Lecture 5.1 How does the urban environment affect trees?

Growing in urban settlements, trees are frequently exposed to various biotic and abiotic stressors, which may negatively affect its health status and growth rate, sometimes even causing a premature mortality. Additionally, future climate change is supposed to worsen climate conditions in urban areas, posing new and unique challenges to urban vegetation. Under influence of urban conditions, trees may develop different physiological and morphological mechanisms to enhance their tolerance to multiple stress factors.

In the following two lectures, Srđan Stojnić (Institute of Lowland Forestry and Environment, University of Novi Sad, Serbia) shares how urban environmental conditions, influence the growth and vitality of trees.
