Young Silver Birch Grows Faster and Allocates Higher Portion of Biomass into Stem Than Norway Spruce, a Case Study from a Post-Disturbance Forest by Bohdan Konôpka, Jozef Pajtík, Vladimír Šebeň, Peter Surový, Katarína Merganičová

“…At the same time, birch trees had a 40% greater diameter increment and a 30% denser stem wood than spruce. As for aboveground biomass production, the contribution of the stem as an economically important component was greater in birch than spruce. …”

Very High Density Point Clouds from UAV Laser Scanning for Automatic Tree Stem Detection and Direct Diameter Measurement by Karel Kuželka, Martin Slavík, Peter Surový

“…We detected correctly 99% and 100% of all trees in research plots for spruce and pine, respectively, and were able to estimate diameters for 99% of spruces and 98% of pines with mean bias error of −0.1 cm (−1%) and RMSE of 6.0 cm (19%), using the best performing method, RTLS. …”

UAV Laser Scans Allow Detection of Morphological Changes in Tree Canopy by Martin Slavík, Karel Kuželka, Roman Modlinger, Ivana Tomášková, Peter Surový

“…In a multi-temporal series of three ULS datasets, we detected a synchronized reversible change in the inclination angles of the branches of 43 dead trees in a stand of blue spruce (<i>Picea pungens</i> Engelm.). The observed phenomenon has important consequences for both tree physiology and forest remote sensing (RS). …”

Comparison of Individual Sensors in the Electronic Nose for Stress Detection in Forest Stands by Tereza Hüttnerová, Sebastian Paczkowski, Tarek Neubert, Anna Jirošová, Peter Surový

“…Due to prolonged droughts in the last years in Europe, European forest stands significantly lost vitality, and their health condition deteriorated, leading to high mortality rates, especially, but not limited to, Norway spruce. This phenomenon is growing, and new regions are being affected; thus, it is necessary to identify stress in the early stages when actions can be taken to protect the forest and living trees. …”
