Stand density and species diversity are two indicators that highly related to forest productivity. However, the effect of those variables on productivity community is rarely documented. This study evaluates influence stand timber production carbon stock in forest. The area was located Madiun District. A field survey conducted four different sites, i.e. Morang, Kuwiran, Randualas, Kare. sampling technique by quadrat method using a sample plot size 25 m x m. number plots used this 64 units, which were evenly distributed every site. Comparison attributes among sites examined Kruskal-Wallis test followed Kruskal-Nemenyi effects assessed separately for each parameter generalized least square regression test. process statistical analysis applied significance level 5%. Results show significant difference volume, aboveground biomass, (P<0.05). also recorded meaningful forest, wherein provided higher (R2 = 0.68; P<0.05) than 0.26; P<0.05).
