The importance of managing invasive non-native species (INNS), be it through eradication or limitation, is set out in the United Nations Convention on Biological Diversity (CBD) which states that parties to the Convention should ‘prevent, control or eradicate alien species’ (IUCN, 2000). Unfortunately there is some evidence that botanic gardens have been implicated in being responsible for the early introduction of many environmental weeds listed by IUCN as among the worst invasive species (Hulme, 2011). Stronger global networking between botanic gardens to tackle the problem of INNS has been suggested by Hulme. Botanic gardens have a remit to meet Target 10 of the Global Strategy for Plant Conservation (GSPC) and the European Strategy for Plant Conservation (ESPC) Targets 10.1 and 10.2. The National Botanic Gardens, Glasnevin, in conjunction with University College Dublin and Mayo and Fingal County Councils, with grant funding from the Heritage Council, has monitored populations then researched and implemented effective control methods of two escaped garden plants: Hottentot fig (Carpobrotus edulis (L.) N.E. Br.) and giant rhubarb (Gunnera tinctoria (Molina) Mirb.) in EU protected habitats and in Special Areas of Conservation (SACs) in Ireland. Chemical treatments were trialled and tested in the field for both species, and successful regeneration of native vegetation in formerly invaded areas has been observed since treatments began in 2009.References
