Phenology of Dendroflora in the Northern Urban Systems
Northern cities have a small range of tree and shrub species in comparison with the cities of the central and southern areas. It has a negative impact on the aesthetic image of the high latitude cities. The population feels this lack of positive visual emotions. The situation is aggravated by a short vegetation period in the North. Such attributes of the northern dendroflora as the duration of foliation, abundance of blossom, colour of blossom, colour range of autumn leaves are of particular importance.
