Results suggested that the nine trees were established in four distinctive periods, namely, in 1000~1100’s, 1200~1300’s, 1550’s, and 1750~1800’s. Radial growth chronologies exhibited a series of major to moderate releases about every 100 to 200 years. However, the asynchronous nature of these releases suggests that they were caused by a series of small-scale disturbances. Based on these results and the average growth rates of the first 10 and 20 years of the nine trees analyzed, it is believed that as a whole Taiwan yellow false cypress could maintain its local population via tree-replacement regeneration alone.
