Understanding uncertainty in the Impact Classification for Alien Taxa (ICAT) assessments

Probert, Anna F. ; Volery, Lara ; Kumschick, Sabrina ; Vimercati, Giovanni ; Bacher, Sven

In: NeoBiota, 2020, vol. 62, p. 387–405

The Environmental Impact Classification for Alien Taxa (EICAT) and the Socio- Economic Impact Classification of Alien Taxa (SEICAT) have been proposed to provide unified methods for classifying alien species according to their magnitude of impacts. EICAT and SEICAT (herein “ICAT” when refered together) were designed to facilitate the comparison between taxa and invasion contexts by using a...

Improving the Environmental Impact Classification for Alien Taxa (EICAT): a summary of revisions to the framework and guidelines

Volery, Lara ; Blackburn, Tim M. ; Bertolino, Sandro ; Evans, Thomas ; Genovesi, Piero ; Kumschick, Sabrina ; Roy, Helen E. ; Smith, Kevin G. ; Bacher, Sven

In: NeoBiota, 2020, vol. 62, p. 547–567

The Environmental Impact Classification for Alien Taxa (EICAT) classifies the impacts caused by alien species in their introduced range in standardised terms across taxa and recipient environments. Impacts are classified into one of five levels of severity, from Minimal Concern to Massive, via one of 12 impact mechanisms. Here, we explain revisions based on an IUCN-wide consultation process...

The importance of assessing positive and beneficial impacts of alien species

Vimercati, Giovanni ; Kumschick, Sabrina ; Probert, Anna F. ; Volery, Lara ; Bacher, Sven

In: NeoBiota, 2020, vol. 62, p. 525–545

Extensive literature is available on the diversity and magnitude of impacts that alien species cause on recipient systems. Alien species may decrease or increase attributes of ecosystems (e.g. total biomass or species diversity), thus causing negative and positive environmental impacts. Alien species may also negatively or positively impact attributes linked to local human communities (e.g....

Frameworks used in invasion science: progress and prospects

Wilson, John R.U. ; Bacher, Sven ; Daehler, Curtis C. ; Groom, Quentin J. ; Kumschick, Sabrina ; Lockwood, Julie L. ; Robinson, Tamara B. ; Zengeya, Tsungai A. ; Richardson, David M.

In: NeoBiota, 2020, vol. 62, p. 1–30

Our understanding and management of biological invasions relies on our ability to classify and conceptualise the phenomenon. This need has stimulated the development of a plethora of frameworks, ranging in nature from conceptual to applied. However, most of these frameworks have not been widely tested and their general applicability is unknown. In order to critically evaluate frameworks in...

Appropriate uses of EICAT protocol, data and classifications

Kumschick, Sabrina ; Bacher, Sven ; Bertolino, Sandro ; Blackburn, Tim M. ; Evans, Thomas ; Roy, Helen E. ; Smith, Kevin

In: NeoBiota, 2020, vol. 62, p. 193–212

The Environmental Impact Classification for Alien Taxa (EICAT) can be used to classify alien taxa according to the magnitude and type of their environmental impacts. The EICAT protocol, classifications of alien taxa using the protocol (EICAT classification) and the data underpinning classifications (EICAT data) are increasingly used by scientists and practitioners such as governments, NGOs...

More than “100 worst” alien species in Europe

Nentwig, Wolfgang ; Bacher, Sven ; Kumschick, Sabrina ; Pyšek, Petr ; Vilà, Montserrat

In: Biological Invasions, 2018, vol. 20, no. 6, p. 1611–1621

“One hundred worst” lists of alien species of the greatest concern proved useful for raising awareness of the risks and impacts of biological invasions amongst the general public, politicians and stakeholders. All lists so far have been based on expert opinion and primarily aimed at representativeness of the taxonomic and habitat diversity rather than at quantifying the harm the alien...

A vision for global monitoring of biological invasions

Pyšek, Petr ; Jeschke, Jonathan M. ; Blackburn, Tim M. ; Bacher, Sven ; Capinha, César ; Costello, Mark J. ; Fernández, Miguel ; Gregory, Richard D. ; Hobern, Donald ; Hui, Cang ; Jetz, Walter ; Kumschick, Sabrina ; McGrannachan, Chris ; Pergl, Jan ; Roy, Helen E. ; Scalera, Riccardo ; Squires, Zoe E. ; R.U.Wilson, John ; Winter, Marten ; Genovesi, Piero ; McGeoch, Melodie A.

In: Biological Conservation, 2017, vol. 213, no. Part B, p. 295–308

Managing biological invasions relies on good global coverage of species distributions. Accurate information on alien species distributions, obtained from international policy and cross-border co-operation, is required to evaluate trans-boundary and trading partnership risks. However, a standardized approach for systematically monitoring alien species and tracking biological invasions is still...

Socio-economic impact classification of alien taxa (SEICAT)

Bacher, Sven ; Blackburn, Tim M. ; Essl, Franz ; Genovesi, Piero ; Heikkilä, Jaakko ; Jeschke, Jonathan M. ; Jones, Glyn ; Keller, Reuben ; Kenis, Marc ; Kueffer, Christoph ; Martinou, Angeliki F. ; Nentwig, Wolfgang ; Pergl, Jan ; Pyšek, Petr ; Rabitsch, Wolfgang ; Richardson, David M. ; Roy, Helen E. ; Saul, Wolf-Christian ; Scalera, Riccardo ; Vilà, Montserrat ; Wilson, John R. U. ; Kumschick, Sabrina

In: Methods in Ecology and Evolution, 2017, p. -

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...
