- Intervention effect Survival, fecundity and growth responded only slightly to density manipulation.
- Association Small plants were favoured in several respects by crowding.
- Mechanism The weak neighbour responses suggest that mature Salvia populations are not strongly self regulating at normal density or effects take over two years to appear.
- Mechanism Seedling mortality and density independent growth determinants appear to keep the adult population below the density where neighbour effects are strong.
