Specifičnosti šumske vegetacije planine Radan budućeg prirodnog dobra
The specific character of forest vegetation of the future natural area Radan mountain
Abstract:
Radan mountain massif is located in southeastern Serbia, between the upper flows of the rivers Kosanica and Jablanica. The highest peak of the massif is Šapot (1409 m altitude). Radan mountain is part of the Lece volcanic-andesite massif, the volcanism of which began in the late Oligocene. The geological layer consists of andesites and dacites. Altitudinal distribution of forests on Radan mountain was caused by the geographical position of the mountain, relief, climate, geological layer and soil. Up to 800 m of altitude, the communities of Hungarian oak and Turkey oak are distributed, which are in poor condition and need to be protected from further cutting. The sessile oak forests are few and their fragments are at the altitudes ranging from 700 to 900 m, which are mainly degraded. In the contact area between the oak and beech belt, on the eastern side of Radan mountain, the polydominant forest communities of Turkish hazel and Caucasian linden are distributed in their refugium at the altitudes ranging from 850 to 1000 m. At the area of Delivode, on wetlands at the altitudes ranging from 850 to 950 m, there are the communities of several different species of maple and hornbeam. At the altitudes ranging from 900-1400 m, the mountain beech forests of regional climate character are distributed. Radan mountain is of great interest for science, due to its richness of flora and vegetation and deserves to be protected as a natural area. At the area of Radan mountain the sites with characteristic types of forest ecosystems have been determined. According to their values, the borders of protection regime I (first) at the sites 'Prolom', 'Ripivode' and 'Petrovac', as well as of protection regime II (second) have been determined.
