Biological invasions by non-native species are currently one of the biggest threats to the ecology and economy of the planet, costing an estimated £914 billion* worldwide and being the cause of 50% of all known extinctions.

Invasive species can act as vectors for new diseases, alter ecosystem processes, change biodiversity, disrupt cultural landscapes, reduce the value of land and water for human activities and cause other socio-economic consequences. Our changing climate may force us to rethink some of our strategies for the control and accept some species as new natives in our UK biodiversity.

Conference speakers will talk about the European picture; examine the recent changes to the Wildlife and Countryside Act (1981), as well as looking at the UK national non-native strategy.

Practical case studies for both terrestrial and aquatic species will be explored throughout the day. Examples will include research on the biological control of Japanese Knotweed using Aphalara itadori, the implications of the Killer Shrimp Dikerogammarus villosus and the impacts of pathogens such as Phytophthora ramorum on plants and trees.
