The structure and silvicultural demands of two narrow-leaved ash stands of different origin and age was studied in the Special Nature Reserve Gornje Podunavlje (Serbia), in the area of protected against floods. The elements of growth and structure in the 38-year-old natural stand in the area of previous wet depressions and in the 74-year-old artificial stand on the site of the forest Fraxineto-Ulmetum effusae Slav. 1952 point to very high production effects. The diameter distribution of trees is characterized by slight skewness and low kurtosis, and the height distribution of trees is characterized by left skewness. 154 future trees per hectare were selected in the 38-year-old stand and in the twice older stand with the same initial selection criterion, the number of future trees per hectare was 82. The stands were treated by selection thinning of moderate weight (25% per G), i.e. low thinning based on q(d)=0.83-0.85. Thinning volume amounted to 109.8 cubic meter/ha in 38-year-old stand, and 207.4 cubic meter/ha in the 74-year-old stand.
