National Geographic Giant Pandas The Last Refuge

00:00:02 In remote mountains of central China
00:00:05 moisture borne on the monsoons
00:00:07 nurtures a forest world of isolation...
00:00:10 and mystery
00:00:16 Across ages
00:00:18 bamboo [Poaceae (family)] has flourished
00:00:21 erecting nearly impenetrable thickets
00:00:26 barriers against time
00:00:34 For nearly a decade
00:00:35 a Chinese scientist has
00:00:38 forest for one of the world's
00:00:50 Though its image is
00:00:52 the giant panda
00:00:54 kept its life in the wild hidden
00:01:18 For Professor Pan Wenshi
00:01:20 deciphering the panda's secret
00:01:23 The species clings
00:01:27 Only about
00:01:31 In captivity
00:01:32 pandas have not reproduced enough to
00:01:34 increase or even maintain
00:01:37 If the species is to be saved
00:01:40 we must understand and protect
00:01:43 the secret life of pandas in the wild
00:01:52 Now
00:01:57 In a mountain cave
00:01:58 a newborn panda is found...
00:02:01 permitting the first
00:02:04 and the first long-term
00:02:07 embarking on a remarkable life unlike
00:02:10 that of any creature on earth
00:03:04 The Qin Ling mountains...
00:03:06 rugged divide between northern
00:03:10 ...and one of the last retreats
00:03:18 Concealed by dense foliage
00:03:23 the panda is literally
00:03:26 In the panda's world
00:03:31 The clown-like mask elicits
00:03:35 But it's probably seen as
00:03:39 one of the panda's
00:03:49 Pandas are shy
00:03:53 When one is seen,
00:04:01 They are solitary animals...
00:04:04 But they are aware
00:04:07 keeping in touch by sound...
00:04:15 Their social lives consist largely
00:04:17 of reading and leaving scent marks
00:04:20 Rubbing its scent glands
00:04:23 a panda says "here I am"
00:04:32 By smell alone
00:04:33 pandas can tell the identity and
00:04:36 of a neighbor who may go unseen
00:04:42 Almost exclusively
00:04:46 Equipped with a unique sixth
00:04:50 pandas have been shaped by evolution
00:04:53 for this life-sustaining activity
00:05:04 They consume up to
00:05:07 [Bashania fargesii and
00:05:08 a day with great technique
00:05:10 But they're finicky about
00:05:13 They eat different parts of the bamboo
00:05:18 Sometimes they prefer the
00:05:21 while at other times it's the tough
00:05:27 It's a lot of word for little reward...
00:05:29 only about 17 percent is digested
00:05:37 So pandas must eat relentlessly
00:05:44 They eat till they're full
00:05:46 then sleep wherever they are
00:05:54 But young pandas
00:05:56 To survive they must learn
00:06:03 Seemingly vulnerable
00:06:05 the panda has endured while other more
00:06:07 formidable mammals have
00:06:14 Its margin of safety is narrow...
00:06:16 but for millions of years
00:06:21 Yet an understanding of how
00:06:24 has been as elusive as the animal itself
00:06:36 To unlock the panda's secrets
00:06:38 a former logging camp called Shashuping
00:06:41 now serves as a research station
00:06:44 From this base,
00:06:46 biology professor Pan Wenshi
00:06:49 more than sixty pandas
00:06:52 the first long-term study of
00:06:59 With Lu Zhi, former student
00:07:03 Pan has long hoped to discover
00:07:06 fragile in captivity
00:07:11 This knowledge could
00:07:17 After years of patient searching
00:07:20 Pan and Lu Zhi now suspect a birth
00:07:25 and set out on a
00:07:34 The treacherous slopes of
00:07:38 and perhaps explain why the existence
00:07:41 of giant pandas here was
00:07:54 A gentle approach...
