Aligning with the International Day for Biological Diversity's theme of "Acting locally for global impact," researchers have released a comprehensive blueprint for building a robust, globally adaptable network of DNA barcoding practitioners.

DNA barcoding has become a cornerstone for modern species identification and biodiversity monitoring, proving vital for applications ranging from ecological research to conservation and environmental policy. Since its inception, the DNA barcoding community worldwide has been convening under the aegis of the International Barcode of Life (iBOL), which provides necessary global coordination. To implement barcoding at scale, build local capacity, and translate scientific advances into actionable practice, iBOL national nodes have been established since the 2010s

Published in the open-access journal Metabarcoding and Metagenomics, the article "Empowering national capacity for a DNA-based approach to species identification and biodiversity monitoring" by E. Kaitetzidou et al. provides strategic advice on establishing iBOL national nodes.

Drawing on a survey and workshop conducted under the Horizon Europe Biodiversity Genomics Europe project, this research synthesises experiences from 20 countries, including 17 in Europe, and examines how national nodes are initiated, governed, and sustained. Common challenges include defining scope, securing sustainable funding, harmonising methodologies, and engaging stakeholders. For example, a particularly striking finding was how rarely node coordinators sought guidance from established networks before setting up their own.

"The decision-making process and steps taken were almost entirely based on intuition and the experience from other within-country activities, as well as their perceptions of the activities of other nations' barcoding nodes,"

- the researchers note.

Central to the paper are ten practical recommendations to ensure the establishment and long-term success of national DNA barcoding nodes. The authors emphasise several key priorities, primarily the construction of comprehensive DNA barcode reference libraries and the critical need to align scientific activities with practical biomonitoring requirements. Furthermore, they strongly advocate for promoting FAIR (Findable, Accessible, Interoperable, and Reusable) and CARE data principles, alongside implementing focused strategies for capacity building, methodological standardisation, communication, and diverse stakeholder engagement.

Stronger national infrastructures will enhance Europe's capacity for DNA-based biodiversity monitoring and support metabarcoding and metagenomic research. Building on milestones such as the establishment of iBOL Europe in 2022, these local efforts add up to real progress on species discovery, conservation, and environmental management worldwide.
