Chilli-based repellents have shown promise as deterrents against crop-raiding elephants in Africa. The authors experimented with ropes coated with chilli-based repellent as a cheap alternative to existing elephant crop raid deterrent methods in India.
Ranging behaviour of the Asian elephant (Elephas maximus) was studied using radio telemetry in the Nilgiri Biosphere Reserve had home ranges of over 500 sq km. These sizes are much larger than those defined by earlier studies. The study ranged across the three southern states of Tamil Nadu, Kerala and Karnataka.
