Abstract:
The biomass variation of
Fargesia denudata in Tangjiahe Nature Reserve before and after feeding by giant pandas was investigated in order to discuss the impact of wild giant panda feeding on the biomass of its clonal population. After feeding, the dry material content of
F. denudate at different ages increased, and the dry material content of culms, branches and leaves in feeding plots was all higher compared to control plots. There is no significant difference in the biomass of various components of
F. denudata between the feeding plots and the control plots. At the individual level, the water content of
F. denudata decreased in both feeding and control plots after giant panda feeding. At the component level, however, the water content of one-year-old bamboo stems and two-year-old and perennial-year-old bamboo leaves of
F. denudata increased significantly after giant panda feeding.The results showed that wild giant panda feeding has little impact on the biomass of the clonal population of
F. denudata. The bamboo biomass can recover to its pre-feeding level through its own growth, thereby continuously providing food resources for giant pandas.
