We estimated biomass for different aboveground compartments of a riparian forest in Niquelândia, Goiás, Brazil, and determined expansion factors for necromass, litter, herbaceous layer, tree poles and undergrowth. The tree sample comprised 20 (10 x 10 m) plots of trees with diameter at breast height (dbh) ≥ 5 cm, distributed in four transects (five plots per transect). In each transect, plots were equidistant (50 m apart). For each plot, we sampled the following compartments in five (1 x 1 m) subplots: tree poles (dbh < 5 cm and height (h) ≥ 1.5 m), undergrowth (trees, shrubs and herbs with h < 1.5 m), necromass, and litter. The herbaceous layer sample consisted of one (0.4 x 0.6 m) subplot per plot. Tree biomass was estimated with the equation: ln(AGB) = -10.4398 + 2.1183 * ln(dbh) + 0.8339 * ln(h), where AGB, dbh and h are in Mg, cm, and m, respectively. Dry weight of all other compartments was determined in the laboratory. Tree aboveground biomass was 92.74 Mg ha-1 ( 36.93 Mg ha-1), necromass was 1.2292 Mg ha-1 ( 0.3063 Mg ha-1), litter biomass 2.5675 Mg ha-1 ( 0.2365 Mg ha-1), herbaceous layer biomass was 0.3996 Mg ha-1 ( 0.2288 Mg ha-1), tree-pole biomass was 0.4600 Mg ha-1 ( 0.1761 Mg ha-1), undergrowth biomass was 0.2230 Mg ha-1 ( 0.0925 Mg ha-1). Necromass, litter, herbaceous layer, tree-pole, and undergrowth biomass comprised 0.33%, 0.26%, 0.25%, 0.19%, and 0.10% of tree aboveground biomass, respectively.
