There is no sign of saturation in accumulation of alien species (AS) introductions worldwide, while the rate of spread for some AS seems to be increasing. Particular attention must be dedicated to Invasive Alien Species (IAS), i.e., AS that harm biodiversity and ecosystem services, or have a negative impact on the economy or human health. Managing biological invasions depends on accurate, detailed and up-to-date information on occurrences, distribution, pathways and impact of IAS at varying spatial scales across Europe and indeed globally. The challenges of gathering information on AS are recognized, but recent developments in citizen science, that is, the involvement of citizens in data collection or analysis for research projects, provide an opportunity to improve data flow and knowledge on AS. Further, it ensures effective and high quality societal engagement with the issue of IAS.
