Other claims from this paper (18)
- Observation Four of five woody species are projected to decline under frequent burning.
- Observation The same four woody species are projected to increase under infrequent burning.
- Observation Fire intervals of 2–9 years are required for long-term persistence of those four species.
- Observation The fifth shrub species was nearly unaffected by burning.
- Association Population growth under annual burning was negatively associated with growth under unburned conditions.
- Observation Woody plants performed best at low fire frequency.
- Observation Herbaceous plants performed best at high fire frequency.
- Intervention effect Fire stimulated vegetative propagation in three species.
- Intervention effect Fire reduced sexual reproduction in those three species.
- Observation Vegetative propagation was relatively more important with frequent burning.
- Observation Stasis and progression contributed more to population growth than either reproductive mode.
- Observation Fire effects on sexual reproduction contributed little to overall population growth effects.
- Observation Fire mortality had little population growth effect except in Miconia albicans.
- Observation Fire reduction of individual size made the greatest contribution to negative population growth.
- Observation Size effects were greater for trees than shrubs.
- Association Growth form was the primary determinant of fire response.
- Observation Current fire regimes are projected to reduce woody plant density.
- Observation Current fire regimes are projected to favor smaller life forms and clonal species.
