         Management Information

Preventative measures: A Risk Assessment of Buddleja davidii 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 13 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."
Biological: Researchers in New Zealand are currently studying the possibility of biological control with the coleopter Cleopus japonicus.
Integrated management: Management methods such as digging it out are applicable only to minor infestations at the initial stage of invasion. Cutting inflorescences before they bear fruit is a preventative technique, which makes it possible to limit the production of the seeds. Disturbances caused by uprooting young Buddleia shrubs actually assist its development. After uprooting, planting alternative species is recommended. It is necessary to remove uprooted plants which can grow as cuttings. When it is cut, Buddleia grows back from the stump very vigorously. Cutting must be carried out at the base of the seedling and be accompanied by an immediate white-washing of the stump with a systemic weedkiller.

         Location Specific Management Information
Ascension Is.
Buddleja davidii was partially cleared from the mountain around 1900 (Ashmole and Ashmole, 2000 in Varnham, 2006).
Isle of Man
Very localised removal from one diverse limestone quarry has been attempted (Charter, 2004 in Varnham, 2006).
Languedoc-Roussillon
Local treatment in a riparian zone
New Zealand
Researchers in New Zealand are currently studying the possibility of biological control with the coleopter Cleopus japonicus (Brunel, S., pers.comm. 2004).

        Summary: The database of alien plants in Ireland contains detailed information on 715 alien plant taxa currently occurring in (semi-) natural habitats in Ireland (both the Republic and Northern-Ireland). This database was developed in 2006 at the School of Natural Sciences, Trinity College Dublin, as part of the BioChange project, funded by the Environmental Protection Agency (EPA), Ireland.

This version of the database has been developed by the IUCN SSC ISSG as part of an Overseas Territories Environmental Programme funded project XOT603 in partnership with the Cayman Islands Government - Department of Environment. The compilation is a work under progress, the ISSG will manage, maintain and enhance the database with current and newly published information, reports, journal articles etc.
