We surveyed the population structures and dynamics of Q.
chungii in Minqing Huangchulin National Nature Reserve located in
Fujian Province, China (26°15′29″ N ~ 26°22′41″ N,
118°39′38″ E ~ 118°51′19″ E, with an elevation range of
100 ~ 595 m). This area has the most intense
distribution of Q. chungii in the world (Li et al.
2010). The reserve was specifically established to conserve Q.
chungii and its associated communities and ecosystems (Li et
al. 2010). The reserve has a mid-subtropical maritime monsoon climate,
with an average annual temperature of 17.5°C, an average annual sunshine
duration of 1,871.4 hours, a frost-free period of 294 days, and an
average annual precipitation of 1,400 to 1,900 mm. The forest soil is
predominantly mountainous red soil (Li et al. 2010).
