    預防措施一個針對夏威夷與其他太平洋島嶼的大葉金雞納樹(Cinchona pubescens)的風險評估,由 Kaulunani 都市森林計畫與美國森林服務部贊助,Dr. Curtis Daehler(UH Botany)執行。外來植物檢查系統衍生自 Pheloung et al。(1999)經過小幅修正使用在太平洋島嶼.(Daehler et al.2004)結果是 9 分,建議如下:可能在夏威夷與其他太平洋島嶼上引起重要的生態或者經濟的傷害,WRA 分數很高,以夏威夷和其他世界各地公開的生物學描述資訊為依據 。

    物理方法:人工方法,包括砍筏成株與拔除(挖)殘枝與幼苗,相當有效。這個方法有效的前提是,所有直徑大於 2 公分的根都被移除。移除樹苗是有效的,但是成熟的樹能從切割的殘枝重新萌芽。去除樹皮是無效的,即使去除樹皮向上到莖的 1 公尺:樹皮再生長,而且修理傷口,而且樹存活。

    化學方法 C. Pubescens對許多除草劑有抵抗性,因此化學控制需要使用合適的毒劑配方,例如 triclopyr , picloram, 2,4-D, metsulfuron methyl。合適的方法包括切割殘枝、基生樹皮與砍筏後噴藥。

    已經顯示出砍筏後噴藥在加拉巴哥島控制 C. Pubescens是有效的。2000 年控制試驗的評估顯示成功地殺死 C. Pubescens,使用picloram- metsulphuron 甲基除草劑噴到樹幹缺口。這種這組合方法,現在是加拉巴哥島國家公園例行的控制方法。(Buddenhagen et al.2004) English  français

            摘要: 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.

            摘要: This compilation of information sources can be sorted on keywords for example: Baits & Lures, Non Target Species, Eradication, Monitoring, Risk Assessment, Weeds, Herbicides etc. This compilation is at present in Excel format, this will be web-enabled as a searchable database shortly. 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.
