These data sheets are an adaptation of the IUCN supported Environmental Impacts Classification of Alien Taxa (EICAT) protocol for assessment of impacts of invasive species. A text version of the protocol is available in Hawkins et al. 2015 (see readme file). The data sheets provide a standard format for reporting and summarizing invasive species impacts.
