All language subtitles for Lost Land Of The Volcano BBC 2009 720p EN sub 3of3

On the far side of the world
is a remote tropical island,

carved by waterfalls
and covered in thick jungle.

New Guinea.

At its heart are
rugged mountains and deep gorges.

It's one of the least
explored corners of our planet.

Over nine months,
a team of scientists,

adventurers and filmmakers have been
on an expedition into the unknown.

Helped by a local tribe,
they've found some of the strangest
creatures on Earth.

Look at that.

Oh, wow, wow wow, wow! Jeepers!

Now, they're leaving base camp
and striking out in two directions.

One team is venturing
to an erupting volcano.

Oh! It's being thrown
a kilometre into the air.

The other team will journey deep
into an unexplored crater,

hoping to discover
spectacular animals never seen
by the outside world.

What is that?

Absolutely out of this world.

Good God, look at that.

And they make a dramatic discovery.

That is the biggest
I have ever seen.

Oh, my word, have a look at this.

New Guinea,

the largest and most mountainous
tropical island on Earth,

so impenetrable,
large areas remain uncharted.

At the heart of this vast island
is Mount Bosavi, an extinct volcano.

Oh! Climber and
naturalist Steve Backshall

is leading the first-ever expedition
deep into its huge crater.

This is what we do
expeditions for, places like this.

Unimaginably beautiful,
and totally unexplored.

Very few places in the
world left like Mount Bosavi.

Outside the crater, they've
already found new types of frogs,

lizards and insects.

But inside, there could be
unknown large mammals,

hidden from the rest of the world.

These are the walls
of the crater rim.

It's an almost
perfect volcanic cone.

And what we're looking at now
is the inside wall.

It's no wonder everyone's so
excited about getting in this place.

It's absolutely epic.

Discovering new mammals in the
crater would put Bosavi on the map

and hopefully lead
to its protection.

Loggers are just south of the
mountain and moving closer.

High on the crater rim,
there's a small gap in the trees.

The local Kasua tribe
have agreed to meet Steve here.

They've given their blessing
for the team to enter this,

their most sacred land.

INDISTINCT SHOUTING

The head of the clan that owns
Bosavi is bringing up some magic,

he's singing us into the crater,

he's opening it for us so
that the nature will be

allowing us in there and not angry
with us for going into the crater.

And we have to walk
under the magic stick.

Even the Kasua rarely come here.

Fiercely territorial,
this is the first time

they've guided an expedition
into their magical crater.

It's very steep and very wet.

Have to go very slowly.

Well done.

The clouds are just
coming up to meet us.

Down there...

is a genuine lost world.

Just don't want to take
a wrong step here, anywhere.

They need to find somewhere
to build a rough camp.

Only then can they call in
the rest of the team.

Outside the crater,
at the foot of Mount Bosavi,

the old base camp is packed up.

For now, intrepid
bug expert George McGavin

is venturing off on a side trip.

We're going.

Very excited about this indeed.

George will be searching
for wildlife on the slopes of
a very different volcano.

One that's erupting.

It's 700 miles to the east,
on the island of New Britain.

Recently it's been quiet,
but it could go off at any time.

Mile after mile is choked with ash,

but George is keen to see what,
if anything, can survive here.

At first, it appears barren.

It's more hell on Earth
than wildlife hotspot.

Basically, it's just...

just covered in ash, and there
isn't anything growing at all.

It's all dead, and decaying.

It smells of sulphur.

George's first discovery

is perilously close to the crater.

This is a beautiful bird.
It's a brahminy kite.

The fact that it's flying around here

means that there has to be
enough food for it to eat.

Although I can't see much for it
to eat, but it clearly is hunting.

If it's not careful it'll be
hit by a rock in a minute.

It seems to be flying very
close to the crater there.

A bird of prey is a promising sign,

but George must also keep an
eye out for flying rocks.

Mount Bosavi was once
an active volcano.

It stopped erupting 200,000 years
ago, and rainforest took over.

