The workflow integrates three complementary data sources to classify each occurrence as native, non-native, contradictory, or unknown. It's output provides a harmonised dataset as base for further analyses, facilitating comparative studies on topics such as the distribution and establishment potential of non-native species, or regional characteristics of their non-native ecological niches. The workflow was conceptualised and implemented by Anna Rönnfeldt, Katrin Schifferle, Valén Holle, and Damaris Zurell. Related publications Holle et al.

It lists 3963 vascular plant species known to occur as naturalised species on the Pacific Islands spatial data corresponding to level 3 tdwg regions GloNAF data for the status assignment Workflow A detailed workflow description is provided in the README of the GitHub repository.
