Popis: Acacia mangium Willd. and Acacia aulacocarpa A. Cunn Ex. Benth are two important Acacias for biomass production.Being multiple-leader (ML) and fast growing species, both species are the best bet for carbon sequestration andbio-energy supplementary. The main objective of this study was to assess the aboveground biomass and to deriveaboveground biomass equations of these species and provenances. Destructive sampling was carried out with 36samples per species and diameter at breast height (Dbh) and categorized into three classes namely small (11-15 cm),medium (16-20 cm) and big (21-25 cm) for A. mangium and 6-10 cm, 11-15 cm and 16-20 cm for A. aulacocarparespectively. A. mangium from SW of Boset WP (PNG) produced 380.83 t/ha of aboveground biomass, Captain BillyRoad (QLD), Bansbach WP (PNG) (224.44 t/ha) and Russel and Gap CK (QLD) (49.63 t/ha) while for A. aulacocarpa;provenance from Arufi E Morehead WP (PNG) (171.88 t/ha), W. Morehead (PNG) (150.90 t/ha), Samford (QLD)(63.87 t/ha) and 3K S Mt. Larcom (QLD) (25.32 t/ha) respectively.
