Digital biodiversity data has come a long way. Twenty-five years ago, the Global Biodiversity Information Facility (GBIF) launched with 21 founding countries and a simple but ambitious goal: make the world's biodiversity data freely and openly available to anyone, anywhere. Today, GBIF’s network includes 70 participating countries, along with data providers across more than 120 countries, offering open access to over 3.8 billion biodiversity data records. This milestone is explored in a new overview article published in the Biodiversity Data Journal, which traces GBIF's trajectory over the past quarter-century and the challenges that remain as it looks ahead.

GBIF Executive Secretary Dr. Joe Miller remarked:

As GBIF celebrates its 25th anniversary, I’m very proud to serve as Executive Secretary of the organisation and to have contributed to this milestone publication. Detailing the history of GBIF both as an infrastructure and a global network, the article pays tribute to all the people involved in the network throughout a quarter century—be they staff, participants, nodes, volunteers, data publishers or data users. It represents the past, present and future of GBIF. I believe the paper will help strengthen our network and its capacity to respond to biodiversity data needs both now and in the future.

GBIF was established in 2001, following a proposal from the Organisation for Economic Cooperation and Development’s Megascience Forum which concluded that “an international mechanism is needed to make biodiversity data and information accessible worldwide”. The call came in response to a problem facing the international community after the 1992 Rio Earth Summit: the world's biodiversity knowledge was scattered across a small number of institutions, concentrated in wealthy countries, with no shared way to bring it together in support of the newly signed Convention on Biological Diversity.

Now, a quarter-century later, GBIF has become the foundational infrastructure for biodiversity science and policy worldwide.

A Growing Global Network

GBIF's work is carried out through a distributed network of 47 voting country participants and 42 organisational participants, each represented by a national or thematic "node" that mobilises data, builds local capacity, and connects biodiversity communities to GBIF's infrastructure. 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, totalling nearly 3500 organisations involved.

Data Supporting Science and Policy

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, spanning fields from climate change and food security to public health and invasive species management. An independent 2023 assessment estimated that GBIF generates roughly €12 in societal benefit for every €1 invested, with researcher time savings alone valued at €35 million annually.

The organisation's impact also extends deeply into international policy. GBIF-mediated data support multiple indicators under the Kunming-Montreal Global Biodiversity Framework, inform assessments by the International Union for Conservation of Nature (IUCN) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), and are increasingly used by the private sector to meet emerging nature-related disclosure requirements.

Adapting to New Kinds of Data

Over 25 years, GBIF has continually expanded to accommodate new sources of biodiversity data - from digitised natural history specimens and citizen science observations to DNA-based records and, most recently, structured survey and monitoring data designed to support large-scale biodiversity tracking. 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.

Persistent Gaps Remain

Despite this growth, GBIF recognises that several significant challenges remain. The global loss of biodiversity continues to be described as a crisis in major international assessments, even as the data infrastructure has improved. And the data itself continues to reflect long-standing imbalances - regions with high biodiversity, particularly in the Global South, remain underrepresented, while well-studied, charismatic groups such as birds are overrepresented compared to less visible taxa; furthermore, many marine species and hard-to-identify cryptic habitats and organisms remain inadequately documented.

Closing these gaps was part of the original motivation for creating GBIF a quarter-century ago, and it remains valid today. GBIF'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.

An additional, ongoing challenge is data heterogeneity and data 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 – a distributed model that keeps the network scalable but is not without friction.

Looking Ahead

Guided by its 2023–2027 Strategic Framework, GBIF is prioritising continued growth of its Participant network, expanded support for survey and monitoring data, and deeper integration of DNA-derived biodiversity records – all aimed at closing longstanding geographic and taxonomic gaps in digital biodiversity data worldwide.
