Pandas' Natural Habitat Must Expand, Experts Warn

Isolated populations, like land-bound species on islands, have no way to escape disaster, said Loucks. Populations ravaged by forest fires, famines, or other catastrophes have nowhere else to go. In contrast, pandas living in much larger forest reserves can move to other habitable areas.

"There are sections of the remaining forest where giant pandas have been extirpated," said John Seidensticker, a conservation scientist at the Smithsonian National Zoological Park in Washington D.C. "This shows the danger posed to pandas of continual fragmentation of the remaining habitat in this mountain system."

Forest Fixer-Upper

Using a combination of satellite images and other remote sensing methods, conventional maps, and data collected on the ground, Loucks and colleagues created maps showing the remaining suitable panda habitat in the Qinling Mountains. Pandas are fussy eaters, primarily feeding on just two species of bamboo. The researchers found that the current network of nature reserves covers less than 50 percent of the remaining bamboo-harboring woodland.

"There's plenty of bamboo-rich habitat free of pandas," said Loucks. "Expanding reserves and linking up protected habitat patches would encourage pandas to take advantage of these resources."

The study calls for the creation of three new reserves and several protected "corridors" of habitat to link up isolated patches.

Not a lot was known about pandas when the reserves were first created, said Loucks. Research since the 1970s has shown that the pandas migrate between a higher elevation bamboo species in summer and a lower elevation species in winter. Scientists say such information needs to be considered when designating new protected areas.

Government in Action

The Chinese government has already begun making changes above and beyond those recommended in the study, which was conducted in 2000.

Five new reserves and five new habitat corridors have been designated in Qinling. A busy mountain road responsible for carving one protected area in two has been redirected underground.

"When China decides to build something, it gets built fast," said Loucks.

The changes suggested for the Qinling reserves could also usefully be applied to ensure the survival of pandas in the other five mountain ranges.

"[The proposals], if adopted, will stem the fragmentation, enhance connectivity of habitat, and assure the necessary degree of habitat integrity to meet the needs of giant pandas in the future," said Seidensticker. "Analyses such as this provide the road map that can give the most conservation impact for the least investment [and] assure a place for wild giant pandas in the future."

Pandas are also reaping the benefits of measures adopted recently by the Chinese government to control severe flooding.

After catastrophic flooding of the Yangtze River and its tributaries in 1998, authorities took action to prevent future disasters. Logging has been banned in many flood-susceptible areas until 2010, and financial incentives are encouraging reforestation on the steep sides of the mountains that have been converted to agriculture. It's likely that these habitats will support bamboo given enough time, said Loucks.

"The indirect effects are pretty influential for panda conservation," he said.

Tonight on National Geographic Today: With less than 1,000 left in the wild, and only about 150 in captivity, pandas are one of the most critically endangered species on Earth, and a worldwide symbol of conservation. But the panda is also a tremendously powerful cultural symbol in China. Monday, learn why this black and white bear has remained an historical icon in China, and what this graceful giant represents to Chinese society today.

Tomorrow: While there are many around the world who are deeply concerned with the future of giant pandas, the Chengdu Research Base is the site of one of the most successful efforts in all of China to raise them. Take an inside look at this captive breeding program as National Geographic Today correspondent Patty Kim reports from a reserve where giant pandas are raised in captivity to ultimately be reintroduced into the wild.

Wednesday: The most crucial conservation efforts for pandas take place inside and outside of China's cities and villages. In its schools, efforts to educate the Chinese are essential and begin at an early age. See what lessons kindergartners are learning about endangered species and the importance of conservation. And, out in the forests of China, there is another critical link in conservation efforts: large reforestation programs with the goal of improving the future for many of China's most endangered species.

Thursday: Planning a trip halfway around the world takes careful planning, especially when the travelers are two giant pandas! National Geographic Today takes you behind the scenes as Le Le and Ya Ya get ready to head from China to their new home at the Memphis Zoo. Get an inside look at what logistics, veterinary care, and potential complications must be tended to when undertaking such an incredible feat. And, talk about precious cargo! Join National geographic Today correspondent Patty Kim and her crew as they climb aboard a FedEx plane with two 150-pound (70-kilogram) giant pandas for an exclusive look at how these beautiful creatures traveled to their new home at the Memphis Zoo—one that bears a striking resemblance to their Chinese habitat. With the only television crew to travel with these giant creatures, National Geographic Today brings you exceptional coverage of this amazing journey.
