Management Information Preventative measures: A Risk Assessment of Piper aduncum 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 18 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: Young plants can be uprooted by hand, although care must be taken to ensure that no pieces of rhizome are left behind in the soil (UF/IFAS, 2000). Chemical: Basal bark application of 20% Garlon 4, or cut stems at ground level and apply 50% Garlon 3A to the stump (UF/IFAS, 2000).          Management Resources/Links 1.

Conservation Biology Volume 18 Issue 2 Page 360.         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. 2.
