Abstract

The effects of climate change are especially felt in urban areas. Rising temperatures and changing precipitation patterns are challenging the maintenance of green oases in cities. However, urban trees are becoming increasingly important in mitigating these negative climatic effects, as they offer positive cooling potential to the surrounding area through the shading and evaporation capacity of the vegetation. At the same time, they are also susceptible to these weather extremes such as summer heat and drought, resulting in high surface runoff and low infiltration rates. This leads to the problem that native urban tree species, such as large-leaved lime (Tilia platyphyllos) and sycamore maple (Acer pseudoplatanus), are reaching the limits of their adaptability. In contrast, tree species native to south-eastern Europe are better equipped to cope with changing climatic conditions through various adaptations, such as leaf orientation in response to high levels of solar radiation. One potential adaptation strategy is the use of alternate-leaf tree species, which could mitigate the adverse effects of climate change in urban areas and improve the quality of life for residents. In particular, the silver lime (Tilia tomentosa) is becoming increasingly important in this context. It can turn the silvery underside of its leaves upwards when exposed to strong sunlight, leading to a change in the albedo and a possible reduction in surface temperatures in the crown area.
