:15:410:15:43

I'm not just standing here getting wet.

0:15:430:15:46

I'm pursuing something I really want to do.

0:15:460:15:49

This pretty suburban garden in Hertfordshire

0:15:520:15:55

just 15 miles from London is surprisingly close

0:15:550:15:58

to where Gill Turner likes to spend most of her time.

0:15:580:16:02

It's 5.30 in the morning

0:16:120:16:14

and Gill is already on her way.

0:16:140:16:16

She is one of only a handful of amateur naturalists in the UK

0:16:160:16:20

studying the secretive brown hare.

0:16:200:16:22

I prefer to come out in the early morning

0:16:220:16:25

because the light's better then

0:16:250:16:27

and there's more chance of seeing them still grazing from the night before.

0:16:270:16:32

I've been aware of the hares in my area for many years.

0:16:320:16:35

I started to wonder what they were up to basically

0:16:350:16:40

and try and understand why their numbers were dwindling.

0:16:400:16:43

It was the Romans who introduced hares to this country

0:16:480:16:51

about 2,000 years ago.

0:16:510:16:53

They were once widespread throughout Britain

0:16:530:16:56

but have now disappeared from many places.

0:16:560:16:59

When you see something

0:17:000:17:02

running at...that looks like a very large rabbit

0:17:020:17:05

running at 45mph across in front of you,

0:17:050:17:10

you can't help but think Britain's fastest mammal,

0:17:100:17:13

you know, that's incredible.

0:17:130:17:15

For 15 years, Gill has immersed herself in the life of hares,

0:17:170:17:22

honing her field skills, so she can get as close as possible.

0:17:220:17:26

We're just coming up to the meadow where I know the hares are

0:17:260:17:29

so if possible could we be quiet and creep over there without making too much noise?

0:17:290:17:36

(Thank you.)

0:17:360:17:38

Keep this way.

0:17:450:17:48

Can you see down there?

0:17:510:17:54

Can you see that brown...?

0:17:550:17:58

There's two hares down there...

0:17:580:18:00

together.

0:18:000:18:02

Did you see that at all? Oh, dear.

0:18:040:18:06

Sometimes it takes the eye of a true amateur to spot what's hiding in the field.

0:18:060:18:12

Can you see them?

0:18:200:18:22

I can see two hares.

0:18:220:18:24

They're both grazing.

0:18:250:18:27

I think they're siblings, part of a group of three.

0:18:280:18:32

I suppose there's a possibility that...

0:18:320:18:35

..as they get older they'll attract...

0:18:360:18:38

..bucks.

0:18:400:18:42

Shall we try and get a bit closer? OK.

0:18:420:18:45

Probably in this length of grass,

0:18:470:18:49

the first the first thing you'll see are the ears.

0:18:490:18:52

When I'm photographing them, and if they come really close to me,

0:18:590:19:03

I have a job to keep my camera steady because it's so exciting.

0:19:030:19:06

Each time I think, "Oh, I've obviously got a brilliant photograph this time."

0:19:060:19:10

SHE LAUGHS

0:19:100:19:12

CAMERA CLICKS

0:19:150:19:16

Gill's photos help her to understand behaviour

0:19:160:19:20

and identify who's who.

0:19:200:19:22

If it's a buck and a doe,

0:19:220:19:24

it's possible that they'll completely ignore me

0:19:240:19:27

because they're fully occupied in what they're doing.

0:19:270:19:30

And with youngsters,

0:19:300:19:32

they're so oblivious,

0:19:320:19:35

especially if they haven't had any contact with humans anyway

0:19:350:19:38

but they're easy to photograph.

0:19:380:19:40

I think they're animals that not many people know much about.

0:19:420:19:46

And there's so much more to a hare than just looking like a big rabbit,

0:19:470:19:51

you know.

0:19:510:19:52

Their life is complex, it really is.

0:19:520:19:54

These beautiful and entrancing animals have declined dramatically over the last 100 years,

0:19:590:20:04

so more information is needed to help them survive the modern world.

0:20:040:20:08

Gill's observations go to her local records office

0:20:080:20:12

and it's vital studies like these continue through generations.

0:20:120:20:16

My mentor was Tony Holly.

0:20:200:20:22

He lived in Somerset and he was well-known in his field.

0:20:230:20:27

I wrote to him

0:20:270:20:29

and he called me

0:20:290:20:31

almost straight away.

