D. Kajba, I. Anić, D. Pfeifer: POTRAJNOST I OČUVANJE GENOFONDA S POSEBNIM OSVRTOM ... Šumarski list br. 5–6, CXXIX (2005), 271-278 cial is the selection of plus variants from natural juvenile European Black Poplar populations, since in this manner it’s possible to select new genotypes, well adapted to specific local sites. Regeneration strategy should be guided by the principle of replacing the plantations of Euroamerican Poplars with European Black Poplar, all in accordance to forest silvicultural plans. The sites in whitch the water regime allows continuous regenerations of Poplars, appropriate methods of renewall and activity dynamics should be predicted and established by these plans. For fulfilling the goal of total stand replacement, a period of at least 50 years should be predicted. In the meantime, forest production of Euroamerican poplar (P. × canadensis) should continue on approx. 25 % of total surfaces.
