D. Kapec: UTJECAJ INTENZITETA SUŠENJA, MIKRORELJEFA I SAVSKE POPLAVNE VODE ... Šumarski list br. 9–10, CXXX (2006), 425-443 The second part concerns research microrelief of compartment 166 a,crosssection through,stem number distribution,height curve and the border of drying zone with the map of drying,contour line 98,00 m height above the sea level and directions of Sava input flood waters.The places of 23 compartments below that contour line had total dieback and they make the whole with compartments of partial clearly dieback around named drying zonas whose directions are in correlation with available Sava’s flood waters on october 27 of 1964. The third part according research results proved that total growing stock volume of all stands in the whole management unit after big dropping through 45 years was growth steeper and steeper and now reaches former form and better age-class proportions with a positive trend for the future. A detailed analysis of the increment and realized etat in the forest Žutica has confirmed that etat was realized by thinning and sanitar feeling very carefully with success and in normal relation, so already 20 years in this way one third of increment could realized by thining, 2/3 of it accumulated in the growing stock. The former increment in the management unit is initially small in1958 (4,5m3/ha) then it reaches its culmination in 1978 (8,53m3/ha) later fall slowly (7,28m3/ha) until it reaches 7,9 m3/ha 1998 (an average normala is 7,29 m3/ha). Composition of shares wood stock and areas pedunculate oak with other trees species shows dominant role of pedunculate oak with a little increase share of fild ash and black alder in spite of earlier great dieback.Oscillations of the openness management unit from 1958 to 1998 former is initialy small (1,46 km/1000 ha), then it reaches its culmination in 1998 (15,16 km/1000 ha). Unfortunately that openness is not optimal for total forest area and management forest because the roads has constructed of primary importance for exploatation oil and gas by access to numerous wells (276).
