摘要：＜正＞Sri Lanka has been identified as one of the 34 biodiversity"hotpots"considering not only the high concentration of endemic species,but also the loss of over 75%of its primary vegetation.The country has recognized Invasive Alien Species（IAS） as a major threat to the native biodiversity and in 2009,14 species of alien fauna and 30 alien flora were identified as the national list of IAS in Sri Lanka based on their impact, invasiveness,extent of spread,and management priorities. Despite being a signatory to international and agreements related to trade（WTO, SAPTA,etc） and international conventions（CBD,IPPC,MARPOL）,the large number of ordinances/acts enacted to impose laws governing import of fauna and flora to the country have failed to sectoral nature of the enactments and institutional policies. Lack of risk assessment at the entry point and poor awareness and ignorance of the policy makers organizations responsible for imports,has made it extremely difficult to the regulatory authorities to prevent the entry of IAS to Sri Lanka.Exchange of germplasm between countries,macroeconomic policies introduced by the government in late 1970s,international aid such as entry of the Indian Peace Keeping Force to tackle terrorism in late 1980’s,and import liberalization after the Tsunami incident in 2004 that enabled import of living materials without proper regulations, enabled entry of many alien species that have already become invasive or potentially invasive to the ecosystems of the country.The paper highlights findings of a national project conducted by IAS experts in the country in 2008/2009 on entry and establishment of species through international trade,transport and aid,and presents the new IAS Management Act and the National Policy for IAS Management in Sri Lanka.
