Other claims from this paper (19)
- Observation Common and rare Persoonia species had high seed dormancy without fire.
- Observation Common and rare Persoonia species had low seed mortality without fire.
- Observation Persoonia germination occurred only at sites burned in late 2001.
- Intervention effect Persoonia germination was significantly higher after medium intensity fire than after low intensity or partial burns.
- Observation None of the postfire Persoonia seedlings survived to October 2002.
- Association Fire effects became more uniform at larger site scales as intensity increased.
- Observation The first fire produced 473 P. mollis subsp. nectens seedlings at 3.5 years.
- Observation The second fire produced 287 P. mollis subsp. nectens seedlings at 3.5 years.
- Intervention effect Significantly fewer seedlings followed the second fire.
- Observation Seedlings clustered significantly at small scales around dead adults.
- Intervention effect The second fire tightened clustering around dead adults.
- Intervention effect The second fire yielded fewer seedlings dispersed away from adults.
- Observation Population growth rates of all five Persoonia species were not significantly different from 1 in the normal year.
- Association Population growth rates trended downward in all species and sites in the drought year.
- Association The drought-year population growth reduction was significant in P. glaucescens.
- Association The drought-year population growth reduction was significant in P. bargoensis.
- Association Seed-bank survival became most influential for rare P. glaucescens and P. bargoensis during drought.
- Association Rare Persoonia species buffered drought less effectively through survival than common species.
- Observation Modeled regular fire return intervals shorter than 8–10 years led to extinction of all Persoonia populations.
