Green areas near communication routes not only retain rainwater, beneficially influence on the local microclimate but cleanse the air effectively too. Greenery planted along the roads and streets is exposed to biotic and abiotic environmental factors. Abiotic stress factors such as air and soil desiccation or extreme temperature have the greatest impact on plant development. The use of chemical and mechanical means to keep roads in good condition in winter negatively affect on the condition of trees and shrubs along the road zone. Proper management of green areas is to weaken the negative impact of urbanization, providing the water needed for the growth of plants and reducing maintenance costs. The basic functions of greenery and advantages of plants presence in urban landscape were presented in this paper.
