Twenty-Five Years of Open Biodiversity Data: How GBIF Grew to 3.8 Billion Records

Twenty-five years ago, the idea that anyone with an internet connection could freely access billions of records describing where the world’s species live would have sounded like science fiction. Today it is an everyday reality for scientists, policymakers and citizen scientists alike. The Global Biodiversity Information Facility, known as GBIF, launched in 2001 with 21 founding countries and a deceptively simple ambition: to make the planet’s biodiversity data freely and openly available to anyone, anywhere. A quarter of a century later, the network spans 70 participating countries and 42 associate participants, with data providers active across more than 120 countries, and its index now exceeds 3.8 billion biodiversity records. A new overview published in the Biodiversity Data Journal traces this remarkable trajectory and takes an honest look at the work that still lies ahead.

The origins of GBIF lie in a diagnosis made by the international scientific community in the years following the 1992 Rio Earth Summit. The newly signed Convention on Biological Diversity created an urgent demand for reliable information about the distribution and status of the world’s species, but the knowledge needed to meet that demand was scattered across a small number of institutions, concentrated overwhelmingly in wealthy countries, with no shared mechanism to bring it together. The Organisation for Economic Cooperation and Development’s Megascience Forum concluded that an international mechanism was needed to make biodiversity data and information accessible worldwide. That conclusion led directly to the establishment of GBIF in 2001, an infrastructure designed from the outset around the principles that would later be formalised as FAIR: data that are findable, accessible, interoperable and reusable.

What began as an effort to digitise the contents of natural history museums has evolved into something far broader. Over 25 years, GBIF has continually expanded to accommodate new kinds of biodiversity information, from digitised natural history specimens and citizen science observations to DNA-based records derived from molecular work. Most recently, the infrastructure has grown to handle structured survey and monitoring data designed to support large-scale biodiversity tracking, allowing researchers to move beyond simple presence records toward understanding population trends over time. In 2026, GBIF adopted the Catalogue of Life as its taxonomic backbone, the result of a multi-year collaboration to build shared infrastructure for reconciling species names across datasets. This taxonomic backbone is technically critical, because the same species can carry many names and the same name can refer to different species; reconciling these labels is what makes billions of heterogeneous records searchable and comparable.

The architecture underpinning this achievement is deliberately distributed. GBIF’s work is carried out through a network of voting country participants and organisational participants, each represented by a national or thematic node that mobilises data, builds local capacity and connects regional biodiversity communities to the global infrastructure. Rather than collecting data into a single central repository, GBIF indexes data that publishers maintain at source. More than 2,700 institutions, including museums, universities, government agencies, citizen science platforms and a growing number of private-sector organisations, have published data through the network, with new publishers joining at a rate of more than two every three days, bringing the total number of organisations involved to nearly 3,500. This model allows a comparatively small coordination office to steward an exponentially growing body of information contributed by thousands of independent institutions.

The scientific return on this investment is measurable and striking. GBIF-mediated data now underpin an average of eight new peer-reviewed research papers per day, and have contributed to more than 15,000 publications to date. The applications span an extraordinary range of fields: climate change research uses occurrence records to model how species ranges shift as temperatures rise; food security studies draw on crop wild relatives data; public health researchers map disease vectors; and invasive species managers track the spread of organisms beyond their native ranges. An independent 2023 assessment estimated that GBIF generates roughly 12 euros in societal benefit for every euro invested, with researcher time savings alone valued at 35 million euros annually. Few scientific infrastructures can document such a direct and quantifiable return on public investment.

The influence of GBIF data extends well beyond academic journals into the machinery of international environmental policy. GBIF-mediated data support multiple indicators under the Kunming-Montreal Global Biodiversity Framework, the landmark agreement through which the world’s nations have committed to halting and reversing biodiversity loss. The same records inform assessments by the International Union for Conservation of Nature and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, two of the most influential bodies in global conservation science. Increasingly, the private sector is also turning to GBIF-mediated data to meet emerging nature-related disclosure requirements, a development that signals how thoroughly open biodiversity data has penetrated from the museum basement into corporate boardrooms and regulatory frameworks.

Dr Joe Miller, GBIF’s Executive Secretary, reflected on the anniversary and the anniversary publication that documents it. He described pride in serving as Executive Secretary at this milestone and in contributing to the publication, which details the history of GBIF both as an infrastructure and a global network. In his view, the article pays tribute to everyone involved in the network across a quarter century, including staff, participants, nodes, volunteers, data publishers and data users, representing the past, present and future of the organisation. He expressed the hope that the paper will help strengthen the network and its capacity to respond to biodiversity data needs both now and in the future.

Yet the anniversary is also an occasion for candour about persistent shortcomings. The global loss of biodiversity continues to be described as a crisis in major international assessments, even as the data infrastructure has improved dramatically. The data themselves reflect long-standing imbalances in the practice of science. Regions with high biodiversity, particularly in the Global South, remain underrepresented, while well-studied, charismatic groups such as birds are heavily overrepresented compared with less visible taxa. Many marine species remain inadequately documented, as do hard-to-identify cryptic habitats and organisms. These are not merely technical problems; they mirror inequalities in scientific funding, institutional capacity and research priorities that have shaped the field for generations.

Closing these gaps was, in fact, part of the original motivation for creating GBIF a quarter-century ago, and the organisation’s own assessment is that the network cannot resolve these asymmetries alone. Doing so will depend on broader shifts in global scientific funding, data culture and capacity, alongside GBIF’s continued efforts to expand its participant network and to diversify the types of data it can mobilise. There is also an ongoing technical challenge of data heterogeneity and quality. Because GBIF indexes data rather than directly vetting every record, it relies on its network of data publishers to maintain quality at source and on users to report issues. This distributed model is what keeps the network scalable, allowing billions of records to flow into a single index, but it is not without friction, and users must remain alert to errors, misidentifications and gaps in even the most comprehensive datasets.

Looking toward its next 25 years, GBIF is guided by its 2023 to 2027 Strategic Framework, which prioritises continued growth of the participant network, expanded support for survey and monitoring data, and deeper integration of DNA-derived biodiversity records, all aimed at closing the longstanding geographic and taxonomic gaps in digital biodiversity data worldwide. The stakes of this work could hardly be higher. As nations race toward the targets of the Kunming-Montreal Global Biodiversity Framework, and as environmental change accelerates faster than traditional monitoring can follow, the ability to see life on Earth in near real time has become indispensable. From a proposal born of a post-Rio data crisis to an index of 3.8 billion records consulted dozens of times each day by working scientists, GBIF’s first quarter-century demonstrates what sustained, open, international cooperation can build. Its next chapter will determine whether the world can finally fill in the blanks on the map of life before they disappear.
