Various factors have contributed to pandas becoming endangered. Human urban development, as well as farming and forest clearing have basically restricted panda habitat to consist of the mountains in central China. In addition, pandas have also been hunted despite being illegal. Pandas cannot reproduce until they are between four and eight years of age. The female panda only ovulates once a year. It takes 95 to 160 days for the baby to be born, meaning she likely will only giver birth every other year or less. In addition, the lifespan of a panda is believed to be around 20 years old. This means the average female panda only has about a half a dozen times to get pregnant during her entire lifetime.

Pandas only feed on bamboo and the bamboo forests are decreaing rappidly. They can only reproduce when they are 4 or 8, and when the babies are born the mother often rolls on top of them, so many don't survive.

Giant pandas are known as "specialists," meaning they can survive and thrive in a very restricted set of conditions - food, water, shelter, etc. The opposite of a specialist is a "generalist," which would be an animal that can thrive in a wide variety of conditions (A good example of a generalist is a coyote - they can live in nearly any climate, eat almost anything, and are not easily affected by subtle or even major changes in their circumstances). This isn't a black and white distinction between animals, rather there is a broad range between the most specialized animals and the least. But on that scale, the Panda is on the extreme end of specialism. Specialism can be viewed as a significant evolutionary disadvantage. Climates change. Plant distribution changes. Competitive species move into new areas. These are facts of our dynamic planet and have been for millions of years. With the spread of humans across the planet in the last few thousand years, though, the pace of change has increased dramatically, leaving many species unable to adapt quickly enough. It is easy to see that this would affect extreme specialists, such as the giant panda, more accutely than other animals. The other answers given here, human encroachment, habitat destruction, and direct killing of pandas by humans, have been the direct cause of their endangerment. But it is important to point out that their own specialist nature made them vulnerable and unable to adapt to these changes. Most of these same pressures, and others, have been placed on nearly every mammal species on the planet, and some continue to thrive. For example, returning to my coyote example, many scientists believe there are more coyotes today than ever before.

The giant panda's numbers have been declining for thousands of years due to hunting by humans and climatic changes.The greatest present threat to the panda's survival is the loss of its habitat. Their range is steadily shrinking due to logging operations, fell trees, and peasants clearing the land for farming or harvesting vegetation for fuel. The panda's populations are already small and isolated, confined to high ridges and hemmed in by cultivation. Poaching was once a serious problem but has dropped off, and it is no longer considered a major problem in substantial portions of the range. Furthermore, pandas' body parts are no longer sought for use in traditional Chinese medicine. Giant pandas are, however, victims of snares set for musk deer by poachers. An indirect threat relates to the panda's reliance on bamboo for food. Bamboo stands are subject to periodic large-scale die-offs. In the past, when bamboo died off, pandas could migrate to areas with healthy bamboo. But a fragmented habitat makes this impossible. With better public education and awareness, the Panda's status as a Nation Treasure has helped to bring about a better understanding of it's endangered status as well. The Chinese Government has inacted harsher penalties for those that poach Pandas. I suppose part of the reason for the decline of the Giant Panda, aside from the intrusion of humans into their environment, could be due to their unique reproduction process. In the wild, the Giant Pandas do not reach sexual maturity until somewhere between the ages of four and a half years old till, in some cases, as old as seven and a half. In captivity it averages out to five and a half and six and a half years. During her heat, the female is only fertile between two to seven days. The number of young per litter is usually 1 or 2, very rarely she may have 3. However, a captive female will only raise 1 of these young even if more than one are born. Now and again a wild female might, on rare occasions, attempt to raise two. (Several instances of a female accompanied by 2 young have been reported from the Min and Qionglai Mountains.) The birth interval is 2 years. (Schaller et al. 1985) After a period of approximately 135 days, which is average (97-181 days) the babies are born helpless, like kittens, puppies, mice, etc. They are born with their eyes sealed and cannot maintain their own body temperature. Pandas have a unique ability to experience what is called Delayed Implantation, a process where the embryo will divide a few times and then stop developement, floating free within the uterus for a period of up to six months, after which it attaches itsefl to the uterine wall and continues it's developement. "Since a panda female may not produce her first offspring until the age of 7 years and probably raises only one young successfully every 3 years (a rate of 0.3 young per year), the population can sustain an annual total mortality rate no greater than about 8 % per year."Schaller et al. 1985) With low birth rate, habitat invasion, and reduced range, it is no wonder the Giant Panda is on the Endangered Species list. The lifespan of the Panda is still being researched. One animal lived to an age of about 34 years in captivity. The lifespan in the wild is still unknown.

Bacuse. i'm not completly sure. my memory isn't that great, but i had it on my oral exam in 10'th grade. There is this panda, the giant panda, that it only exist 6 of. and most of them live in china, maybe that's just out in the wild. But they are almost all gone.

Because they are very, very tasty

I'm not sure how much hunting has to do with it, but I do know that pandas are very inefficient eaters. They have to constantly eat the whole time they're awake and they still don't have any energy. What little energy there is in bamboo they don't even digest properly anyway. They conserve energy by just living alone, sitting still, eating. They avoid contact with other pandas becuase it causes to much excitement that they just can't afford. So perhaps they are dying out naturally? I'm not sure.

They kept mouthing off to tigers.

cause people distory their homes they live in trees and eat bamboo people are tearing those things down to build crap -.-; we should save the pandas and red pandas to :'( the red pandas are cute are endangered to! we must save them......

Chinese people ate them all.
