Wood anatomical features of Celtis australis L., one of forest trees growing naturally and having gradually lessspreading areas, constituted our research subject. The materials were taken from the Mediterranean region andEuxine sub-region containing the west part of the Black Sea region in Euro-Siberian flora area, which is fromtwo of Turkey’s three principal flora areas. Wood specimens from different altitudes were taken to be able todetermine the variations emerging on the anatomical features of wood depending on altitude.“Vulnerability” and “mesomorphy” values were determined in context of ecological wood anatomy of thespecies examined. The mesomorphy value of the late wood of Celtis australis L. is more at high altitude (921m;541,96) than at low altitude (40m; 200,21). Insufficient amount of sample trees made impossible to evaluatesome ecological trends depending on altitude, nevertheless, the results of Variance analysis and Duncan testapplied made possible to evaluate some outcomes having emerged relating to vessel features ecologically.Summer wood vessel diameters at high altitudes (921m, 55,15μm) are higher in comparison with low altitudes (40m, 33,1μm) in Mediterranean region. Additionally, significant difference was found in vessel groupings.Vessel grouping is more at low altitudes (40m, 8,3) than at high altitudes (921m; 3,7) in this region. Since summer wood at low altitudes occurred within too dry conditions in comparison with high altitudes, grouping index was high as a requirement to provide safety in water conduction.
