Several species of beautiful birds have been forced into leaving the Garhi Mandu city forest area due to rise in pollution and loss of habitat. The forest area is spread over 894 acres in northeast Delhi.
Locals and civic workers are dumping debris and plastic waste in a huge natural wetland, which borders as much as 60 per cent of the south and eastern boundaries of this protected forest. Regular burning of garbage is causing severe air and water pollution.
On the filled up land, vegetable cultivation has also started. Water from the wetland is being regularly pumped out for cleaning vehicles and cultivation. Regular fishing is also disturbing the habitat and food chain of thes birds by causing the wetland to dry up. Open thoroughfare and playgrounds around the wetlands have also disturbed nesting.
“Resident waterbirds scared away so far include oriental darter, spot-bill duck, great and little cormorant, cinnamon bittern, white-throated kingfisher, purple swamphen, Indian moorhen,” said ecologist TK Roy. Birds, whose nesting has been disturbed, include green bee-eater, bank mynah, dabchik, and blackwinged still.
“The wetland attracts several species but despite repeated requests from environmentalists, the government is yet to notify the wetland. That’s why it’s unprotected and officially not part of the city forest,” he said.
“While so much money is being spent to save wetlands, a natural one along this city forest has been left neglected. Once the wetland is notified by the government for its protection, Garhi Mandu City Forest will be combined forest land of terrestrial and wetland habitats,” he said. The city forest is rich in biodiversity. The first-ever bird count at Garhi Mandu, conducted on February 24 this year, found 90 species, including 26 migratory and several threatened birds. “We found 33 species of waterbirds, including 13 migratory ones. Of the 57 species of terrestrial birds, 13 were migratory,” said Roy, who conducted the count.
The city forest shares its eastern boundary with colonies such as Shastri Park, Jagjit Nagar and Usmanpur along the Pushta Road which branches off National Highway 24. On the other side, it borders the left bank of the Yamuna.
