Other claims from this paper (12)
- Observation Seed rain lasted about two months and averaged 12.44 seeds m-2.
- Observation Seed rain peaked in late November to early December.
- Observation Worm-eaten seeds made up 53.79% of the soil seed bank.
- Observation Perfect seeds in the soil bank were 2.15 seeds m-2 fewer than in seed rain.
- Observation Germinated seeds in the soil bank were 0.20 seeds m-2 fewer than in seed rain.
- Observation Seed survival rate was 13.51%.
- Observation Animal damage affected 45.90% of seeds.
- Observation The soil seed bank contained seeds of 69 species.
- Observation Germinable seeds had very low density and were mostly buried at 2~5 cm.
- Observation Seedling density was very low in the natural forest.
- Association Seed characteristics and habitat were closely related to low seedling density.
- Mechanism Animal damage, decay and abortion hinder long-term seed persistence and natural regeneration.
