The beekeepers in Shennongjia National Park, central China's Hubei Province, collect honey from hives nestled atop steep cliffs. They say they do not move the hives for easier and safer access because the cliffs protect the hives from predators. Experts say the population and habitats of Asian honeybees reduced sharply in the 20th century due to environmental changes and the introduction of Western honeybees. The unique climatic and geographic conditions make Shennongjia a sanctuary for Asian honey bees and more than 1,000 kinds of nectar.
