Invasive alien species: the urban dimension: case studies on strengthening local action in Europe

Invasive Alien Species (IAS) pose a significant threat to biodiversity in Europe, like elsewhere in the world. This threat is likely to increase in the future unless meaningful action is taken at all levels to control the introduction and establishment of these species and address those already introduced. It is estimated that the economic impact of IAS only in the European Union causes some 12.5 billion Euros worth of damage each year. Local and regional authorities have an important role to play in implementing international, EU and national biodiversity targets and can greatly contribute to raising awareness about IAS among decision-makers and citizens. With this publication, IUCN highlights the key role that European local authorities play in addressing the risks associated with biological invasions. IUCN aims to strengthen collaboration with all stakeholders in the urban environment and offers its scientific knowledge and expertise to support achieving the ambitious requirements of the future EU legislation.
