There are nearly 2,000 invasive non-native species (INNS) established in GB; the majority being terrestrial (c. 1,800) as well as those established in marine and freshwater environments (c.160). The number of INNS establishing themselves in GB is around 10-12 annually. Well-known animal INNS include American mink, signal crayfish and the grey squirrel, alongside plant species such as Japanese Knotweed.

Costs and environmental impacts associated with invasive species have been increasing dramatically in recent years. The annual cost to the GB economy is at least £1.7 billion; with Japanese Knotweed alone estimated to account for £166 million of that total. Associated with the economic impact there is the potential for significant disruption to habitats and ecosystems; coupled with social impacts in terms of human health and nuisance.

This webinar will give an overview of relevant legislation and will discuss recent updates and approaches to invasive species risk assessment and management supported by case studies.
