There exist six green band types in the Czech Republic: lines of trees, area plantation, forest stand, advanced growth (natural succession), shrub bands, grass communities, and all their combinations. The green bands are parts of road-traffic infrastructure and have an impact on the surrounding landscape and natural environment (many positive effects to the nature). First they may serve to the road safety. Consequently principles of new greenery planting and greenery maintenance can be kept carefully. Maintenance must be in keeping with biological properties of trees and shrubs, too. It must be preferred resistant species to the exhaust fumes, oil pollutants, and salting (do not plant non-native or invasive wood species, too). Vegetation around the highways/ roads may be found and grow with the well-advised direction.
