The Non-native Species Secretariat has responsibility for helping to coordinate the approach to invasive non-native species in Great Britain. We are responsible to a Programme Board which represents the relevant governments and agencies of England, Scotland and Wales.
Invasive species upset the balance of the ecosystem
as they may be bigger, faster growing or more aggressive than the
native species. They may also have fewer natural predators to control
numbers. The native species are often unable to compete and fairly
quickly the invasive species take over.