00:08:02 In a cramped cave an adult
00:08:07 Cradled in her paws
00:08:17 Pan will find that a panda mother
00:08:19 devotes herself entirely to her newborn
00:08:22 She holds and soothes
00:08:26 neither leaving the den nor
00:08:41 Blind and helpless
00:08:45 at about four ounces it
00:08:52 Perhaps in part to prevent
00:08:55 the infant panda wields a voice
00:09:15 Professor Pan's hope is that
00:09:19 he can learn enough to
00:09:22 of the past involving pandas
00:09:28 A panda was not seen alive
00:09:32 when a cub named Su Lin
00:09:37 Though Su Lin would
00:09:40 it was love at first sight
00:09:44 The public craved more pandas
00:09:48 The sudden fad was called
00:09:59 The panda was immediately beloved
00:10:01 but poorly understood...
00:10:03 treated as if the living animal
00:10:10 ...And the toy arrived without
00:10:14 Keepers could only
00:10:16 Nearly half died within five years
00:10:24 As a result of our enchantment
00:10:26 one in ten of the world's remaining
00:10:29 pandas lives in captivity today...
00:10:31 among the most popular
00:10:45 The dream has been to breed pandas
00:10:47 in captivity for release into the wild
00:10:50 but arranged matings
00:10:54 The result has been a record of more
00:10:58 Even in a more
00:11:01 in a Chinese panda reserve
00:11:02 successful reproduction
00:11:06 A female can conceive
00:11:10 In captivity males are
00:11:13 in part because they lack
00:11:30 Loud love songs frequently lead to
00:11:59 Even when young are produced
00:12:01 their chances of survival are bleak
00:12:03 In the past three decades
00:12:05 nearly 60 percent have died
00:12:11 Despite intense care
00:12:19 So far, it has not been possible to breed
00:12:21 a self-sustaining panda
00:12:25 For the species to survive
00:12:29 But time and habitat
00:12:35 A panda homeland that once stretched
00:12:38 across southern Asia from
00:12:41 Beijing has shrunk under human
00:12:45 unconnected areas
00:12:47 For about 240 wild pandas
00:12:49 the slopes of the Qin Ling
00:13:04 By fitting pandas with radio collars
00:13:08 professor Pan and Lu Zhi
00:13:11 to track the pandas in their
00:13:15 ...and locate them easily
00:13:34 Theirs is an unprecedented bond
00:13:38 Never before have wild pandas wild pandas
00:13:41 become so accustomed to
00:13:49 "For nine years in Qin Ling
00:13:50 Lu Zhi and I have lived
00:13:54 We drink water from the
00:13:56 and we have stayed together
00:14:00 They are familiar
00:14:02 These pandas
00:14:11 Lone pandas are
00:14:14 But will a mother be so trusting if they
00:14:17 attempt to visit the

00:14:32 feeds some distance
00:14:39 She has stayed away
00:14:42 may be dead erasing
00:14:45 and another life in a lineage
00:15:02 Their fears prove unfounded
00:15:28 Pan knows his time to inspect
00:15:32 Too long in the den and
00:15:34 despite their efforts to
00:15:36 the mother could react violently to
00:15:38 their presence here and attack them
00:15:49 They usually observe
00:15:53 but they must sometimes
00:15:56 panda closely to document its growth
00:16:07 It's a female...