Since then it's remained unchanged,
untouched and unexplored.

Steve and the team are following a
river to the heart of the crater.

It's slow going,

but it's the best way to
cover ground in a dense jungle.

Not a bad spot.

Good spot.

Shall we try and get a tarp
up before this rain starts?

Yeah, yeah.

Shelter is essential.

New Guinea is one of the
wettest places on Earth.

It can pour for days on end.

The Kasua tribe come from the
outer slopes of the mountain.

These old men remember a time before
any contact with the outside world,

when their clan were cannibals.

HE SPEAKS NATIVE TONGUE

They said their fathers were
great warriors and used to battle
with nearby clans quite often,

but they also have,
it seems, very vivid memories

of them actually killing and
eating their enemies.

The chief here is describing how
he remembers them cutting the thighs

into halves and putting them on
stone fires to cook them,

and it seems that it was not
so much a ceremonial thing

but actually just
for the meat, for the protein,
for the fact that meat was

quite scarce around here and to have
human meat was as good as anything.

They no longer eat people, but
they are still expert hunters,

totally at home in this jungle.

Without the tribe,
the expedition would be lost.

200,000 years ago, Mount Bosavi
would have looked like this,

hostile and desolate.

But George knows better than
anyone where to find signs of life.

This is definitely where
I'd expect to find something.

Oh! Aha!

Look at that, baby! Look at that.

A rhinoceros beetle larva.

It's a whopper. Look at that.

Head's up here, big jaws,

and they just eat this decaying
wood and fibre.

Going to have to put him
down somewhere.

Put him on there while I attack
the rest of this.

Ah!

Ha ha!

There's the adult.

So there...

is what this will become eventually.

Rhinoceros beetle.

Absolutely brilliant.

Some creatures endure the volcano,
others actually seek it out.

I can see two birds that look
like sort of large hens.

They're megapode birds,
and, bizarrely,

they depend on this active volcano.

In the Bosavi crater,
Steve and the trackers fan out to
explore for the first time.

Steve will climb, crawl and swim the
rivers to find out what lives here.

Chief Sigaro and the trackers
search the high ground.

In the valley, Steve stumbles
across something remarkable.

Absolutely out of this world.

It's a rare kind of
kangaroo that climbs trees.

And it's probably
never seen people before.

The fact that this animal is totally
unafraid of humans, just wandered

straight past us, means the wildlife
here has never been hunted before -

it hasn't seen people before.

I never expected to have a tree
kangaroo on our first morning

that we've been up and running.

This is a phenomenal start,
a phenomenal start.

It's time to call in wildlife
cameraman Gordon Buchanan.

Gordon's mission is to film
any animal the team finds.

Many of the rainforests that I've
been to before are quite flat.

This is a very, very difficult
terrain, and without a doubt

there'll be species down there that
are completely unknown to science.

Finding and filming a large
mammal that no-one knew existed

would be the greatest prize of all.

But in this rugged terrain,
it's a daunting prospect.

Gordon has with him two scientists,

who will help to identify any
mammals the team discovers.

Muse Opiang and Kris Helgen
set up their makeshift jungle lab.

But Gordon has no time to unpack.

One of the trackers has
found another tree kangaroo.

We've just had a shout from one of
the local guys, shouting "toonape"

which is the tree kangaroo, so I'm
hoping to catch up before it goes.
As quick as we can. Ah!

Oh, yeah, he's here.

Oh, goodness me.

It's a glorious tree kangaroo,

just literally six, seven
metres in front of me.

For me, these animals
are the height of weird.

They're one of the strangest
animals that live in this forest,

I think because they're
recognisable, they're kangaroos,

but these kangaroos live
in the trees.

It's like a cross between
a koala bear and a kangaroo.

Oh, he's very cute.

Really short, stocky build.

Huge claws. The nails must be
about two to three inches long.

Oh, yes, he's eating, oh, lovely.

Now that's a really good sign,

because animals that feed
are relaxed.

