In Ireland, practical management of introduced species is challenging because of the cross-border implications of controlling introductions and spread. A pro-active stance is fundamental since prevention of introductions is demonstrably more cost-effective than reactive control or eradication measures.

In March 2004, the "Invasive Species in Ireland" report was presented to both Ministers and it was agreed that Environment and Heritage Service in Northern Ireland and the National Parks and Wildlife Service in the Republic of Ireland would work together and with others to tackle the invasive species problem. In response to the recommendations of this report the ‘Invasive Species in Ireland’ project started in May 2006. This joint EHS/NPWS contract is being undertaken by a partnership of EnviroCentre and Quercus.
