12 To study the availability of secondary forest for giant pandas (Ailuropoda melanoleuca), we 13 conducted a field survey on the primary and secondary forests in Wanglang Nature Reserve. We 14 compared these two forests based on species diversity and community structure using variance 15 analysis and Mann-Whitney U-test. Results showed that, as compared with the primary forest, the 16 secondary forest had more woody plant species, higher tree richness, smaller tree size, smaller 17

The secondary forest could provide 18 enough food, species composition, and large-tree environment for giant pandas just as the primary 19 forest does. Importantly, the secondary forest could provide more of the giant pandas' preferred food 20 than the primary forest, which might be the reason why giant pandas are increasingly using the 21 secondary forest habitat. Thus, we consider the secondary forest as a viable habitat for giant pandas. 22
