Family: Poaceae
High Risk Traits:
- Broad climate suitability (temperate to tropical)
- Naturalized elsewhere
- A weedy, disturbance-adapted grass that impacts native biodiversity where invasive
- May also negatively impact pasture productivity
- Other Bothriochloa species are invasive
- Potentially allelopathic
- Host of crop pests and pathogens
- May increase fire risk where invasive
- Tolerates many soil types
- Can form monocultures, inhibiting growth or establishment of other species
- Reproduces by seeds and vegetatively by stolons or rhizomes
- Hybridizes with other species
- Apomictic
- Seeds disperse along roads, possibly by wind and water, and intentionally cultivated
- Prolific seed production
- Tolerates heavy grazing, mowing and fire
Low Risk Traits:
- Unarmed (no spines, thorns, or burrs)
- Valued as a palatable pasture species (grazed by cattle and sheep)
- Non-toxic
- Shade-intolerant (dense shade may inhibit spread)
- Not reported to form a persistent seed bank
- Herbicides may provide effective control
