Summary of responses from experts that assessed lists of alien species for different countries

See McGeoch et al. 2012 Ecol Applications. Experts were sent lists of aliens (for different taxa in different countries) and asked to assess the lists for whether they agreed, did not agree or did not know whether the species should be listed as alien for that country. Experts were also asked to add species to lists. The lists assessed were those compiled for the global invasive alien species indicator database.
