The growth and development of environmental protection forests on the Yokohama National University campus was reported in this Bulletin (Miyawaki & Fujiwara 1988). In February 1992 a follow-up survey of the growth and development of environmental forests on the Yokohama National University campus was done at the permanent quadrat sites. The site condition, especially drainage, was the most important factor during the first six years (Miyawaki & Fujiwara 1988). After six years, planted individuals prepare the environment well and smaller trees grow two times bigger on the area with bad drainage. Planted trees on the slope still grow well, but they grow 1.5 times more than before. In the forest, after ten years, the individual growth rates of the diameter at breast height were quarter than growth rates of tree height. Also species growth rates are different from before.
