This dataset was collected within a Scots pine forest site in Brandenburg, North-Eastern Germany, using handheld LiDAR systems, and contains multi-temporal processed point clouds, compressed '.laz' data type. The data are suitable for reproducible research on forest inventory accuracy, scanning optimization, research on PLS-based forest structure analysis, change detection, digital forest twin development, and data fusion with other LiDAR (light detection and ranging) sources. Personal laser scanning (PLS) data were collected using a handheld/mobile LiDAR system following parallel geometric scanning patterns. Scans were conducted on plots of varying sizes (each ~ 1 hectare) with 12.5-25 m transect spacings. Data acquisition was performed before (2023-09) and after (2024-09) thinning operations (timber harvesting) to enable temporal comparison.
