Impact

Impact: Information on the impact of introduced and invasive marine species has been recorded. These include impacts on native species, their habitats and ecosystems, human health and activity, transmission of diseases, etc. Descriptive terms of impacts were standardized and listed in a look-up table. These terms have been adapted from Hayes (2005).
