Ecosystems Services and Functions of Urban Green Spaces

Trees in urban systems provide a variety of ecosystems services including biodiversity conservation, removal of atmospheric pollutants, oxygen generation, noise reduction, mitigation of urban heat island effects, microclimate  regulation, stabilization of soil, ground water recharge, prevention of soil erosion, and carbon sequestration. Wildlife sanctuaries are undeniably important for biodiversity conservation tools.  The urban trees also remove large amounts of air pollution (O3, PM10, NO2, SO2, CO) improving urban air quality.


The Urban Heat Island is a phenomenon whereby temperatures in urban areas are warmer than the surrounding rural countryside, often by several degrees. As urban green spaces and urban forests increase, evapotranspiration rate increases .Thus, a common measure to mitigate urban heat island effect is to increase urban green spaces.
