The greening of roads has various functions, including cityscape improvement and the preservation of favorable living environments. In recent years, the importance of street trees has been recognized in terms of creating attractive cityscapes and promoting community development. Trees, which are important landmarks and are essential landscape elements, have been preserved and taken care of.

Species of street trees planted in cold areas are those that tolerate severe cold climates. In road and community greening, it is considered important to select tree species that suit the region's characteristics. In studying street trees, it is necessary to conduct research based on the knowledge of which tree species suit each region, including studies on native species.

Orderers and contractors of street tree maintenance do not have sufficient numbers of professional engineers and experienced tree care professionals; therefore, there are some cases in which inappropriate pruning is done on street trees because of a technical decline in personnel.

Under severe government financial conditions, the development and maintenance of road greenery require efficient, effective work execution and labor savings.

The pruning of street trees currently done in cold, snowy areas may be considered excessive. To remedy this, it is necessary for both the orderers and the contractors of street tree maintenance to take appropriate financial measures, secure and educate personnel, and conduct maintenance based on quantitative indexes.

This study proposes management for road greening trees and greenbelt zones on roads in cold, snowy areas.
