The environmental conditions in urban landscapes are, however,very different from the natural conditions that the tree species are adapted to. This poses big challenges tothe urban forestry in its efforts to create healthy and valuable trees in urban landscapes. Only throughimplementing some important measures we can ensure high survival rate of saplings and well-being andlongevity of urban trees.
