Wild Elephants in Southern India Expanding Range After Two Centuries
Elephants are the biggest land animals, and they usually stay in forests where they have lived for a long time.
Scientists in southern India found that wild elephants are now moving to new places.
These new places had no elephant sightings for more than 200 years.
One such place is the Oddanchatram forest range, where British records showed elephants in 1812.
After 1812, elephants were not seen there again until around 2006.
Between February and July 2016, scientists counted 18 elephants of different ages in the foothills of that forest.
The elephants probably came from the Anamalai Tiger Reserve and the Chinnar Wildlife Sanctuary.
There are two possible reasons elephants are moving: their old forests may not have enough food, or there may just be too many elephants.
When elephants go to new places, they can sometimes come near people's homes and farms.
That is why experts say we need a plan to manage elephants in their new areas so people and elephants can live safely.
Wild elephants in southern India are dispersing into areas where their movement had not been recorded for more than two centuries.
Between February and July 2016, researchers found 18 wild elephants of different age groups in the foothills of Oddanchatram forest range.
British-era records documented elephants in the Oddanchatram area in 1812, with no records of movement there again until 2006.
The Oddanchatram elephants likely came from the Anamalai Tiger Reserve in Coimbatore and the Chinnar Wildlife Sanctuary in Kerala.
Researchers say the range expansion may signal a lack of resources in traditional habitats or a growing elephant population.
- Who
- Wildlife biologists Dr. B. Ramakrishnan (Government Arts College, Ooty) and Dr. G. Sivasubramanian (Kongunadu Arts and Science College, Coimbatore), who conducted the dispersal studies.
- What
- A study documenting wild elephant range extension into southern Indian areas, such as the Oddanchatram forest range, where no elephant movement had been recorded for over two centuries.
- Where
- Southern India, including the Oddanchatram forest range (Dindigul forest division, Tamil Nadu), plus dispersal from Hosur and Bannerghatta into Andhra Pradesh and from north Canara into Maharashtra and Goa.
- When
- The study covers the recent decade; 18 elephants were recorded in the Oddanchatram foothills between February and July 2016.
- Why
- Range extension may be caused by a lack of resources in traditional habitats or a growing elephant population, and management plans are needed to avoid conflict with people in the new areas.
Resource Scarcity
Population Growth
Why are elephants extending their range?
Resource Scarcity
Elephants are moving into new areas because their traditional natural habitats lack sufficient resources, forcing them to seek greener pastures.
Population Growth
Elephants are moving into new areas because their population has grown, and numbers have expanded beyond the capacity of their traditional habitats.
