Other claims from this paper (9)
- Association Fire increased similarity between locations in species composition.
- Association The strength of the fire effect on similarity increased with fire severity.
- Observation Paulownia seeds were dispersed up to 3.5 kilometers from mature individuals.
- Observation Paulownia seeds are killed by all but the least severe fires unless protected by burial.
- Observation Buried Paulownia seeds show very limited germination even under only 2 cm of soil without litter.
- Mechanism Invasion is controlled by the yearly seed rain rather than by seed accumulation in the seedbank.
- Observation Habitat models show Paulownia range restriction over time as high light and low competition conditions disappear with increasing native cover.
- Observation Paulownia habitat is maintained along cliff margins and narrow, shallow soiled benches.
- Observation No significant correlation was found between Paulownia presence or cover and native species cover or diversity.
