Yamuna Biodiversity Park

Emerging as the capital's most visited public place and prominent center for learning and understanding the environment, the Yamuna Biodiverstity Park has become a home for biologically rich wetlands, grassland communities, a wide variety of fruit yielding species and an abundance of medicinal herbs. The Park also comprises a native flora and fauna which used to exist a 100 years ago and then became extinct locally. It further, acts as a natural conservation site for specific group of endangered plants. The Yamuna Biodiversity Park is presently spread over an area of approximately 457 acres near Wazirabad village on the flat alluvial plains of the Yamuna and can be approached:

(i) from East Delhi through Bhajanpura,

Yamuna Biodiversity Park, Delhi

The park features two major zones - the visitor zone and the nature reserve zone.
The front portion of the Yamuna Biodiversity Park, a 220m southward and 140m northward stretch from the main entry gate with 20-30m width is demarcated as Domesticated Biodiversity Zone. Enclosed by a hedge of poplar, it features plants like Ailanthus, Butea and Bauhinia that have a continuous seasonal interest due to their long flower production throughout the season. The outer iron fencing is embraced by multi-coloured climbers like Jasmine and Quisqualis with the same theme of continual luxury.

Located at the main entrance, at the southward end, are three snack bars, a drinking water facilities and three resting places covered with the vines of Argyreia nervosa, Jasminum sambac and Petrogea volubilis. Just past the entry pocket and to the right is a “Welcome Rock facet” representing the origin of the Ganga and Yamuna and their convergence at Allahabad. A trail further leads to the Bambusetum, the Nature interpretation Centre, the Conservatory of fruit yielding species, the Migratory duck’s wetland and the Nature Reserve area.

Nature interpretation Centre is a beautiful classical building with elegant lighting, a red carpet floor, attractive interior designs, panels depicting various biodiversity levels, touch screens, and visual-aids that provide an insight into the basic concepts of biodiversity.

On the left, the landscaping provides two shallow valleys representing rangelands with 10 mounds representing different ecosystems present from the foothills of the Himalayas (Siwaliks) through the Yamuna basin, till the point of confluence of the Yamuna and Ganga. The first rangeland i.e. Rangeland 1, corresponds to an exclusive Sporobolus diander dominance while the second one i.e. Rangeland 2 showcases a mixture of native tropical grasses such as Dichanthium, Chrysopogon, Vetiveria, and Bothriochloa. These two rangelands are bordered by a serpentine trail. The first loop of the trail connects Rangeland 1 with Herbal garden, sacred grove and Rangeland 2 while the other loop leads to the butterfly conservatory and amphitheatre. The amphitheatre is an open auditorium, the herbal garden offers a collection of about 450 plant species with healing properties.

On this loop trail one sometimes comes across bouncing hares and has a chance to watch red-wattled lapwings and other grassland birds. The exit of the Butterfly Conservatory on the west side leads to Sacred Grove and the Gene Bank of Petro- and Oil-yielding and other plants through the Bamboo Bridge from which one can enjoy a view of the resident ducks’ wetland and a wide variety of fishes.

Surrounding the valley are the Ten Mounds which illustrate the different forest ecosystems in its miniature form found all along the Yamuna River Basin. The composition of forests, as in nature, consists of three to four layers: a tree canopy that supports climbers and provides shade for the middle storey tree layer and shrub layer which in turn protect the ground-cover of herbs and grasses.
