In this study, some silvicultural and growth characteristics of Cercis siliqustrum L. were assessed at Pol-dokhtar and Shineh in northwest and southwest of Khoramabad in Lorestan province. The study areas were delimitated on topographic map by field observations and using GPS. Data were collected from 30 circular plots of 0.1 ha area, by random sampling design. Quantitative and qualitative characteristics and diameter structure in these sites were evaluated. The results showed that there was significant difference (p≤0.01) between stands in canopy cover, diameter at breast height and the number of sprouts, but no significant difference in stand height between stands. Regeneration form, vitality, disturbance regime, and species composition were also determined. In both site the main regeneration form was coppice and the most important disturbance was limbing. Judas tree would like to appear in northern slopes and establish in mesic humid soils, meanwhile can tolerate drought. Stands diameter structure were uneven aged and irregular.
