Numerous studies have been conducted on urban trees, analysing such topics as composition, thickness, height and health status for purposes of tree management. Through a review of the literature, we not only focus on the aesthetic aspects of urban trees, but also analyse their environmental, social and economic benefits. The review is divided into three sections. First, studies on the environmental benefits of urban trees were reviewed, including the biotic and abiotic factors that are closely related to the quality of life in urban areas. These benefits include air, temperature, air pollution, water conservation and increased biodiversity. Secondly, the social benefits of urban trees for the community were analysed, stressing the importance of trees for citizens’ physical and psychological well-being. It has been shown that urban areas that are well provided with trees usually have lower levels of violence and crime. Thirdly, the review shows that urban trees can provide direct economic benefits such as increased property values. The review clearly demonstrates that urban trees not only contribute to the aesthetic quality of open urban spaces, but are strategic to improving the quality of life and sustainability of urban areas.Peer reviewed
