Other claims from this paper (6)
- Observation Achillea millefolium produced more than four times the biomass of Poa fawcettiae.
- Intervention effect High density reduced both root and shoot biomass per A. millefolium plant in monoculture.
- Intervention effect P. fawcettiae biomass was unaffected by density.
- Intervention effect P. fawcettiae did not affect A. millefolium biomass in mixed pots.
- Intervention effect A. millefolium reduced P. fawcettiae shoot and root biomass at all tested densities.
- Observation A. millefolium may have a competitive advantage in the Australian Alps.
