Tree Census Data

The Paosh plot is 6-ha, rectangle shape with 200 m X 300m. All living trees larger than 5 cm in DBH (diameter at breast height) have been censused since 1994 (Hoshizaki et al. 2004; Niiyama et al. 2003). Meteorological variables monitored using the tower (Kosugi et al. 2008) (triangle mark in Figure 1)
