Lonesome George is the most famous tortoise in the world. | 0:00:04 | 0:00:08 | |
He is also the only one of his kind. | 0:00:08 | 0:00:11 | |
His ancestors were slaughtered over a century ago. | 0:00:11 | 0:00:16 | |
Discovered and rescued in the '70s, | 0:00:19 | 0:00:21 | |
he's come to symbolise the plight of the unique animals of the Galapagos | 0:00:21 | 0:00:26 | |
and the battle to restore the islands to their former glory. | 0:00:26 | 0:00:30 | |
For a while, Galapagos was considered beyond saving. | 0:00:33 | 0:00:37 | |
Decades of conservation work | 0:00:37 | 0:00:39 | |
succeeded in buying time, but the wildlife is once again under attack. | 0:00:39 | 0:00:44 | |
Tensions between local people and wildlife run high. | 0:01:01 | 0:01:04 | |
The islands have been brought to the point of crisis. | 0:01:04 | 0:01:07 | |
But those same people may offer the islands their best chance of salvation. | 0:01:07 | 0:01:11 | |
Extreme measures are being taken. | 0:01:13 | 0:01:16 | |
In 21st-century Galapagos, | 0:01:19 | 0:01:21 | |
can its unique wildlife be spared the same fate as Lonesome George - | 0:01:21 | 0:01:27 | |
staring extinction in the face? | 0:01:27 | 0:01:30 | |
The famous Galapagos islands. | 0:01:39 | 0:01:41 | |
A tropical paradise - remote, | 0:01:41 | 0:01:44 | |
fantastical and renowned for their abundance of wildlife. | 0:01:44 | 0:01:49 | |
The islands take their name from the Spanish word for giant tortoise - | 0:01:53 | 0:01:57 | |
this is one of only two places on Earth these reptiles are found. | 0:01:57 | 0:02:02 | |
They're a naturalist's dream - | 0:02:05 | 0:02:07 | |
the most pristine tropical archipelago in the world. | 0:02:07 | 0:02:11 | |
Flung far off the west coast of South America, the Galapagos Islands | 0:02:15 | 0:02:20 | |
are isolated by hundreds of miles of ocean in every direction. | 0:02:20 | 0:02:25 | |
This isolation has led to the evolution of so many unique species, | 0:02:25 | 0:02:31 | |
and that same isolation | 0:02:31 | 0:02:32 | |
has protected them from human colonisation and disturbance. | 0:02:32 | 0:02:36 | |
But the islands are changing. | 0:02:39 | 0:02:41 | |
30,000 people now call these islands home. | 0:02:42 | 0:02:46 | |
They're mostly immigrants from mainland Ecuador. | 0:02:48 | 0:02:51 | |
Galapagos is a province of Ecuador, | 0:03:00 | 0:03:03 | |
and the people retain a strong national identity. | 0:03:03 | 0:03:06 | |
The vast majority have arrived in the past 20 years. | 0:03:11 | 0:03:15 | |
The islands are famous for the tameness of their animals. | 0:03:20 | 0:03:23 | |
Here, more than anywhere else on Earth, humans and wildlife | 0:03:23 | 0:03:27 | |
appear to live happily side by side. | 0:03:27 | 0:03:31 | |
In this pristine wilderness of Galapagos | 0:03:32 | 0:03:35 | |
you can almost believe that you are in a modern-day Garden of Eden. | 0:03:35 | 0:03:40 | |
But in reality, this trusting wildlife is particularly vulnerable. | 0:03:46 | 0:03:51 | |
Despite the illusion of paradise, the animals have been suffering | 0:03:51 | 0:03:55 | |
for as long as people have been present here. | 0:03:55 | 0:03:57 | |
There's no better case in point than the story of Lonesome George. | 0:03:57 | 0:04:03 | |
On the outskirts of town, Lonesome George has his own corral | 0:04:03 | 0:04:08 | |
within the protective boundaries of the National Park | 0:04:08 | 0:04:11 | |
and Charles Darwin Research Centre. | 0:04:11 | 0:04:14 | |
Fausto Llerena is the chief warden | 0:04:14 | 0:04:16 | |
responsible for Lonesome's comfort and well-being. | 0:04:16 | 0:04:19 | |
He's grown fond of his precious charge. | 0:04:21 | 0:04:24 | |
He is unique. | 0:05:12 | 0:05:14 | |
He's in the Guinness Book of Records as the loneliest creature on Earth. | 0:05:14 | 0:05:18 | |
He is, quite simply, the only surviving member of his race. | 0:05:18 | 0:05:23 | |
The only Pinta Island giant tortoise in existence. | 0:05:23 | 0:05:27 | |
The rest of his kind were mostly wiped out by whalers and buccaneers | 0:05:32 | 0:05:36 | |
in the 18th and 19th centuries. | 0:05:36 | 0:05:39 | |
Ships full of hungry men, at sea for months on end. | 0:05:42 | 0:05:47 | |
They had this problem of victualling, | 0:05:49 | 0:05:51 | |
and they got to the Galapagos and they would look forward to it | 0:05:51 | 0:05:55 | |
for weeks because that's where they could get tortoises. | 0:05:55 | 0:05:58 | |
If you've come round Cape Horn | 0:06:01 | 0:06:03 | |
and you've been living off mummified penguins and rotten pork for months, | 0:06:03 | 0:06:08 | |
and you've got the chance of stocking up your ship with several tonnes | 0:06:08 | 0:06:12 | |
of absolutely fresh living meat, | 0:06:12 | 0:06:14 | |
by dumping a few hundred tortoises in the holds, | 0:06:14 | 0:06:18 | |
the quality of life for you increases | 0:06:18 | 0:06:20 | |
a great deal, although it reduces a lot for the poor animals in the hold. | 0:06:20 | 0:06:25 | |
It's thought that Galapagos had 13 races of giant tortoises, | 0:06:30 | 0:06:35 | |
spread across the larger islands of the archipelago. | 0:06:35 | 0:06:38 | |
