    Preventative measures: A Risk Assessment of Cinnamomum camphora for Hawai‘i and other Pacific islands was prepared by Dr. Curtis Daehler (UH Botany) with funding from the Kaulunani Urban Forestry Program and US Forest Service. The alien plant screening system is derived from Pheloung et al. (1999) with minor modifications for use in Pacific islands (Daehler et al. 2004). The result is a score of 7.5 and a recommendation of: "Likely to cause significant ecological or economic harm in Hawai‘i and on other Pacific Islands as determined by a high WRA score, which is based on published sources describing species biology and behaviour in Hawai‘i and/or other parts of the world."

    Physical: According to Starr et al. (2003), small seedlings of C. camphora can be hand pulled or grubbed out. It is important that the roots are removed otherwise the tree could regrow.

    Chemical: Foliar spray with herbicides on young Cinnamomum camphora trees up to 3m tall is also effective. Basal bark or cut stump herbicide treatments are effective for trees up to 6m , or with a basal stem diameter up to 30cm with no multi stems. For basal bark, spray from ground level up to a height of 30cm or higher than where multi stems branch. français

            Summary: A study on the use of a screening system to assess proposed plant introductions to Hawaii or other Pacific Islands and to identify high-risk species used in horticulture and forestry which would greatly reduce future pest-plant problems and allow entry of most nonpests.
