Abstract :

AbstractAn important charactristic of the public domain is street and street trees show a monitoring of the urban tissues. Urban green space due to the enviromental values is the main characteristic of each city. The first step for all of the management and planning of urban green space, knowing information about street trees is the first step to proper management. Due to the recent events have taken the risk creation of trees in the babol city. In this research, the assessment of hazardous pinus (Pinus eldarica Medw) in the Felestin street to University of Medical Sciences and Intersection of Farhang to Ghaziketi square, and all tree perfect inventoried. Trees were carried out on both sides of Farhang and Farmandari Street. Detected the types of tree defects were using risk criteria. Totally, 120 trees were sampled. After the analysis of data classify the level of hazardous in each criterion. The results showed that the dead woods and root problems tree structure are the main tree defects (with values of 75 and 65 percent of all sample trees, respectively), while weak branch unions and decay have less importance. Regarding to combination of tree defects, 12 trees (10% of all trees) were classified as very dangerous and must be removed. Other tree (average hazardous) must be crown pruning.
