Mumbai: The sudden spurt in leopard attacks and increased instances of leopard spotting around Sanjay Gandhi National Park (SGNP) are primarily due to the high density of human population and concentration of small prey on the periphery, a year-long study has revealed.

The study, “Mumbaikars for SGNP”, was conducted by the forest department and the Centre for Wildlife Studies, Bangalore and found that there are at least 21 leopards in the national park.

Mumbai: Mangroves in the city are in peril. Green cover in Mahul, Chembur has come under threat after toxins were dumped there last week.

The incident was reported behind a Slum Rehabilitation Authority building (SRA) in Mahul where trucks have reportedly been discarding oil residue on the mangroves. Locals said that the activity has been going on since the last one week. The matter was reported to the forest department and the mangrove cell has already inspected the area and taken samples. However, those dumping the deposits remain unidentified.
