Authors present recommendations, which can be helpful in fight against black cherry both in the Zielonka Experimental Forest Division and on the area of other regions. They are based on estimation of methods of fight against Prunus serotina within the Zielonka Experimental Forest Division, known up to the present and on the works on forest typology units and on plant communities of the described forest division. Investigations show that physical and chemical methods used till now have only significantly delimited the expansion of that plant. Achieving stand composition consistent with potential vegetation and receiving multilayer structure of stands seem to be the most effective ways of black cherry control. European hornbeam, European beech and notably pedunculate and sessile oaks, as the species shading on forest floor, are of great importance in these processes. Mentioned species should appear naturally on the sites of deciduous fresh forests. The authors suggest increasing their participation on the sites of fresh forest, and with reference to oak and beech on the site of fresh coniferous mixed forest, too. Protecting Scotch pine on these sites within the investigated area is, however, economically profitable, promotes spread of P. serotina. It may cause adverse effects both natural and financial.
