With reference to Indian elephants, consider the following statements: 1) The leader of an elephant group is a female. 2) The maximum gestation period can be 22 months. 3) An elephant can normally go on calving till the age of 40 years only. 4) Among the States in India, the highest elephant population is in Kerala. Which of the statements given above is/are correct?

The correct answer is A (1 and 2 only).

• Statement 1 is correct. An elephant herd is led by its oldest female, the matriarch. Her memory of water sources, migration routes and past danger is why herd behaviour in conservation work centres on her.
• Statement 2 is correct. Elephant gestation is about 18 to 22 months, the longest of any land mammal, and this long investment in each calf shapes their slow population growth.
• Statement 3 is wrong. Female elephants can calve well beyond 40, typically into their fifties and sometimes later. The 'only up to 40' idea is a common distortion.
• Statement 4 is wrong. In the 2017 synchronous elephant census, Karnataka had the highest population, followed by Assam, with Kerala well behind. Verify against the latest census before using the figures in an answer.

The core concept is elephant ecology and Project Elephant under the Wildlife Protection Act, 1972 and the Ministry of Environment, Forest and Climate Change. For Mains, link this to human-elephant conflict and corridor management.

Trap: Aspirants often assume Kerala leads because of its famous elephant tradition and high-profile sanctuaries. Population rankings are a data question, not a cultural one.
