Non-indigenous (NIS) and cryptogenic species in European regional seas and adjacent areas

The dataset includes 3305 georeferenced points/records. The data records were gathered using three types: digitalization, exact occurrences, and expert judgment.

The georeferenced data was extracted from the scientific publications and specialized databases (AquaNIS, ICES, and Google scholar). Main aim to make this database of non-native species to count invasiveness using quantitative criteria MER (Sandvik et al. 2013) to predict the spread between different alien species (Srėbaliene. PhD thesis. 2019).
