Autonomous drone fleets replacing field-based forest inventory
#1Commercial UAV platforms with LiDAR (Velodyne, Livox) and multispectral sensors (MicaSense RedEdge) can now complete forest inventory surveys — measuring tree height, crown area, basal area, and stem density — over hundreds of acres per flight day at a cost of $5-15/acre, compared to $50-200/acre for ground-based crew surveys. The USDA Forest Service's Forest Inventory and Analysis program has formally evaluated drone-assisted inventory in the Interior West and Pacific Northwest, with several regions now incorporating UAV data into operational workflows. Companies including Silvacom, Indufor, and Forsite are selling commercial drone inventory services to forest landowners, directly competing with agency and consulting technician labor.
