Sunder Nursery is a 90-acre heritage park and city park located in New Delhi, India. It was established in the early 20th century as a plant nursery to propagate plants for New Delhi. Since 2007, the Aga Khan Trust for Culture has partnered with the government to transform the overgrown nursery into a public park and arboretum. Over 20,000 trees from 280 species have been planted, creating habitats for over 80 bird species and 40 butterfly species. The landscape master plan was designed to include formal gardens around historic monuments and a 30-acre microhabitat zone representing different ecosystems of Delhi.
