RESULTS OF EXPERIMENTS IN REGARD TO RECONSTRUCTION OF SPROUT FORESTS IN SR SERBIA
REZULTATI OGLEDA REKONSTRUKCIJE IZDANAČKIH ŠUMA U NAS
Radulović, Svetislav
One of generally accepted points of view in forestry, is that sprout forests should be considered as uneconomic and out of date form of forest management, and that such forests should be transformed into a high forests, except in the case of protective forest, various wildlife reserves and others. For Serbia, this question is of a great importance, since this type of forest together with brushwood make up 52.2% of entire area under forests. There are two procedures a accepted in practice for achieving this objective. One of them is conversion. It can be used only if this task wants to be achieved only by changing the way of forest tending. The other procedure is reconstruction. This method is used when, besides the change of the way of tending, the change of a species composition is going to be made, considering that existing species are not the best suited for the given soil potential. Which procedure is going to be chosen for a given area depends upon typological investigations, including besides bioecological aspects, and economical components also. This is only one way for transforming sprout forests to high forests, avoiding the errors from the past, made in some countries. Actually it can be done by co-operation of forest science and practice. This paper is dealing only with a problems of reconstruction of sprout forests. At the beginning, is given description of methods and systems, known so far, on reconstruction in the world and here. Then, a review of tests established in some forests in Serbia, by author, is given. They are the following: Šuplja stena near Belgrade, Cer-Vidojevica and Vidlič. In the forests at Šuplja stena, tests were set up in the forest of Hungarian and bitter oak (Ouerceto-farnetum serb. R u d); on Cer in the forest of mountain beech (Fagetum montanum serb. Rud); and also in the forests of sessile oak and hornbeam (Querceto-carpinetum serb. Rud), while in Baljkovac and Vidlič in the forests of mountain beech. At the locality Šuplja stena, method and technique of introduction of Douglas fir, cedar, macedonian and Jeffrey pine have been investigated; in the forests on Cer-Vidojevica and Baljkovac, it was done for Douglas fir, white pine and in the forests on Vidlič, for Douglas fir. Also, method of reconstruction on small patches and introduction of conifers under the cover of existing forests was carried out. At the end, instead conclusions, the author described experiance which was gathered up to now observing the changes occured on these test areas.
