This study applied research - development is in terms of analytical methods and field study in the region six Municipality Tehran (keshavarz-blvd). To analyze the data and test reviews normalization of SPSS software in the form of non-parametric tests such as “ Kolmogorov–Smirnov test” is used. To analyze the data the first hypothesis t-test and ANOVA were used for the second hypothesis. The second hypothesis test, T-test and analysis of bivariate correlation (Pearson correlation coefficient) is used. The population of this research is Ulmus tree keshavarz-blvdin Tehran. Ten samples were randomly selected to have an access way. Some processes are influenced by the light: germinate, grow and produce the pigment that consume a small amount of light energy. Energy from sunlight to convert water into steam that cell walls makes the water flow in the plant. We find that the leaves of the trees in the snow, the area collect snowflakes by plants grown and the reasons for the growth over tree roots is weak and power to keep the trunk so heavily does not exist then the disaster with a light snow falls.