00:16:10 In the years to come
00:16:12 she may bear cubs of her own
00:16:14 permitting study of
00:16:26 At seven weeks
00:16:30 Her eyes are
00:16:34 Her expanding repertoire of
00:16:38 still browsing nearby
00:17:02 Pan is heartened by what he finds
00:17:07 with a stomach full of mother's milk
00:17:28 Time is up
00:17:30 The baby must be returned quickly
00:17:36 In the weeks to come
00:17:37 Pan and Lu Zhi make
00:17:41 When her cub is weeks old
00:17:43 a wild mother leaves it to
00:17:47 In the past
00:17:49 this natural behavior was
00:17:52 and many cubs were
00:17:55 only to die later in human care
00:18:09 This all began with a boyhood dream
00:18:12 of adventure in
00:18:18 "When I was in high school
00:18:20 I read Jack London's books
00:18:22 Among the books,
00:18:26 "White Fang"
00:18:33 Form then on
00:18:35 I dreamed of living in remote areas like
00:18:37 western America or Alaska
00:18:41 Living in the wild
00:18:44 that was my early dream
00:18:56 The years have turned early
00:19:00 Pan spends months of each year
00:19:04 paying some research expenses
00:19:07 working late hours
00:19:10 in a tiny cubicle that
00:19:26 Pan's other world offers
00:19:29 The rest of the year
00:19:32 sprawling symbol of
00:19:36 Here Pan is a biology professor
00:19:41 His work was mainly
00:19:44 and the panda had their
00:20:08 "Um, after graduating
00:20:11 when I was 25years old,
00:20:13 I had the opportunity to
00:20:15 um, to go visit
00:20:17 um, the Beijing Zoo
00:20:19 where they had the first
00:20:24 And that was the first time
00:20:28 and it was very interesting

00:20:32 and that was when
00:20:35 devote my whole

00:20:42 city of Xi'an
00:20:46 Her name is Dan-Dan...
00:20:48 a reference to her reddish-brown
00:20:51 She is one of only three
00:20:56 Pan and Lu Zhi think
00:20:59 a throwback to prehistoric times
00:21:02 Pandas may have developed their black
00:21:04 and-white coloration
00:21:10 Finding Dan-Dan ill
00:21:12 Pan and Lu Zhi brought her
00:21:16 hoping she would be

00:21:21 who was himself
00:21:23 Sixties during the Cultural Revolution
00:21:34 "The Cultural Revolution
00:21:37 No one dared to
00:21:39 Because I told the truth
00:21:41 they put me in jail
00:21:42 beat me and pulled my hair
00:21:44 I thought:
00:21:46 is to insist
00:21:49 After 56 days of beatings and
00:21:56 "Overcoming this
00:21:59 basis for my conviction as
00:22:07 In a Beijing classroom
00:22:08 Pan carries his campaign on behalf of
00:22:11 pandas to a
00:22:17 Using props made from the skins
00:22:22 Pan teaches about the
00:22:39 His stories evoke surprise
00:22:41 The children thought pandas
00:22:48 Pan wants to inspire understanding
00:22:53 that will probably
00:22:57 In a country to nearly
00:23:01 with urgent human needs
00:23:08 Even some friends cannot understand
00:23:12 and family several times a year
00:23:40 the trip south to the Qin Ling mountains
00:23:44 22 hours by train
00:24:09 For Pan, this journey retraces
00:24:14 the panda before advancing waves of human settlements
00:24:19 The last stands of wilderness
00:24:21 like the last pandas
00:24:26 at the highest edges of existence
00:24:32 For years, Professor Pan
00:24:37 But they have now attracted
00:24:40 who staff the Qin Ling research
00:24:59 To Pan, they hold promise that the
00:25:04 And they have been
00:25:08 an adventure that has
00:25:12 "There were many difficulties
00:25:15 We always felt cold
00:25:20 Lu Zhi got frostbite
00:25:23 and Ding Qian had
00:25:40 Mid-December
00:25:42 Four months
00:25:44 birthing season
00:25:47 Cubs are now old enough to
00:25:50 and are sometimes
00:25:52 while their mothers
00:26:03 Face to face with humans,
00:26:05 the cub seems by turns
00:26:34 To symbolize her importance
00:26:37 the two researchers have decided to
00:26:39 name her Xi Wang-meaning "Hope"
00:26:43 The christening
00:26:46 who may sleep 20 hours a day
00:26:48 even when guests are present
00:26:55 Easy slumber
00:26:58 Nearby, her mother unwinds from
00:27:11 Xi Wang seems vulnerable
00:27:14 But animal predators pose
00:27:18 A panda pelt can bring poachers
00:27:22 and dozens of panda cubs have
00:27:26 by well meaning
00:27:28 or wanted to believe
00:27:37 Xi Wang is still nursing
00:27:39 which will dominate her life
00:28:01 A surprise...
