Many alien taxa are known to cause socio-economic impacts by affecting the different constituents of human well-being (security; material and non-material assets; health; social, spiritual and cultural relations; freedom of choice and action). Attempts to quantify socio-economic impacts in monetary terms are unlikely to provide a useful basis for evaluating and comparing impacts of alien taxa...

Addressing a critique of the TEASI framework for invasive species risk assessment

Leung, Brian ; Roura-Pascual, Nuria ; Bacher, Sven ; Heikkilä, Jaakko ; Brotons, Lluis ; Burgman, Mark A ; Dehnen-Schmutz, Katharina ; Essl, Franz ; Hulme, Philip E ; Richardson, David M ; Sol, Daniel ; Vilà, Montserrat

We address criticism that the Transport, Establishment, Abundance, Spread, Impact (TEASI) framework does not facilitate objective mapping of risk assessment methods nor defines best practice. We explain why TEASI is appropriate for mapping, despite inherent challenges, and how TEASI offers considerations for best practices, rather than suggesting one best practice.

TEASIng apart alien species risk assessments: a framework for best practices

Leung, Brian ; Roura-Pascual, Nuria ; Bacher, Sven ; Heikkilä, Jaakko ; Brotons, Lluis ; Burgman, Mark A. ; Dehnen-Schmutz, Katharina ; Essl, Franz ; Hulme, Philip E. ; Richardson, David M. ; Sol, Daniel ; Vilà, Montserrat

Some alien species cause substantial impacts, yet most are innocuous. Given limited resources, forecasting risks from alien species will help prioritise management. Given that risk assessment (RA) approaches vary widely, a synthesis is timely to highlight best practices. We reviewed quantitative and scoring RAs, integrating < 300 publications into arguably the most rigorous quantitative RA...