It was the outlying island populations | 0:06:38 | 0:06:41 | |
that were first plundered by the visiting sailors. | 0:06:41 | 0:06:44 | |
The first race to go extinct, as far as we can tell, was on Floreana, | 0:06:44 | 0:06:47 | |
where the noteworthy Mr Charles Darwin visited in the 1830s - | 0:06:47 | 0:06:53 | |
he was there in the closing stages of the existence of that tortoise. | 0:06:53 | 0:06:58 | |
By 1840, as far as we can tell, it was gone. | 0:06:58 | 0:07:02 | |
In fact, Darwin may have eaten some of the very last ones, and the shells | 0:07:02 | 0:07:06 | |
were thrown overboard from the Beagle as they sailed off, | 0:07:06 | 0:07:10 | |
so it was a different ethic in those days. You had to survive. | 0:07:10 | 0:07:13 | |
Nearly all the populations were decimated by the visiting sailors. | 0:07:16 | 0:07:20 | |
At least two races were considered extinct by the mid 20th century. | 0:07:20 | 0:07:26 | |
While the tortoises of Pinta Island | 0:07:26 | 0:07:28 | |
were known only from skeletons and a 19th-century lithograph. | 0:07:28 | 0:07:32 | |
The Pinta tortoise always fascinated me personally, | 0:07:32 | 0:07:34 | |
because he was such a weird-looking animal. And, as you can see, | 0:07:34 | 0:07:38 | |
it just doesn't look like other tortoises. | 0:07:38 | 0:07:41 | |
It's just taller and the texture of the shell is completely different. | 0:07:41 | 0:07:45 | |
And, it struck me as, "Hey, I've seen giant tortoises in London Zoo, | 0:07:45 | 0:07:49 | |
"but there's nothing like that." | 0:07:49 | 0:07:51 | |
You can see this uprising neck, tiny little beady eyes, | 0:07:53 | 0:08:00 | |
and that shape would not work on the Continent. | 0:08:00 | 0:08:02 | |
Some jaguar would get in and just rip it apart, but in this Eden-like atmosphere of Galapagos, | 0:08:02 | 0:08:08 | |
it doesn't need the protection any more. | 0:08:08 | 0:08:10 | |
The shell's 1mm thick, just enough to hold it together so it doesn't | 0:08:10 | 0:08:13 | |
fall in two halves on the trail. | 0:08:13 | 0:08:15 | |
The last living tortoise on Pinta was recorded in 1906. | 0:08:20 | 0:08:25 | |
After that, only bones were found. | 0:08:25 | 0:08:28 | |
Until, that is, in 1971, a visiting snail scientist happened to recount | 0:08:28 | 0:08:33 | |
the details of his collecting trip to tortoise expert Peter Pritchard. | 0:08:33 | 0:08:38 | |
I was talking about saddle-back tortoises and adaptations for certain kinds of islands and, | 0:08:40 | 0:08:44 | |
he said, "Well, you know the tortoise we saw last week on Pinta | 0:08:44 | 0:08:48 | |
"wasn't really very saddle-backed." | 0:08:48 | 0:08:50 | |
I said, "What did you say?" | 0:08:50 | 0:08:52 | |
I just about dropped my teeth. He said, "We were in Pinta doing snails | 0:08:52 | 0:08:56 | |
"and this tortoise came out, | 0:08:56 | 0:08:57 | |
"and it was only one we saw, so I took a picture of it". I said, "Can I see the picture?" | 0:08:57 | 0:09:02 | |
This one photo brought a species thought to be extinct back to life. | 0:09:03 | 0:09:10 | |
Inspired by this evidence of a living Pinta tortoise, | 0:09:10 | 0:09:13 | |
the National Park authorities immediately sent out a search party. | 0:09:13 | 0:09:17 | |
This, the only footage ever taken of a tortoise on Pinta, | 0:09:42 | 0:09:46 | |
was recorded by Peter Pritchard who, | 0:09:46 | 0:09:48 | |
keen to share in this remarkable discovery, had followed | 0:09:48 | 0:09:52 | |
the Park Rangers out to the island. | 0:09:52 | 0:09:55 | |
By the time I arrived, they had found Lonesome George, | 0:09:55 | 0:09:59 | |
and he was tied up by one leg, | 0:09:59 | 0:10:01 | |
hobbling around on the little area just behind the coast, | 0:10:01 | 0:10:04 | |
and waiting to be taken away. | 0:10:04 | 0:10:07 | |
He was taken to the National Park headquarters on Santa Cruz Island | 0:10:27 | 0:10:32 | |
for safe-keeping. | 0:10:32 | 0:10:33 | |
News of his discovery spread far and wide. | 0:10:33 | 0:10:37 | |
And he became the most famous tortoise in the world. | 0:10:37 | 0:10:40 | |
I mean, anyone who knows about tortoises or Galapagos | 0:10:40 | 0:10:43 | |
knows about Lonesome George. | 0:10:43 | 0:10:45 | |
Lonesome's story brought the plight of the Galapagos tortoises | 0:10:48 | 0:10:52 | |
to the attention of the world, at a time when there was growing concern | 0:10:52 | 0:10:56 | |
about the impact of man on nature. | 0:10:56 | 0:10:58 | |
Yet, despite this, the natural riches of the Galapagos | 0:10:58 | 0:11:01 | |
continued to be plundered. | 0:11:01 | 0:11:03 | |
Nowhere are those riches more vivid than under the waves. | 0:11:05 | 0:11:10 | |
This is one of the most productive tropical marine ecosystems in the world. | 0:11:10 | 0:11:15 | |
The impact of local fishermen on this marine life had always been small. | 0:11:19 | 0:11:25 | |
Fishing was primarily for subsistence | 0:11:25 | 0:11:28 | |
as the islands' remote location meant there was no external market. | 0:11:28 | 0:11:33 | |
But, in 1989, there was a change in the fishermen's fortunes. | 0:11:33 | 0:11:37 | |
A market suddenly opened for a rather unlikely catch - | 0:11:37 | 0:11:41 | |
