WG3 Tasks

Task 1: Review studies on environmental and socio-economic impacts of IAS in Europe, and impact assessment methods for IAS available at global, European and National scales.

Task 2: Develop and propose pan-European standardised methods to measure the magnitude of actual and potential environmental and socio-economic IAS impacts in Europe, possibly based on species traits of IAS associated with these impacts and/or in an impact scoring system, to inform risk assessment and specifically EWRR.

Task 3: Assess actual and expected impact of priority IAS at European and National levels based on methods outlined in task 2; create mechanisms to accumulate, analyse and distribute knowledge on IAS impacts useful for researchers and practical for managers.
