At about 1 week they begin to develop their distinctive black and white markings and at about 5 to 7 weeks, they start to open their eyes. The mother holds the cub to her chest, much like a human mother.
In size, compared to their mothers, panda cubs are some of the smallest newborns. In the wild, Giant Pandas nest in hollow tree trunks or caves. In captivity, they are then raised by caretakers using incubators in the nurseries at the Giant Panda Reserves or Zoos. At the Giant Panda Reserves, the caretakers in the nursery leave one cub with the mother for her to care for and place one in the nursery in an incubator. In the nursery, the staff will hand feed the cub and stay with it 24 hours a day, every day.
The mother accepts both babies, but only one at a time. This process of exchanging the cubs, which was developed at the Wolong Panda Center, allows both of the cubs to survive in captivity. Older Giant pandas spend most of their time eating or sleeping. Younger ones like to play. They play with other Giant Pandas, running, chasing each other, climbing trees, and tumbling on the ground.
They are well suited to their environment. They can swim in the mountain streams and enjoy the winter snow. Today the Giant Panda is limited to the mountains in a few Chinese provinces in southwestern China. Their range is along the eastern rim of the Tibetan Plateau. Giant Pandas do not have a permanent den and do not hibernate. In the winter they will seek shelter in hollow trees. Giant Pandas typically have a range of km but can travel up to 10 km a day looking for food, water, and shelter.
The Giant Panda has lived for centuries in coniferous forests with dense undergrowth of bamboo at elevations of 5, to 11, feet. Rain or dense mist throughout the year shrouds these remote forests in heavy clouds. In the winter snow is common. Today, these forests are under attack by dramatic increases in human population. Agriculture, ranching, logging, trapping, and human settlement dramatically threaten their habitat. Previously, they lived at lower elevations but farming and clearing of the forest have pushed them higher into the mountains.
Bamboo grows under the shade cover of the large fir trees. Logging and clearing the land for agricultural uses is a major factor in the reduction of bamboo. The impact of rapid population growth has seen the destruction of significant Giant Panda habitat. In an effort to defend the Giant Panda, the Chinese government enforces a logging ban in the Giant Panda reserves. The 8. In the s, the Chinese government began conservation efforts to protect pandas.
In the first panda reserve was established in southern China. Pandas were classified as an endangered species in the s.
Today there are 40 Giant Panda reserves in China. These reserves need to be connected via corridors in order to reduce isolation and fragmentation of the Giant Panda population. Villages and human activities now block open ranges for migration. The fragmentation of Giant Panda areas is a major problem affecting mating. Another problem related to the fragmentation of the Giant Panda areas is that the bamboo will flower and then die off about every 20 years. When this occurs the Giant Pandas need to migrate to a new area.
There have been reports of Giant Pandas starving when they are unable to find bamboo in new areas. The May 12th earthquake epicenter was just a few miles from the Wolong Panda Center. Aftershocks continued for days. In one 24 hour period aftershocks were monitored in the quake zone. There were approximately 70, deaths from the quake, 20, missing and , injured.
Five staff members of the Wolong Nature Reserve were killed. One Giant Panda, Mao Mao was killed by the collapse of the exterior wall in her enclosure.
Wild Giant Pandas certainly died as a result of the earthquake but no estimates as to the number are available. Several Giant Pandas came down from the mountains in search of food. One wild Giant Panda has starved due to the destruction of the bamboo. The consequences of the devastation to the bamboo as a result of the earthquake will continue for many years. A study in by the Chinese Department of Forestry estimated the current population of the wild Giant Pandas at approximately 1, As of there are approximately giant pandas in captivity.
The U. While hunting and poaching have been reduced due to strict laws by the Chinese government, accidental capture of giant pandas in traps set for other animals still possess a serious problem.
The future of the giant panda is interwoven with the Chinese people. New advances in environmentally responsible farming, high yield crops to reduce logging, and population control efforts will all help the giant pandas. The Chinese Government also has several projects for reforesting hillsides, protecting grasslands and nature reserves for the giant pandas.
There are also plans to pay farmers to turn cropland back to forests and to establish commercial tree farms to replace logging.
Bamboo planting, in Sichuan Province, for the captive and wild pandas is an ongoing project. Pandas live in around 20 isolated habitats red in Gansu, Sichuan and Shaanxi provinces, China. Minshan Mountains. The mountains form a natural barrier between the densely populated southern and eastern provinces of China and the great wilderness of the Tibetan Plateau, the highest and largest in the world.
Spreading through the provinces of Sichuan and Gansu, the Minshan mountains run along the north of the Great Sichuan plain and to the east of the Tibetan Plateau, and form part of one of the most important watersheds in China. They are also home to hundreds of giant pandas with PingWu county boasting the highest density of wild pandas in the world. But the Minshan mountains' magnificent forests are a critical habitat not only for giant pandas but also for a wealth of other species, including the dwarf blue sheep and beautiful multi-coloured pheasants.
Qinling Mountains. The mountains are part of China's most critical watershed, channeling rainwater into both of the country's great rivers, the Yangtze and the Yellow.
Located in Shaanxi Province, the Qinling mountains form a natural barrier between northern and southern China, protecting the south from the cold northern weather.
And the warm rains on the southern slopes support a rich variety of plants and animals. Along with a few hundred pandas, the mountains are also home to other endangered species, including the golden monkey, takin and crested ibis.
