Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 9 benchmarks together — the OptimalRange form drives the primary score, while 8 guard(s) constrain the result.
Evidence & Context
The study reports an estimated stem basal area of 34.9 m²/ha for all trees with a diameter at breast height (DBH) of ≥ 10 cm.
Total cross-sectional area of all tree stems in a given stand, measured at breast height (1.3 meters above ground), expressed per unit of land area.
Basal area is the total cross-sectional area of all tree stems in a stand, measured at breast height and expressed per hectare in the tropical and subtropical maritime island biome under conservation land use.
Selected as a proxy benchmark because direct data for island conservation areas was not found; DRO represents a mature, complex, and highly functional ecosystem in a protected area.
