Giant pandas (Ailuropoda melanoleuca) prefer to live in old forest which has never been logged, according to new research.
Looking at the habitat features most closely associated with the presence of giant pandas, the study, published in the journal Biological Letters, was based on data collected over five years in China’s Sichuan Province. As expected, bamboo was a key factor predicting the presence of giant pandas, as it forms the vast majority of their diet.
Importance of old-growth forest
However, the team also discovered that the presence of giant pandas was strongly linked to the age of the trees. Why old-growth forest is so important to the giant panda was unclear, but it may be that the bamboo growing beneath older trees is more nutritious, and easier for pandas to eat.
Another intriguing possibility is that only older trees grow large enough to form cavities in which female giant pandas can give birth. This raises the possibility that a lack of suitable ‘maternity dens’ may limit the giant panda population in areas which have a history of logging.
Protecting giant panda habitat
These important findings come ahead of a key decision by the Chinese government on whether to renew a logging ban which has been protecting giant panda habitat since 1998. The study concludes that it may be more cost-effective for the government to protect the existing old-growth forest than to open it up to logging while protecting an equivalent area of previously logged, secondary-growth forest.
With the protection of unlogged forest now shown to be as important to giant panda conservation as preserving areas of bamboo, it remains to be seen what the future will hold for these vital giant panda habitats.
