Michelia compressa is a broad-leaved species with high economic values. Past studies on M. compressa emphasized physiology, timber characteristics, and so on. Studies on population structure and natural regeneration of the tree species are rare. In this study, a plot was laid out in stand No. 57-1, 3rd forest compartment, Xitou area in the Experimental Forest, National Taiwan University. Distribution of DBH classes for Cryptomeria japonica, which is the main tree species, was bell-shape, but it was L-shape for M. compressa. This suggests that number of M. compressa seedlings are numerous, but only few individuals grow into small trees.
