Other claims from this paper (8)
- Intervention effect Amsinckia menziesii reduced E. macrophyllum seed production.
- Intervention effect Erodium brachycarpum reduced E. macrophyllum seed production.
- Intervention effect Bromus spp. reduced E. macrophyllum seed production.
- Observation The three competitors seldom affected E. macrophyllum seedling establishment.
- Observation A. menziesii had the most negative effect on E. macrophyllum or an effect equivalent to E. brachycarpum, while Bromus spp. had the least negative effect.
- Observation Bromus had the lowest density and recolonization rate among the three matrix species.
- Observation Soil under Bromus had the highest extractable N and P levels.
- Recommendation The authors recommend weeding known competitors to increase E. macrophyllum seed production and restoration prospects.