00:28:04 The mother returns
00:28:06 Xi Wang to a new den
00:28:10 But for Pan and Lu Zhi
00:28:14 Despite years of observation
00:28:16 they have seldom seen two pandas
00:28:18 even mother and young
00:28:26 Touched by her devotion
00:28:28 they call the mother Jiao-Jiao
00:28:35 In Pan's study area
00:28:38 only one farm has persevered in the
00:28:39 harsh altitudes of panda territory
00:28:43 En route back
00:28:46 who count themselves
00:28:53 Pan has heard reports that a panda
00:28:57 It behaved as though ill
00:29:00 Have the Lis seen it?
00:29:14 They have,
00:29:16 and were surprised to encounter
00:29:23 In a chill are rain at
00:29:26 Professor Pan and his team are
00:29:33 Villagers have sent word that a wild
00:29:36 panda has appeared on a doorstep
00:29:38 Pan thinks it may be
00:29:43 The scientists are puzzled
00:29:46 wild pandas to come to human dwellings when ill...
00:29:50 an enigma in a creature
00:29:56 Though they are neighbors
00:29:58 few in the village have
00:30:02 Beneath corn [Zea mays] dried
00:30:06 the creature huddles
00:30:07 The animal appears old
00:30:33 Pan asks if the panda
00:30:36 It has not
00:30:37 The man discovered it whimpering...
00:30:51 Suspecting a digestive problem
00:30:53 Pan decides to treat the
00:31:01 It proves no easy task to relocate
00:31:17 At Shashuping research station
00:31:19 therapy begins with
00:31:25 Weighing the old panda's good
00:31:29 the students call him
00:31:36 Already, his appetite is returning...
00:31:42 Antibiotics and vitamins mixed in honey
00:31:46 meal quickly revive Lucky's spirit
00:31:49 In ancient texts
00:31:50 a creature believed to be the panda was
00:31:53 known as "the iron-eating beast"
00:31:57 ...because it chewed up
00:32:00 ...and it still tries to
00:32:13 Lucky, it turns out, has
00:32:17 and an indiscriminate palate
00:32:26 Eventually
00:32:30 to retrieve this unusual delicacy
00:32:38 In Shashuping's field lab
00:32:40 Lu Zhi adds samples
00:32:43 growing collection from
00:32:51 Through genetic analysis
00:32:53 she seeks to learn how much
00:32:56 In a hundred years, she fears all
00:32:58 Qin Ling pandas could
00:33:01 This could cause extinction through
00:33:04 harmful mutations and
00:33:07 "There is a critical question:
00:33:13 then how much and
00:33:18 This work, we hope
00:33:22 and then we'll find
00:33:33 Recovered after
00:33:36 Lucky is ready
00:33:46 Pan is hopeful
00:33:48 but the scientists know Lucky
00:33:51 may be too old to
00:34:02 Weeks later
00:34:05 Again ill
00:34:06 Lucky will be taken
00:34:09 where he will die
00:34:21 In the bitter cold
00:34:23 while other Qin Ling animals
00:34:29 Enslaved by the need to
00:34:32 pandas continue to
00:34:48 Pan and Lu Zhi have learned to respect
00:34:51 the panda's tough constitution
00:34:53 Thick, oily fur and bulky
00:34:57 and they seem immune
00:34:59 For Xi Wang, snow is just
00:35:26 Now a five-month-old toddler
00:35:28 she seems dimly aware
00:35:32 In the months to come
00:35:33 they will offer her only safety from
00:35:35 predators in her mother's absence
00:35:42 But to hide in a tree
00:35:44 Xi Wang must
00:35:57 For now, baffled by the challenge
00:36:09 For those who would study pandas
00:36:11 winter in the Qin Ling
00:36:15 The cold is relentless...