the sea cucumber. | 0:11:43 | 0:11:45 | |
These animals are a delicacy in the Far East. | 0:11:45 | 0:11:48 | |
They're cooked in soups and considered to be an aphrodisiac. | 0:11:48 | 0:11:51 | |
Asian buyers arrived in Galapagos, offering large amounts of cash to anyone who could supply them. | 0:11:53 | 0:12:00 | |
Fishermen used to earning a few hundred dollars a year could | 0:12:00 | 0:12:03 | |
earn several thousand in a day, just by picking the defenceless animals up off the sea floor. | 0:12:03 | 0:12:09 | |
The sea cucumber bonanza changed the islands forever. | 0:12:13 | 0:12:18 | |
Hundreds of fishermen from the Continent streamed into the islands. | 0:12:18 | 0:12:23 | |
Soon, they were harvesting up to a million animals every week. | 0:12:23 | 0:12:27 | |
Within a few years, the sea cucumbers had all but disappeared. | 0:12:27 | 0:12:31 | |
It was time for the National Park authorities to step in. | 0:12:31 | 0:12:35 | |
They set quotas and imposed size restrictions, | 0:12:38 | 0:12:41 | |
and not just for sea cucumbers, | 0:12:41 | 0:12:44 | |
but for all marine resources - lobster numbers were also in rapid decline. | 0:12:44 | 0:12:49 | |
They had the authority to confiscate illegal catches, | 0:12:49 | 0:12:53 | |
while legal catches were validated | 0:12:53 | 0:12:54 | |
with their stamp of approval - the image of Lonesome George. | 0:12:54 | 0:12:59 | |
This was the first time the National Park had seriously | 0:13:01 | 0:13:04 | |
concerned itself with the day-to-day affairs of the Galapagan people, | 0:13:04 | 0:13:08 | |
and not everyone was pleased. | 0:13:08 | 0:13:10 | |
The fishermen demonstrated against ever tighter restrictions, | 0:13:12 | 0:13:16 | |
complaining they could no longer make a basic living. | 0:13:16 | 0:13:19 | |
They vented their anger against the National Park, | 0:13:22 | 0:13:26 | |
even burning an effigy of the park's director. | 0:13:26 | 0:13:30 | |
In the year 2000, the National Park buildings on Isabela Island | 0:13:30 | 0:13:35 | |
were comprehensibly trashed. | 0:13:35 | 0:13:37 | |
Scrawled on the walls were threats to the lives of the staff who worked here. | 0:13:39 | 0:13:45 | |
Ever since the National Park got involved with sea cucumber fishery, | 0:13:53 | 0:13:56 | |
there has been tension between them and the fishermen. | 0:13:56 | 0:13:59 | |
They've even received death threats to their icon, Lonesome George. | 0:13:59 | 0:14:04 | |
"The National Park authorities and other conservation bodies are more | 0:14:14 | 0:14:17 | |
"concerned with the welfare of the animals than the people." | 0:14:17 | 0:14:20 | |
That's the claim of the leaders of the local fishing co-operatives. | 0:14:20 | 0:14:23 | |
To try and address this, the National Park host regular meetings | 0:14:49 | 0:14:54 | |
with the fishermen to discuss how to manage the marine environment. | 0:14:54 | 0:14:58 | |
How to provide for the fishermen, yet still uphold the ban on sea cucumber collecting. | 0:14:58 | 0:15:03 | |
There's much talk of finding alternative employment for the fishermen. | 0:15:03 | 0:15:07 | |
Titi Rendon is Head of the Santa Cruz fishing co-operative. | 0:15:07 | 0:15:11 | |
One of the problems for both the park and the fishing co-operative | 0:15:38 | 0:15:42 | |
is enforcing the regulations so that the marine life can recover. | 0:15:42 | 0:15:46 | |
Having decimated the lobster and sea cucumber fisheries, | 0:16:15 | 0:16:18 | |
some fishermen with no alternative employment available | 0:16:18 | 0:16:21 | |
are now turning their attention to another lucrative catch. | 0:16:21 | 0:16:25 | |
Sharks are being targeted, butchered for their fins. | 0:16:35 | 0:16:40 | |
There are worrying parallels with the sea cucumber boom. | 0:16:43 | 0:16:46 | |
The shark fins are sold for vast sums to the Far East | 0:16:51 | 0:16:55 | |
where they're used to thicken ceremonial soup. | 0:16:55 | 0:16:58 | |
This is strictly illegal. | 0:16:58 | 0:17:00 | |
Galapagos has one of the best set of laws to protect | 0:17:00 | 0:17:03 | |
marine life in the world, but these laws simply can't be enforced. | 0:17:03 | 0:17:08 | |
Just as with sea cucumbers, it's "grab what you can before it's gone". | 0:17:08 | 0:17:13 | |
Shark numbers are already in decline. | 0:17:31 | 0:17:34 | |
It's been predicted the sharks | 0:17:34 | 0:17:36 | |
of Galapagos will have all but disappeared in ten years. | 0:17:36 | 0:17:40 | |
Removing these top predators is also damaging | 0:17:46 | 0:17:50 | |
one of the world's most spectacular underwater ecosystems. | 0:17:50 | 0:17:54 | |
There are likely to be knock-on effects right through the food chain. | 0:17:55 | 0:17:59 | |
It's not just the damage to marine life that is a cause for concern. | 0:18:03 | 0:18:07 | |
The Galapagos Islands are regularly voted the best dive destination in the world. | 0:18:09 | 0:18:14 | |
For all the underwater wonders, there is one star attraction. | 0:18:19 | 0:18:24 | |
Every diver dreams of seeing live sharks. | 0:18:24 | 0:18:27 | |
Diving is the fastest-growing sector of the largest industry | 0:18:34 | 0:18:38 | |
