Jammu and Kashmir does not support natural population of Elephants.
The north east indian states of Assam, Arunachal Pradesh, Mizoram, Meghalaya and Tripura together with West Bengal account for 30.1% of the elephants.
The Indian elephant (Elephas maximus indicus) is one of three recognized subspecies of the Asian elephant and native to mainland Asia. Since 1986, Elephas maximus has been listed as Endangered by IUCN as the population has declined by at least 50% over the last 60 to 75 years or three generations. Asian elephants are threatened by habitat loss, degradation and fragmentation.
