Tree-ring descriptive statistics for four conifer species from Jiuzhaigou National Nature Reserve used in dendroclimatological analyses.

*Mean sensitivity is the average of the relative difference in widths of adjacent rings for all cores [34].†Inter-series correlation is the average of all correlation for all series (cores) within a chronology or species.Pinus tabuliformis and Larix potannii are considered pioneer, shade intolerant species. Picea purpurea and Abies fargesii are more shade tolerant and can be found in old-growth forest. Statistics were produced by COFECHA during cross-dating.
