Also, trees are significant indicators that define the quality of urban life due to their aesthetical, ecological, psychological, hygienical and multifunctional aspects. Therefore, tree culture in urban life becomes an important area of activity for local authorities to conduct. The benefits of trees reflect the real and irreal values of planting in landscape projects. The real value of growing a tree is determined by the cost made in the beginning for a certain period. However, aesthetical, ecological, sociocultural, psychological and hygienical irreal value is greater and more important than the real. The values which can be calculated according to some approach, are indicators of the purpose of urban tree culture. In this paper, it is aimed to demonstrate the functions of urban trees in cities, protection, evaluation and appraisal approach.
