PRAYAGRAJ, May 23 -- A major biodiversity conservation project being developed in Pratapgarh district under the Namami Gange scheme is nearing completion, officials said. The Swami Karpatri Ji Maharaj Biodiversity Park is coming up in the Chilbila forest area to restore the ecology of the Sai river and revive the region's historic green cover. According to officials, the project was earlier expected to be completed by September this year. However, a three-year extension has now been granted after authorities observed healthy growth of several rare plant species inside the park. Divisional forest officer Ashutosh Gupta said the biodiversity park is being developed over nearly 25 hectares, including a four-hectare wetland area, at a cost of Rs.5.5 crore. He said most of the work has been completed and fencing work is currently in progress to secure the site. The park includes several attractions such as a butterfly park, scented garden and birdwatch tower. Thematic green spaces including Nakshatra Vatika and Panchvati Vatika have also been developed. A nature trail and wooden bridges have been created to improve the visitor experience. Officials said work on tourist facilities such as parking areas and selfie points is still pending. Plans also include a water lily conservation centre, herbal gardens and a four-kilometre-long nature trail. The project was launched in March 2024 in the Chilbila forest area of Pratapgarh. Officials said it is expected to promote eco-tourism, create local employment opportunities and strengthen environmental conservation in the region. DFO Ashutosh Gupta said the main aim of the project is to restore the Sai river ecosystem and bring back native plant species, birds and butterflies that have gradually disappeared from the riverbank area over the years. Officials added that dense plantations along the river will help create a safe habitat for aquatic life and wildlife. Trees, grasses and vegetation planted in the park are also expected to act as natural filters and prevent soil, pollutants and chemical waste from agricultural fields from entering the river during rainfall. The project also includes ponds, water retention zones and check dams for water conservation. Officials said these structures would help improve groundwater recharge around the Sai river and maintain water flow during summer months. Deep-rooted trees planted along the riverbank are also expected to reduce soil erosion and lower flood risks in nearby areas....
