As is the case with much of biodiversity, population abundance and distribution data on invasive species is geographically and taxonomically patchy. However, unlike the rest of biodiversity there are differences in the priority associated with generating such data, as well as in the significance of particular species population variables, such as the knowledge of native range limits. There are therefore still a number of key research questions, but also informatics challenges and governance arrangements that need to be addressed to smooth the pipeline of knowledge from data to decision on biological invasions. Some of the solutions include efficient, repeated generation of new data on the presence and distribution of invasive species, capitalizing on the rapidly developing field of biodiversity informatics, and model-generated essential biodiversity variables for invasive species. The recent realization of the Global Register of Introduced and Invasive Species, for example, provides a significant step forward in connecting national scale invasive species occurrence information with decision makers, as well as a mechanism that is leveraging higher quality, more comprehensive, harmonized and more accessible information on invasive species.
