Trees play a vital role in improving quality of life in cities, particularly in urban areas where public space is under intense pressure and urbanisation is widespread. By carefully selecting tree species, we not only create variety in structure and flowering, but also provide food and shelter for countless insects, birds and even small mammals. When planted correctly and matched with the right species, trees form the most important link in a functioning ecosystem, benefiting biodiversity. Trees are also essential for maintaining ecological balance and provide countless services for both people and animals, such as purifying the air, creating shade and providing privacy. These valuable ecosystem services make the city a more liveable place.