100%, this animal will never
have seen a human being before,

so that's why we're able to stay
as close as this, as we are.

Tree kangaroos are incredibly rare.

Outside the crater, they're heavily
hunted and afraid of people.

Inside,
they aren't bothered by humans.

George's volcano could
go off at any time,

but he's too engrossed to care.

He's hot on the trail of
the peculiar megapode bird.

One of them's just landed
really clumsily on that branch

and thrown up a whole shower of ash.

It's very hard to get close to
these birds, they're very skittish.

(I reckon if we inch
forward to this ridge...)

(They've landed, they're down.
There's two just on the ground

(over there.)

Unlike any other bird, megapodes
bury their eggs deep in the ash,

and let the warmth
of the volcano incubate them.

(The megapode egg-laying site
is just down there.)

If George is to find an egg,

he must wait for them to finish
and hope the volcano stays quiet.

Mount Bosavi is extinct now,
but the eruption left behind

this crater four miles wide,
enclosed by towering walls.

Steve's still out
exploring the river...

..but it's not just the
rocks that are treacherous.

This plant is making
life here absolute hell.

They're everywhere and
they're called a stinging tree.

On the underside of each leaf
are thousands of little hairs

all filled with poison,

and the sting, actually, can carry
on going for two or three months.

Ow!

Serves me right!

Every little stream is investigated.

Any one might hide a surprise.

Sticking up out of this vine
are lots of little twigs,

except they're not twigs,

they're leeches, just waiting
for something to walk past.

They're switched on by
warmth and also by

the carbon dioxide you breathe out,
and if I just breathe on them...

Look at that.
Instantly feeling around

for the source of it.

Looking for a blood meal.

I hate them!

Steve may hate them,

but leeches mean there must be lots
of warm-blooded animals to feed on.

It's an encouraging sign
for the mammal experts.

Kris Helgen, from the Smithsonian
Museum, is the world authority on

identifying new mammal species.

From the river, Steve's
brought in a fragment of skull.

You can see the pre-molar's fallen
out and that corresponds to this too.

When you're studying mammals,

the dentition, the arrangement
of the teeth, the amount
of teeth that are there,

that's one of the most
important things in figuring out
what something is.

We're really lucky as
mammologists, because if we
find a single tooth or a

single piece of skull, we can often
tell exactly which species it is.

This is a mystery still,
but I'd like to find the animal

that goes along with this skull.

Let's see what we can find
in the forest.

Wow. So I could be holding
in my hand the skull of

a new species of mammal.

Let's see where it takes us.

Gordon and the scientists head out
to look for Bosavi's mystery mammal.

Kris thinks it could be a new type
of cuscus, a small bear-like animal.

There's spines on
all these branches.

To be certain,
they'll need to catch one alive.

It's quite a good flat area here.

As it's such a big trap,
I need to find a big, flat space -

you don't want any parts
of the wire suspended.

Chuck this up the end.

Finding any animal, small
or large, would be a bonus.

Everyone has their own
technique for baiting the traps.

Tell you what, a little bit of
peanut butter never hurts as well.

Throw that in the back there.

Smell it for miles.

At the volcano,
George's wait is nearly over.

Now there should be eggs
buried somewhere in the ash.

(I think the birds have finished
laying now, so with any luck,

(I should find some
freshly-scraped ground,

(which might indicate
where the eggs are laid.)

Once the megapodes leave,

the volcano will keep the
eggs warm until they hatch.

This looks like exactly
where they've been.

They could be as much
as two metres underground.

I reckon down there is an egg.

When the chicks hatch out,
alone and in the pitch black,

they claw their way to the surface.

Well, I'm almost at...
as far as I can reach down.

Yes! I think I've got one! Ha ha!

There is a megapode egg.
The size of it!

The chicks emerge well developed,
fending for themselves from day one.

They never know their parents.

What a tough start to life
in this tough environment.

That was almost
a scrambled egg then!