in the Galapagos - tourism. | 0:18:38 | 0:18:40 | |
Killing one of tourism's top attractions | 0:18:44 | 0:18:47 | |
is undermining the very industry that could provide employment | 0:18:47 | 0:18:51 | |
for out-of-work fishermen. | 0:18:51 | 0:18:53 | |
It's in the interests of the tourist sector to limit the damage | 0:18:53 | 0:18:58 | |
being done by the fishermen. | 0:18:58 | 0:19:00 | |
One of the biggest dive operations is owned by Herbert Frey. | 0:19:00 | 0:19:05 | |
Whether all those involved can be persuaded to abandon shark finning, | 0:19:52 | 0:19:56 | |
in favour of a new life in tourism, remains to be seen. | 0:19:56 | 0:20:00 | |
What's certain is the tourist sector is well aware | 0:20:00 | 0:20:03 | |
of the need for better protection of the wildlife it depends on. | 0:20:03 | 0:20:07 | |
Cause celebre for the conservation movement, Lonesome George | 0:20:07 | 0:20:12 | |
has been embraced by a tourism industry keen to show its support | 0:20:12 | 0:20:15 | |
for the protection of the wildlife. | 0:20:15 | 0:20:19 | |
Almost every tourist shop sells souvenirs bearing his image and name. | 0:20:19 | 0:20:24 | |
Lonesome George has achieved celebrity status. | 0:20:24 | 0:20:27 | |
He's on the itinerary of every single visitor, | 0:20:29 | 0:20:33 | |
and is presented as living proof | 0:20:33 | 0:20:35 | |
of what can go wrong when humans invade this fragile paradise. | 0:20:35 | 0:20:39 | |
But not one tourist will ever visit his homeland, Pinta Island. | 0:20:44 | 0:20:50 | |
It's off limits. In fact, it's so little visited | 0:20:50 | 0:20:53 | |
that for a long time, hope survived that there might be more tortoises | 0:20:53 | 0:20:58 | |
hiding on the island, and with good reason. | 0:20:58 | 0:21:01 | |
A few years after the discovery of Lonesome George, this shell | 0:21:01 | 0:21:05 | |
was found by scientists visiting Pinta. | 0:21:05 | 0:21:08 | |
The shell beside me here is of great interest, | 0:21:08 | 0:21:11 | |
because this is a Pinta tortoise and it's an empty shell, | 0:21:11 | 0:21:14 | |
but it's with scutes on, and they fall off when the animal's been dead | 0:21:14 | 0:21:18 | |
for a year or so. | 0:21:18 | 0:21:20 | |
So, when that animal was collected and brought into this controlled | 0:21:20 | 0:21:23 | |
environment, it hadn't been dead for probably more than a year. | 0:21:23 | 0:21:27 | |
And it was found on Pinta two or three years after Lonesome George was found. | 0:21:27 | 0:21:31 | |
So there was more poking around there. | 0:21:31 | 0:21:35 | |
Peter Pritchard planned a final and exhaustive search of Pinta | 0:21:38 | 0:21:43 | |
in the hope more tortoises were hiding on the wild and remote island. | 0:21:43 | 0:21:47 | |
So this was a systematic transecting of the vegetative parts of Pinta. | 0:21:49 | 0:21:55 | |
But they found no sign of a living tortoise. | 0:21:57 | 0:22:01 | |
We found 15 skeletons of tortoises in... | 0:22:03 | 0:22:08 | |
none killed by man as far as we can tell. | 0:22:08 | 0:22:11 | |
They were all in deep ravines, which the tortoises fell in and could | 0:22:11 | 0:22:15 | |
not escape, and the bones were lying there in the bottom of the ravine. | 0:22:15 | 0:22:19 | |
The crew was not used to gathering bones - it's not part | 0:22:21 | 0:22:25 | |
of their standard marching orders, | 0:22:25 | 0:22:27 | |
but I said, "Look, fellas, this is Pinta. | 0:22:27 | 0:22:30 | |
"No-one else is making any more of these things. | 0:22:30 | 0:22:32 | |
"We've got to gather these bones up". We rounded up everything, from used plastic food bags to my underwear, | 0:22:32 | 0:22:40 | |
to whatever else you could find, to parcel these things up. | 0:22:40 | 0:22:44 | |
And we got them back here, | 0:22:44 | 0:22:46 | |
and they're boxed up in the reference collection in the Darwin station now. | 0:22:46 | 0:22:51 | |
There was something strange about these bones. | 0:22:53 | 0:22:56 | |
All but one of the 15 skeletons were from male tortoises. | 0:22:56 | 0:23:00 | |
It seems the final blow to the Pinta tortoise was a lack of females. | 0:23:00 | 0:23:06 | |
Exactly what happened on Pinta Island that led to the disappearance | 0:23:09 | 0:23:13 | |
of the female tortoises will never be known. | 0:23:13 | 0:23:16 | |
It happened a long time ago. | 0:23:16 | 0:23:19 | |
The animals in the ravines were old ones. | 0:23:19 | 0:23:20 | |
They had walked around 100 years before they fell into that ravine and died in the bottom of it. | 0:23:20 | 0:23:26 | |
And sometimes we'd find skeletons of three animals mixed in one ravine. | 0:23:26 | 0:23:29 | |
So it's a damn odd way to go - | 0:23:30 | 0:23:34 | |
extinct by masculinisation and falling into potholes. | 0:23:34 | 0:23:37 | |
It's not the normal pattern. | 0:23:37 | 0:23:39 | |
But I think it's what happened on Pinta. | 0:23:39 | 0:23:41 | |
Lonesome George may never have met a female tortoise on Pinta. | 0:23:47 | 0:23:52 | |
Now, any hope of introducing him to one has gone and, with it, | 0:23:52 | 0:23:56 | |
the chance of baby Pinta tortoises. | 0:23:56 | 0:23:59 | |
