Decline pattern of C. fargesii and seed traits

Widespread tree defoliation and mortality rates have increased considerably in recent decades. We investigated the decline pattern of Castanopsis fargesii and examined the effects on conspecific seedling regeneration. This dataset contains the basic characteristics and tree vigor level data of 617 C. fargesii individuals (H >1.3m, identified in nine plots in a national nature reserve in Chongqing in Southwestern China), and the seed traits data of the seeds produced by decline adult trees and non-decline adult trees.
