  1. DBH, diameter at breast height. The division of DBH classes followed ref. 36. No juvenile and only one premature tree was found in the three low-density population sites, suggesting chance for seedlings in the low-density sites to reach the juvenile, premature or mature stage was very low, although more newly germinated seedlings survived in the low-density sites than in the abundant sites and per-capita survivorship at the low-density sites was also higher than at the abundant sites.