But there's no reason he shouldn't enjoy other female company, | 0:23:59 | 0:24:02 | |
and the next best thing - | 0:24:02 | 0:24:05 | |
perhaps father their offspring. | 0:24:05 | 0:24:08 | |
Lonesome's lack of interest in his female companions has sparked a lot of comment in the outside world. | 0:24:50 | 0:24:57 | |
There have been rumours he doesn't really know what to do! | 0:25:00 | 0:25:04 | |
It's even been suggested that perhaps George is gay! | 0:25:06 | 0:25:10 | |
But maybe all he needs is a helping hand. | 0:25:10 | 0:25:14 | |
Graciela Cevello was approached by an official | 0:25:17 | 0:25:20 | |
of the National Park with a special assignment. | 0:25:20 | 0:25:23 | |
The hope was if they could collect sperm and freeze it, | 0:25:55 | 0:25:59 | |
one of the females could be artificially inseminated. | 0:25:59 | 0:26:02 | |
Graciela did succeed in arousing George, but he never obliged with any sperm. | 0:26:59 | 0:27:04 | |
Eventually the project was abandoned | 0:27:07 | 0:27:09 | |
and George returned to his solitary ways. | 0:27:09 | 0:27:13 | |
Every failed attempt to reproduce Lonesome | 0:27:16 | 0:27:19 | |
builds to the unavoidable conclusion - | 0:27:19 | 0:27:22 | |
decades ago, and without anyone really noticing, | 0:27:22 | 0:27:26 | |
the Pinta Island tortoise passed the point of no return. | 0:27:26 | 0:27:30 | |
But for a miracle, when Lonesome George dies, his race dies with him. | 0:27:32 | 0:27:38 | |
It may be too late to save the Pinta tortoise, but in the corral | 0:28:17 | 0:28:22 | |
next door to Lonesome are tortoises that were rescued in the nick of time. | 0:28:22 | 0:28:27 | |
These tortoises were also the last of their kind. | 0:28:27 | 0:28:33 | |
They're the only ones found by an extensive search of Espanola Island in the mid-'60s. | 0:28:33 | 0:28:39 | |
Their fate would have been the same as Lonesome George, | 0:28:44 | 0:28:48 | |
but for the fact there are 15 of them - three males and twelve females. | 0:28:48 | 0:28:53 | |
For such ponderous animals, they can be remarkably frisky. | 0:28:56 | 0:29:01 | |
They're also remarkably fertile. | 0:29:04 | 0:29:07 | |
If mating is successful, | 0:29:07 | 0:29:08 | |
a female tortoise will dig a hole in the ground and lay up to 20 eggs. | 0:29:08 | 0:29:14 | |
Fausto is not only caretaker of Lonesome George, but also head | 0:29:18 | 0:29:23 | |
of this captive-breeding programme, | 0:29:23 | 0:29:25 | |
and he and his team have achieved spectacular success. | 0:29:25 | 0:29:29 | |
These three-month-old babies will be fed and sheltered under Fausto's | 0:29:39 | 0:29:43 | |
watchful eye until big and strong enough to fend for themselves. | 0:29:43 | 0:29:48 | |
The plan is then to return them to their native Espanola Island. | 0:29:48 | 0:29:53 | |
Following this success, tortoise breeding programmes were | 0:29:59 | 0:30:03 | |
established for other tortoise populations on other islands. | 0:30:03 | 0:30:08 | |
Isabela Island is by far the largest in Galapagos. | 0:30:08 | 0:30:12 | |
It has five distinct tortoise populations on five volcanoes. | 0:30:12 | 0:30:17 | |
This central volcano | 0:30:23 | 0:30:25 | |
is home to the largest population in the archipelago. | 0:30:25 | 0:30:29 | |
They number several thousand animals. | 0:30:29 | 0:30:32 | |
Because they live in these inaccessible heights, | 0:30:34 | 0:30:37 | |
they escaped the ravages of the 18th- and 19th-century sailors. | 0:30:37 | 0:30:41 | |
The two southern populations didn't fare so well. | 0:30:43 | 0:30:47 | |
Incidents of illegal tortoise hunting and eating still occur today. | 0:30:50 | 0:30:55 | |
It's thought this is the work of disgruntled fishermen sending | 0:30:56 | 0:31:00 | |
a grisly message to the National Park. | 0:31:00 | 0:31:03 | |
A new breeding centre was established by the National Park | 0:31:10 | 0:31:14 | |
to rescue the two southern populations of Isabela tortoises. | 0:31:14 | 0:31:18 | |
Oscar Carvajal runs the breeding programme. | 0:31:22 | 0:31:26 | |
Though troubled by the continuing hunting, Oscar is concerned by a more insidious | 0:31:26 | 0:31:31 | |
danger facing the tortoises - | 0:31:31 | 0:31:34 | |
another legacy of man's arrival on these once pristine islands. | 0:31:34 | 0:31:39 | |
Goats are perfectly adapted to the arid Galapagos climate. | 0:32:06 | 0:32:12 | |
They will feed on almost anything, and have an incredible capacity to reproduce. | 0:32:12 | 0:32:17 | |
Introduce a few animals onto an island, and after a few years | 0:32:17 | 0:32:21 | |
there will be several thousand. | 0:32:21 | 0:32:24 | |
Goats are the biggest threat to tortoises on most of the islands, | 0:32:28 | 0:32:33 | |
including Isabela. | 0:32:33 | 0:32:35 | |
They strip the vegetation bare, leaving nothing for the tortoises to eat. | 0:32:35 | 0:32:40 | |
Giant tortoises evolved, in the absence of mammals, | 0:32:45 | 0:32:49 | |
as the principal herbivore on the Galapagos Islands. | 0:32:49 | 0:32:52 | |
They simply cannot compete with the fleet-footed, | 0:32:52 | 0:32:56 | |
rapidly reproducing goats. | 0:32:56 | 0:32:58 | |
The National Park decided this severe problem | 0:32:58 | 0:33:01 | |