0:20:310:20:33

And I was overwhelmed, actually, it was wonderful

0:20:330:20:37

that somebody as important as him should take an interest in somebody

0:20:370:20:43

who hadn't got any scientific background.

0:20:430:20:45

It was great. He really encouraged me.

0:20:450:20:48

When he died, I felt very much alone in my work

0:20:490:20:52

because I'd had somebody to report to.

0:20:520:20:57

Sometimes when I'm on my own and I'm wet and I'm cold...

0:21:000:21:04

..and I haven't seen a hare,

0:21:050:21:08

I think to myself, "Why am I doing this? Does anybody really care?"

0:21:080:21:12

And I've got friends who think I'm mad, but I like to think that I've got enough field experience

0:21:120:21:18

and I've spent enough time watching the hares without interfering with them,

0:21:180:21:22

that I have gained some knowledge

0:21:220:21:25

and possibly seen things that other people don't see.

0:21:250:21:29

Hares, like most mammals, find themselves at the rough end of human development.

0:21:290:21:34

Intensive agriculture, housing, industrialisation

0:21:340:21:38

and roads all take their toll.

0:21:380:21:40

One mammal in particular was pushed right to the brink of extinction.

0:21:420:21:47

Rare, elusive...

0:21:470:21:48

nocturnal...

0:21:480:21:49

No wonder James Williams in Somerset has to make do with decidedly unglamorous evidence.

0:21:490:21:55

We're going to go to the otter loo,

0:21:580:22:01

or what I call the otter loo,

0:22:010:22:03

which is a pile of stones in the stream,

0:22:030:22:06

which I check every day.

0:22:060:22:09

They leave a nice juicy heap of pooh, if I'm lucky, a nice spraint.

0:22:090:22:13

That means that I can tell the frequency with which this stream is used by otters

0:22:130:22:19

which gives some indication of the level of population.

0:22:190:22:23

It's very difficult to see an otter.

0:22:270:22:29

I've never seen one here.

0:22:290:22:32

If I wanted to see an otter at the otter loo, I'd have to sit on the bridge for half the night.

0:22:320:22:37

So this is the otter loo.

0:22:370:22:40

This is the side stream of the River Tone.

0:22:400:22:42

Oh, my goodness!

0:22:420:22:43

They must have known you were coming because that set of footmarks there,

0:22:430:22:48

that's otter padding going upstream.

0:22:480:22:50

I washed that sand yesterday

0:22:500:22:52

and there wasn't any otter padding at bedtime last night,

0:22:520:22:55

so I'm very pleased.

0:22:550:22:56

On my little stream. Excellent.

0:22:560:22:59

At the moment I'm quite excited because I think I've got a bitch and cub

0:23:070:23:11

and so I'm checking to see whether this is one woozle or two weasels,

0:23:110:23:14

or whatever Christopher Robin said.

0:23:140:23:16

But I think an otter would go one, two and be off

0:23:170:23:22

and the fact that we've got more, I'm hoping that that is the cub

0:23:220:23:26

and that's the mother there.

0:23:260:23:28

And this spraint...

0:23:280:23:30

That's a very typical otter spraint,

0:23:300:23:32

a sort of black shapeless, crinkly object...

0:23:320:23:35

..which it gives me great pleasure to see.

0:23:360:23:39

Otters signal to other otters by leaving their pooh on a rock

0:23:390:23:43

as a smelly warning that this bit of river is already occupied.

0:23:430:23:47

Trespassers are not welcome.

0:23:480:23:50

Why otters and not any other species?

0:23:540:23:57

Because all other species are inferior.

0:23:570:24:00

Rabbits are worse at being rabbits

0:24:010:24:04

and, er...

0:24:040:24:06

any fool can be a guinea pig or a fox.

0:24:060:24:09

But it takes an expert to be an otter.

0:24:090:24:11

They really are in control of themselves, in control of their environment,

0:24:110:24:15

they're just a very exceptional grade of animal.

0:24:150:24:19

HUNTING HORN IS BLOWN

0:24:210:24:22

James's admiration came out of a long but unusual relationship

0:24:240:24:28

with otters.

0:24:280:24:30

We were totally involved in otter hunting.

0:24:300:24:33

Father was master of the otter hounds

0:24:330:24:35

and so was I eventually.

