Integrating biological and environmental data to solve key scientific and societal challenges

Biodiversity collections in the United States hold over a billion specimens and are essential to understanding the history of life on Earth, as well as patterns of biodiversity in response to environmental change. Each specimen is linked by metadata to an organism's name and the place and time of its collection. Extensive data have been collected on Earth's geology, hydrology, climate, and organisms—past and present—but the data remain largely fragmented. We report in the present article on community discussions to develop a roadmap and identify action items for the Building an Integrated, Open, Findable, Accessible, Interoperable, and Reusable (BIOFAIR) Data Network, directly linking the various types of biological and environmental data. The roadmap is organized into five themes: stocktaking and gap analysis, technological capacity building, best practices, education and training, and community building. Together, these themes chart a path from initial resource inventories and skill building to infrastructure development, cross‑disciplinary collaboration, and the establishment of FAIR‑compliant workflows and governance.
