Description Studies predicting diameter at breast height (dbh) from stump height measurements are numerous but none had been conducted in Malinau distric, East Kalimantan. The objective of this study is to develop a relationship between stump height and dbh in order to predict dbh from diameter at estimated stump height (dsh) for those species being harvested. Analysis of stump height data (170 samples) established the mean stump height for the study area at 111 cm. This figure was then used to measure dsh for a total of 800 sample trees, dbh was measured at 1.3 m for all sample trees. General linear model equation were used to develop relationships between dbh and dsh. The coefficients for determining dbh range between 0.96 and 0.99.
