Forest regeneration in post-disaster areas of the Białowieża Forest

Spruce is dying out in large parts of the Białowieża Forest as a result of gradation by the European spruce bark beetle. Because it is forbidden to remove dead spruce trees, they remain on the ground in many places, preventing silviculture work. As it is impossible to conduct artificial regeneration, the European hornbeam has appeared in oak-hornbeam habitats as a result of natural sowing. Its regeneration is very intensive, preventing other tree species from growing. It is becoming hard to maintain species and strata diversity within the forest. This film shows how foresters handle this problem in the management part of the Białowieża Forest.
It turns out that hornbeam has many positive traits as a biocenological intermixture. It is an indispensable ingredient of many tree stands. For example, when it grows under the cover of pines or oaks, it contributes to better cleaning of their stumps from branches. However, silviculture treatment is necessary to limit its expansiveness.
