In order to perserve quality of cultivated trees, towns need to systematically manage and look after green areas. Thus, a concept for maintenance of green areas has been developed, in which the green areas in Litoměřice were divided into eight zones. This concept includes recommendation of suitable selection of trees and their length of life cycle. Concept also presents development of individual zones depending on their character and utilization.

Proposal brings changes into concept of urban green areas maintenance, which needs also the inhabitans understanding and change of their attitude. Overall change can improve environment in towns and provide them with sustainable system of the quality urban green areas.