needed a radical solution. | 0:33:01 | 0:33:04 | |
Helicopters and sharp-shooters | 0:33:27 | 0:33:29 | |
flown in from New Zealand patrolled 400,000 hectares | 0:33:29 | 0:33:34 | |
of goat-infested island - a landscape denuded | 0:33:34 | 0:33:37 | |
by the insatiable pests. | 0:33:37 | 0:33:39 | |
There were 100,000 goats on northern Isabela alone. Now there are none. | 0:33:56 | 0:34:02 | |
It's the first time such a large-scale mammal eradication project | 0:34:02 | 0:34:07 | |
has achieved such success. | 0:34:07 | 0:34:09 | |
The value of goat eradication is certainly not lost on Fausto. | 0:34:55 | 0:35:00 | |
The latest generation of offspring from the 15 Espanola tortoises | 0:35:00 | 0:35:05 | |
rescued from the wild are almost ready for release onto their native island. | 0:35:05 | 0:35:09 | |
They're weighed and measured | 0:35:11 | 0:35:13 | |
and will then be quarantined for two months. | 0:35:13 | 0:35:16 | |
Their return to Espanola will be timed to coincide | 0:35:16 | 0:35:20 | |
with the rainy season, to ensure there is vegetation for them to eat. | 0:35:20 | 0:35:24 | |
Espanola is a small, uninhabited and sparsely vegetated island | 0:35:30 | 0:35:34 | |
in the south of the archipelago. | 0:35:34 | 0:35:37 | |
This island, like Isabela, was once over-run with goats, but not any more. | 0:35:39 | 0:35:45 | |
The island's small size made the goat cull here | 0:35:45 | 0:35:49 | |
a much easier prospect than on Isabela. | 0:35:49 | 0:35:51 | |
The last goat was shot in 1978 and since then, Fausto has been bringing | 0:35:51 | 0:35:57 | |
baby tortoises back to Espanola. | 0:35:57 | 0:36:00 | |
With their island free of goats, the future of Espanola's tortoises ought to be assured. | 0:37:07 | 0:37:13 | |
But that's not the end of the story. | 0:37:13 | 0:37:15 | |
The National Park have received threats from angry fishermen that | 0:37:15 | 0:37:20 | |
goats might at any time be released back onto the remoter islands. | 0:37:20 | 0:37:24 | |
And there are other threats far harder to pinpoint and deal with | 0:37:26 | 0:37:30 | |
that affect not just tortoises but all the endemic species. | 0:37:30 | 0:37:34 | |
They arise from the very source that some have hailed as the salvation of the animals of the Galapagos. | 0:37:34 | 0:37:40 | |
Three planes a day fly in from the mainland. | 0:37:45 | 0:37:49 | |
Visitors from all around the world arrive, eager to see for themselves | 0:37:51 | 0:37:56 | |
the remarkably tame wildlife in this apparently pristine archipelago. | 0:37:56 | 0:38:01 | |
But the endless stream of people | 0:38:01 | 0:38:03 | |
has brought to an end the islands' isolation. | 0:38:03 | 0:38:07 | |
The isolation that was for so long | 0:38:07 | 0:38:10 | |
the Galapagos wildlife's best protection from human disturbance. | 0:38:10 | 0:38:14 | |
The tourists could be endangering the wildlife they've come to see. | 0:38:14 | 0:38:19 | |
The endemic animals have evolved largely free from competition or disease. | 0:38:20 | 0:38:26 | |
This leaves them especially vulnerable to any germs the visitors might be inadvertently carrying. | 0:38:26 | 0:38:31 | |
Giant tortoises have been dying from a type of influenza, | 0:38:37 | 0:38:41 | |
similar to that found in humans. | 0:38:41 | 0:38:44 | |
Verna Cedeo is head of a new genetics lab set up in Galapagos | 0:38:48 | 0:38:53 | |
to help with conservation, | 0:38:53 | 0:38:55 | |
identifying potential biological threats to the wildlife and seeking solutions. | 0:38:55 | 0:39:00 | |
The tortoise has to be immobilised before its health check. | 0:39:04 | 0:39:08 | |
This tortoise is one of a population living | 0:39:08 | 0:39:14 | |
in the highlands of Santa Cruz, | 0:39:14 | 0:39:19 | |
the island with the highest human population and greatest number of visiting tourists. | 0:39:19 | 0:39:24 | |
So far, the tortoise numbers are not being seriously affected by the virus. | 0:39:24 | 0:39:30 | |
This monitoring is to make sure the situation doesn't get any worse. | 0:39:31 | 0:39:37 | |
But the threat from disease is a serious one. | 0:39:37 | 0:39:41 | |
Although the tortoises of Santa Cruz may be safeguarded for now, | 0:40:18 | 0:40:22 | |
very worrying results are coming to light in studies of another iconic Galapagan creature. | 0:40:22 | 0:40:28 | |
Darwin's finches, so named because they are said to have inspired | 0:40:32 | 0:40:37 | |
the great naturalist's theory of evolution, are a group of 13 species | 0:40:37 | 0:40:41 | |
of birds endemic to the islands. | 0:40:41 | 0:40:44 | |
Each species has a unique role within the islands' ecology. | 0:40:44 | 0:40:49 | |
Sarah Huber has been investigating a population of these birds | 0:40:53 | 0:40:58 | |
in the highlands of Santa Cruz above the main town of Puerto Ayora. | 0:40:58 | 0:41:03 | |
She has uncovered a potential disaster. | 0:41:05 | 0:41:09 | |
These maggots are the larvae of a parasitic fly. | 0:41:12 | 0:41:16 | |
They literally eat the nestlings alive. | 0:41:16 | 0:41:19 | |
As you get more and more parasites, their feeding holes become bigger and | 0:41:19 | 0:41:23 | |
