NATURAL REGENERATION PROCESSES IN OLDGROWTH Pinus peuce FOREST IN THE NATIONAL PARK "PELISTER" ON MT. BABA
Izvod: It is known that natural regeneration is essential for the sustainability of any forest ecosystem. In most of natural and cultivated forest plantations, where natural factors act harmoniously, regeneration is continuous and without difficulty. But in some cases, the disruption of regeneration process may occur and then silvicultural measures may help restore the stand. A particular challenge for the scientific community when they need to solve specific issues is related to regeneration in particularly significant forests, such as the old-growth Pinus peuce forest on Pelister. If we bear in mind that Pinus peuce is a Balkan endemic and tertiary relict species, its significance is even greater. This forest is a special symbol of the National Park as it fulfils a number of functions and values of historical, tourist, recreational and scientific character. There are concentrated oldest Pinus peuce trees dating back to the time when Grizebah August (August Grisebah) in 1839 first discovered Pinus peuce (Gris.) on this site. This species still cherishes the natural environment, but the problems in terms of its natural regeneration are present. Major obstacle appears to be a thick layer of ferns (Pteridium aquilinum) and shrubs (Rubus hirtus), which stifle the development of Pinus peuce regeneration. At some places in the forest, successive natural processes lead to the establishment of fir and beech offspring in the old Pinus peuce forest. These species are more successful in competition against undesirable ground vegetation than Pinus peuce due to their ability to tolerate shade. If managers do not take measures, it is evident that these forests will gradually be populated with fir and beech, which in the long run will change the forest structure and composition. In this way, old Pinus peuce forest can lose its authenticity, characteristics and significance. Therefore, the purpose of this paper is to identify the methods by which, in the optimal and the most natural way, it will be possible to restore the natural regeneration to preserve old Pinus peuce forest in its natural environment and to ensure its sustainability in the long term.
