Tree Measurements in the Urban Environment: Insights from Traditional and Digital Field Instruments to Smartphone Applications

Urban forests can provide essential environmental and social functions if properly planned managed. Tree inventories measurements are a critical part of assessing monitoring the size, growth, health condition urban trees. In this context, parameters usually collected diameter at breast height (DBH) total height, but additional data about crown dimensions (width, length, projection) required for comprehensive tree assessment. These generally by foresters through field surveys using calipers or tape DBH electronic ipsometer/clinometer to measure size. Greater detail could be achieved digital instrument such as Field-Map, portable computer station, quickly realize dimensional topographic trees forest stands. Additionally, incorporation LIDAR scanner into smartphone iPhone 12 Pro has made device able attributes well spatial in field. study, we tested these 3 different measurement systems sampling an compared them terms measurable parameters, accuracy, cost, time efficiency. Furthermore, discussed pros cons each approach how resulted used evaluate ecosystem services guidance on management order reduce potential risks disservices.
