What Happened

India added 709 new animal species and 353 plant taxa to its national biodiversity databases in 2025, as documented by the Zoological Survey of India (ZSI) and the Botanical Survey of India (BSI) respectively.
Of the 709 new faunal entries, 483 are species completely new to science (first-ever discovery globally), while 226 are species recorded in India for the first time (previously known from other countries).
The BSI's 353 new plant taxa include 14 infraspecific taxa (sub-species and varieties), supplementing species-level additions.
Kerala recorded the highest contribution to the faunal database with 98 new animal species, reflecting its exceptional biodiversity in the Western Ghats hotspot.
Arunachal Pradesh was the leading contributor to the floral database with 49 new plant discoveries, consistent with its position as one of India's most botanically diverse states in the Eastern Himalayan hotspot.
With these additions, India's total documented faunal diversity has reached 1,05,953 species — a milestone figure reflecting decades of survey work.
The Union Ministry of Environment, Forest and Climate Change formally announced the findings, coinciding with the Zoological Survey of India's 111th year.

Zoological Survey of India (ZSI) — Mandate and History

The Zoological Survey of India (ZSI) is the premier government institution for faunal research and taxonomy in India, established on 1 July 1916 under the Ministry of Environment, Forest and Climate Change. Its genesis can be traced to the Zoological Section of the Indian Museum in Calcutta (1875), which itself grew out of the Asiatic Society of Bengal founded by Sir William Jones in 1784.

ZSI's mandate: To survey, explore, and conduct research on India's wildlife; to maintain the national faunal database; to publish species inventories and monographs.
Headquarters: Kolkata; with 16 regional centres/field stations across the country.
ZSI publishes the "Animal Discoveries" report annually, documenting newly described and newly recorded species.
In 2026, ZSI is celebrating its 111th year, marking the occasion with the Animal Taxonomy Summit 2026.
ZSI operates under the same ministry as the National Biodiversity Authority (NBA) and Wildlife Crime Control Bureau (WCCB).

Connection to this news: The 709 new faunal species are officially validated and documented by ZSI, making ZSI's institutional credibility and mandate directly relevant to understanding how India's faunal records are maintained and expanded.

Botanical Survey of India (BSI) — Mandate and History

The Botanical Survey of India (BSI) is the national organisation for survey, inventory, and research on India's plant diversity, established in 1890. It predates ZSI and served as the institutional model for the latter's creation. BSI operates under the Ministry of Environment, Forest and Climate Change.

BSI's mandate: Survey the flora of India, document new plant species, maintain herbaria, and publish floral monographs.
Headquarters: Kolkata (Botanical Garden, Howrah); with 11 regional centres across the country.
BSI publishes "Plant Discoveries" annually, parallel to ZSI's "Animal Discoveries."
BSI maintains the Botanical Garden of Howrah (founded 1787), one of Asia's oldest botanical gardens.
BSI and ZSI together maintain India's national biodiversity inventory, informally called "Fauna of India" and "Flora of India."

Connection to this news: The 353 new plant taxa are BSI's contribution to the 2025 biodiversity count, and BSI's annual Plant Discoveries report is the authoritative source for floral additions.

India as a Megadiverse Country

A "megadiverse country" is a term coined by Conservation International (CI) to identify countries that harbour the majority of Earth's species and a large number of endemic species. There are 17 recognised megadiverse countries in the world, accounting for approximately 70% of global biodiversity.

The 17 megadiverse countries include: Australia, Brazil, China, Colombia, Democratic Republic of Congo, Ecuador, India, Indonesia, Madagascar, Malaysia, Mexico, Papua New Guinea, Peru, Philippines, South Africa, United States, and Venezuela.
India, despite covering only 2.4% of the Earth's land area, accounts for approximately 7–8% of the world's recorded species.
India has 4 of the world's 36 biodiversity hotspots: Western Ghats & Sri Lanka, Eastern Himalayas, Indo-Burma (northeast India), and Sundaland (includes Nicobar Islands).
India hosts approximately 91,000 documented animal species and 45,500 plant species across 10 biogeographic zones, with the newly updated faunal count now at 1,05,953.
Endemism levels: ~12.6% of mammals, 45.8% of reptiles, 55.8% of amphibians, and 33% of Indian plant species are endemic.

Connection to this news: The annual addition of hundreds of new species underscores why India qualifies as a megadiverse nation — its biological richness is still being actively inventoried, and each year's discoveries revise upward the total species count.

Biodiversity Hotspots and Regional Discovery Leaders

The geographic pattern of discoveries — Kerala (Western Ghats) and Arunachal Pradesh (Eastern Himalayas) — reflects India's two most species-rich regions, both of which are global biodiversity hotspots.

Western Ghats: Declared a UNESCO World Heritage Site in 2012; harbours over 5,000 species of flowering plants, 139 mammal species, 508 bird species, 179 amphibian species — with exceptionally high endemism in amphibians and reptiles.
Eastern Himalayas (including Arunachal Pradesh and Sikkim): Part of the Eastern Himalayan hotspot, one of the world's richest areas for plant diversity; Arunachal Pradesh alone is estimated to have over 5,000 plant species.
Meghalaya and Andaman & Nicobar Islands are other consistent contributors to annual species discoveries.

Connection to this news: Kerala's 98 new animal species and Arunachal Pradesh's 49 new plant species are not accidental — they reflect the under-surveyed but extraordinarily rich biomes that ZSI and BSI field teams prioritise.

Legal Framework for Biodiversity Protection

Two key laws govern biodiversity documentation and protection in India:

Wildlife (Protection) Act, 1972: Provides legal protection to wild animals and plants through six Schedules (I to VI, post-2022 amendment reducing from earlier structure). Schedule I and II species receive absolute protection; Schedule III and IV receive partial protection; Schedule V covers vermin; Schedule VI covers specified plants. New species added to ZSI/BSI databases may subsequently be listed in these schedules.
Biological Diversity Act, 2002: Enacted to implement India's obligations under the Convention on Biological Diversity (CBD, 1992). Establishes: National Biodiversity Authority (NBA) at central level; State Biodiversity Boards (SBBs); and Biodiversity Management Committees (BMCs) at local body level. Regulates access to biological resources and mandates benefit-sharing with local communities. The 2023 amendment to the Act streamlined certain provisions, including related to research and traditional knowledge.

Connection to this news: Newly documented species are first recorded in ZSI/BSI databases; their protection and any access-sharing agreements are subsequently governed by WPA and BDA frameworks.
