Invasive alien species threaten urban environments

Europe's towns and cities are particularly vulnerable to the threat posed by invasive species, say experts.

They say urban areas are at higher risk from invasive alien species (IAS) as a result of more transport links.

IAS are non-native plants or animals that have no natural predators, spread rapidly and overwhelm an area's native flora and fauna.

Next week, the European Commission is expected to outline its plans to tackle the continent's invasive species.

"These non-indigenous species represent one of the main threats to the world's biodiversity," explained Chantal van Ham, European program officer for the International Union for Conservation of Nature (IUCN).
