Family: Myrtaceae
High Risk Traits:
- Elevation range exceeds 1000 m, demonstrating environmental versatility
- Thrives in tropical climates
- Naturalized on Kauai, Oahu, Molokai, Maui, Lanai and probably Hawaii Island; also naturalized in Australia, South Africa, the continental US (Florida) and the West Indies
- An environmental weed in Australia and Florida, reported to form dense stands that reduce native biodiversity
- Host of fruit flies, as well as other fungal pathogens of Myrtaceae Tolerates many soil types (potential to spread not limited by substrate)
- May form thickets within native and introduced range
- Reproduces by seeds, and possibly by suckering
- Self-compatible
- Reaches maturity in as little as two years (although may take longer)
- Seeds dispersed by birds, pigs, other fruit eating animals and intentionally by people
- Tolerates repeated and severe pruning
Low Risk Traits:
- Naturalized in the Hawaiian Islands, but no reports to date of impacts to native ecosystems
- Unarmed (no spines, thorns, or burrs)
- Non-toxic
- Palatable to browsing animals and may provide fodder for livestock
- Edible fruit
- Thrives in full sun to partial shade (dense shade may limit spread)
- Seeds lose viability quickly and will not form a persistent seed bank
- Herbicides can provide effective control if needed
