Utilizing available land efficiently in the cities helps in climate stabilization through carbon sequestration and conserves biodiversity, apart from providing many other ecosystem benefits. This study investigates the diversity and carbon sequestration in trees that are grown in different landscapes of cities such as residential area, avenue trees, parks, industrial area and around lakes in one of the wards of Bengaluru city. In the present study, 44 tree species belonging to 23 families were recorded among the different landscapes mentioned. Among the five landscapes studied, the highest tree population is noticed among the avenue trees. Pongamia pinnata is the most dominant tree species. The residential area had the highest tree biomass and Parkshad the lowest biomass assessed from the top ten dominant trees that constituted about 82 per cent of the population. Total carbon sequestered by the trees from the study area is 505 tons and total CO_2 sequestered is 1852 tons. The total amount of carbon stocked in five landscapes varied from 155 tons km~(-1) in the industrial area, followed by avenue trees (143 tons km~(-1)) and least was found around the lakes (26 tons km~(-1)). Thus, maintaining trees in urban areas help in conserving biodiversityand ameliorating climate.