you actually get these large holes in the body cavity. | 0:41:23 | 0:41:26 | |
If the parasite is prevalent throughout the entire island, and | 0:41:26 | 0:41:31 | |
we see rates of mortality like this on the entire island, then chances of extinction are very likely. | 0:41:31 | 0:41:38 | |
These Darwin's finches, famous for bringing the idea of evolution | 0:41:40 | 0:41:44 | |
to life, are following Lonesome George down the road to extinction. | 0:41:44 | 0:41:50 | |
The parasite, I guess, came from mainland Ecuador. | 0:41:50 | 0:41:53 | |
Nobody really knows how it got over. | 0:41:53 | 0:41:56 | |
Speculations are that it came with food or other, you know, on a boat or an airplane. | 0:41:56 | 0:42:02 | |
The port of Puerto Ayora, | 0:42:04 | 0:42:06 | |
capital of the tourism industry, is constantly buzzing with activity. | 0:42:06 | 0:42:10 | |
Everyday, boats are bringing goods from the mainland to provide for | 0:42:13 | 0:42:17 | |
the tourists, and all the people who work in the tourist industry. | 0:42:17 | 0:42:22 | |
Every boat carries the risk of alien species hiding among the cartons of fruit and veg. | 0:42:22 | 0:42:27 | |
And the flow of goods is only set to increase. | 0:42:27 | 0:42:31 | |
Tourism in Galapagos is growing by 10% every year. | 0:42:32 | 0:42:38 | |
The sleepy fishing town of Puerto Villamil on Isabela, | 0:42:40 | 0:42:45 | |
former centre of the sea cucumber fishery, is already preparing for a fresh economic boom. | 0:42:45 | 0:42:51 | |
A new airport will be receiving flights directly from the mainland by the end of the year. | 0:42:52 | 0:42:57 | |
The islanders are busy getting ready for a flood of visitors. | 0:42:59 | 0:43:02 | |
New hotels and restaurants | 0:43:02 | 0:43:04 | |
are going up all over town. | 0:43:04 | 0:43:08 | |
The boom in tourism is driving a boom in immigration. | 0:43:11 | 0:43:15 | |
The resident population of Galapagos is increasing by 6% every year. | 0:43:19 | 0:43:24 | |
After all, tourism has made these islands one of Ecuador's richest provinces. | 0:43:24 | 0:43:31 | |
But once here, the immigrants also feel the pressure of so many people. | 0:44:03 | 0:44:08 | |
Puerto Ayora is rapidly filling every corner of space set aside | 0:44:29 | 0:44:34 | |
for the town by the National Park. | 0:44:34 | 0:44:37 | |
The buildings are going up to house people drawn in from the mainland | 0:44:37 | 0:44:42 | |
to fill jobs created by the ever-expanding tourism industry. | 0:44:42 | 0:44:46 | |
Tourism and consequently population growth is spiralling out of control. | 0:44:46 | 0:44:52 | |
One thing is for sure, tourism is here to stay. | 0:45:36 | 0:45:40 | |
To limit the risk of introducing alien species and disease, there | 0:45:40 | 0:45:44 | |
need to be major changes to the way tourism is managed and supported. | 0:45:44 | 0:45:48 | |
The flood of imports to feed the tourists, for example, | 0:45:48 | 0:45:51 | |
needs to be minimised, and that means food self-sufficiency. | 0:45:51 | 0:45:56 | |
There is little established agriculture on Galapagos. | 0:45:56 | 0:46:00 | |
A large acreage of the verdant highlands was | 0:46:00 | 0:46:02 | |
cleared by early settlers before the National Park was ever created, | 0:46:02 | 0:46:06 | |
but this was just for cattle. | 0:46:06 | 0:46:08 | |
Now these pastures hold the potential for a self-sustainable archipelago, if the problems | 0:46:10 | 0:46:16 | |
of growing vegetables organically on these soils can be ironed out. | 0:46:16 | 0:46:22 | |
The organisation Fundar Galapagos | 0:46:22 | 0:46:26 | |
aims to promote new ways of life for the islanders. | 0:46:26 | 0:46:30 | |
Self-sufficiency would clearly reduce the volume of imports, | 0:47:14 | 0:47:19 | |
but it requires the acceptance of fewer exotic goods by local people, | 0:47:19 | 0:47:22 | |
especially by the stream of new arrivals who don't all appreciate | 0:47:22 | 0:47:26 | |
the need to live within sustainable limits. | 0:47:26 | 0:47:29 | |
Immigration is being driven by a demand for skilled labour. | 0:47:29 | 0:47:33 | |
A new generation of local residents need to be better qualified for | 0:47:53 | 0:47:57 | |
a life in tourism, if the influx of outsiders is to be stemmed. | 0:47:57 | 0:48:01 | |
One initiative is this cookery class established in the town's largest school. | 0:48:01 | 0:48:05 | |
The project is run by Chef Pablo Guerrero from one of the larger hotels. | 0:48:05 | 0:48:12 | |
The idea is not simply to teach the students haute cuisine, but to give them a better | 0:48:43 | 0:48:48 | |
understanding of why this place they live in is so special and why there | 0:48:48 | 0:48:53 | |
needs to be restrictions in place to preserve the islands. | 0:48:53 | 0:48:57 | |
There are many ways an educated and enlightened generation | 0:49:29 | 0:49:32 | |
of Galapagans could contribute to the protection of their islands. | 0:49:32 | 0:49:37 | |
Virna Cedea regularly invites school classes into her genetics laboratory | 0:49:37 | 0:49:42 | |
to give them an insight into conservation work within Galapagos. | 0:49:42 | 0:49:46 | |
