Urban forest has a significant impact on the conditions and quality of urban area residents’ life (Novak, Crane, 2008). Benefits from urban vegetation, known in the literature as ecosystem services, are now possible to examine and measure thanks to tools such as I-Tree Eco. Studies on the impact of vast urban green areas on climatic conditions and air quality in the city are becoming more and more popular. The results of these studies indicate that green areas act as a kind of filter catching pollutants and can affect the climate not only around their crowns but also at longer distances ranging from 100 to 500 m from their location (McPerson, Rowntree, 1993). The article presents the results of pilot studies based on the i-Tree Eco method applied for ecosystem services provided by the Park Praski in Warsaw.