He returns the egg to safety,

but nearby, animal tracks lead
him further into the danger zone.

That's getting a little
too close for comfort.

That's coming halfway
down the slope now, easily.

In the crater, Gordon and
Kris are still out searching.

No, no. It doesn't really go in.

That broken bit's hollow.

They're looking for
the mystery cuscus,

the mammal whose
skull Steve found earlier.

Have a look in there.

Oh, crikey!

You got somebody? Yeah.
Somebody's home?

Something is holed up
in an old tree trunk,

but it's too deep to see
what it is.

Just sitting there.
Let me have a look in there!

Have a look.

God, that's the weirdest thing.

Oh, wow.

Gordon will have
to wait for it to emerge.

What I want to do is just
set up, maybe over there,

wait for it to get dark
and see what happens.

Quite exciting.

If it is the new type of cuscus,

Gordon doesn't want to miss
his chance to film it.

It's looking pretty good.

Just see what happens
once I climb down.

A small camera pointing
into the tree stump

will warn him if
the animal starts to climb up.

He can then film from a
distance without disturbing it.

The problem with this
situation is just the waiting
for the animal to come out.

It will definitely come out,
it's just a case of when.

The long wait begins.

The volcano is stirring,

but George can't resist exploring
just a little further.

This is what's making those tracks.

It's really quite
a large crab, and...

Woo hoo! Ow.

The eyes are on these little
stalks, which flick up and down,

so that's how it keeps
its eyes out of harm's way.

But that is clearly very
at home here on this ash pile.

I mean, it's a long way from the sea.

Crabs are scavengers.

They've come to pick over
anything killed by the volcano.

George must beat a hasty retreat.

His wildlife survey could be over.

The volcano is kicking off.

It's throwing out massive
amounts of red hot rock,

and you can hear the bangs as they
hit the ground, the great thumps.

Look at that.

Oh, this is incredible.

I mean, it's fantastic to be this
close to an active volcano.

It's throwing out massive
amounts of hot rock, red-hot rock.

It's throwing them
a kilometre in the air.

That is one of the most spectacular
sights I think I've ever seen.

This is an infra-red camera, so
it's able to see all the hot stuff,

which the big cameras can't see.

When this thing erupts, you can
feel the shockwaves hitting you.

That thing is on top of a
chamber of molten rock three

kilometres wide and
three kilometres deep.

I mean, it's just...terrifying.

But to be absolutely honest with you,

I'm actually feeling quite
apprehensive, because

this is a force that...

just is too immense to
even think about.

You couldn't speed away from this
in a hurry. You'd be toast.

Good grief!

Four hours on, and still no
sign of the unknown mammal.

I don't often feel as if I've got
the upper hand on an animal.

I think in this case I do,

because I can see the monitor of the
camera that's looking straight down.

So it gives me a bit of warning.

If he's a bit agitated from me
looking down into that tree stump

earlier on, he might just shoot out
and I won't get any shots of him,

but at least that camera up there,

I can see the moment
he starts to climb up.

This is really exciting, because
other than just two little eyes,

I just don't know what's in there.

It's a mammal of some sort,
but who knows what it is?

OK, he's starting to come,
he's starting to come.

Great! Come on, out you come.

Come on, come on.

We're evacuating camp,
and in a hurry.

And with very good reason.

Show me, show me, show me.

That one?

That's one of the bombs
that came out.

We thought we were safe here, we were
a long way away, and it landed here.

That would have
killed you instantly.

So I think we should all go now.

George's mission has
come to an abrupt end.

In the calm of the jungle night,
Gordon's patience could be rewarded.

He's going to come out, he will.

Come on, come on.

Here he comes,

looks like a mole.

I know it's not a mole, but it's
very hard to tell what he is.

Oh, God, my heart is beating
out of my chest, come on!

Please, please, please... oh, there
he is, there he is, there he is!

You little beauty!

What is that?

Gosh.

I haven't got a clue what he is.

That's weird.

That is so weird.

