One of the quiet giants of biodiversity science has formally shut its doors. Species 2000, the United Kingdom-registered organisation that spent 28 years building the most complete inventory of scientific names for life on Earth, officially ceased to exist on 5 May 2026, when the UK Companies House confirmed its full closure. The announcement, published as a short communication in the Biodiversity Data Journal, marks the end of a legal entity but emphatically not the end of its mission: all rights, responsibilities, data and infrastructure have been transferred to the Catalogue of Life Foundation, a not-for-profit organisation registered in the Netherlands since May 2022.
Species 2000 began in 1996 with an ambition that sounded almost audacious at the time: to assemble a vetted, unified list of species names covering every known organism on the planet. The idea was to create a federation of database organisations working closely with taxonomists, data users and sponsoring agencies, rather than a single monolithic database. The organisation itself was formally established on 11 December 1997 as a limited company by guarantee, registered with the UK Companies House, with the International Union of Biological Sciences acting as witness to its founding. For more than 28 years it operated continuously, an unusually long life for a small scientific coordination body.
The flagship activity of Species 2000 was the Catalogue of Life, a project designed to compile a peer-reviewed list of species names for all life on Earth and to serve that data to scientists, educators, government agencies, businesses and countless other users. Data flowed in from taxonomists, data scientists and government organisations around the world, each contributing expertly curated segments of the tree of life. In 2001, the Catalogue of Life was first published online through a partnership with the Integrated Taxonomic Information System, and in 2003 that partnership was formalised with a grant from the Global Biodiversity Information Facility that gave the endeavour a significant boost.
The technical achievement is difficult to overstate. Taxonomy is a fragmented discipline by nature, with thousands of specialists each maintaining expertise over narrow groups of organisms, from beetles to bromeliads. Knitting their independent databases into a single, consistent product required solving thorny problems of synonymy, where one species has been described multiple times under different names, and of classification, where competing arrangements of the same groups coexist in the literature. The result is today the most complete list of life on Earth, containing over two million accepted species names, literature references, millions of synonyms and a simplified classification served from a single data product that underpins biodiversity informatics worldwide.
Much of the organisation’s early success is credited to Frank Bisby of the University of Reading, who led Species 2000 from 1997 and steered it into the thriving federation of taxonomic initiatives its founders had envisioned. His sudden death in October 2011 was a serious blow, and the transition that followed tested the resilience of the project. Peter Schalk took over the leadership role and negotiated a stable institutional home for the Catalogue of Life, securing the position of Executive Editor Yury Roskov. That role, along with a data manager position, was funded through an endowment created by the David C. Eades Foundation for the Illinois Natural History Survey at the University of Illinois Urbana-Champaign, an endowment that remains in operation today.
In 2013, the Species 2000 secretariat moved to the Naturalis Biodiversity Center in Leiden, the Netherlands, embedding the project within one of Europe’s leading natural history institutions. That arrangement ended amicably by mid-2023, after which Species 2000 operated independently. By then, however, larger geopolitical forces were already reshaping the project’s future. The United Kingdom’s departure from the European Union on 31 January 2020 limited the ability of a UK-registered organisation to compete for research funding within the EU, a serious constraint for a body that depended on grants to maintain its data infrastructure.
The solution was the creation of a new legal entity inside the EU. After some delays related to the COVID-19 pandemic, the Catalogue of Life Foundation was established in May 2022 in the Netherlands as a not-for-profit organisation. From its Dutch base, the foundation could compete for European funding to improve the data product, modernise the technical infrastructure and sustain the mission of the Catalogue of Life. The board of Species 2000 agreed that the foundation would eventually take over all operations concerning the Catalogue of Life, setting in motion the orderly handover that has now concluded.
The closure itself was conducted with meticulous care. By late 2025, all outstanding funds from sponsors had been collected and all debts to creditors resolved, allowing the board of directors to begin winding up the organisation. Financial documents were sent to accountants and submitted to the UK Companies House by October 2025, and the bank accounts were closed. The membership was notified of the intent to dissolve in early December and given two weeks to comment; the board received only messages of goodwill in response. With every legal requirement satisfied, the Companies House notified the board of the organisation’s full closure on 5 May 2026.
For the global biodiversity community, the significance of this transition lies in continuity. The Catalogue of Life serves as the taxonomic backbone for the Global Biodiversity Information Facility, meaning that the names and classifications it publishes determine how hundreds of millions of species occurrence records are organised and interpreted. The former directors of Species 2000 congratulated the new foundation on securing new funding and on building an infrastructure capable of serving GBIF’s need for a stable taxonomic backbone, alongside robust new technical systems for delivering the data product.
The numbers tell the story of a project that kept growing to the very end. The most recent annual release of data through the Catalogue of Life website contained nearly 2.5 million accepted species names, a figure that continues to climb as taxonomists describe new species and resolve old synonymies. What began in 1996 as a federation of willing database builders has become an indispensable piece of global scientific infrastructure, and its stewardship now rests with the Catalogue of Life Foundation. The former board members of Species 2000 have expressed their best wishes to the new board for a fruitful continuation of the mission, ensuring that the most complete list of life on Earth will keep evolving long after the organisation that started it has passed into history.
