Family: Fabaceae
High Risk Traits:
- Naturalized beyond native range (Puerto Rico, Cuba, Trinidad, Christmas Island)
- Broad climate versatility (0–1300 m elevation; tropical/subtropical)
- Repeated introductions outside native range
- Host for pests/pathogens (e.g., stem borer Aristobia horridula)
- Nitrogen-fixing (alters soil nutrients)
- Self-compatible (can set seed from single tree)
- Propagules dispersed intentionally (planted ornamentally/for forestry)
- Wind-dispersed (winged pods)
- Water-dispersed (pods float)
- Tolerates mutilation, fire, coppicing (regrows after logging or fire)
Low Risk Traits:
- No congeneric weeds
- No spines, thorns, or burrs
- No allelopathy or parasitism
- Not toxic to animals or humans
- Requires specialist pollinators (large bees)
- No vegetative spread in wild
- Long minimum generative time (~4+ years)
- No unintentional dispersal (no attachment structures)
- Not bird-dispersed; no gut survival
- Low seed production (few seeds per pod)