A new generation of native islanders, appreciating conservation and the need to live sustainably, | 0:50:27 | 0:50:32 | |
who reject the mentality of "take what you can without regard for the future" | 0:50:32 | 0:50:38 | |
surely offer the best hope for the preservation of these islands. | 0:50:38 | 0:50:42 | |
The future of these islands really does lie with the people who live here. | 0:52:48 | 0:52:53 | |
If the people of Galapagos can pull together towards a shared goal | 0:52:53 | 0:52:57 | |
to preserve what is theirs, the crisis might yet be averted. | 0:52:57 | 0:53:02 | |
Galapagos is still the most pristine tropical archipelago in the world, | 0:53:04 | 0:53:09 | |
but it no longer enjoys the isolation that both shaped and preserved it. | 0:53:09 | 0:53:14 | |
It remains a global treasure, a unique Garden of Eden. | 0:53:14 | 0:53:18 | |
But a greater understanding of its fragility is needed, if its beauty and innocence is to be sustained. | 0:53:18 | 0:53:25 | |
The alternative is staring us in the face. | 0:53:30 | 0:53:34 | |
Like a ghost back from the grave, Lonesome George | 0:53:34 | 0:53:37 | |
is an ever-present reminder of the vulnerability of Galapagos wildlife. | 0:53:37 | 0:53:42 | |
Even though Lonesome was saved, the Pinta tortoise is effectively extinct. | 0:53:42 | 0:53:49 | |
But that's not the end of the story for Pinta Island. | 0:53:49 | 0:53:52 | |
The National Park hope to return it to the condition that existed | 0:53:52 | 0:53:56 | |
before the first human set foot there. | 0:53:56 | 0:53:59 | |
Central to this ambition, | 0:53:59 | 0:54:01 | |
and right next door to Lonesome, are the Espanola tortoises. | 0:54:01 | 0:54:06 | |
Genetic studies have revealed0 | 0:54:06 | 0:54:07 | |
they are the closest relation to Lonesome George, | 0:54:07 | 0:54:11 | |
making Espanola tortoises the most likely ancestors of those on Pinta. | 0:54:11 | 0:54:17 | |
But the two islands are at opposite ends of the archipelago, | 0:54:17 | 0:54:20 | |
which begs the question, how did the ancestors of Lonesome George | 0:54:20 | 0:54:24 | |
make it from Espanola all the way to Pinta? | 0:54:24 | 0:54:28 | |
It's probably 150 miles away, I wouldn't be surprised. | 0:54:28 | 0:54:32 | |
But if you look at the sweep of the Humboldt current coming up South America | 0:54:32 | 0:54:38 | |
and through the archipelago, | 0:54:38 | 0:54:40 | |
it sort of washes around Espanola and carries on up to Pinta. | 0:54:40 | 0:54:45 | |
So the tortoise wouldn't need to do any cross-current dynamic swimming. | 0:54:45 | 0:54:52 | |
It would just need to accidentally fall in the sea and survive a week | 0:54:52 | 0:54:56 | |
or two, bobbing around like a cork in the ocean, | 0:54:56 | 0:54:59 | |
because the same shell and the same thick skin that allow this animal | 0:54:59 | 0:55:03 | |
to survive where you and I would die | 0:55:03 | 0:55:06 | |
of thirst in two days, keeps the sea water out. | 0:55:06 | 0:55:09 | |
And the other good thing is, they have long necks, | 0:55:09 | 0:55:13 | |
so a normal tortoise would probably find its head under water | 0:55:13 | 0:55:17 | |
most of the time if it was floating at sea, | 0:55:17 | 0:55:21 | |
but these have a little periscope-like head. | 0:55:21 | 0:55:23 | |
They just have to have the luck and the lottery of life to wash up on Pinta. | 0:55:25 | 0:55:30 | |
Fausto is returning to Pinta Island for the first time in 30 years. | 0:55:40 | 0:55:45 | |
He is accompanied by a team of National Park Rangers and their hunting dogs. | 0:55:47 | 0:55:52 | |
They are here to to check that the island is free of goats. | 0:55:52 | 0:55:55 | |
The National Park officials are considering a plan to put Espanola tortoises onto Pinta Island. | 0:55:57 | 0:56:04 | |
Pinta is one of the remotest and least-visited islands | 0:56:15 | 0:56:18 | |
in the Galapagos. | 0:56:18 | 0:56:20 | |
Nobody has ever lived here, and tourists are forbidden from visiting these shores. | 0:56:20 | 0:56:25 | |
It remains one of the most untouched islands | 0:56:27 | 0:56:31 | |
in an archipelago itself heralded as the most pristine in the world. | 0:56:31 | 0:56:35 | |
The only major disturbances have been the slaughter | 0:56:38 | 0:56:41 | |
of the tortoises and introduction of three goats in the '50s. | 0:56:41 | 0:56:46 | |
Their 40,000 descendants were eradicated 20 years later | 0:56:46 | 0:56:49 | |
by Fausto and a team of rangers. | 0:56:49 | 0:56:52 | |
Now that the goats have gone, the island has no large herbivores, | 0:57:34 | 0:57:38 | |
the role once fulfilled by the ancestors of Lonesome George. | 0:57:38 | 0:57:43 | |
Thinking ecologically, you might want to put Espanola tortoises on Pinta, | 0:57:43 | 0:57:47 | |
just to make the ecology complete. | 0:57:47 | 0:57:51 | |
And possibly even repeat the evolutionary experiment that led | 0:57:51 | 0:57:55 | |
from Espanola to Pinta tortoises | 0:57:55 | 0:57:56 | |
at some fairly remote time in the past. | 0:57:56 | 0:58:00 | |
Give it another try. | 0:58:00 | 0:58:01 | |
See if the island shapes them the same way. | 0:58:01 | 0:58:04 | |
