As one of the structural and dynamic analyses of plant communities using life-forms, the pollination type specturum was applied to various stages of succession from the pioneer to the climax. Self-pollination (S) and apogamous (A) types shown in Table 1 are relatively important in stages immediately after denudation, and then wind pollination type (W) gradually increases in pioneer stages. In the forest with its canopy of W, insect (I) and bird pollination (B) types increase their dominance in the understory.
