Seedling height (SH),root-collar diameter (RCD), and number of reproductions (NR) were ex-amined in two years natural regeneration areas sam-pled over a slope(S)range(low, S S>15%;high,S>30%o)of Anatolian black pine [Pinus nigra Arnold. subsp. pallasiana (Lamb.)Holmboe] to contribute to silvicultural practices of the species in this study. Large differences supported also by analysis of variance(ANOVA)were found for SH, RCD and NR among slope ranges and within range. Middle slope showed highest SH(14.49 cm) and RCD(5.32 mm)performances, while they were lowest(11.87 cm and 4.69 mm) in the highest slope. Numbers of reproduc-tion were ordered，0.58/m²，0.27 and 0.18 seedlings from low to high slope. Results of ANOVA showed statistically signif-icant (p<0.05)differences among slope ranges and within range for SH and RCD.Positive and signifi-cant(p<0.05)relations were found between SH and RCD in sampled areas and slope range. Results of the study were discussed based on climate change,and silviculturalpractices of the spe-cies.