0:24:350:24:37

In those days, there was no form of conservation

0:24:370:24:41

other than the hunts, really,

0:24:410:24:44

who paid money to the farmers where otters were found

0:24:440:24:48

who gave Christmas presents to gamekeepers to not trap the otters to destruction,

0:24:480:24:54

so the hunters were the conservationists of the day.

0:24:540:24:58

When the decline came and pesticides started to harm the otters,

0:24:580:25:04

it was the hunts that drew attention to this

0:25:040:25:06

and the hunts that provided most of the data which enabled people to get to grips with it.

0:25:060:25:11

I do think since the 1940s

0:25:120:25:14

I have accumulated

0:25:140:25:16

a body of experience and knowledge

0:25:160:25:18

which ought to be recorded

0:25:180:25:20

and passed on

0:25:200:25:21

because the rivers are not in a totally healthy state now.

0:25:210:25:24

They're cleaner to the eye,

0:25:240:25:26

they don't smell as much and if we want to have some wildlife

0:25:260:25:29

we need a new generation of people to come along.

0:25:290:25:32

James's passion for otters led him to run the Somerset Otter Group,

0:25:320:25:36

an 80-strong band of amateur naturalists

0:25:360:25:39

who routinely check a particular stretch of river.

0:25:390:25:43

By putting all the data together,

0:25:430:25:44

he gets a unique insight into the local otters.

0:25:440:25:47

We gradually build up a picture of evidence,

0:25:490:25:51

a bit like lots of little creatures build up the Great Barrier Reef.

0:25:510:25:55

Little bits, little bits, little bits all add together.

0:25:550:25:58

It may not seem as if you're making a lot of difference

0:25:580:26:01

but I have had one or two things which I think were of importance.

0:26:010:26:05

We picked up a dead otter and sent it away for analysis

0:26:050:26:10

and it turned out to hold a world record

0:26:100:26:13

of dieldrin at a time about six, seven years after dieldrin had been banned

0:26:130:26:18

and it was traced back with the help of some experts

0:26:180:26:22

to a government cloth factory

0:26:220:26:24

where they were using dieldrin.

0:26:240:26:26

We found that. The public do help.

0:26:260:26:29

The fishermen do help.

0:26:290:26:31

Farmers help.

0:26:310:26:32

Birdwatchers are a very great source of information.

0:26:320:26:35

We put it all together and gradually we're getting most of the jigsaw.

0:26:350:26:39

In some ways, it's a thankless passion,

0:26:390:26:42

not least because James never sees an otter on his land.

0:26:420:26:46

Does it take dedication?

0:26:470:26:49

I suppose it does take dedication to study a species that you never see.

0:26:490:26:53

This nomadic creature comes mysteriously through my garden at night.

0:26:540:26:59

It doesn't give twopence about us.

0:27:000:27:02

It's just going through the river as it has done for hundreds of years.

0:27:020:27:06

Our presence is nothing to the otter,

0:27:060:27:08

but the otter's presence is everything to me.

0:27:080:27:11

Otters, like all our animals, need people who care deeply about them.

0:27:110:27:16

Our British wildlife needs a healthy environment

0:27:160:27:19

and it doesn't take much to upset the balance.

0:27:190:27:22

Otters live right on the cusp of what it is possible for them to live.

0:27:230:27:27

If the otters go, it means the streams are in a mess.

0:27:270:27:30

It means the fish are in a mess. It means the dragonflies are in a mess.

0:27:300:27:33

It means that kingfisher that just came past us won't come past.

0:27:330:27:36

If the otters can't hack it, nobody can hack it.

0:27:360:27:40

We've got to have clean rivers.

0:27:400:27:42

The hallmark of the amateur British mammal lover

0:27:420:27:45

is dedication -

0:27:450:27:47

and thank goodness.

0:27:470:27:48

Without them, many of our mammals might quietly disappear

0:27:480:27:52

without most of us noticing.

Next time, on Born To Be Wild,

0:28:060:28:08

passions run high for the small and understated.

0:28:080:28:11

They're about two millimetres across.

0:28:110:28:13

HE LAUGHS

0:28:130:28:15

The rare and elusive...

0:28:150:28:16

There's not enough...

0:28:160:28:18

The less than glamorous but fascinating...

0:28:180:28:20

Eugh!

0:28:200:28:22

And the minibeasts that keep our rivers alive.

0:28:220:28:24

-That's it.

-What's he doing in there?!
