Family: Anacardiaceae

Origin, Description & Uses
Rhus taitensis is a small tree or large shrub native to a broad region extending from eastern Java through much of the Pacific Islands. It typically grows in coastal and lowland environments and is recognized by its divided leaves, clusters of small flowers, and reddish fruiting structures. In parts of its native range, it has been used locally for shade and ornamental planting, and some traditional uses have included wood and plant materials for small-scale utilitarian purposes.

Risks & Threats
In Hawaiʻi, Rhus taitensis is considered naturalized on Oʻahu and is potentially continuing to establish in the wild. This species possesses traits that are cause for concern in tropical island ecosystems, including its ability to spread beyond plantings and persist in disturbed habitats, where it may compete with native vegetation. As it expands, it could contribute to the displacement of native species and further alter ecosystem structure and function. Choosing low-risk or native alternatives is recommended when available. Where this species is already present, efforts should focus on preventing further planting and limiting its spread into areas where it is not yet widely established to reduce additional ecological impacts.

High Risk Traits:

• Naturalized outside native range (O'ahu)
  
• Congeneric weed (Rhus typhina is invasive)
  
• Tolerates wide range of soil conditions
  
• Produces viable seed
  
• Bird-dispersed seeds
  
• Seeds survive gut passage
  
• Prolific seed production (>1000/m²)
  
• Resprouts after fire or mutilation

Low Risk Traits:

• Not a weed of gardens, agriculture, or forestry
  
• No spines, thorns, or burrs
  
• Not toxic to animals or humans
  
• No wind or external animal dispersal