00:36:26 Days and nights pass
00:36:30 a dwelling heated only by wood fire
00:36:33 lit only by candle and lantern
00:37:16 As winter drags on
00:37:18 Jiao-Jiao begins to take Xi Wang
00:37:23 The ancient Chinese
00:37:26 in such scenes of tranquility
00:37:29 According to one account
00:37:31 retiring armies waved not a
00:37:40 For Xi Wang
00:37:46 Success brings not only safety
00:38:47 As winter gives way to spring
00:38:49 the panda's realm
00:38:52 reawakens with sound and color
00:39:04 By may
00:39:08 At nine months
00:39:10 she continues to nurse
00:39:12 but
00:39:13 like human babies
00:39:15 she investigates
00:39:23 For Jiao-Jiao
00:39:25 spring brings not only the
00:39:28 but the seasonal agony of ticks
00:39:31 and leeches [Hirudinea (class)]
00:39:41 Xi Wang will watch her mother from
00:39:45 until she's ready to join her
00:39:57 Once tentative,
00:40:01 sometimes showing greater
00:40:20 Jiao-Jiao seems concerned
00:40:24 especially when succulent
00:40:38 For both, life is serene
00:41:01 They look awkward
00:41:02 but pandas are deceptively agile
00:41:04 their joints so flexible
00:41:08 and perform gymnastic routines
00:41:55 Clear-cut harvesting
00:41:58 is the paramount threat
00:42:02 Food and cover dwindle
00:42:04 Populations are further isolated
00:42:09 Panda ranges have
00:42:11 only two decades...
00:42:27 A billion people in China need
00:42:32 In fifty years
00:42:36 Over the years
00:42:38 Professor Pan has
00:42:40 invade 70 percent
00:42:54 He asks how far the
00:42:59 Next spring, they will cut
00:43:02 the slopes now roamed
00:43:10 To penetrate the panda's forest
00:43:12 new roads must be blasted
00:43:32 By most standards
00:43:33 the operations are crude
00:43:35 sometimes conducted
00:43:38 that mixes gun powder with cigarettes
00:43:44 Industrial safety is a recent
00:43:46 but despite accidents
00:43:48 the work goes on relentlessly
00:44:20 Risking all
00:44:22 Pan has pleaded with authorities
00:44:25 With stubborn insistence
00:44:27 despite threats and harassment
00:44:29 he has succeeded
00:44:31 The government has halted the timber
00:44:33 cutting in the
00:44:46 An excursion to check
00:44:48 now outfitted with a radio collar...
00:44:54 It is mid-October
00:44:55 At fourteen months
00:44:57 Xi Wang is passing
00:45:08 Something is amiss
00:45:10 The signals lead to
00:45:13 Expecting Xi Wang
00:45:26 Pan believes Jiao-Jiao tore the
00:45:37 He suggests they search
00:45:42 But Jiao-Jiao's signal is weak...
00:45:44 ...They will have to separate
00:46:02 Xi Wang is invaluable to science
00:46:04 She has been monitored since birth
00:46:06 and has provided
00:46:10 But for Pan and his crew
00:46:32 Following his instincts
00:46:34 Pan comes to a steep ravine...
00:46:37 Barely visible among the foliage
00:46:39 sitting casually in a tree
00:46:41 the familiar shape of Xi Wang
00:47:08 To re-establish contact
00:47:10 they must sedate
00:47:15 They must act now
00:47:18 But her perch above a cliff
00:47:24 The tranquilizing
00:47:27 the pain to be inflicted slight
00:47:29 But the moment is
00:47:33 whose lives are dedicated
00:47:50 Several minutes pass as
00:47:54 They pray she won't fall
