Species composition of buried seeds in abandoned forests after clear-cutting, in which sika deer inhabit at high density, in the warm temperate zone were examined. Seedling emergence of 38 herbaceous species was confirmed by germination test. Of the herbaceous species, Erechtites hieracifolia and Macleaya cordata were co-dominant species. Seedlings of 6 woody species, Broussonetia kazinoki, Prunus jamasakura, Rubus crataegifolius, Rubus hirsutus, Callicarp sp., Weigela floribunda were also observed. Buried seed bank would play a certain role of forest vegetation recovery in abandoned forests after clear-cutting, although soil erosion due to loss of forest vegetation by excessive deer browsing and disturbance by walking diminished species richness of buried seeds.
