"Pandas are found in different kinds of forests in China," said the study's lead author, Wei Wei, an associate professor at China West Normal University. "Old growth forests provide large tree cavities for den sites, but pandas living in forests without these large old trees must use cave dens instead. We studied the microclimates inside these den habitats, and found that tree dens were better at buffering against extremes of temperature and humidity than cave dens -- indicating that tree dens provide a more stable microclimate for rearing cubs."
The study was conducted with support of the National Natural Science Foundation of China, the State Forestry and Grassland Administration of China, the Ministry of Science and Technology of the People's Republic of China, and San Diego Zoo Global.

"Current monitoring practices for giant pandas and their habitat do not include systematic surveys of large old trees, but our data points to the possibility that these trees are critical...
