Interaction riskLow

- High
- Very high
- Why interaction risk is low
- Avoid trampling stems or collecting seed because the shrub supports recovering soils and specialist insects.
Responsible observation
- Notice: Compare fresh yellow flowers with older orange-red flowers along the same slender stem.
- Restore: Leave plants and leaf litter intact on burns and eroding slopes where roots stabilize soil.
