Urban parks are significant in various ways. Apart from their recreational, health and fitness values, they contribute to the ecology of urban areas by maintaining the biological diversity of human interfered areas. They act as critical habitat spaces for urban wild life. Their role in sequestering carbon dioxide and acting as sinks for pollutants is well understood. The current paper is an effort to understand the species composition and carbon sequestering potential of a park in Bengaluru. The study reveals that the ratio of native and exotic species in the park is 51.82: 48.18 and its carbon sequestration potential was estimated to be 54,540.1 tonnes.
