Dynamics of stand replacing-disturbance and biomass estimation in the Plešné Lake basin

Popis výsledku v původním jazyce

Knowledge about forest decay dynamics is important for a better understanding of major forest ecosystem processes. The main aim of this study was to describe the dynamics of the natural decline of a mountain spruce (Picea abies) forest caused by bark beetle (Ips typographus) infestation in the Plešné Lake basin. Furthermore, we estimated the dry biomass of the trees to get information about wood storage. The spruce forest decay was described in 10 particular years within the period 2000–2015. Individual trees for every year were delineated from aerial photographs to estimate tree position, vitality (healthy, dead, stump) and age class (sapling, young, adult). LiDAR data were acquired (2008, 2011) to estimate tree height, subsequently DBH and volume biomass for 2011 using allometric relationships. At the beginning, in 2000, more than 20 thousand trees were delineated in the basin, where more than 5.8% were dead or dying trees. The strongest bark beetle outbreak occurred prior to 2009, when 74.6% of all trees in the basin were dead. The resulting number of all dead trees was in 2015 67.7%. The average biomass in the basin was 504 t/ha in 2011. The average biomass of particular tree components were 22.4, 26.7, 8.2, 8.6, 294.2, 25.6 and 120.7 t/ha for needles, branch wood, branch bark, fine branches, stem wood, stem bark and roots, respectively.
