 Urban green areas in Sarajevo are of the most importance for the overall appearance of the city and the quality of life in it. In recent years there has been a decline in the area under vegetation. The main reason for the loss and degradation of green areas is anthropogenic factor which predisposes urban greenery with its activities to various other biotic and abiotic factors. Air pollution, drought, high temperatures, soil and water pollution are group of abiotic factors which synergetic cause physiological changes in plant species. The fall of physiological resistance causes exposure of plants to biotic factors, especially insects, fungi, and recently mites.
 In this paper, the research was conducted in order to determine the identification of harmful species of mites on the linden trees and determine the intensity of infection. Linden trees are designed as an avenue that stretches from Suada and Olga Bridge to the TV home in Alipašino Polje. Identification was based on symptoms established on the leaf material directly in the field and in the laboratory with the use of microscopes and binoculars. Laboratory studies were carried out at the Faculty of Forestry in Sarajevo. The intensity of infection of trees was determined HAWKSWORH'S six class system (1986).
 A total of 200 trees were analyzed of which is the 136 infected by phytophagous mites. We identified five types of mites. Found species belonged to the family Eriophyidae and Tetranychidae. Following types of mites are identified from the first family: Eriophyestiliae (Eriophyoidea), Eriophyestiliaelateannulatus (Eriophyoidea), Eriophyesexilis (Eriophyoidea), and Eriophyesleiosoma (Eriophyoidea). From other family revealed the presence of mite Eotetranychustiliarum (Tetranychoidea).
 The result of research conducted in the period from May to August showed a tendency of all recorded species of mites to the lower parts of the tree crown and going to the higher parts their numbers are decreasing.

Urban green areas in Sarajevo are of the most importance for the overall appearance of the city and the quality of life in it
Urban green spaces are public spaces located in urban areas, which are mostly covered with vegetation and used directly for active and passive recreation, or indirectly through the benefits they have for the urban environment, which are available to the citizens and serve the different needs of citizens, which are enhancing quality of life in urban areas (ČOMIĆ et al, 2009).Urban green spaces are important elements of each city
Most of the harmful species is widespread, but some are economically more important than the other and exhibit different harmful effects depending on the characteristics of agro ecosystems in different climates, in terms of plant species grown in the open field (PETANOVIĆ et al, 2010)
Summary

The statistical analysis of the studied parameters were carried out using OneWay ANOVA in statistical program Statgraphics Plus. The significance of differences between the individual categories of the tested parameter was determined using the Fisher LSD test. Results of statistical analysis of the impact of the site and the species of lime on the size of the average index of infection are given in Tables 2 and 3.