OK, if he just comes out a bit more,
I can get an idea of his body shape,

but...

you can see his teeth...

his eyes are shining like that
because of this infrared light

bouncing straight back at me.

What a pretty animal.

OK, out you come, come on,
come on, please, just come out.

Gosh, look at that.

Oh, gosh, no, I think
he's trying to go off -

he's going to try and grab a limb

and go off, oh, there.

There could well be new species
living here in the crater,

and my job is to get shots of them,
and let Kris try and identify them.

Whatever it is, it appears
to have no fear of people.

If unique to the crater,

it would help prove just how
special the jungles of Bosavi are.

Whilst Gordon is deep in the jungle,

Steve is on the river.

No-one knows what may
lurk here at night.

Eughh! Look!

Whoa! They've been roosting just in
the branches above us so as we've

come across with our torches and
lights, it's given them a shock.

Steve is being mobbed
by torrent flycatchers,

birds found only in New Guinea.

Eughh!
It just flew right into my face.

It may be wet, but no-one imagined
there would be ducks in the jungle.

Now that is something
I really didn't expect to see!

Salvadori's teal - unique to
the mountain rivers of New Guinea.

They almost look like they're
just enjoying the rapids!

That is a glorious
looking little tree frog.

Off he goes.

Wow! These are actually
torrent breeding frogs,

so they love breeding in
fast-flowing water like this.

Let's see if we can get a glance

at what makes this
frog really special.

That eyelid is laced
through with a network

of veins...

and it's absolutely beautiful.

He's got a face that
you just can't help but love,

and you know that any second,
although he's sitting

comfortably on my finger here,
he could, without a single warning,

just spring away and be gone.

Come on, go and find
yourself a...girlfriend.

Not the ear!

Mount Bosavi is so large
it generates its own weather.

For much of the night
it's been raining,

and the sleeping area is flooding.

There's no respite from the mud.

And it's tinned spaghetti
for breakfast, again.

Kris and Steve are reviewing
Gordon's footage from last night,

in the hope it's the mystery
cuscus they've been looking for.

Those big beautiful eyes.

Yeah.

It's small little ears,
they're in the fur.

And light belly here. Light belly.

I reckon that is our cuscus.

You think? I reckon it is.

I reckon it is, it's dark.

So this could be the animal
that that skull belongs to.

This could be the mysterious Bosavi
cuscus. This could definitely be.

Wow. So what we really
need now is to actually catch
one of these in our traps.

Then we'll get a feel for the colour,
we'll see what it really looks like,

and if that really is a good
match for the animal's teeth

that we've been looking at
that are so distinctive. Yeah.

This could be really exciting now,
I think this is our animal.

It looks like a major new discovery,

but pictures alone
are not scientific proof.

To get that, they'll need to catch
one in the few days that are left.

Bosavi's forests extend
right up to the summit.

A vertical kilometre above Steve and
Gordon, the jungle is much wetter.

George is joining the
team on the mountain.

His mission... to explore the
cloud forest clinging to the summit.

Being one of the world's
leading experts on insects,

if there's anything
unusual, he'll find it.

This volcano is just like...
like an island in the sky.

I mean, it's 9,000 feet above
sea level. Look at that wall!

God, that is unbelievable.

But as you can see,
the weather's really very cloudy.

It's amazing how it changes...

incredibly heavy rain, very dark,
and then just a little...

a little gap in the cloud
cover there.

So it's touch and go whether
we'll be able to land there.

We're gonna make it.

We're clear to land,
we're clear to land.

Oh... yeah, we're here!

Fantastic.

This precarious cliff edge

will be George's camp
for the next couple of days.

A thousand metres below him, they're
on the look out for new animals.

Top of their list -
the unknown cuscus.

They search every hole...

Every nook and every cranny...

Mate, this place is leech central.

..By day...

..And by night.

Camera traps are set.

Leech. Any mammals that come in
here they'll try and get on to them,

including humans.

