Evidence & Context
The study reports an estimated stem basal area of 34.9 mb2/ha for all trees with a diameter at breast height (DBH) of •6 10 cm.
Total cross-sectional area of all tree stems in a given stand measured at breast height (1.3 m) per hectare for trees with DBH •6 10 cm
Basal area represents the total cross-sectional area of tree stems at breast height per hectare in a mature-phase rainforest within the tropical & subtropical maritime islands biome under conservation land use.
Selected as a proxy benchmark due to lack of direct data for island conservation areas; represents a mature, complex, and highly functional ecosystem in a protected area.
