But as the data below shows, slum encroachment at Sanjay Gandhi National Park at Borivali in the western suburbs has taken a toll on its flora and fauna.

Citizens’ speak

“We have maintained the area and boundaries of the National Park and we also carry out regular census. There are few endangered species and major wild animals who are kept in captivity.”

Naikwadi, Assistant Chief Conservator of Forests

“The state of the park is affected due to encroachments and infrastructure development in some areas of the park. The forest cover is the same but the open spaces are encroached upon. Few endangered species like fox and jackals which were earlier spotted at the park are not to be seen now.”

Krishna Tiwari, an activist

“ The number of people and youngsters visiting the park have increased which makes it difficult to spot the wildlife. We have to search for varied species of birds and patiently wait to get a close view.”

Omkar Adhikari, a photographer and frequent visitor

“The wildlife at the park should increase. I could not spot a lion during the lion safari ride. Development, urbanisation and overcrowding at the park has served as a threat to the animals who then prefer to stay in their closed circuits.”

Shraddha Apte, a frequent visitor
