stand decline - Opis:
- The study aimed at analyzing the oak population structure was performed on the 29−hectare plot representing stands dominated by spruce in the strict reserve of the Białowieża National Park. It revealed that oaks represent two distinct cohorts: the old, emerged in the late 1800s, and the new that is being established in the area subject to mass decline of spruce. We suggest that the first regeneration wave was the result of ceasing the frequent ground fire regime that prevented the regeneration of trees except for pine. The current wave has been prompted by a set of changes in the habitat quality, following the breakdown of dense spruce−dominated stands. These changes, such as access to sunlight, accelerated decomposition of spruce litter, local exposure of mineral soil, and protective structures of lying spruce logs, provide regeneration advantage to oak and other intolerant species.