A face only a mother could love.

The team use every
piece of kit available.

Lots of insect noise, some frogs.

Some weird stuff,
I don't know what it is.

It's incredible that a frog this
tiny size, I mean it's no bigger

than the end of my thumb,
can make a noise that loud,

just puffing itself up like a
great big balloon and then

squeezing all the air out.

But this jungle is
so dense and so steep,

it's hard to find anything.

On the summit, George is out
exploring the peculiar mountain
moss forest for the first time.

He's stepped into another world.

It's like Lord Of The Rings habitat.

You'd expect orcs and
elves appearing any minute.

The whole forest is just humid,
100% humidity all the time,

and this may look like
solid ground, but it's not.

Look, I can go
through there and beyond.

I can put my hand... I can go,
probably, I can put my whole arm

right through up to the hilt and
that's just roots and soil and space,

and that's what we're standing on.

The whole thing is just a sort of...

a mirage, almost, of plants and soil,

but the soil's really interesting
because the soil isn't just here,

it actually occurs up on
the plants as well.

So it's actually aerial soil -

all of this is just growing
on a single thin branch.

It's a huge carpet...

of moss and soil.

It's almost like...

a different world.

I haven't seen that one before.

Absolutely amazing.

I mean, decay just brings fungi,
bacteria, mosses -

just everything
is feeding off what's here.

And look at that,
that is the most exquisite

tiny fungus growing on a dwarf
bamboo, and it is just incredible.

Ooh, look, look!

Good God, look at that!

I just saw that there in the ground.

It's huge!

This is a flatworm.

Well, that's exactly the sort of
animal you'd expect to find

in this constantly
wet environment.

Flatworms come in all shapes and
sizes... that's the underside...

but I have never seen
a flatworm this big before.

It's absolutely amazing.

Tiny little head end,
that's the head end there.

This habitat is incredibly special,
because there are animals and plants

here, orchids and insects and higher
animals you won't find anywhere else

in the world. But also because
it occupies a very, very small
area and with increased

global warming, that area will get
smaller and smaller and smaller

and eventually it'll all be gone.

In the crater, one of
the trackers has returned to camp

with a wild animal,
and it's totally trusting.

Oh, wow!

Oh, my goodness, he's absolutely
beautiful. Come on little fella.

I think it's our guy.

I'm going to look in his mouth
in a bit and we'll know from his
teeth but this looks right on.

This is a dark-furred
cuscus, it's a montane cuscus.

It's very much like
the skull I suspected.

The skull was similar to a different
species called the silky cuscus,

and the body is too,
you can feel that silky fur.
It's really, really thick.

I guess this has adapted to
living in a mountain environment.

That's right. He seems to like you.

He's got a very, very strong,
but not actually unpleasant, smell.

But it does hit you.

This is the mammal that Gordon
filmed emerging from the tree stump.

I'm calling this the Bosavi cuscus,

because I really think it has a
lot of distinctive features.

We're gonna find out more
as we look closer, but...

I just... I can't even begin
to describe how it feels

to have an animal in my hands
that is this beautiful

and, in all probability, has never
been seen before by science.

I think what we have is a
cuscus that long ago has been

isolated on this volcano

and has just not been
able to have any contact with
any of its relatives and

has become something here in
isolation that is unique to Bosavi.

He's totally chilled out. He's got
no idea quite how important he is.

So gorgeous. Yeah!

Little guy!

You're a major scientific discovery.

How about that?

I travel the world looking for new
species in many different places

and we find new mammals, it still
does happen, but so many of them,

most of them are things like bats
and rodents, and to find something,

a marsupial, an animal that's
this size is really exciting,

it's a cause
for a major celebration.

Crack open the champagne,

or crack open the bully beef!

It's a brand new sub-species of
cuscus, and Bosavi is its only home.

If these jungles are logged, we'll
lose animals like this forever.

Both on the summit and
in the crater, the rainforest
is undisturbed by humans.

Animals are remarkably naive.

