Abstract

Abstract: The assessment of the undergrowth state in cuttings is of great interest from the point of view of assessing the success of the subsequent stands restoration. The number, height and spatial location of the undergrowth in the clearing can be effectively studied by using ultra-high-resolution UAVs aerial photography. The aim of the study was to determine of Norway spruce undergrowth parameters on the territory of the allotment after continuous logging on the basis of aerial photography from UAVs. The image was captured using 4 rotary quadrocopter platforms of the Mavic PRO and Phantom 4 PRO V1.0 models with a spatial resolution of 2.56 cm/pixel. Based on the survey materials, an orthophotoplan and a digital terrain model were constructed, which were used to determine the height and number of Norway spruce undergrowth, which turned out to be different from the official data. The spatial placement of the Norway spruce undergrowth was studied using the Poisson method and turned out to be a group one, which requires additional forestry measures to align the placement of the undergrowth over the area of the allotment in order to grow a full-fledged stand of the target breed in the future.
