Family: Fabaceae
High Risk Traits:
- Broad climate suitability: Altitude range 0–2000 m; dry/moist tropics
- Widely introduced: Planted throughout tropics and subtropics
- Allelopathic: Suppresses understory vegetation
- Wide soil tolerance: Grows on alluvium, shale, limestone, and other types
- Nitrogen-fixing: Competitive advantage in poor soils
- Persistent seed bank: Seeds viable in soil for 2–3 years
- Tolerates mutilation: Withstands severe pruning
- Reproduces by seed: Produces abundant viable seed
Low Risk Traits:
- Not a significant weed: No evidence of being agricultural, environmental, or garden weed elsewhere
- Large seeds: Low seed production per m² (1600–3700 seeds/kg)
- Poor dispersal mechanisms: No adaptation for wind, water, animal attachment, or unintentional human dispersal
- Self-incompatible: Requires cross-pollination for seed set
- Shade-intolerant: Slow growth under shady conditions
- Palatable: Leaves and pods edible for livestock
- Fire-sensitive: Young plants susceptible to fire
- No congeneric weeds: Other Delonix species not problematic
