Räumliche Verteilung von Rotbuche (Fagus sylvatica) und Traubeneiche (Quercus petraea) und deren zoochores Ausbreitungspotential mit Blick auf die Minimierung der Eingriffsintensität beim Waldumbau in Nadelwäldern mit Naturschutzstatus
The spatial distribution of European beech (Fagus sylvatica) and Sessile oak (Quercus petraea) and and their potential zoochor dispersion in view of a possible minimization of the intensity of silvicultural operations during the conversion of protected coniferous forest stands
The conversion of protected forest stands holds a considerable potential for conflicts. On the one hand, the conversion to a near-natural forest structure and species composition should be realized by actively introducing species of today's potential natural vegetation, while on the other hand the forest stands must be disturbed as little as possible (conservation of natural processes). Especially within the development zones of national parks it is of importance to gain more insight into the dispersion of natural regeneration of beech and oak wiin non-natural stands of spruce and pine, respectively. While the mainly zoochor dispersion of oak species has been fairly well studied, knowledge about the zoochory of beech is sparse. We will investigate the silviculturally relevant dispersion distances and the respective number of seeds as well as potential preferences of the zoochor vectors for so-called "safe-sites" featuring specific combinations of small-scale characterstics.
By assessing this potential, disturbances in forest ecosystems caused by active large-scale forest conversion can be reduced by minimizing the intensity of silvicultural operations in protected areas such as national parks.
