Table 2. Descriptive statistics of dendrochronology. Control indicates the non-treated area, while Thin 1 and Thin 2 express the areas with different frequencies of thinning on numbers. Three indices explain the statistical explanation of dendrochronology. R_bar and EPS represent Inter-series correlation and Expressed Population signal, respectively.

Area	Rbar	Mean sensitivity	EPS
Control	0.45	0.26	0.87
Thin 1	0.51	0.27	0.90
Thin 2	0.45	0.23	0.91
