India's Environment Ministry and Wildlife Institute of India (WII) released the results of the first-ever DNA-based elephant census on October 15, 2025, putting the wild elephant population at 22,446 — an 18% decline from 2017 estimates. The census, called the Synchronous All-India Elephant Estimation (SAIEE) 2021-25, collected 21,056 dung samples across 670,000 km of forest trails and used DNA fingerprinting to identify 4,065 unique elephants. Karnataka has the largest population (6,013). The Western Ghats (11,934) and Northeast (6,559) hold the most elephants. Threats include habitat fragmentation, mining, railway collisions, and human-elephant conflict.

Frequently asked questions
What is the SAIEE 2021-25 census and what methodology did it use?
SAIEE stands for Synchronous All-India Elephant Estimation 2021-25, India's first-ever DNA-based elephant census conducted by the Environment Ministry and the Wildlife Institute of India (WII). It collected 21,056 dung samples across 670,000 km of forest trails and used DNA fingerprinting to identify 4,065 unique elephants, making it far more precise than earlier visual-count methods.
What did the SAIEE census reveal about India's elephant population?
The SAIEE 2021-25 census, released on October 15, 2025, put India's wild elephant population at 22,446 — an 18% decline from the 2017 estimates. Karnataka has the largest population at 6,013, followed by the Western Ghats region (11,934 total) and the Northeast (6,559). The decline points to growing threats from habitat loss, mining, and human-elephant conflict.
Why is DNA fingerprinting considered superior to earlier elephant census methods?
Earlier elephant counts relied on visual observation or footprint analysis, which led to double-counting and significant inaccuracies. DNA fingerprinting, using dung samples collected along thousands of forest trails, allows each individual elephant to be uniquely identified regardless of sighting conditions — resulting in a far more accurate and scientifically robust population estimate.
What are the major threats to elephant populations in India according to the census?
The SAIEE census identified habitat fragmentation, mining activities, railway line collisions, and human-elephant conflict as the four major threats as important pressures on elephant conservation in India. Encroachment into elephant corridors and loss of forest cover are the underlying drivers of habitat fragmentation and increased conflict.
Which state has the largest elephant population in India and which region comes second?
Karnataka has the largest elephant population in India at 6,013, as revealed by the SAIEE 2021-25 census. The Western Ghats region as a whole accounts for 11,934 elephants, making it the most elephant-rich biogeographic zone in India, followed by the Northeast region with 6,559 elephants.