Almost incredibly, I'm about six
feet away from an ornate fruit-dove.

You couldn't normally get this close
to birds, especially on the nest.

She's camouflaged to perfection

against the foliage -
green with a little bit of

blue at the back, this ochre-y
head and a white bit underneath.

She's being very vigilant,
she's watching me very carefully

and turning her head from side
to side, very slowly. Amazing.

Thing about animals here is that they
really aren't experienced, they don't

know what humans are all about yet,
which may be a problem for them.

The history of humans has been that
if animals are edible or hazardous,

they usually end up dead.

In the depths of the crater,
it's raining again.

It's been a long, hard expedition.

Exhaustion and
illness are setting in.

There's been an outbreak of
intestinal worms in the camp,

so we're all taking
these worming tablets

which will pretty much kill
everything we've got in our guts.

Makes you feel really run down,

but this tablet
just kills everything.

Leeches are infesting camp.

Gordon and Kris take time to
see if anything strange

has been caught
on the camera traps.

Let's have a look.

OK, that's me... still me.

Kris is one of the few people in
the world who can distinguish

what's just rare
from what's totally new.

Oh!

Is that a tree kangaroo? It's not a
tree kangaroo, but it is a kangaroo.

So it's a wallaby. Moves along the
forest floor here in the crater.

See what else we've got.

I've got a good
feeling about this one.

They scan hundreds of images,

and eventually, they strike gold.

Wow! Have a look at that.

What is that? That long, naked
tail, what do you think that is?

It just looks like an enormous rat.

Yes, it's a giant rat,
it's a woolly giant rat.

Jeez, it must be
that size without its...

so that size with its tail?

Exactly, almost a metre long.
Seriously?

And this camera trap proves
that an animal like that is here.

To get conclusive evidence

whether this is a new species,
you need more than a photograph.

This black and white photograph
isn't going to do it.

We're going to have to see if we
can find this animal in the flesh,

hold it, see what this animal is.

But just using your experience,
this could be a new species?

There's no question in my mind
this is a giant woolly rat,

and I suspect Bosavi
has its own kind.

Wow, that would be
some amazing find.

No-one imagined just how rich
this mountain would turn out to be.

In the weird moss forest that
clings to the rim of the crater,

George is setting a trap.

It's carefully positioned,
right on the cliff edge.

Once night falls, a high-powered
light bulb will be switched on

to attract insects to the sheet.

And that's going to be...hopefully,
it's going to be heaving with bugs.

Down below, the hunt is on
for the giant woolly rat.

Gordon and Steve head off
in opposite directions.

They will search all
night if they have to.

Somewhere out there in the darkness
is one of the world's biggest rats.

At night, the jungle has
its own special magic.

This tree is covered in bracket
fungus, and you can see all the

tiny little spores being
discharged,

it makes it look as if
they're actually steaming.

In the early hours,
Kris finds another animal
with no fear of humans.

It looks like a giant hamster,

but it's a painted ringtail.

Oh, he's absolutely gorgeous!

Not a new species, but definitely
one of the most beautiful animals

that lives in this forest.

Gosh, he really is.

The fur is just exquisite.

It is just so dense and so soft.

You can see at night time
this place just comes alive.

We've done so much walking about
this forest finding nothing, and

you only have to find something like
this and it makes it all worthwhile.

You forget all that misery
and all that hardship.

On the cliff edge, George
can hardly believe his eyes.

I'm just overwhelmed.
I never imagined I'd see

such a diversity of moth.

I mean, some of these things
I've never seen before in my life.

The variety of moths here
is absolutely staggering!

There's geometrids, hawkmoths,
there's fruit piercing moths,

and it's raining,
it's tipping it down!

This shouldn't be happening,

and these bulbs only work
in a radius of about 200 yards.

All this has come from a
200 yard radius to this bulb.

Can you imagine how rich
this forest actually is?

Almost beyond my understanding.

Look at that.

I'm absolutely...incredulous.

