In the lowland area around the city of Brasov, in the heart of Romania, a new urban forest is growing. Reflecting the characteristics of the area, we will be planting oaks, maples, ash trees and wild cherry trees. This is a natural mix of species that will increase the biodiversity of the area and provide shelter and food for local animals, such as birds, small mammals and several species of insects. To measure the benefits of the trees on the area, state-of-the-art sensors will be installed to monitor numerous variables. The main ones will be meteorological, pedological and spectral sensors. They will provide useful data to capture the air, climate and landscape benefits of the future urban forest. In addition, they will give useful indications to make the care of the trees themselves more efficient, so that they grow healthy and strong.
