Two ambitious multi-stakeholder projects that aim to tackle the threat of invasive alien species have been launched at a conference in Europe this week (20-23 January 2025).

GuardIAS and OneSТOP — covering marine and freshwater, and terrestrial habitats respectively — will work in tandem to alleviate the adverse impacts of invasive alien species on endangered species, natural sites and human health, providing comprehensive coverage of Europe’s ecosystems.

Invasive alien species — animals and plants that are introduced accidentally or deliberately into a natural environment where they are not normally found — are major threats worldwide, contributing to 60% of plant and animal extinctions and costing over $400 billion annually to global economies. The challenges associated with invasive alien species are likely to intensify with climate change and ongoing globalisation.

The GuardIAS and OneSTOP projects will use advanced scientific research, cutting-edge technology, and artificial intelligence to develop new tools and methods that will prevent, detect, prioritise, eradicate, and manage invasive alien species — covering all steps of the biological invasion process.

In addition, a significant aspect of both projects is public engagement and wider community involvement, including Citizen Science initiatives, outreach and art events, and the development of interactive games to gain support and promote action in addressing the threats of invasive alien species.

“We have created a multi-disciplinary approach, which I am very excited about”, said GuardIAS Project Coordinator Professor Stelios Katsanevakis, University of the Aegean, Greece. “We have brought together public research institutes, universities, non-profit associations, small/medium enterprises and the EU’s Joint Research Centre to work on the issue. Through this, we will create a far-reaching outreach programme that involves the wider community in addressing the challenges posed to society by invasive alien species.”

Prof Katsanevakis continued, “The GuardIAS project aims to improve the detection and prevent the spread of invasive alien species in both marine and freshwater habitats using a range of novel methods — such as artificial intelligence (AI), environmental DNA, satellite imagery, underwater robotics and monitoring systems, and the development of an early alert system. Information gained from the research will be used to increase public awareness regarding threats from invasive species spread, enhance public engagement, and enable decision makers to prioritise where and when to act.”

GuardIAS and OneSTOP will develop solutions for the management of invasive alien species at multiple governance levels, from local to international — and will also conduct analyses to assess invasion risks under various future scenarios, including climate change.

“It has been an incredible week at the Joint Research Centre in Ispra, hearing the scope of both projects and being with the different partners and stakeholders, discussing and collaborating, said Professor Helen E. Roy from the UK Centre for Ecology & Hydrology and University of Exeter, who is co-leading OneSTOP. “We have been aware for many years that there are datasets in many different places, with different people doing different things in different ways, and we knew there had to be a way to bring it all together. And now, we are launching initiatives to build on the incredible progress of the last decade. It is an exciting and significant moment for all involved”.

OneSTOP’s coordinator Doctor Quentin Groom from Meise Botanic Garden, Belgium, shared the reasoning behind the project, “To comprehensively address the issue of invasive alien species, OneSTOP is working around four main objectives. We are developing new tools allowing us to detect invasive alien species better. We are connecting these tools to systems which send information to the interested stakeholders faster. Based on the obtained data, we are also developing a system which allows policymakers to prioritise action on invasive alien species. Throughout all of this, we are working closely with people on a regional level through Living Labs and on an international level with a policy forum.”

A key part of both projects are work packages that will use Artificial Intelligence (AI) to systematically query different biodiversity databases for information about invasive alien species — for example, species distribution, environmental tolerances, biological traits, and genetic information, streamlining multiple datasets.

To complement the EU efforts for an official reporting system and the European Alien Species Information Network (EASIN), the projects will be co-developing an Alert System on invasive alien species.

Funded by Horizon Europe, the projects have been hailed as not just a response to current environmental challenges but also a proactive step towards sustainable management and conservation of aquatic and terrestrial ecosystems in Europe. The comprehensive approach of the projects, encompassing science, technology, and community engagement, positions them as key players in the EU's efforts to preserve biodiversity and protect ecosystems from the growing threat of invasive species in alignment with the EU Biodiversity Strategy for 2030 and the Invasive Alien Species (IAS) Regulation.
