- Observation Seed rain seed categories differed significantly; worm-eaten seeds were 19.44 times germinated seeds.
- 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 Animal damage affected 45.90% of seeds.
- Observation The soil seed bank contained seeds of 69 species.
