China Species List 2026 Adds 6,154 New Species
On May 22 — the 26th International Day for Biological Diversity — the Biodiversity Committee of the Chinese Academy of Sciences (CAS) officially released the 2026 Edition of the China Species List, adding 6,154 new species and infraspecific taxa to the country’s biodiversity inventory. The updated catalog now contains a total of 168,871 entries, including 155,266 species and 13,605 infraspecific units, according to the Chinese Academy of Sciences.
A Landmark Update for Global Biodiversity
The 2026 edition represents a significant expansion of taxonomic coverage, with major additions across multiple biological kingdoms. The animal kingdom saw the largest increase, with 3,380 new species and 477 new infraspecific units. The fungal kingdom added 3,114 species, while the plant kingdom contributed 431 new species.
For the first time, the list includes Rotifera (476 species) and Collembola (734 species) — entire taxonomic groups that had previously been absent from the national inventory. The insect additions were particularly substantial, with over 2,000 new species across orders including Siphonaptera, Hymenoptera, Hemiptera, and Coleoptera, as Xinhua News Agency reported.
Among vertebrates, amphibian species increased by 48 to a total of 767, while reptile species grew by 40 to reach 731. The fungal kingdom underwent significant classification system adjustments, resulting in a net increase of over 1,800 species and infraspecific units.
Collaborative Scientific Effort
The 2026 edition was led by the Institute of Zoology, CAS, in collaboration with five other CAS institutes: the Institute of Botany, Institute of Microbiology, Institute of Oceanology, Chengdu Institute of Biology, and Kunming Institute of Zoology. The project received support from the CAS Strategic Biological Resources Program and the National Basic Science Public Science Data Center, as detailed by People’s Daily.
A Unique Global Contribution
China remains the only country in the world that publishes a comprehensive national species list on an annual basis. Since its experimental release as a CD-ROM in 2007, the China Species List has grown into a globally significant resource. The data is freely available for download at the Species 2000 China Node.
The impact of this initiative is substantial: total downloads of the China Species List have exceeded 24 terabytes, online species page visits have surpassed 27 million, and the list has been cited in over 1,500 domestic and international journals and monographs.
Scientific and Conservation Significance
The expansion of taxonomic coverage to include previously underrepresented groups like rotifers and springtails (Collembola) marks an important step toward a more complete understanding of China’s biodiversity. These tiny organisms play critical roles in aquatic and soil ecosystems, respectively, and their inclusion provides researchers with a more comprehensive baseline for ecological monitoring.
Comprehensive species inventories are essential for identifying biodiversity hotspots, assessing conservation status, planning protected area networks, and monitoring the impacts of climate change and habitat loss. The list provides critical baseline data for China’s ecological civilization (生态文明) initiatives, which integrate environmental protection into national development planning.
As the Chinese Academy of Sciences stated in its release, “The continuous updating of the China Species List not only consolidates China’s biodiversity ‘family assets’ but also effectively transforms China’s commitment to the Convention on Biological Diversity into a public good benefiting the entire world.”
Steady Growth Trajectory
The 2026 edition continues a pattern of consistent annual growth. After major jumps of over 10,000 new entries in both 2022 and 2023, the pace has stabilized at approximately 6,000-6,700 new additions per year in the 2024-2026 editions. This sustained growth reflects ongoing field surveys, taxonomic revisions, and the integration of new research findings.
A Benchmark for Biodiversity Documentation
China’s annual species list initiative sets a global benchmark. While many nations maintain biodiversity databases, none publish a fully updated national checklist on an annual basis. The open-access model — providing free downloads to users worldwide — transforms national scientific investment into a global public good, directly supporting the objectives of the Kunming-Montreal Global Biodiversity Framework.
What’s Next
The China Species List is expected to continue its annual release cycle, with future editions likely to expand coverage into additional under-documented taxonomic groups such as marine invertebrates and soil microfauna. As digitization efforts advance, the platform aims to deepen the integration and sharing of species information worldwide, supporting both biodiversity research and conservation policy decisions. With over 1,500 academic citations already, the list is becoming an indispensable reference for scientists studying everything from evolutionary biology to climate change impacts on species distribution.
