Management practices are one of the most important factors affecting forest structure and *** in southern United states manage forests using appropriately sized areas,to meet management objectives that include economic return,sustainability,and esthetic *** networks spatially designate the socioenvironmental elements for the forests,which represented and aggregated as forest management *** networks are widely used for managing forests by setting logging roads and *** propose that common types of forest management are practiced in road-delineated units that can be determined by remote sensing satellite imagery coupled with crowd-sourced road network *** sensors do not always capture roadcaused canopy openings,so it is difficult to delineate ecologically relevant units based only on satellite *** integrating citizen-based road networks with the National Land Cover Database,we mapped road-delineated management units across the regional landscape and analyzed the size frequency distribution of management *** found the road-delineated units smaller than 0.5 ha comprised 64%of the number of units,but only0.98%of the total forest *** also applied a statistical similarity test(warren's index)to access the equivalency of road-delineated units with forest disturbances by simulating a serious of neutral *** outputs showed that the whole southeastern *** the probability of road-delineated unit of 0.44 and production forests overlapped significantly with disturbance areas with an average probability of 0.50.