My God, look at it!

Look at that one, that
brassy gold colour.

In the crater, Steve's
searching for the giant rat,

but he's discovered a tarantula.

Look at that!

The way he's tilted back there,
you can see he's rocked back

in order to bring those fangs
into position so he can

bring down the entire bodyweight,

plunging those fangs into whatever
it is that's annoying him.

Come on then.

Now don't go, don't go.

I do have to be careful here,
I'd be a lot more ambitious

if I knew what it was

and if we were in a...

less remote environment.

But to get bitten
or stung by something

like this out here...

..could be really sketchy.

I have never been anywhere
where I've seen the diversity of
moths that I'm seeing here.

If you'd told me, I wouldn't
have believed you, but it's here.

This one!

That's a different hawkmoth. That's a
different one come in now, just now.

V-shaped wings, very fast flyers,
really strong moths.

Fantastic colouration there.

Oh, look now, there's a hawkmoth too.
Now, I've never seen that one before.

What percentage of these will be new?

It could easily be...

a quarter, it could easily
be a quarter of them.

This is a very interesting moth.

It's called an arctiid moth
and when it's annoyed,

it produces very horrible-smelling
fluid from the thorax.

There, see that? Look at that!

That is amazing!

What a defence.

And that tastes really foul.

Yuk, yuk.

Even if I'd had to walk up here
on my hands and knees, it would
have been worth it for this.

This one hour of moth mayhem.

A haul of unique
creatures like this proves
Bosavi's forests are priceless.

Honestly!

Gordon gets a shout from a tracker.

Oh, my word, have a look at this!

Oh, gosh, that is the biggest rat
I have ever seen.

That is a murid rat, a true rat,

the same family as the rats
you find in cities and sewers.

You've got a big smile on your face.

The reason I'm smiling is because
this is absolutely a new species.

This is something that doesn't
have a scientific name.

This is one of the largest rats
in the world, and here we are,

holding it.

I just think it's an amazing
creature, found nowhere else

on the entire planet.

That is such a huge deal.

And this animal is so chilled out,
look at him, he's just grooming.

You can tell it's a rat but yet
it looks just so different from

any rat you've ever seen, right?

Yeah. I had a cat, and the cat was
about the same size as this rat.

Any cat that you buy to catch
rats is going to run a mile

from something like this.

Mount Bosavi's such a big mountain,
it's largely unexplored, it's so

isolated that truly, some
of the things we are finding

are new species and
are spectacular new species.

Big rats, cuscus, fantastic animals.

It gave me the heebie-jeebies,
the thought of a giant rat and

I've been going down the holes in
hollow trees looking for big things,

and it's actually kept me awake at
night and here he is, he's just...

oh, he's like a little puppy.

New species of giant woolly rat!

Yeah. No!

That's unbelievable.
Or are you just making it up?

No, no, we got it, we got it, yeah.

God, it was great, so great.

The biggest rat in the world.

Was it in a trap or was it...?

No, just running about the forest,
tame as anything.

That's incredible.

It's time to pack up and
collect George from the summit.

As I stand here, just about to be
whisked away by this helicopter,

I realise that my grandchildren

may not ever be able to see this sort
of habitat or the animals and plants

that live here. It could all be gone.

Now all their findings
will be brought together

and presented to the outside world.

With the help of a remarkable tribe,

they've found hundreds
of spectacular creatures.

He is just a parrot in miniature.

That is absolutely gorgeous!

They've discovered over 40 new
species, from exquisite geckos

to magical moths

and bizarre frogs.

And they've made major
scientific discoveries...

creatures with no fear of people.

Oh, he's like a little puppy!

Mammals that no-one knew existed.

Wow! It's so incredibly rare
that new species of mammal

are found around
the world these days.

This has got to be one of the
most incredible moments of my life.

All of this on one amazing mountain.

The hope is that Mount Bosavi,
once a forgotten corner, will now

become known around the world

and protected as a unique
rainforest of global importance.
