This poster represents the “Study on Invasive Alien Species – Development of risk assessments to tackle priority species and enhance prevention” commissioned by DG_ENVIRONMENT as part of the European Commission.

AIM

Provide evidence base for:

• listing IAS of Union Concern

• allocation of conservation

resources

WHY? EU IAS Regulation

Template with predefined scoring ranges + confidence

Species distribution model (SDM)

Management annex

• Evidence on measures, their implementation

costs and effectiveness

• Possible methods to achieve prevention,

eradication, management

• Examples of managing methods in other areas
