Technical and economic analysis of Stone pine (Pinus pinea L.) maintenance in urban areas

The Italian Stone pine (Pinus pinea L.) is one of the most common ornamental trees in towns with Mediterranean climates. For example, in the city of Rome (Italy), Pinus is the most common genus, with more than 51,000 trees. This study investigates technical and economic features of maintenance opera...
