Family: Myrtaceae

Origin, Description & Uses:
Eucalyptus urograndis is a fast-growing hybrid developed from Eucalyptus urophylla and Eucalyptus grandis, both native to regions of Southeast Asia and Australia. This hybrid is widely cultivated in tropical and subtropical areas due to its adaptability, rapid growth, and straight trunk form. Typically reaching medium to tall heights, it has smooth bark that sheds in patches and elongated, aromatic leaves characteristic of eucalyptus species. It is commonly planted for commercial forestry, especially for pulpwood, timber, and biomass production, and is also used in windbreaks and reforestation projects.

Risks & Threats:
This hybrid is generally considered low risk, as it is typically managed in plantation settings and does not commonly spread aggressively on its own. However, like other eucalyptus species, it may pose some localized concerns if planted near natural areas, including competition with native vegetation, high water use, and the potential to alter fire behavior due to its flammable oils and leaf litter. While Eucalyptus urograndis has not been widely reported as invasive, continued monitoring is recommended to ensure it does not establish beyond intended plantings or impact surrounding ecosystems.

High Risk Traits:

• Grows in tropical and subtropical climates
  
• Broad climate suitability
  
• Other Eucalyptus species documented to be invasive
  
• Allelopathic properties
  
• Unpalatable to browsing animals
  
• Host of Puccinia spp. and other pathogens
  
• Seeds may be wind-dispersed (if produced)
  
• Able to coppice

Low Risk Traits:

• No reports of naturalization or weediness despite widespread cultivation
  
• Unarmed
  
• Non-toxic
  
• Shade-intolerant
  
• Limited or no seed set
  
• Self-incompatible
  
• Biomass tree for pulp, paper, and fuel
  
• Herbicides may provide effective control if trees do spread
