Růst a zdravotní stav výsadeb jedle bělokoré (Abies alba Mill.) na slunečných a zastíněných stanovištních podmínkách v Beskydech

Silver fir (Abies alba Mill.) used to be an important species in the region of what is the Czech Republic today. Its return to the forest ecosystem is more than desirable, mainly because it can be utilised in the transition of forest management to close-to-nature management in establishing multistorey, uneven-aged or mixed forests. A total of 15 unestablished stands arising on clear-cut areas in the Beskydy Mts. (caused by storms and the subsequent gradation of bark beetle) in the period 2015–2018 were selected, some of which were established in large clear-cut areas without being influenced by standing mature stands, and others in small clear-cut areas that were influenced by standing mature stands. In 2019, heights, height increments and lengths of the longest branches of all fir were measured and their vitality estimated. Growth variability and health status of the fir trees indicate that it is more appropriate to plant fir on small clear-cut gaps located inside stands. The protective effect of a mature stand contributes to faster growth of trees and better health status. Moreover, plagiotropism (due to excessive shading), which had been a major concern, was not confirmed.
