Urban influence effect of dominant native tree species growth

Abstract

Urban climate are different from wildlife. These differences made some influence on tree growth. Do urban environment affect the morphological, dendrometrical parameters of trees, phenology phases, chemical composition of leaves, intensity of leaf litter decomposition, soil acidification? To answer this question, we have analyzed the growth of the four dominant native deciduous tree species Tilia cordata, Acer platanoides, Betula pendula and Quercus robur. Research has focused on different environments. Measurement were made in urban parks, street trees and forest stands in Kaunas, Lithuania. The results show that the all our observable parameters in urban trees were differed from forest stand trees. Charges are differences depending on tree species. We conclude that the urban microclimate affect growth of native trees.
