REVIVING LOST ECOLOGICAL HERITAGE

With its woods and wetlands, the Yamuna Biodiversity Park (YBP) has not only caught the fancy of humans but also hasbecome the winter habitat of many migratory birds, a claim that remains unrivalled in Delhi. Thanks to the intervention of theCentre of Environmental Management and Degraded Ecosystem (CEMDE), a piece of land that was lying barren until 2002has now grown into an ecological paradise teeming with thousands of species of flora and fauna.

Tucked away on the outer ring road near Wazirabad in north Delhi, YBP is spread over an area of 157 acres. It is a jointeffort of DDA and CEMDE. CEMDE gives credit to the government for supporting the project. C. R. Babu, professor,CEMDE, says. The city has lost most of its ecological heritage. Almost the entire forest cover is lost. The big cats that usedto roam around the Red Fort have become extinct. The city needed to revive its ecosystem and that is precise what we arestriving to achieve at YBP.

According to the claim of scientists involved with YBP, after completion, the project will be richer than any of the bio-parks in the country. The development work on the land that was allotted in 2002 is almost complete.

The first phase of the development phase is over. But we still prefer to cal it the middle level of the project as he treesare yet to attain their maximum height and other changes that we made in the park are settling down. Avers Anupam Joshi,scientist in charge of the project. Scientists claim that there has been a rapid increase in the forest cover and a naturalecological system is setting in. Says Ekta Khurana, field scientist. We study the relations between different specie of plantsand replicate them at the YBP. The fact like animals like wild cat, neelgai, peacocks and about 5 species of snakes havemade the park their home is proof that we have been successful in creating the eco system.

Beside the forest cover, the artificial covered wetlands have become a major draw for the migratory bird and students.The YBP boasts of two wetlands. The lake like wetland with a deep surface is designed to suit the needs of migratory birdsthat are dependent on deep water bodies for their existence and feeding while the shallow surface wetland is a river likewater body stretching up to .8 km. It is not surprising then that the YBP has become home for over 200 species of migratorybirds whose population after November is expected to cross 5000.

Recently DDA allotted another 300 acres of land to YBP, taking it closer to the Yamuna riverbed. Since the area is lowlying, scientist say 60% of the 300 acres will be developed into a wetland, thereby creating a bird sanctuary on the lines ofthe Bharatpur bird sanctuary. Only this one would be better.

The YBP will be open to the public by 2010, but already educational trips for academics and students have beenpermitted. Besides it has done a world of good to the eco system of Delhi, especially the north.

Questions:

1. In the light of above case, discuss how important role can be played by Government bodies in protecting environment.2. What is the need of balancing various ecosystems of earth?3. What more can be done to increase the losing bio-diversity in different parts of the country due to massive consumption

patterns and affluence?
