Family: Fabaceae
High Risk Traits:
- Elevation range exceeds 2000 m in tropical latitudes, demonstrating environmental versatility
- Thrives in tropical climates
- Reportedly naturalized (or persisting from cultivation) in Brazil, New Zealand and possibly elsewhere (but no evidence in the Hawaiian Islands to date)
- Possibly allelopathic
- Raw seeds may be toxic
- Tolerates many soil types
- Climbing and potentially smothering growth habit
- Tuberous roots (may allow plants to persist and regrow after damage or removal of above-ground vegetation)
- Reproduces by seeds
- Self-fertile
- Perennial, but able to reach maturity in <1 growing season
- Seeds dispersed by people
- Seeds hard coated and able to be stored for several years; likely to form a persistent seed bank
Low Risk Traits:
- A domesticated plant known only from cultivation
- No evidence of negative impacts due to cultivation
- Unarmed (no spines, thorns, or burrs)
- Provides fodder for livestock
- Require full sunlight (could limit ability to spread into intact forests)
- Edible to humans
- Not reported to spread vegetatively
- Relatively large pods and seeds unlikely to be inadvertently dispersed
