Bidoiversity Genomics Europe plus (BGE+) builds on a pan-European collaboration to scale up the production and uptake of genomic evidence for taxonomy, monitoring and policy. It widens participation, standardises methods, and prepares a distributed European system for biodiversity genomics that links molecules to ecosystems. BGE+ has four objectives: (1) broaden participation and capacity; (2) make distributed genomic data production interoperable and FAIR by design; (3) translate evidence into practice through co-designed use-case roadmaps; and (4) define the service portfolio and assess financial and technical feasibility for a future European research infrastructure in biodiversity genomics. The consortium unites iBOL Europe (DNA barcoding), ERGA (reference genomes) and CETAF (taxonomic research and natural history collections) to align end-to-end workflows from field sampling to application. Through targeted cascade grants (Financial Support to Third Parties) and hands-on training, BGE+ enlarges community capacity while converging on shared protocols and standard practices, improving data interoperability and consolidating community efforts. Building on previous work, BGE+ carries forward the communities’ long-term vision: turning fragmented efforts into a coherent, scalable system that delivers reliable genomic evidence for taxonomy and policy.
