| Research Abstract |
Many forest fires have happened since about 30 years ago and regeneration of such burned forests go very badly.So we investigate the regeneration mechanism and the factors inhibiting regeneration of those forests.We sometimes found linear arrangements of trees in those forests. So we hit upon "Regeneration sheltered by fallen trees"hypothesis.We made field experiment on factors inhibiting regeneration in burned area to verify our hypothesis. The data indicates clearly three inhibiting factors, direct sunlight, shortage of seeds and litter. And we have the highest numbers of seed germination in the experimental site of northern side of raking and seeding area. In addition to these results, we found other many samples of "Regeneration sheltered by fallen trees" naturally growing up to sub-trees. From these two additional results, we verified our hypothesis. We made the manual that is useful to promote forest regeneration applying by our hypothesis.