Female pandas ovulate only once a year, in the spring. A short period of two to three days around ovulation is the only time a giant panda is able to conceive. Calls and scents draw males and females to each other. Female giant pandas give birth from 90 to days after mating. Although females may give birth to two young, usually only one survives.
Giant panda cubs may stay with their mothers for up to three years before striking out on their own. This means that a wild female, at best, can produce young only every other year.
In a lifetime, a giant panda may successfully raise only five to eight cubs. The giant pandas' naturally slow breeding rate prevents a population from recovering quickly from illegal hunting, habitat loss and other human-related causes of mortality. At birth, a giant panda cub is helpless, and it takes considerable effort on the mother's part to raise it. A newborn cub weighs ounces and is about the size of a stick of butter. Except for a marsupial, such as a kangaroo or opossum, a giant panda baby is the smallest mammal newborn relative to its mother's size.
Cubs do not open their eyes until they are weeks old and are not mobile until they are 3 months old. A cub may nurse for eight to nine months and is nutritionally weaned at 1 year old, but not socially weaned for up to two years.
In the wild, giant pandas typically nap between feedings for two to four hours at a time, snoozing on their side, back, or belly, either sprawled or curled up. While a giant panda is resting, it continues to defecate. The number of droppings at a rest site can be used to gauge the relative amount of time a giant panda spent at that site.
During a short rest of less than two hours, there are five to ten droppings. Eleven to 25 droppings often accompany rests lasting longer than two hours.
Most rest periods are two to four hours in duration but may increase to six or more hours during the summer months. Scientists are not sure how long giant pandas live in the wild, but they are sure it is shorter than lifespans in zoos. They estimate that lifespan is about years for wild pandas and about 30 years for those in human care. Chinese scientists have reported zoo pandas as old as The largest threat to giant panda survival is habitat destruction.
People in need of food and income have cleared forests for agriculture and timber. This logging has fragmented a once continuous habitat, leaving small groups of pandas isolated from each other. When populations become small, they are extremely susceptible to extinction due to environmental or genetic influences, such as drought or inbreeding. Small populations cannot rebound the same way large populations do; as groups of pandas become more isolated, it is more likely that reproduction, disease resistance and population stability will be threatened.
For more than 40 years, the Zoo has celebrated these charismatic bears by creating and maintaining one of the world's foremost panda conservation programs. In that time, the Zoo's team — consisting of dozens of animal care staff, scientists, researchers, international collaborators and conservationists — has made great strides in saving this species from extinction by studying giant panda behavior, health, habitat and reproduction.
Specifically, it has allowed scientists at the Smithsonian's National Zoo and Conservation Biology Institute to learn about panda estrus, breeding, pregnancy, pseudopregnancy and cub development — work that is shared around the world with other institutions that also care for and breed this vulnerable species. See a history and timeline of giant pandas at the Zoo here.
Much has been learned since that time, but there still remains much more to learn. With the arrival of Tian Tian and Mei Xiang, the Zoo has developed a ten-year research plan that will hopefully culminate in a growing, thriving population of giant pandas.
Some research areas will repeat behavioral observation studies on Tian Tian and Mei Xiang in order to increase sample size and determine whether a behavior pattern is common to giant pandas or particular to an individual.
In other areas, such as reproductive biology, the advanced techniques scientists use today largely did not exist when Ling-Ling and Hsing-Hsing were alive. Also, opportunities for research and conservation initiatives in the wild, including the potential for increasing the wild giant panda population in China through reintroduction, are greater today than at any time in the past. However, these plans and initiatives will be costly to carry out, as will China's official National Plan for the Conservation of Giant Pandas and their Habitats.
Scientists from the Smithsonian Conservation and Biology Institute's Center for Conservation Genomics, have become adept at studying the genetic relatedness of pandas in human care. Chinese colleagues maintain an up-to-date studbook of these vulnerable animals.
Zoo scientists developed the formula used to make breeding recommendations for the entire giant panda population in human care, ensuring that it is genetically healthy. Scientists are working to preserve 90 percent of the genetic diversity of the giant panda population in human care. Panda breeding season is a race against the biological clock.
It only comes once a year, and the giant panda team, including scientists from the Smithsonian Conservation Biology Institute's Center for Species Survival, and vets, keepers and biologists from the Zoo's animal care teams, must be ready. Giant panda females, like Mei Xiang, ovulate for just 24 to 72 hours. To identify the opening of that tiny window, animal keepers carefully watch Mei Xiang for any behavioral sign of estrus. At the same time, scientists monitor hormones in her urine to pinpoint the window when she is ready to breed.
If attempts at natural breeding are not successful, scientists can step in, collect fresh or frozen-thawed semen from a male and use the genetic material collected to artificially inseminate a female.
Under the terms of the Zoo's agreement with China, scientists at the Smithsonian Conservation Biology Institute's Conservation Ecology Center have studied these bears both in the wild and in human care.
Smithsonian Conservation Biology Institute ecologists spend months in China every year studying wild pandas and their neighbors, such as Asiatic black bears and takin. They teach colleagues in China how to conduct censuses and surveys of large mammals, including giant pandas that live in the wild, using geographic information systems GIS and other high-tech tools for tracking wildlife. They are also working to identify new landscapes for giant panda reintroduction.
Field research has revealed that wild pandas' habitat is highly fragmented, which means pandas have a difficult time finding a mate.
